[BUG] Intel uncore frequency driver missing half of each package on 6.9.4

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

on a dual INTEL(R) XEON(R) PLATINUM 8558 system, we've upgraded from
6.8.X to 6.9.4 and noticed that turbostat is no longer working.

turbostat: /sys/devices/system/cpu/intel_uncore_frequency/package_01_die_00/current_freq_khz:
open failed: No such file or directory

ls -la /sys/devices/system/cpu/intel_uncore_frequency/
total 0
drwxr-xr-x   4 root root 0 Jun 17 15:29 .
drwxr-xr-x 204 root root 0 Jun 15 21:45 ..
drwxr-xr-x   2 root root 0 Jun 17 15:29 package_00_die_00
drwxr-xr-x   2 root root 0 Jun 17 15:29 package_01_die_01

Seems to be missing a die on each package?

Best regards,

Darius.
