Cover letter [RFC Patch 0/9] Hardware Breakpoint interfaces - v2
Hi All,
Please find the latest set of patches that introduce kernel
interfaces to use Hardware Breakpoint registers and an implementation for x86 (and x86_64) architecture.
The patches have undergone changes to incorporate the suggestions for the previous patchset - including removal of support for instruction breakpoint, and are based off 2.6.28-rc7. The patches have been tested on x86 architecture along with kprobes, however they're posted as RFC owing to the many pending tasks (refer
http://lkml.org/lkml/2008/10/7/127 for details).
Thanks,
K.Prasad
