Hi guys,
Does perf support different length of user-space hw_breakpoint, such as HW_BREAKPOINT_LEN_1/HW_BREAKPOINT_LEN_2/HW_BREAKPOINT_LEN_4/ HW_BREAKPOINT_LEN_8?
Seems perf only support HW_BREAKPOINT_LEN_4/sizeof(long) by default from the source code and simple test.
May I have your opinions if I want to trace different bytes of hw_breakpoint addr?
Thanks,
Xia Kaixu
