Revision 38776cc45eb7603df4735a0410f42cffff8e71a1 authored by Kan Liang on 08 May 2023, 14:02:06 UTC, committed by Peter Zijlstra on 24 May 2023, 20:19:41 UTC
The number of CHAs from the discovery table on some SPR variants is
incorrect, because of a firmware issue. An accurate number can be read
from the MSR UNC_CBO_CONFIG.
