- Subject: [PATCH -tip perf/probes 00/10] x86 insn decoder bugfixes
Hi Ingo,
Here are bugfixes and some enhances of x86-insn decoder and perf-probe.
- x86 insn decoder supports AVX and FMA.
- perf-probe syntax change.
- perf-probe supports function-relative line number.
- minor bugfixes.
New perf-probe syntax is below:
perf probe 'PROBE'
or
perf probe --add 'PROBE'
where, PROBE is
<source>:<line-number>
or
<function>[:<rel-lineno>|+<byte-offset>|%return][@<source>]
e.g.
perf probe 'schedule:10@kernel/sched.c'
puts a probe at 10th line from entry line of schedule() function
in kernel/sched.c." and
perf probe 'vmalloc%return'
puts a return probe at the returning of vmalloc.
TODO:
- Support --line option to show which lines user can probe.
- Support lazy string matching.
Thank you,
