Hi All, Please review a set of patches that enhance the perf-events infrastructure to use hw-breakpoints layer to monitor accesses over kernel-space addresses/symbols, apart from bringing a few related enhancements to the hw-breakpoint layer.
These patches are still under development and is based off -tip tree (commit 77a088cd30a7bd2c700bf57544732fff6971305e) and are known to have a few issues (listed in patch 3/3).
Patch 1/4: Allow per-cpu kernel-space Hardware Breakpoint requests (originally posted here http://lkml.org/lkml/2009/8/17/172) Patch 2/4: Allow breakpoints to be enabled/disabled on the fly (without yielding them to other contenders). Patch 3/4: Bugfix HW-BKPT: Fix traceback seen when resuming after suspend-to-ram Patch 4/4: Enhance perf-events to profile memory accesses over kernel symbols
Comments on the same will be appreciated!
Thanks, K.Prasad
