Re: IBS perf test failures on 9950x3d

Hi Arnaldo,

1) Bunch of IBS kernel fixes went in recently (v6.15-rc1):

   https://lore.kernel.org/r/20250115054438.1021-1-ravi.bangoria@xxxxxxx

   Since you are running on 6.14.5-300.fc42.x86_64, the failures are
   genuine and indicating that kernel should be fixed.

   I'm wondering how would the test cope with the buggy kernel. Or
   probably 'perf test' a wrong place to put such selftests?

2) "mprotect() failed. Permission denied" seems to be because of
   SELinux enforced mode? I'll prepare and post a fix but, even
   with the error, it's just part of the dummy workload function
   so wouldn't break any test functionality.

Thanks,
Ravi
