perf tools: Add Intel PT instruction decoder

2015-08-17T14:11:36Z

Add support for decoding instructions for Intel Processor Trace. The kernel x86 instruction decoder is copied for this. This essentially provides intel_pt_get_insn() which takes a binary buffer, uses the kernel's x86 instruction decoder to get details of the instruction and then categorizes it for consumption by an Intel PT decoder.

perf build: Use FEATURE-DUMP instead of PERF-FEATURES in the .gitignore file

2015-03-20T20:49:51Z

Since commit 4ae61202b31c ("perf build: Rename PERF-FEATURES into FEATURE-DUMP") renames PERF-FEATURES into FEATURE-DUMP, the .gitignore file should also do this thing for consistency.

perf tools: Add perf-with-kcore script

2014-09-17T20:08:08Z

Decoding an Intel PT trace of the kernel requires an accurate kernel object image. This is provided by making a copy of kcore. However the copy needs to be made under the same conditions as the original recording, and then it needs to be associated with the perf.data file. The perf-with-kcore script does that. The script also checks the permissions on the buildid cache and can be used to fix them. That is needed for distributions where root does not have a home directory and consequently writes to the same buildid cache as the user, resulting in cached files that the user does not have access to. Example: $ ./perf-with-kcore Usage: perf-with-kcore [ [ -- ]] can be record, script, report or inject or: perf-with-kcore fix_buildid_cache_permissions $ ./perf-with-kcore record pt_uname -e intel_pt// -- uname Recording Using /home/ahunter/bin/perf perf version 3.15.rc3.g4549ba /home/ahunter/bin/perf record -o pt_uname/perf.data -e intel_pt// -- uname Linux [ perf record: Woken up 3 times to write data ] [ perf record: Captured and wrote 0.023 MB pt_uname/perf.data ] Copying kcore [sudo] password for ahunter: Done $ tools/perf/perf-with-kcore.sh script pt_uname | head Using /home/ahunter/bin/perf perf version 3.15.rc3.g4549ba /home/ahunter/bin/perf script -i pt_uname/perf.data --kallsyms=pt_uname/kcore_dir/kallsyms swapper 0 [002] 161533.969666: sched:sched_switch: swapper/2:0 [120] R ==> perf:11316 [120] :11315 11315 [003] 161533.969704: sched:sched_switch: perf:11315 [120] S ==> swapper/3:0 [120] :11316 11316 [002] 161533.969783: sched:sched_switch: perf:11316 [120] R ==> migration/2:33 [0] :33 33 [002] 161533.969791: sched:sched_switch: migration/2:33 [0] S ==> swapper/2:0 [120] swapper 0 [003] 161533.969792: sched:sched_switch: swapper/3:0 [120] R ==> perf:11316 [120] :11316 11316 [003] 161533.970062: branches: 0 [unknown] ([unknown]) => ffffffff810532fa native_write_msr_safe ([kernel.kallsyms]) :11316 11316 [003] 161533.970062: branches: ffffffff810532fd native_write_msr_safe ([kernel.kallsyms]) => ffffffff81035b31 pt_config_start ([kernel.kallsyms]) Signed-off-by: Adrian Hunter Cc: David Ahern Cc: Frederic Weisbecker Cc: Jiri Olsa Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/r/1406786474-9306-30-git-send-email-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo
