Subject: perf support user-space hw_breakpoint?

Hi guys,

Does perf support user space hw_breakpoint based on per-task?

perf already support kenerl space hw_breakpoint, but there don't have
any example for
user-space hw_breakpoint in code base(and never metion it).
>From perf api point of view, it should support per-task hw_breakpoint easily.
but I still want to make sure that?(badly I don't have any linux
machine to test it now:))

Thanks.
