Cover letter [PATCH 0/2] oprofile: enable 'operf' perf_events mode
From: Tom Zanussi <[email protected]>
This patchset fixes oprofile-0.9.8 so that it finds perf_events and configures accordingly to enable 'operf' and not just 'legacy oprofile'
I've added a new section on operf to the Yocto Tracing and Profiling Guide' (just the wiki version for now, until I can submit a patch for the official Guide):
https://wiki.yoctoproject.org/wiki/Tracing_and_Profiling#operf
I've tested this on real hardware (x86 crownbay), and build-tested on the other arches (powerpc didn't build due to YOCTO bug #3717, but that's not a regression).
The following changes since commit cfb082961a6c9ac3d65738031c4071210529cd07:
bitbake: build.py: Dump out performance data of individual tasks (2013-01-28 14:49:05 +0000)
