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,
Tiezhu

I'm not finding it in the debian cross build packages:

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

yeah, my bad, since perf wasn't supported on MIPS, how could cross build
environments have the needed files? Stooooopid me, sorry. :-) I'll
retest after adding the needed files to my test containers.

Then I had to add this one on top:

Committer notes:

Do it as __perf_reg_name() to cope with:
