Hi Arnaldo,
The kernel part patch #1 has been merged.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1ddc96bd42da
Could the perf tool patches #2 and #3 have a chance to be merged before
5.12-rc1?
If yes, we can use this feature in 5.12-rc1.
Thanks, applied, should make it into 5.12-rc1.
First we'll have to fix this problem:

Sorry for the late reply. I asked for a leave yesterday.
asm/perf_regs.h is a new added file in the patch #1,
the patch link is:
https://lore.kernel.org/patchwork/patch/1375477/
the commit is:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/mips/include/uapi/asm/perf_regs.h?id=1ddc96bd42da
So we should build patch #2 based on patch #1.
Thanks,
Tiezhu
