[PATCH 02/37] perf bpf: Do not attach a BPF prog to a tracepoint if its name starts with !

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

With BPF_MAP_TYPE_PROG_ARRAY + bpf_tail_call() we want to have BPF
programs, i.e. functions in a object file that perf's BPF loader
shouldn't try to attach to anything, i.e. "!syscalls:sys_enter_open"
should just stay there, not be attached to a tracepoint with that name,
it'll be used by, for instance, 'perf trace' to associate with syscalls
that copy, in addition to the syscall raw args, a filename pointed by
the first arg, i.e. multiple syscalls that need copying the same pointer
arg in the same way, as a filename, for instance, will share the same
BPF program/function.

Right now when perf's BPF loader sees a function with a name
"sys:name" it'll look for a tracepoint and will associate that BPF
program with it, say:

  SEC("raw_syscalls:sys_enter")
  int sys_enter(struct syscall_enter_args *args)
  {
     //SNIP
  }

Will crate a perf_evsel tracepoint event and then associate with it that
BPF program.

This convention at some point will switch to the one used by the BPF
loader in libbpf, but to experiment with BPF_MAP_TYPE_PROG_ARRAY in
'perf trace' lets do this, that will not require changing too much
stuff.

[PATCH 04/37] perf trace: Add pointer to BPF object containing __augmented_syscalls__

[Arnaldo Carvalho de Melo]

So that we can use it when looking for other components of that object
file, such as other programs to add to the BPF_MAP_TYPE_PROG_ARRAY and
use with bpf_tail_call().

[PATCH 05/37] perf trace: Look up maps just on the __augmented_syscalls__ BPF object

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

We can conceivably have multiple BPF object files for other purposes, so
better look just on the BPF object containing the __augmented_syscalls__
map for all things augmented_syscalls related.

[PATCH 07/37] perf trace: Add BPF handler for unaugmented syscalls

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Will be used to assign to syscalls that don't need augmentation, i.e.
those with just integer args.

All syscalls will be in a BPF_MAP_TYPE_PROG_ARRAY, and the
bpf_tail_call() keyed by the syscall id will either find nothing in
place, which means the syscall is being filtered, or a function that
will either add things like filenames to the ring buffer, right after
the raw syscall args, or be this unaugmented handler that will just
return 1, meaning don't filter the original
raw_syscalls:sys_{enter,exit} tracepoint.

For now it is not really being used, this is just leg work to break the
patch into smaller pieces.

It introduces a trace__find_bpf_program_by_title() helper that in turn
uses libbpf's bpf_object__find_program_by_title() on the BPF object with
the __augmented_syscalls__ map. "title" is how libbpf calls the SEC()
argument for functions, i.e. the ELF section that follows a convention
to specify what BPF program (a function with this SEC() marking) should
be connected to which tracepoint, kprobes, etc.

In perf anything that is of the form SEC("sys:event_name") will be
connected to that tracepoint by perf's BPF loader.

In this case its something that will be bpf_tail_call()ed from either
the "raw_syscalls:sys_enter" or "raw_syscall:sys_exit" tracepoints, so
its named "!raw_syscalls:unaugmented" to convey that idea, i.e. its not
going to be directly attached to a tracepoint, thus it starts with a
"!".

[PATCH 08/37] perf trace: Allow specifying the bpf prog to augment specific syscalls

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

This is a step in the direction of being able to use a
BPF_MAP_TYPE_PROG_ARRAY to handle syscalls that need to copy pointer
payloads in addition to the raw tracepoint syscall args.

There is a first example in
tools/perf/examples/bpf/augmented_raw_syscalls.c for the 'open' syscall.

Next step is to introduce the prog array map and use this 'open'
augmenter, then use that augmenter in other syscalls that also only copy
the first arg as a string, and then show how to use with a syscall that
reads more than one filename, like 'rename', etc.

[PATCH 09/37] perf trace: Put the per-syscall entry/exit prog_array BPF map infrastructure in place

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

I.e. look for "syscalls_sys_enter" and "syscalls_sys_exit" BPF maps of
type PROG_ARRAY and populate it with the handlers as specified per
syscall, for now only 'open' is wiring it to something, in time all
syscalls that need to copy arguments entering a syscall or returning
from one will set these to the right handlers, reusing when possible
pre-existing ones.

Next step is to use bpf_tail_call() into that.

[PATCH 10/37] perf trace: Handle raw_syscalls:sys_enter just like the BPF_OUTPUT augmented event

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

So, we use a PERF_COUNT_SW_BPF_OUTPUT to output the augmented sys_enter
payload, i.e. to output more than just the raw syscall args, and if
something goes wrong when handling an unfiltered syscall, we bail out
and just return 1 in the bpf program associated with
raw_syscalls:sys_enter, meaning, don't filter that tracepoint, in which
case what will appear in the perf ring buffer isn't the BPF_OUTPUT
event, but the original raw_syscalls:sys_enter event with its normal
payload.

Now that we're switching to using a bpf_tail_call +
BPF_MAP_TYPE_PROG_ARRAY we're going to use this in the common case, so a
bug where raw_syscalls:sys_enter wasn't being handled by
trace__sys_enter() surfaced and for  that case, instead of using the
strace-like augmenter (trace__sys_enter()), we continued to use the
normal generic tracepoint handler:

  (gdb) p evsel
  $2 = (struct perf_evsel *) 0xc03e40
  (gdb) p evsel->name
  $3 = 0xbc56c0 "raw_syscalls:sys_enter"
  (gdb) p ((struct perf_evsel *) 0xc03e40)->name
  $4 = 0xbc56c0 "raw_syscalls:sys_enter"
  (gdb) p ((struct perf_evsel *) 0xc03e40)->handler
  $5 = (void *) 0x495eb3 <trace__event_handler>

This resulted in this:

     0.027 raw_syscalls:sys_enter:NR 12 (0, 7fcfcac64c9b, 4d, 7fcfcac64c9b, 7fcfcac6ce00, 19)
     ... [continued]: brk())                = 0x563b88677000

I.e. only the sys_exit tracepoint was being properly handled, but since
the sys_enter went to the generic trace__event_handler() we printed it
using libtraceevent's formatter instead of 'perf trace's strace-like
one.

Fix it by setting trace__sys_enter() as the handler for
raw_syscalls:sys_enter and setup the tp_field tracepoint field
accessors.

Now, to test it we just make raw_syscalls:sys_enter return 1 right after
checking if the pid is filtered, making it not use
bpf_perf_output_event() but rather ask for the tracepoint not to be
filtered and the result is the expected one:

  brk(NULL)                               = 0x556f42d6e000

I.e. raw_syscalls:sys_enter returns 1, gets handled by
trace__sys_enter() and gets it combined with the raw_syscalls:sys_exit
in a strace-like way.

[PATCH 12/37] perf augmented_raw_syscalls: Switch to using BPF_MAP_TYPE_PROG_ARRAY

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Trying to control what arguments to copy, which ones were strings, etc
all from userspace via maps went nowhere, lots of difficulties to get
the verifier satisfied, so use what the fine BPF guys designed for such
a syscall handling mechanism: bpf_tail_call + BPF_MAP_TYPE_PROG_ARRAY.

The series leading to this should have explained it thoroughly, but the
end result, explained via gdb should help understand this:

Now its a matter of automagically assigning the BPF programs copying
syscall arg pointers to functions that are "open"-like (i.e. that need
only the first syscall arg copied as a string), or "openat"-like (2nd
arg, etc).

End result in tool output:

[PATCH 13/37] perf augmented_raw_syscalls: Support copying two string syscall args

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Starting with the renameat and renameat2 syscall, that both receive as
second and fourth parameters a pathname:

  # perf trace -e rename* mv one ANOTHER
  LLVM: dumping /home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o
  mv: cannot stat 'one': No such file or directory
  renameat2(AT_FDCWD, "one", AT_FDCWD, "ANOTHER", RENAME_NOREPLACE) = -1 ENOENT (No such file or directory)
  #

Since the per CPU scratch buffer map has space for two maximum sized
pathnames, the verifier is satisfied that there will be no overrun.

[PATCH 14/37] perf trace: Look for default name for entries in the syscalls prog array

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

I.e. just look for "!syscalls:sys_enter_" or "exit_" plus the syscall
name, that way we need just to add entries to the
augmented_raw_syscalls.c BPF source to add handlers.

[PATCH 19/37] perf tools: Fix proper buffer size for feature processing

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

After Song Liu's segfault fix for pipe mode, Arnaldo reported following
error:

  # perf record -o - | perf script
  0x514 [0x1ac]: failed to process type: 80

It's caused by wrong buffer size setup in feature processing, which
makes cpu topology feature fail, because it's using buffer size to
recognize its header version.

[PATCH 20/37] perf stat: Fix segfault for event group in repeat mode

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@redhat.com>

Numfor Mbiziwo-Tiapo reported segfault on stat of event group in repeat
mode:

  # perf stat -e '{cycles,instructions}' -r 10 ls

It's caused by memory corruption due to not cleaned evsel's id array and
index, which needs to be rebuilt in every stat iteration. Currently the
ids index grows, while the array (which is also not freed) has the same
size.

Fixing this by releasing id array and zeroing ids index in
perf_evsel__close function.

We also need to keep the evsel_list alive for stat record (which is
disabled in repeat mode).

[PATCH 21/37] perf augmented_raw_syscalls: Augment sockaddr arg in 'connect'

We already had a beautifier for an augmented sockaddr payload, but that
was when we were hooking on each syscalls:sys_enter_foo tracepoints,
since now we're almost doing that by doing a tail call from
raw_syscalls:sys_enter, its almost the same, we can reuse it straight
away.

[PATCH 23/37] perf trace beauty: Disable fd->pathname when close() not enabled

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

As we invalidate the fd->pathname table in the SCA_CLOSE_FD beautifier,
if we don't have it we may end up keeping an fd->pathname association
that then gets misprinted.

The previous behaviour continues when the close() syscall is enabled,
which may still be a a problem if we lose records (i.e. we may lose a
'close' record and then get that fd reused by socket()) but then the
tool will notify that records are being lost and the user will be warned
that some of the heuristics will fall apart.

[PATCH 27/37] perf stat: Always separate stalled cycles per insn

[Arnaldo Carvalho de Melo]

From: Cong Wang <xiyou.wangcong@gmail.com>

The "stalled cycles per insn" is appended to "instructions" when the CPU
has this hardware counter directly. We should always make it a separate
line, which also aligns to the output when we hit the "if (total &&
avg)" branch.

Before:

  $ sudo perf stat --all-cpus --field-separator , --log-fd 1 -einstructions,cycles -- sleep 1
  4565048704,,instructions,64114578096,100.00,1.34,insn per cycle,,
  3396325133,,cycles,64146628546,100.00,,

After:

  $ sudo ./tools/perf/perf stat --all-cpus --field-separator , --log-fd 1 -einstructions,cycles -- sleep 1
  6721924,,instructions,24026790339,100.00,0.22,insn per cycle

[PATCH 30/37] perf trace: Forward error codes when trying to read syscall info

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

We iterate thru the syscall table produced from the kernel syscall
tables reading info, propagate the error and add to the debug message.

This helps in fixing further bugs, such as failing to read the
"sendfile" syscall info when it really should try the aliasm
"sendfile64".

  Problems reading syscall 40: 2 (No such file or directory)(sendfile) information

  # grep sendfile /tmp/build/perf/arch/x86/include/generated/asm/syscalls_64.c
	[40] = "sendfile",
  #

I.e. in the tracefs format file for the syscall tracepoints we have it
as sendfile64:

  # find /sys -type f -name format | grep sendfile
  /sys/kernel/debug/tracing/events/syscalls/sys_enter_sendfile64/format
  /sys/kernel/debug/tracing/events/syscalls/sys_exit_sendfile64/format
  #

But as "sendfile" in the file used to build the syscall table used in
perf:

  $ grep sendfile arch/x86/entry/syscalls/syscall_64.tbl
  40	common	sendfile		__x64_sys_sendfile64
  $

So we need to add, in followup patches, aliases in 'perf trace' syscall
data structures to cope with thie.

[PATCH 31/37] perf trace: Mark syscall ids that are not allocated to avoid unnecessary error messages

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

There are holes in syscall tables with IDs not associated with any
syscall, mark those when trying to read information for syscalls, which
could happen when iterating thru all syscalls from 0 to the highest
numbered syscall id.

[PATCH 32/37] perf trace: Preallocate the syscall table

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

We'll continue reading its details from tracefs as we need it, but
preallocate the whole thing otherwise we may realloc and end up with
pointers to the previous buffer.

I.e. in an upcoming algorithm we'll look for syscalls that have function
signatures that are similar to a given syscall to see if we can reuse
its BPF augmenter, so we may be at syscall 42, having a 'struct syscall'
pointing to that slot in trace->syscalls.table[] and try to read the
slot for an yet unread syscall, which would realloc that table to read
the info for syscall 43, say, which would trigger a realoc of
trace->syscalls.table[], and then the pointer we had for syscall 42
would be pointing to the previous block of memory. b00m.

[PATCH 33/37] perf trace: Reuse BPF augmenters from syscalls with similar args signature

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

We have an augmenter for the "open" syscall, which has just one pointer,
in the first argument, a "const char *", so any other syscall that has
just one pointer and that is the first can reuse the "open" BPF
augmenter program.

Even more, syscalls that get two pointers with the first being a string
can reuse "open"'s BPF augmenter till we have an augmenter that better
matches that syscall with two pointers.

With this the few augmenters we have, for open (first arg is a string),
openat (2nd arg is a string), renameat (2nd and 4th are strings) can be
reused by a lot of syscalls, ditto for "bind" reusing "connect" because
both have the 2nd argument as a sockaddr and the 3rd as its len.

Lets see how this makes the "bind" syscall reuse the "connect" BPF prog
augmenter found in tools/perf/examples/bpf/augmented_raw_syscalls.c:

  # perf trace -e bind,connect systemctl restart sshd
  connect(3, { .family: PF_LOCAL, path: /run/systemd/private }, 23) = 0
  #

Oh, it just connects to some daemon, so we better do it system wide and then
stop/start sshd:

  # perf trace -e bind,connect
  systemctl/10124 connect(3, { .family: PF_LOCAL, path: /run/systemd/private }, 23) = 0
  sshd/10102 connect(7, { .family: PF_LOCAL, path: /dev/log }, 110) = 0

[PATCH 34/37] perf trace: Add "sendfile64" alias to the "sendfile" syscall

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

We were looking in tracefs for:

  /sys/kernel/debug/tracing/events/syscalls/sys_enter_sendfile/format when

what is there is just

  /sys/kernel/debug/tracing/events/syscalls/sys_enter_sendfile/format

Its the same id, 40 in x86_64, so just add an alias and let the existing
logic take care of that.

[PATCH 35/37] perf probe: Set pev->nargs to zero after freeing pev->args entries

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

So that, when perf_add_probe_events() fails, like in:

  # perf probe icmp_rcv:64 "type=icmph->type"
  Failed to find 'icmph' in this function.
    Error: Failed to add events.
  Segmentation fault (core dumped)
  #

We don't segfault.

clear_perf_probe_event() was zeroing the whole pev, and since the switch
to zfree() for the members in the pev, that memset() was removed, which
left nargs with its original value, in the above case 1.

With the memset the same pev could be passed to clear_perf_probe_event()
multiple times, since all it would have would be zeroes, and free()
accepts zero, the loop would not happen and we would just memset it
again to zeroes.

Without it we got that segfault, so zero nargs to keep it like it was,
next cset will avoid calling clear_perf_probe_event() for the same pevs
in case of failure.

[PATCH 36/37] perf probe: Avoid calling freeing routine multiple times for same pointer

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

When perf_add_probe_events() we call cleanup_perf_probe_events() for the
pev pointer it receives, then, as part of handling this failure the main
'perf probe' goes on and calls cleanup_params() and that will again call
cleanup_perf_probe_events()for the same pointer, so just set nevents to
zero when handling the failure of perf_add_probe_events() to avoid the
double free.

  perf flamegraph: Use /bin/bash for report and record scripts (2020-05-05 16:35:32 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf record:

  - Introduce --switch-output-event to use arbitrary events to be setup
    and read from a side band thread and, when they take place a signal
    be sent to the main 'perf record' thread, reusing the --switch-output
    code to take perf.data snapshots from the --overwrite ring buffer, e.g.:

	# perf record --overwrite -e sched:* \
		      --switch-output-event syscalls:*connect* \
		      workload

    will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
    connect syscalls.

  Stephane Eranian:

  - Add --num-synthesize-threads option to control degree of parallelism of the
    synthesize_mmap() code which is scanning /proc/PID/task/PID/maps and can be
    time consuming. This mimics pre-existing behaviour in 'perf top'.

Intel PT:

  Adrian Hunter:

  - Add support for synthesizing branch stacks for regular events (cycles,
    instructions, etc) from Intel PT data.

perf bench:

  Ian Rogers:

  - Add a multi-threaded synthesize benchmark.

  - Add kallsyms parsing benchmark.

  Tommi Rantala:

  - Fix div-by-zero if runtime is zero.

perf synthetic events:

  - Remove use of sscanf from /proc reading when parsing pre-existing
    threads to generate synthetic PERF_RECORD_{FORK,MMAP,COMM,etc} events.

tools api:

  - Add a lightweight buffered reading API.

libsymbols:

  - Parse kallsyms using new lightweight buffered reading io API.

perf parse-events:

  - Fix memory leaks found on parse_events.

perf mem2node:

  - Avoid double free related to realloc().

perf stat:

  Jin Yao:

  - Zero all the 'ena' and 'run' array slot stats for interval mode.

  - Improve runtime stat for interval mode

  Kajol Jain:

  - Enable Hz/hz printing for --metric-only option

  - Enhance JSON/metric infrastructure to handle "?".

perf tests:

  Kajol Jain:

  - Added test for runtime param in metric expression.

  Tommi Rantala:

  - Fix data path in the session topology test.

perf vendor events power9:

  Kajol Jain:

 - Add hv_24x7 socket/chip level metric events

Coresight:

  Leo Yan:

  - Move definition of 'traceid_list' global variable from header file.

  Mike Leach:

  - Update to build with latest opencsd version.

perf pmu:

  Shaokun Zhang:

  - Fix function name in comment, its get_cpuid_str(), not get_cpustr()

  Stephane Eranian:

  - Add perf_pmu__find_by_type() helper

perf script:

  Stephane Eranian:

  - Remove extraneous newline in perf_sample__fprintf_regs().

  Ian Rogers:

  - Avoid NULL dereference on symbol.

tools feature:

  Stephane Eranian:

  - Add support for detecting libpfm4.

perf symbol:

  Thomas Richter:

  - Fix kernel symbol address display in TUI verbose mode.

perf cgroup:

  Tommi Rantala:

  - Avoid needless closing of unopened fd

libperf:

  He Zhe:

  - Add NULL pointer check for cpu_map iteration and NULL
    assignment for all_cpus.

  Ian Rogers:

  - Fix a refcount leak in evlist method.

  Arnaldo Carvalho de Melo:

  - Rename the code in tools/perf/util, i.e. perf tooling specific, that
    operates on 'struct evsel' to evsel__, leaving the perf_evsel__
    namespace for the routines in tools/lib/perf/ that operate on
    'struct perf_evsel__'.

tools/perf specific libraries:

  Konstantin Khlebnikov:

  - Fix reading new topology attribute "core_cpus"

  - Simplify checking if SMT is active.

perf flamegraph:

  Arnaldo Carvalho de Melo:

  - Use /bin/bash for report and record scripts, just like all other
    such scripts, fixing a package dependency bug in a Linaro
    OpenEmbedded build checker.

perf evlist:

  Jagadeesh Pagadala:

  - Remove duplicate headers.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Ubuntu 19.10 and debian experimental are failing when linking against
libllvm, which isn't the default, needs to be investigated, haven't
tested with CC=gcc, but should be the same problem:

+ make ARCH= CROSS_COMPILE= EXTRA_CFLAGS= LIBCLANGLLVM=1 -C /git/linux/tools/perf O=/tmp/build/perf CC=clang

  It builds ok with the default set of options.

oops, make that this instead:


commit b3a63d0c17e6e1d23a6b44502b55f066adfd8e6a
Author: Arnaldo Carvalho de Melo <acme@redhat.com>
Date:   Tue May 5 13:33:12 2020 -0300

    perf flamegraph: Use /bin/bash for report and record scripts
    
    As all the other tools/perf/scripts/python/bin/*-{report,record}
    scripts, fixing the this problem reported by Daniel Diaz:
    
      Our OpenEmbedded builds detected an issue with 5287f9269206 ("perf
      script: Add flamegraph.py script"):
        ERROR: perf-1.0-r9 do_package_qa: QA Issue:
      /usr/libexec/perf-core/scripts/python/bin/flamegraph-report contained
      in package perf-python requires /usr/bin/sh, but no providers found in
      RDEPENDS_perf-python? [file-rdeps]
    
      This means that there is a new binary pulled in in the shebang line
      which was unaccounted for: `/usr/bin/sh`. I don't see any other usage
      of /usr/bin/sh in the kernel tree (does not even exist on my Ubuntu
      dev machine) but plenty of /bin/sh. This patch is needed:

Thanks for the reminder, I've just added this to my tree:

commit c74ab13a30d3bec443c116e25b611255c58f32c0
Author: Arnaldo Carvalho de Melo <acme@redhat.com>

    perf flamegraph: Use /bin/bash for report script
    
    As all the other tools/perf/scripts/python/bin/*-report scripts, fixing
    the this problem reported by Daniel Diaz:
    
      Our OpenEmbedded builds detected an issue with 5287f9269206 ("perf

      RDEPENDS_perf-python? [file-rdeps]
    
      This means that there is a new binary pulled in in the shebang line
      which was unaccounted for: `/usr/bin/sh`. I don't see any other usage
      of /usr/bin/sh in the kernel tree (does not even exist on my Ubuntu

Just a gentle reminder that this can still be fixed in today's
linux-next tree (next-20200504).

yeah, the flamegraph scripts are the outliers, there, everything else is
using /bin/bash, so I'll switch to that, ok Andreas?

Our OpenEmbedded builds detected an issue with 5287f9269206 ("perf
script: Add flamegraph.py script"):
  ERROR: perf-1.0-r9 do_package_qa: QA Issue:
/usr/libexec/perf-core/scripts/python/bin/flamegraph-report contained
in package perf-python requires /usr/bin/sh, but no providers found in
RDEPENDS_perf-python? [file-rdeps]

This means that there is a new binary pulled in in the shebang line
which was unaccounted for: `/usr/bin/sh`. I don't see any other usage
of /usr/bin/sh in the kernel tree (does not even exist on my Ubuntu
dev machine) but plenty of /bin/sh. This patch is needed:

  perf hist: Add fast path for duplicate entries check (2020-04-18 09:05:01 -0300)

----------------------------------------------------------------
perf/core fixes and improvements:

kernel + tools/perf:

  Alexey Budankov:

  - Introduce CAP_PERFMON to kernel and user space.

callchains:

  Adrian Hunter:

  - Allow using Intel PT to synthesize callchains for regular events.

  Kan Liang:

  - Stitch LBR records from multiple samples to get deeper backtraces,
    there are caveats, see the csets for details.

perf script:

  Andreas Gerstmayr:

  - Add flamegraph.py script

BPF:

  Jiri Olsa:

  - Synthesize bpf_trampoline/dispatcher ksymbol events.

perf stat:

  Arnaldo Carvalho de Melo:

  - Honour --timeout for forked workloads.

  Stephane Eranian:

  - Force error in fallback on :k events, to avoid counting nothing when
    the user asks for kernel events but is not allowed to.

perf bench:

  Ian Rogers:

  - Add event synthesis benchmark.

tools api fs:

  Stephane Eranian:

 - Make xxx__mountpoint() more scalable

libtraceevent:

  He Zhe:

  - Handle return value of asprintf.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same
problem:

  perf dso: Fix dso comparison (2020-03-24 10:57:38 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf report/top:

  Jin Yao:

  - Support annotation of unresolved symbols, just using its addresses.

  - Print addr_location.al_addr when finding a map but not a symbol, so
    that we have the address relative to the map which is what objdump
    produces, then we can match the output of perf and objdump for such
    unresolved addresses.

  - Allow sorting by non-group leaders when working with multiple events,
    be it in a explicit group, i.e. an event list surrounded by {} (e.g.
    'perf record -e '{cycles,instructions,cache-misses}', or without,
    using --group in 'perf report', e.g.:

        perf record -e cycles,instructions,cache-misses
	perf report --group --group-sort-idx 1

     That '1' will ask for the output to be sorted by 'instructions', not
     the default 'cycles'.

  - Add hotkeys to interactively resort the output when using multiple
    events, '0', '1', ... '9' to resort by the nth event, just like when
    using --group-sort-idx, as explained above.

perf stat:

  Jin Yao:

  - Align the output for interval aggregation mode.

event parsing:

  Ian Rogers:

  - Fix 3 use after frees found with clang ASAN.

perf tools:

  Jiri Olsa:

  - Unify a bit the build directory output.

perf tests:

  John Garry:

  - Add PMU events tests, checking that JSON files are properly parsed.

perf stat:

  Kajol Jain:

  - Fix printing event names of metric group with multiple events incase of overlapping events.

perf symbols:

  Leo Yan:

  - Consolidate symbol fixup issue.

vendor events AMD:

  Vijay Thakkar:

  - Restrict model detection for zen1 based processors

  - Add Zen2 events.

  - Update Zen1 events to V2.

perf cpumap:

  Christophe JAILLET:

 - Fix snprintf overflow check

DSOs:

  Ravi Bangoria:

  - Fix dso comparison wrt IDs (maj, min, etc), that had made 'perf archive'
    stop working when build-ids were not being collected.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same
problem:

+ make ARCH= CROSS_COMPILE= EXTRA_CFLAGS= LIBCLANGLLVM=1 -C /git/linux/tools/perf O=/tmp/build/perf CC=clang

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux and debian:experimental are failing when due to:

  `.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

  perf block-info: Support color ops to print block percents in color (2020-03-09 21:43:25 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf stat:

  Jin Yao:

  - Show percore counts in per CPU output.

perf report:

  Jin Yao:

  - Allow selecting which block info columns to report and its order.

  - Support color ops to print block percents in color.

  - Fix wrong block address comparison in block_info__cmp().

perf annotate:

  Ravi Bangoria:

  - Get rid of annotation->nr_jumps, unused.

expr:

  Jiri Olsa:

  - Move expr lexer to flex.

llvm:

  Arnaldo Carvalho de Melo:

  - Add debug hint message about missing kernel-devel package.

core:

  Kan Liang:

  - Initial patches to support the recently added PERF_SAMPLE_BRANCH_HW_INDEX
    kernel feature.

  - Add check for unexpected use of reserved membrs in event attr, so that in
    the future older perf tools will complain instead of silently try to process
    unknown features.

libapi:

  Namhyung Kim:

  - Adopt cgroupsfs_find_mountpoint() from tools/perf/util/.

libperf:

  Michael Petlan:

  - Add counting example.

libtraceevent:

   Steven Rostedt (VMware):

  - Remove extra '\n' in print_event_time().

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when due to:

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when due to:

  `.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o

OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.

With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:

  bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
  .type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY
               ^

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

+ make ARCH= CROSS_COMPILE= EXTRA_CFLAGS= LIBCLANGLLVM=1 -C /git/linux/tools/perf O=/tmp/build/perf CC=clang

  It builds ok with the default set of options.

  tools lib: Fix builds when glibc contains strlcpy() (2020-01-06 11:46:10 -0300)

----------------------------------------------------------------
perf/core improvements and fixes.

perf record:

  Alexey Budankov:

  - Adapt affinity for machines with #CPUs > 1K to overcome current 1024 CPUs
    mask size limitation of cpu_set_t type.

perf report/top TUI:

  Arnaldo Carvalho de Melo:

  - Make ENTER consistently present the pop up menu with and without call
    chains, to eliminate confusion. The menu continues available at all times
    use 'm' and '+' can be used to toggle just one call chain level, 'e' for all
    the call chains for a top level histogram entry and 'E' to expand all call
    chains in all top level entries. Extra info about these options was added to
    the pop up menu entries. Pressing 'k' serves as special hotkey to go straight
    to the main vmlinux entries, to avoid having to press enter and then select
    "Zoom into the kernel DSO".

perf sched timehist:

  David Ahern:

  - Add support for filtering on CPU.

perf tests:

  Arnaldo Carvalho de Melo:

  - Show expected versus obtained values in bp_signal test.

libperf:

  Jiri Olsa:

  - Move to tools/lib/perf.

  - Add man pages.

libapi:

  Andrey Zhizhikin:

  - Fix gcc9 stringop-truncation compilation error.

tools lib:

  Vitaly Chikunov:

  - Fix builds when glibc contains strlcpy(), which is the case for ALT Linux.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when due to:

  `.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o

OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.

With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:

  bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
  .type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY

  libtraceevent: Copy pkg-config file to output folder when using O= (2019-12-02 21:58:20 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf report/top:

  - Fix segfault due to missing initialization of recently introduced
    struct map_symbol 'maps' field in append_inlines(), when running
    with DWARF callchains.

perf stat:

  Andi Kleen:

  - Affinity based optimizations for sessions with many events in
    machines with large core counts, avoiding excessive number of IPIs.

libtraceevent:

  - Sudip Mukherjee:

  - Fix installation with O=.

  - Copy pkg-config file to output folder when using O=.

perf bench:

  Arnaldo Carvalho de Melo:

  - Update the copies of x86's mem{cpy,set}_64.S, and because that
    now uses new stuff in linux/linkage.h, update that header too, which
    made the minimal clang version to build perf to be 3.5, as
    3.4 as found in some of the container images used to test build perf
    can't grok STT_FUNC as a token in .type lines.

ABI headers:

  Arnaldo Carvalho de Melo:

  - Sync x86's msr-index.h copy with the kernel sources, resulting
    in new MSRs to be usable in filter expressions in 'perf trace',
    such as IA32_TSX_CTRL.

  - Sync linux/fscrypt.h, linux/stat.h, sched.h and the kvm headers.

perf trace:

  Arnaldo Carvalho de Melo:

  - Add CLEAR_SIGHAND support for clone's flags arg

perf kvm:

  Arnaldo Carvalho de Melo:

  - Clarify the 'perf kvm' -i and -o command line options

perf test:

  Ian Rogers:

  - Move test functionality in to a 'perf test' entry.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.

With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:

  bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
  .type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY
               ^

Finally the build-tests and container tests were performed with the following
two fixes (different sha, same contents), that are not in this patch series,
will go thru the bpf/net trees.

The 'perf test' was performed with what is in this series tho.

[GIT PULL] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo/Thomas,

	Please consider pulling, this has a merge with mainline to pick
bpf stuff, and the build-test and container build tests were performed
with two extra patches I cooked to fix libbpf issuers in some odd 32-bit
arches and on generation of some bpf helpers headers that will hit
mainline via the bpf/net trees.

Best regards,

- Arnaldo

Test results at the end of this message, as usual.

The following changes since commit 2ea352d5960ad469f5712cf3e293db97beac4e01:

  Merge remote-tracking branch 'torvalds/master' into perf/core (2019-11-26 11:06:19 -0300)

    architectures.

perf pmu:

  Andi Kleen:

  - Use file system cache to optimize sysfs access.

x86:

  Adrian Hunter:

  - Add some more Intel instructions to the opcode map and to the perf
    test entry:

      gf2p8affineinvqb, gf2p8affineqb, gf2p8mulb, v4fmaddps,
      v4fmaddss, v4fnmaddps, v4fnmaddss, vaesdec, vaesdeclast, vaesenc,
      vaesenclast, vcvtne2ps2bf16, vcvtneps2bf16, vdpbf16ps,

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.

Finally the build-tests and container tests were performed with the following
two fixes, that are not in this patch series, will go thru the bpf/net trees:

  $ git log --oneline -2
  e1bc15a8e7d1 (HEAD -> perf/core) libbpf: Use PRIu64 for sym->st_value to fix build on 32-bit arches
  0d0f9df96c5a libbpf: Fix up generation of bpf_helper_defs.h
  $ 

The 'perf test' was performed with what is in this series tho.

perf/core improvements and fixes:

  - Allow entering the annotation view (symbol source/assembly +
    overhead/cycles/etc column) from the 'perf report --total-cycles'
    interface.

    Then press 'A' or Enter on one of those lines, just like with 'perf top', say
    the top one: [msr.h:105 -> msr.h:166], then this shows up:

    We need to improve this to show the source code line numbers in the
    annotation view, so one can go from that program block to the annotation view
    and see those source code line numbers straight away.

auxtrace/Intel PT:

  Adrian Hunter:

  - Add support for AUX area sampling, requires new functionality that
    will land in 5.5, its already in tip.

    This includes kernel capability querying so that it fails gracefully
    with older kernels, duimping aux area samples in 'perf report -D' and
    'perf script'.

perf.data:

  Alexey Budankov:

  - Fix decompression of PERF_RECORD_COMPRESSED records.

core:

  Arnaldo Carvalho de Melo:

  - Use the 'dcacheline' cmp routine to find the right DSOs taking into
    account the 'maj', 'min', 'ino' and 'ino_generation', that got moved
    from 'struct map' to 'struct dso', where it belongs.

    This further reduces the size of 'struct map', there is still more
    work to do to maybe get it to max one cacheline.

libtraceevent:

  Hewenliang:

  - Fix memory leakage in copy_filter_type().

  Sudip Mukherjee:

  - Fix header installation.

perf parse:

  Ian Rogers :

  - Fix potential memory leak when handling tracepoint errors, found using
    LLVM's libFuzzer.

perf probe:

  Colin Ian King:

  - Fix spelling mistake "addrees" -> "address".

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Manjaro got fixed by adding the 'gettext' package, that provides a
library needed by bison but not present in its dependencies list, i.e. a
distro bug.

cooker is failing with:

Still needs investigating, new image, just leaving it here for
documentation purposes, maybe related to it using the most recent gcc
and clang versions?

[GIT PULL] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo/Thomas,

	Please consider pulling,

Best regards,

- Arnaldo


The following changes since commit e1e9b78d3957a267346a86c8f2c433f6a332af65:

  perf parse: Use YYABORT to clear stack after failure, plugging leaks (2019-11-12 08:34:16 -0300)

are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-5.5-20191119

for you to fetch changes up to a910e4666d61712840c78de33cc7f89de8affa78:

  perf parse: Report initial event parsing error (2019-11-18 19:14:29 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

x86/insn:

  Adrian Hunter:

  - Add some more Intel instructions to the opcode map:

        cldemote, encls, enclu, enclv, enqcmd, enqcmds, movdir64b,
        movdiri, pconfig, tpause, umonitor, umwait, wbnoinvd.

  - The instruction decoding can be tested using the perf tools'
    "x86 instruction decoder - new instructions" test as folllows:

    $ perf test -v "new " 2>&1 | grep -i cldemote
    Decoded ok: 0f 1c 00                    cldemote (%eax)
    Decoded ok: 0f 1c 05 78 56 34 12        cldemote 0x12345678
    Decoded ok: 0f 1c 84 c8 78 56 34 12     cldemote 0x12345678(%eax,%ecx,8)
    Decoded ok: 0f 1c 00                    cldemote (%rax)
    Decoded ok: 41 0f 1c 00                 cldemote (%r8)
    Decoded ok: 0f 1c 04 25 78 56 34 12     cldemote 0x12345678
    Decoded ok: 0f 1c 84 c8 78 56 34 12     cldemote 0x12345678(%rax,%rcx,8)
    Decoded ok: 41 0f 1c 84 c8 78 56 34 12  cldemote 0x12345678(%r8,%rcx,8)
    $ perf test -v "new " 2>&1 | grep -i tpause
    Decoded ok: 66 0f ae f3                 tpause %ebx
    Decoded ok: 66 0f ae f3                 tpause %ebx
    Decoded ok: 66 41 0f ae f0              tpause %r8d

callchains:

  Adrian Hunter:

  - Fix segfault in thread__resolve_callchain_sample().

perf probe:

  - Line fixes to show only lines where probes can be used with 'perf probe -L',
    and when reporting them via 'perf probe -l'.

  - Support multiprobe events.

perf scripts python:

  Adrian Hunter:

  - Fix use of TRUE with SQLite < 3.23 in exported-sql-viewer.py.

perf maps:

  - Trim 'struct map' by removing the rb_node member for sorting
    by map name, as that is only needed for processing kernel maps,
    and only when classifying symbols by section at load time.
    Sort them by name using qsort() and do lookups using bsearch()
    when map_groups__find_by_name() is used.

perf parse:

  Ian Rogers:

  - Report initial event parsing error, providing a less cryptic message
    to state that a PMU wasn't found in the system.

perf vendor events:

  James Clark:

  - Fix commas so that PMU event files for arm64, power8 and power nine
    become valid JSON.

libtraceevent:

  Konstantin Khlebnikov:

  - Fix parsing of event %o and %X argument types.

[GIT PULL] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo/Thomas,

	Please consider pulling,

Best regards,

Test results at the end of this message, as usual.

The following changes since commit 56b2147f34d057b0898c53a3eb2e9e70756ab89f:

  Merge tag 'perf-core-for-mingo-5.5-20191107' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2019-11-12 12:06:08 +0100)

  perf parse: Use YYABORT to clear stack after failure, plugging leaks (2019-11-12 08:34:16 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf record:

  Ravi Bangoria:

  - Provide an option to print perf_event_open args and syscall return value.
    This was already possible using -v, but then lots of other debug info
    would be output as well, provide a way to show just the syscall args
    and return value, e.g.:

      # perf --debug perf-event-open=1 record
      perf_event_attr:
        size                             112
        { sample_period, sample_freq }   4000
        sample_type                      IP|TID|TIME|PERIOD
        read_format                      ID
        disabled                         1
        inherit                          1
      <SNIP>
        ksymbol                          1
        bpf_event                        1
      ------------------------------------------------------------
      sys_perf_event_open: pid 4308  cpu 0  group_fd -1  flags 0x8 = 4

core:

- Remove map->groups, we can get that information in other ways, reduces
  the size of a key data structure and paves the way to have it shared
  by multiple threads.

- Use 'struct map_symbol' in more places, where we already were using a
  'struct map' + 'struct symbol', this helps passing that usual pair of
  information across callchain, browser code, etc.

- Add 'struct map_groups' (where the map_symbol->map is) to 'struct map_symbol',
  to ease annotation code, for instance, where we call from functions in one map
  we're browsing to functions in another DSO, mapped in another 'struct map'.

event parsing:

  Ian Rogers:

  - Use YYABORT to clear stack after failure, plugging leaks

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Manjaro is failing due to some missing library related to bison, looks like
a distro bug.

----------------------------------------------------------------
perf/core improvements and fixes:

perf report:

  Jin Yao:

  - Introduce --total-cycles, for basic block profiling, further using data
    obtained from LBR, an example should suffice:

      # perf record -b
      ^C[ perf record: Woken up 595 times to write data ]
      [ perf record: Captured and wrote 156.672 MB perf.data (196873 samples) ]

      # perf report --total-cycles --stdio
      # To display the perf.data header info, please use --header/--header-only options.

perf record:

  Adrian Hunter:

  - Allow storing perf.data in a directory together with a copy of /proc/kcore.

  Jiwei Sun:

  - Add support for limit perf output file size, i.e.:

    # perf record --all-cpus -F 10000 --max-size=4M sleep 10h
    [ perf record: perf size limit reached (4097 KB), stopping session ]
    [ perf record: Woken up 6 times to write data ]
    [ perf record: Captured and wrote 4.048 MB perf.data (54094 samples) ]
    Terminated
    # ls -lah perf.data
    -rw-------. 1 root root 4.1M Nov  7 15:27 perf.data
    #

perf stat:

  Jiri Olsa:

  - Add --per-node agregation support:

    In live mode:

      # perf stat  -a -I 1000 -e cycles --per-node
      #           time node   cpus             counts unit events

  - Fix to show function entry line as probe-able

  - Fix wrong address verification

  - Fix to probe a function which has no entry pc

  - Fix to probe an inline function which has no entry pc

  - Fix to list probe event with correct line number

  - Fix to show inlined function callsite without entry_pc

  - Fix to show ranges of variables in functions without entry_pc

  - Return a better scope DIE if there is no best scope

  - Skip end-of-sequence and non statement lines

  - Filter out instances except for inlined subroutine and subprogram

  - Fix to show calling lines of inlined functions

  - Skip overlapped location on searching variables

perf inject:

  Adrian Hunter:

  - Do not strip evsels with --strip, as they are needed for create_gcov
    (see the autofdo example in tools/perf/Documentation/intel-pt.txt).

Intel PT:

  Adrian Hunter:

  - Intel PT uses an auxtrace_cache to store the results of code-walking, to avoid
    repeated decoding. Add an auxtrace_cache__remove to handle text poke events.

core:

  Andi Kleen:

  - Always preserve errno while cleaning up perf_event_open failures.

llvm:

  Arnaldo Carvalho de Melo:

  - No need to tell that the request for saving a .o file for BPF events, as
    expressed in ~/.perfconfig was satisfied, make that a debug message.

perf vendor events:

Intel:

  Haiyan Song:

  - Update CascadelakeX events to v1.05.

  - Update all the Intel JSON metrics from TMAM 3.6.

Treewide:

  Ian Rogers:

  - Improve error paths, plugging leaks found using LLVM tools
    such as libFuzzer.

jevents:

  Yunfeng Ye:

  - Fix resource leak in process_mapfile() and main()

perf kvm:

  Igor Lubashev:

  - Use evlist layer api when possible.

libsubcmd:

  James Clark:

  - Move EXTRA_FLAGS to the end to allow overriding existing flags.

  - Use -O0 with DEBUG=1

perf diff:

  Jin Yao:

  - Don't use hack to skip column length calculation

CoreSight ETM:

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Manjaro is failing due to some missing library related to bison, looks like
a distro bug.

  perf trace: Use STUL_STRARRAY_FLAGS with mmap (2019-10-19 15:35:02 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf trace:

- Add syscall failure stats to -s/--summary and -S/--with-summary, also works in
  combination with specifying just a set of syscalls, see below first with
  -s/--summary, then with -S/--with-summary just for the syscalls we saw failing
  with -s:

    # perf trace -s sleep 1

    #

  - Add a generator for x86's IRQ vectors -> strings

  - Introduce stroul() (string -> number) methods for the strarray and
    strarrays classes, also strtoul_flags, allowing to go from both strings
    and or-ed strings to numbers, allowing things like:

    # perf trace -e syscalls:sys_enter_mmap --filter="flags==DENYWRITE|PRIVATE|FIXED" sleep 1
         0.000 sleep/22588 syscalls:sys_enter_mmap(addr: 0x7f42d2aa5000, len: 1363968, prot: READ|EXEC, flags: PRIVATE|FIXED|DENYWRITE, fd: 3, off: 0x22000)

    #

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

----------------------------------------------------------------
perf/core improvements and fixes:

perf trace:

  Arnaldo Carvalho de Melo:

  - Reuse the strace-like syscall_arg_fmt->scnprintf() beautification routines
    (convert integer arguments into strings, like open flags, etc) in tracepoint
    arguments.

    For now the type based scnprintf routines (pid_t, umode_t, etc) and the
    ones based in well known arg name based ("fd", etc) gets associated with
    tracepoint args of that type.

    A tracepoint only arg, "msr", for the msr:{write,read}_msr gets added as
    an initial step.

  - Introduce syscall_arg_fmt->strtoul() methods to be the reverse operation
    of ->scnprintf(), i.e. to go from a string to an integer.

  - Implement --filter, just like in 'perf record', that affects the tracepoint
    events specied thus far in the command line, use the ->strtoul() methods
    to allow strings in tables associated with beautifiers to the integers
    the in-kernel tracepoint (eBPF later) filters expect, e.g.:

     # perf trace --max-events 1 -e sched:*ipi --filter="cpu==1 || cpu==2"
      0.000 as/24630 sched:sched_wake_idle_without_ipi(cpu: 1)

  - Default to not using libtraceevent and its plugins for beautifying
    tracepoint arguments, since now we're reusing the strace-like beautifiers.
    Use --libtraceevent_print (using just --libtrace is unambiguous and can
    be used as a short hand) to go back to those beautifiers.

    This will help in the transition, as can be seen in some of the sched tracepoints
    that still need some work in the libbeauty based mode:

  - Make -v (verbose) mode be honoured for .perfconfig based trace.add_events,
    to help in diagnosing problems with building eBPF events (-e source.c).

  - When using eBPF syscall payload augmentation do not show strace-like
    syscalls when all the user specified was some tracepoint event, bringing
    the behaviour in line with that of when not using eBPF augmentation.

Intel PT:

  exported-sql-viewer GUI:

  Adrian Hunter:

  - Add LookupModel, HBoxLayout, VBoxLayout, global time range calculations
    so as to add a time chart by CPU.

perf script:

  Andi Kleen:

  - Allow --time (to specify a time span of interest) with --reltime

perf diff:

  Jin Yao:

  - Report noise for cycles diff, i.e. a histogram + stddev.
    (timestamps relative to start).

perf annotate:

  Arnaldo Carvalho de Melo:

  - Initialize env->cpuid when running in live mode (perf top), as it
    is used in some of the per arch annotation init routines.

samples bpf:

  Björn Töpel:

  - Fixup fallout of using tools/perf/perf-sys. from outside tools/perf.

Core:

  Ian Rogers:

  - Avoid 'sample_reg_masks' being const + weak, as this breaks with some
    compilers that constant-propagate from the weak symbol.

libperf:

  - First part of moving the perf_mmap class from tools/perf to libperf.

  - Propagate CFLAGS to libperf from the tools/perf Makefile.

Vendor events:

  John Garry:

  - Add entry in MAINTAINERS with reviewers for the for perf tool arm64
    pmu-events files.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

>   perf parser: Remove needless include directives (2019-09-25 16:26:41 -0300)
> 
> ----------------------------------------------------------------
> perf/core improvements and fixes:
> 
> perf record:
> 
>   Stephane Eranian:
> 
>   - Fix priv level with branch sampling for paranoid=2, i.e. the kernel checks
>     if perf_event_attr_attr.exclude_hv is set in addition to .exclude_kernel,
>     so reset both to zero.
> 
>   Arnaldo Carvalho de Melo:
> 
>   - Don't warn about not being able to read kernel maps (kallsyms, etc) when
>     kernel samples aren't being collected.
> 
> perf list:
> 
>   Kim Phillips:
> 
>   - Allow plurals for metric, metricgroup., i.e.:
> 
>     $ perf list metrics
> 
>     was showing nothing, which is very confusing, make it work like:
> 
>     $ perf stat metric
> 
> perf stat:
> 
>   Andi Kleen:
> 
>   - Free memory access/leaks detected via valgrind, related to metrics.
> 
> Libraries:
> 
> libperf:
> 
>   Jiri Olsa:
> 
>   - Move more stuff from tools/perf, this time a first stab at moving perf_mmap
>     methods.
> 
> libtracevent:
> 
>   Steven Rostedt (VMware):
> 
>   - Round up in tep_print_event() time precision.
> 
>   Tzvetomir Stoyanov (VMware):
> 
>   - Man pages for event print and related and plugins APIs.
> 
>   - Move traceevent plugins in its own subdirectory.
> 
> Feature detection:
> 
>   Thomas Richter:
> 
>   - Add detection of java-11-openjdk-devel package, in addition to the older
>     versions supported.
> 
> Architecture specific:
> 
> S/390:
> 
>   Thomas Richter (2):
> 
>   - Include JVMTI support for s390
> 
> Vendor events:
> 
> AMD:
> 
>   Kim Phillips:
> 
>   - Add L3 cache events for Family 17h.
> 
>   - Remove redundant '['.
> 
> PowerPC:
> 
>   Mamatha Inamdar:
> 
>   - Remove P8 HW events which are not supported.
> 
> Cleanups:
> 
>   Arnaldo Carvalho de Melo:
> 
>   - Remove needless headers, add needed ones, move things around to reduce the
>     headers dependency tree, speeding up builds by not doing needless compiles
>     when unrelated stuff gets changed.
> 
>   - Ditch unused code that was dragging headers.

  perf parser: Remove needless include directives (2019-09-25 16:26:41 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf record:

  Stephane Eranian:

  - Fix priv level with branch sampling for paranoid=2, i.e. the kernel checks
    if perf_event_attr_attr.exclude_hv is set in addition to .exclude_kernel,
    so reset both to zero.

  Arnaldo Carvalho de Melo:

  - Don't warn about not being able to read kernel maps (kallsyms, etc) when
    kernel samples aren't being collected.

perf list:

  Kim Phillips:

  - Allow plurals for metric, metricgroup., i.e.:

    $ perf list metrics

    was showing nothing, which is very confusing, make it work like:

    $ perf stat metric

perf stat:

  Andi Kleen:

  - Free memory access/leaks detected via valgrind, related to metrics.

Libraries:

libperf:

  Jiri Olsa:

  - Move more stuff from tools/perf, this time a first stab at moving perf_mmap
    methods.

libtracevent:

  Steven Rostedt (VMware):

  - Round up in tep_print_event() time precision.

  Tzvetomir Stoyanov (VMware):

  - Man pages for event print and related and plugins APIs.

  - Move traceevent plugins in its own subdirectory.

Feature detection:

  Thomas Richter:

  - Add detection of java-11-openjdk-devel package, in addition to the older
    versions supported.

Architecture specific:

S/390:

  Thomas Richter (2):

  - Include JVMTI support for s390

Vendor events:

AMD:

  Kim Phillips:

  - Add L3 cache events for Family 17h.

  - Remove redundant '['.

PowerPC:

  Mamatha Inamdar:

  - Remove P8 HW events which are not supported.

Cleanups:

  Arnaldo Carvalho de Melo:

  - Remove needless headers, add needed ones, move things around to reduce the
    headers dependency tree, speeding up builds by not doing needless compiles
    when unrelated stuff gets changed.

  - Ditch unused code that was dragging headers.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

[GIT PULL] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo/Thomas,

	Please consider pulling,

Best regards,

- Arnaldo

Test results at the end of this message, as usual.

The following changes since commit 42880f726c66f13ae1d9ac9ce4c43abe64ecac84:

  perf/x86/intel: Support PEBS output to PT (2019-08-28 11:29:39 +0200)

are available in the Git repository at:

for you to fetch changes up to 301011ba622513cb41ced59973972204e0da2f71:

  tools lib traceevent: Remove unneeded qsort and uses memmove instead (2019-08-29 08:36:12 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf top:

  Namhyung Kim:

  - Decay all events in the evlist, we were decaying just the first event
    in a group.

  - Fix linking of histograms in different evsels in a event group with more
    than two events.

  With the two fixes above a command line such as:

    # perf top -e '{cycles,instructions,cache-misses,cache-references}

    Should work as expected, with four columns and with all of them being
    decayed over time, i.e. less weight is given for older samples.

perf record:

  Arnaldo Carvalho de Melo:

  - Fix collection of build-ids when using setns() to get into namespaces,
    which had been broken with the introduction of the extra thread to
    react to PERF_RECORD_BPF_EVENT, i.e. to collect extra info for BPF
    programs. We need to unshare(CLONE_FS) in that thread so that the
    main one can do the setns(CLONE_NEWNS) when collectingthe build-ids.
    Without that symbol resolution gets more difficult and potentially
    misresolves symbols.

core:

  Igor Lubashev:

  - Further alignment in permission checking via capabilities to how the
    kernel checks what tooling tries to do.

PowerPC:

  Naveen N. Rao:

  - Sync powerpc syscall.tbl, so that 'perf trace' gets the definitions
    for recent syscalls.

libperf:

  Jiri Olsa:

  - Move the rest of the PERF_RECORD_ metadata struct definitions so that
    we can use 'union perf_event'.

libtraceevent:

  Steven Rostedt (VMware):

  - Do not free tep->cmdlines in add_new_comm() on failure.

  - Remove unneeded qsort and uses memmove instead

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

  libperf: Fix alignment trap with xyarray contents in 'perf stat' (2019-08-22 17:16:57 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf c2c:

  Ravi Bangoria:

  - Fix report with offline cpus.

libperf:

  Gerald BAEZA:

  - Fix alignment trap with xyarray contents in 'perf stat', noticed on ARMv7.

  Jiri Olsa:

  - Move some more cpu_map and thread_map methods from tools/perf/util/ to libperf.

headers:

  Arnaldo Carvalho de Melo:

  - Do some house cleaning on the headers, removing needless includes in some places,
    providing forward declarations when those are the only thing needed, and fixing
    up the fallout from that for cases where we were using stuff and not adding the
    necessary headers. Should speed up the build and avoid needless rebuilds when
    something unrelated gets touched.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Yeah, we need to polish these kind of little details, pressing 'C' and
getting callchains enabled/disabled would be nice as well in 'perf top',
just thought about that :-)

  libperf: Fix arch include paths (2019-08-20 12:29:36 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

callchains:

   Alexey Budankov:

  - Allow collecting LBR together with DWARF callchains, for workloads
    where the userspace stack size collected is not big enough for
    pure DWARF based unwinding.

  - Dump the LBR call stack in 'perf report -D'.

perf top:

  Arnaldo Carvalho de Melo:

  - Show visual cue at start to state that the minimal set of samples
    are being collected prior to sorting/bucketizing/displaying.

CoreSight (ARM hardware tracing):

  Leo Yan:

  - Support sample flags 'insn' and 'insnlen'.

core:

  Adrian Hunter:

  - Add comment for 'idx' member in 'struct perf_sample_id.

tools headers:

  Arnaldo Carvalho de Melo:

  - Synchronize linux/bits.h, which required grabbing a copy of the kernel
    const.h headers and some changes in the ordering of header directories.

  - Sync x86's asm/cpufeatures.h with the with the kernel, no change in
    any of the tools.

libperf:

  Jiri Olsa:

  - Fix arch include paths.

libtraceevent:

  Steven Rostedt (VMware):

  - Fix "robust" test of do_generate_dynamic_list_file.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

  perf unwind: Remove unnecessary test (2019-08-16 12:30:14 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

report/script/trace/top:

  Arnaldo Carvalho de Melo:

  - Allow specifying marker events demarcating when to consider the other events,
    i.e. one now can state something like:

        # perf probe kernel_function
        # perf record -e cycles,probe:kernel_function

    And then, in 'perf script' or 'perf report' say:

        # perf report --switch-on=probe:kernel_function

    And then the cycles event samples will be considered only after we
    find the first probe:kernel_function event.

    There is also --switch-off=event, to make it stop considering events
    out of some window, say to avoid some winding down of a workload.

    The same can be done with the "live mode" tools: 'perf top' and 'perf trace'.

    There are examples in the cset comments showing how to use it with
    SDT events in things like 'systemtap', that have those tracepoint-like
    events for the start/end of passes, etc.

    Another example involves selecting scheduler events + entry/exit of
    a syscall, using the syscalls tracepoints, one can then see the
    scheduler events that take place while that syscall is being processed.

    In the future this should be possible in record/top/trace via eBPF
    where the perf tools would hook into the marker events and enable events
    put in place but not enabled when the on/off conditions are the desired
    ones, reducing the amount of events sampled, but this userspace only
    solution should be good enough for many scenarios.

perf vendor events intel:

  Haiyan Song:

  - Add Tremontx event file v1.02.

unwind:

  John Keeping:

  - Fix callchain unwinding when tid != pid, that was working only for the
    thread group leader.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

  perf ui: No need to set ui_browser to 1 twice (2019-08-14 11:00:00 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

Intel PT:

  Adrian Hunter:

  - Add PEBS via Intel PT support, the kernel bits went via PeterZ.

perf record:

  Alexander Shishkin:

  - Add an option to take an AUX snapshot on exit.

  Tan Xiaojun:

  - Support aarch64 random socket_id assignment, just like was fixed for S/390.

tools:

  Andy Shevchenko:

  - Keep list of tools in alphabetical order on 'make -C tools help'.

perf session:

  Arnaldo Carvalho de Melo:

  - Avoid infinite loop when seeing invalid header.size, reported by
    Vince Weaver using a perf.data fuzzer.

Documentation:

  Vince Weaver:

  - Clarify HEADER_SAMPLE_TOPOLOGY format in the perf.data spec.

perf config:

  Arnaldo Carvalho de Melo:

  - Honour $PERF_CONFIG env var to specify alternate .perfconfig.

perf test:

  Arnaldo Carvalho de Melo:

  - Disable ~/.perfconfig to get default output in 'perf trace' tests.

perf top:

  Arnaldo Carvalho de Melo:

  - Set display thread COMM to help with debugging.

  - Collapse and resort evsels in a group, so that we have output
    similar to 'perf report' when using event groups, i.e.

      perf top -e '{cycles,instructions}'

    Will have two columns, and the instructions one will work.

core:

  Igor Lubashev:

  - Detect if libcap development files are available so that we
    can use capabilities to match the checks made by the kernel instead
    of using plain (geteuid() == 0).

Intel:

  Haiyan Song:

  - Add Icelake V1.00 event file.

perf trace:

  Leo Yan:

  - Fix segmentation fault when access syscall info on arm64.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

	Please consider pulling,

Best regards,

- Arnaldo

Test results at the end of this message, as usual.

The following changes since commit 323fd749821daab0f327ec86d707c4542963cdb0:

  perf intel-pt: Fix potential NULL pointer dereference found by the smatch tool (2019-07-09 10:13:28 -0300)

are available in the Git repository at:

for you to fetch changes up to 916c31fff946fae0e05862f9b2435fdb29fd5090:

  perf version: Fix segfault due to missing OPT_END() (2019-07-15 07:59:05 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf db-export:

  Adrian Hunter:

  - Improvements in how COMM details are exported to databases for
    post processing and use in the sql-viewer.py UI.

  - Export switch events to the database.

BPF:

  Arnaldo Carvalho de Melo:

  - Bump rlimit(MEMLOCK) for 'perf test bpf' and 'perf trace', just like
    selftests/bpf/bpf_rlimit.h do, which makes errors due to exhaustion of
    this limit, which are kinda cryptic (EPERM sometimes) less frequent.

perf version:
  Ravi Bangoria:

  - Fix segfault due to missing OPT_END(), noticed on PowerPC.

perf vendor events:

  Thomas Richter:

  - Add JSON files for IBM s/390 machine type 8561.

perf cs-etm (ARM):

  YueHaibing:

  - Fix two cases of error returns not bing done properly: Invalid ERR_PTR() use
    and loss of propagation error codes.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

The 'perf test bpf' test is about rlimit(MEMLOCK), bump it a to 128K from the
default 64K and it'll work. Next pull req will have auto-adjustment for 'perf
test' and 'perf trace', where BPF programs creating maps are also failing.

  perf intel-pt: Fix potential NULL pointer dereference found by the smatch tool (2019-07-09 10:13:28 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

Intel PT:

  Adrian Hunter:

  - Fix DROP VIEW power_events_view in the postgresql and sqlite export-db
    python scripts.

perf script:

  Song Liu:

  - Assume native_arch for pipe mode, fixing a segfault.

perf inject:

  Arnaldo Carvalho de Melo:

  - The tool->read() call may pass a NULL evsel, handle it.

core:

  Arnaldo Carvalho de Melo:

  - Move zalloc/zfree.c to tools/lib, further eroding tools/perf/util.[ch]

  - Use zfree() where applicable instead of open coded equivalent.

  - Add stdlib.h and some other headers to places where its needed and were
    getting via util.h, that doesn't need that anymore.

  - Use list_del_init() more thoroughly.

Miscellaneous:

  Leo Yan:

  - Fix use after free and potential NULL pointer derefs detected by the
    smatch tool in various places.

  Luke Mujica:

  - Remove a couple unused variables in the parse-events code.

  Numfor Mbiziwo-Tiapo:

  - Initialize variable to suppress memory sanitizer warning in the
    mmap-thread-lookup 'perf test' entry.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

The 'perf test bpf' test is about rlimit(MEMLOCK), bump it a to 128K from the
default 64K and it'll work. Next pull req will have auto-adjustment for 'perf
test' and 'perf trace', where BPF programs creating maps are also failing.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Investigating the failure for ubuntu:18.04-x-arm, doesn't look like something
introduced by this patchkit.

ubuntu:18.04-x-arm failure not yet resolved, doesn't seem related to
this patchkit nor the previous one.

  - Find routines in tools/perf/util/ that have implementations in the kernel
    libraries (lib/*.c), such as strreplace(), strim(), skip_spaces() and reuse
    them after making a copy into tools/lib and tools/include/.

    This continues the effort of having tools/ code looking as much as possible
    like kernel source code, to help encourage people to work on both the kernel
    and in tools hosted in the kernel sources.

    That in turn will help moving stuff that uses those routines to
    tools/lib/perf/ where they will be made available for use in other tools.

    In the process ditch old cruft, remove unused variables and add missing
    include directives for headers providing things used in places that were
    building by sheer luck.

  - Bump MAX_NR_CPUS and MAX_CACHES to get these tools to work on more machines.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Investigating the failure for ubuntu:18.04-x-arm, doesn't look like something
introduced by this patchkit.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

  perf trace: Skip unknown syscalls when expanding strace like syscall groups (2019-06-10 17:50:04 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf record:

  Alexey Budankov:

  - Allow mixing --user-regs with --call-graph=dwarf, making sure that
    the minimal set of registers for DWARF unwinding is present in the
    set of user registers requested to be present in each sample, while
    warning the user that this may make callchains unreliable if more
    that the minimal set of registers is needed to unwind.

  yuzhoujian:

  - Add support to collect callchains from kernel or user space only,
    IOW allow setting the perf_event_attr.exclude_callchain_{kernel,user}
    bits from the command line.

perf trace:

  Arnaldo Carvalho de Melo:

  - Remove x86_64 specific syscall numbers from the augmented_raw_syscalls
    BPF in-kernel collector of augmented raw_syscalls:sys_{enter,exit}
    payloads, use instead the syscall numbers obtainer either by the
    arch specific syscalltbl generators or from audit-libs.

  - Allow 'perf trace' to ask for the number of bytes to collect for
    string arguments, for now ask for PATH_MAX, i.e. the whole
    pathnames, which ends up being just a way to speficy which syscall
    args are pathnames and thus should be read using bpf_probe_read_str().

  - Skip unknown syscalls when expanding strace like syscall groups.
    This helps using the 'string' group of syscalls to work in arm64,
    where some of the syscalls present in x86_64 that deal with
    strings, for instance 'access', are deprecated and this should not
    be asked for tracing.

  Leo Yan:

  - Exit when failing to build eBPF program.

perf config:

  Arnaldo Carvalho de Melo:

  - Bail out when a handler returns failure for a key-value pair. This
    helps with cases where processing a key-value pair is not just a
    matter of setting some tool specific knob, involving, for instance
    building a BPF program to then attach to the list of events 'perf
    trace' will use, e.g. augmented_raw_syscalls.c.

perf.data:

  Kan Liang:

  - Read and store die ID information available in new Intel processors
    in CPUID.1F in the CPU topology written in the perf.data header.

perf stat:

  Kan Liang:

  - Support per-die aggregation.

Documentation:

  Arnaldo Carvalho de Melo:

  - Update perf.data documentation about the CPU_TOPOLOGY, MEM_TOPOLOGY,
    CLOCKID and DIR_FORMAT headers.

  Song Liu:

  - Add description of headers HEADER_BPF_PROG_INFO and HEADER_BPF_BTF.

  Leo Yan:

  - Update default value for llvm.clang-bpf-cmd-template in 'man perf-config'.

JVMTI:

  Jiri Olsa:

  - Address gcc string overflow warning for strncpy()

core:

  - Remove superfluous nthreads system_wide setup in perf_evsel__alloc_fd().

Intel PT:

  Adrian Hunter:

  - Add support for samples to contain IPC ratio, collecting cycles
    information from CYC packets, showing the IPC info periodically, because
    Intel PT does not update the cycle count on every branch or instruction,
    the incremental values will often be zero.  When there are values, they
    will be the number of instructions and number of cycles since the last
    update, and thus represent the average IPC since the last IPC value.

    E.g.:

    # perf record --cpu 1 -m200000 -a -e intel_pt/cyc/u sleep 0.0001
    rounding mmap pages size to 1024M (262144 pages)
    [ perf record: Woken up 0 times to write data ]
    [ perf record: Captured and wrote 2.208 MB perf.data ]
    # perf script --insn-trace --xed -F+ipc,-dso,-cpu,-tid
    #
    <SNIP + add line numbering to make sense of IPC counts e.g.: (18/3)>

  - Allow using time ranges with Intel PT, i.e. these features, already
    present but not optimially usable with Intel PT, should be now:

        Select the second 10% time slice:

        $ perf script --time 10%/2

        Select from 0% to 10% time slice:

        $ perf script --time 0%-10%

        Select the first and second 10% time slices:

        $ perf script --time 10%/1,10%/2

        Select from 0% to 10% and 30% to 40% slices:

        $ perf script --time 0%-10%,30%-40%

cs-etm (ARM):

  Mathieu Poirier:

  - Add support for CPU-wide trace scenarios.

s390:

  Thomas Richter:

  - Fix missing kvm module load for s390.

  - Fix OOM error in TUI mode on s390

  - Support s390 diag event display when doing analysis on !s390
    architectures.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

[GIT PULL] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, I pulled tip/perf/urgent into
tip/pref/core, IIRC was just a fast forward at that point, yeap, just
did it again and it still is:

  $ git checkout -b t tip/perf/core
  Branch 't' set up to track remote branch 'perf/core' from 'tip'.
  Switched to a new branch 't'
  $ git merge tip/perf/urgent
  Updating d15d356887e7..c7a286577d75
  Fast-forward
  <SNIP>

         IIRC Jiri needs this for a pile of patches he submitted and
that I'll process next,

Best regards,

- Arnaldo

  perf stat: Support 'percore' event qualifier (2019-05-16 14:17:24 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf.data:

  Alexey Budankov:

  - Streaming compression of perf ring buffer into PERF_RECORD_COMPRESSED
    user space records, resulting in ~3-5x perf.data file size reduction
    on variety of tested workloads what saves storage space on larger
    server systems where perf.data size can easily reach several tens or
    even hundreds of GiBs, especially when profiling with DWARF-based
    stacks and tracing of context switches.

perf record:

  Arnaldo Carvalho de Melo

  - Improve -user-regs/intr-regs suggestions to overcome errors.

perf annotate:

  Jin Yao:

  - Remove hist__account_cycles() from callback, speeding up branch processing
    (perf record -b).

perf stat:

  - Add a 'percore' event qualifier, e.g.: -e cpu/event=0,umask=0x3,percore=1/,
    that sums up the event counts for both hardware threads in a core.

    We can already do this with --per-core, but it's often useful to do
    this together with other metrics that are collected per hardware thread.

    I.e. now its possible to do this per-event, and have it mixed with other
    events not aggregated by core.

core libraries:

  Donald Yandt:

  - Check for errors when doing fgets(/proc/version).

  Jiri Olsa:

  - Speed up report for perf compiled with linbunwind.

tools headers:

  Arnaldo Carvalho de Melo

  - Update memcpy_64.S, x86's kvm.h and pt_regs.h.

arm64:

  Florian Fainelli:

  - Map Brahma-B53 CPUID to cortex-a53 events.

  - Add Cortex-A57 and Cortex-A72 events.

csky:

  Mao Han:

  - Add DWARF register mappings for libdw, allowing --call-graph=dwarf to work
    on the C-SKY arch.

x86:

  Andi Kleen/Kan Liang:

  - Add support for recording and printing XMM registers, available, for
    instance, on Icelake.

  Kan Liang:

  - Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON support.
    UPI replaced the Intel QuickPath Interconnect (QPI) in Xeon Skylake-SP.

Intel PT:

  Adrian Hunter

  . Fix instructions sampling rate.

  . Timestamp fixes.

  . Improve exported-sql-viewer GUI, allowing, for instance, to copy'n'paste
    the trees, useful for e-mailing.

Documentation:

  Thomas Richter:

  - Add description for 'perf --debug stderr=1', which redirects stderr to stdout.

libtraceevent:

  Tzvetomir Stoyanov:

  - Add man pages for the various APIs.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
