Thank you in advance.

[khuey]

Try adding Meteor Lake with 766e0e8 as a template and then running make check. You'll need taskset -c 0 make check or similar to limit rr to the P-cores.

[FurryAcetylCoA]

Sorry for the late reply. Some test keep halting my system

If add 0xb06d0 as Meteor Lake or as it own(lunar lake) with rcb_cntr_event==0x5111c4

It will cause random hangup like

zsh: hangup     sudo taskset -c 0 ctest

(not always hangup at this test, sometime( like 1/10) it will pass this test and hangup elsewhere)
I tried sudo sysctl kernel.perf_event_paranoid=0 and sudo sysctl kernel.yama.ptrace_scope=0 and running test as root but it does not help.

[khuey]

Hmm, that's pretty weird. Can you try a different shell (e.g. bash)?

[FurryAcetylCoA]

I did a system update and after that if I add my cpu using 0x100005111c4
and run the test as normal user

And once run the test as root, I can't launch any X11 program for mysterious reason..

[khuey]

The remaining failures are likely due to your kernel version or some system configuration. Those results do indicate that the performance counters are working. We will take that PR, thanks.

[khuey]

I think we're good here now.
