This updates includes data structure accessing support --list option enhancement and --dry-run option support. - --dry-run allows users to run perf-probe just for checking that the command works correctly. - --list option enhancement allows user to check where the probes are put on (with filename/line number). - data structure accessing support allows user to trace the contents of local variables/function parameters. Long-term TODOs (future features): - Enhance probe-finder to decode call frame instructions. - Support tracing static variables (non global) - Support variable basic types from debuginfo (e.g. char, int, ...) - Support array element (var[N]) - Support string/dynamic arrays (*var, var[N..M]) - Support the type of return value - Support force type-casting ((type)var) - Support sys_perf_counter_open (for non-root users) - Support dynamic array-indexing (var[var2]) Miscs: - Better support for probes on modules - More debugger like enhancements(%next, --disasm, etc.) Thank you, --- Masami Hiramatsu (10): perf probe: Accessing members in data structures perf probe: List probes with line number and file name perf probe: Introduce kprobe_trace_event and perf_probe_event perf probe: Add --dry-run option perf probe: Introduce die_find_child() function perf probe: Rename some die_get_* functions perf probe: Rename session to param perf probe: Move add-probe routine under util/ perf probe: Use wrapper functions perf tools: Introduce xzalloc() for detecting out of memory tools/perf/Documentation/perf-probe.txt | 5 tools/perf/builtin-probe.c | 191 +------ tools/perf/util/probe-event.c | 830 +++++++++++++++++++++++-------- tools/perf/util/probe-event.h | 123 ++++- tools/perf/util/probe-finder.c | 459 ++++++++++++----- tools/perf/util/probe-finder.h | 60 +- tools/perf/util/util.h | 7 7 files changed, 1115 insertions(+), 560 deletions(-) -- Masami Hiramatsu e-mail: mhiramat@redhat.com
