Subject: [GIT PULL 00/31] perf tools: filtering events using eBPF programs
Date: Sat, 29 Aug 2015 04:21:34 +0000 [thread overview]
Message-ID: <1440822125-52691-1-git-send-email-wangnan0@huawei.com> (raw)
Hi Arnaldo and Ingo,
Several small proglems are fixed based on yesterday's pull request. Please
see below. Since patch order is changed (original 20/32 and 32/32 are
dropped), I decide to send all of them again. Sorry for the noisy.
In addition: I collect a cross-compiling fix I posted yesterday into this
cset (the last one).
The following changes since commit 2c07144dfce366e21465cc7b0ada9f0b6dc7b7ed:
perf evlist: Add backpointer for perf_env to evlist (2015-08-28 14:54:14 -0300)
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/pi3orama/linux tags/perf-ebpf-for-acme-20150829
for you to fetch changes up to d4a337392b3724899a084170d9ea36a8e2392097:
tools lib traceevent: Support function __get_dynamic_array_len (2015-08-29 02:57:40 +0000)
----------------------------------------------------------------
perf BPF related improvements and bugfix:
- Rebase to Arnaldo's newest perf/core.
- Fix a missing include in builtin-trace.c.
- Drop patch 'perf tools: Fix probe-event.h include' since
the problem has been fixed by commit 5a023b57.
- Fix a cross compiling error (introduced by inter pt).
- Drop patch 'bpf: Introduce function for outputing data to
perf event' because we want to do better.
