Subject: [Patch 0/3] HW-BKPT: Introduce new features to the hw-breakpoint infrastructure
Date: Thu, 27 Aug 2009 01:44:04 +0530 [thread overview]
Message-ID: <20090826201404.GA12766@in.ibm.com> (raw)
Hi All,
Please find a set of patches that implement the features listed
below. This is a sequel to the patchset posted yesterday
http://lkml.org/lkml/2009/8/25/371 and contains a new patch 3/3.
Patch 1/2: Allow per-cpu kernel-space Hardware Breakpoint requests
Patch 2/2: Allow kernel breakpoints to be modified through a new API
Patch 3/3: Allow breakpoints to be enabled/disabled without yielding the
breakpoint request through a new API - enable_hw_breakpoint().
During discussion on LKML, these features were deemed necessary for
effective exploitation of hardware breakpoints by perf-tools.
The patches are based off -tip tree. Kindly let me know your comments
on the same.
Thanks,
K.Prasad
