Description LeoLiu-oc zhaoxin_group 2024-06-28 15:48:14 UTC
该补丁使得可以直接通过BIOS设定CMCI阈值。

In the Linux kernel, the CMCI threshold is set to 1 by default. This patch
prevents Linux from overwriting the CMCI threshold set by the bios. With
this patch, the CMCI threshold can be set through the BIOS, which can also
avoid CMCI storms, on Zhaoxin/Centaur CPUs.
