perf changes for v3.5
Linus,
Please pull the latest perf-core-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-for-linus
HEAD: 73787190d04a34e6da745da893b3ae8bedde418f Merge branch 'perf/parse-events-4' of git://github.com/fweisbec/tracing into perf/core
Lots of changes:
- (much) improved assembly annotation support in perf report, with jump visualization, searching, navigation, visual output improvements and more.
- kernel support for AMD IBS PMU hardware features. Notably 'perf record -e cycles:p' and 'perf top -e cycles:p' should work without skid now, like PEBS does on the Intel side, because it takes advantage of IBS transparently.
- the libtracevents library: it is the first step towards unifying tracing tooling and perf, and it also gives a tracing library for external tools like powertop to rely on.
- infrastructure: various improvements and refactoring of the UI modules and related code
- infrastructure: cleanup and simplification of the profiling targets code (--uid, --pid, --tid, --cpu, --all-cpus, etc.)
- tons of robustness fixes all around
- various ftrace updates: speedups, cleanups, robustness improvements.
- typing 'make' in tools/ will now give you a menu of projects to build and a short help text to explain what each does.
- ... and lots of other changes I forgot to list.
The perf record make bzImage + perf report regression you reported should be fixed.
Thanks,
Ingo
