Hi Jean,
I have applied this patchset on aarch64 upstream branch,cross-compiled for arm64 and try running some tests for hardware breakpoints.
I cross-compiled perf using linaro toolchain "gcc-linaro-aarch64-linux-gnu-4.7-2013.04-20130415_linux" as $ cd tools/perf/ $ make LDFLAGS=-static ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
Copied the static binary to my initrd image and tried running tests to place hw_breakpoint on an kernel symbol as:
# perf record -e "mem:0xffffffc00013f640:x"
Right, but that's not a valid invocation of perf. You have to give it something to record. Something like:
# perf record -e mem:0xffffffc00013f640:x -a -- sleep 10
Hi Will,
Thanks for correcting me, now I see perf record working :)

for example.
