Title:
[MTL] x86: Fix Cache info sysfs is not populated
Status in intel:
New
Status in linux package in Ubuntu:
New
Bug description:
[Description]
The interface /sys/devices/system/cpu/cpu*/cache is empty. In Meteorlake,
not all CPUs have the same number of subleaves in the CPUID 4 leaf. The compute
die CPUs have 3 subleaves whereas the CPUs in the SoC die have 2. This problem
happens because Linux assumes that all CPUs have the same number of subleaves.
