Ingo,
Please pull the perf/core-v2 branch that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git perf/core-v2
HEAD: 33252c1bb36dd7405f412a9ef8fc05dec995064a
It has been acked by Jiri and Oleg. --- Summary:
* Extend breakpoint tools and core to support address range through perf event with initial backend support for AMD extended breakpoints. Syntax is:
perf record -e mem:addr/len:type
For example set write breakpoint from 0x1000 to 0x1200 (0x1000 + 512)
perf record -e mem:0x1000/512:w
* Clean up a bit breakpoint code validation ---
Thanks, Frederic ---
