Subject: [PATCH 0/3] AMD SMCA Updates
Date: Fri, 3 Dec 2021 02:00:14 +0000	[thread overview]
Message-ID: <20211203020017.728440-1-yazen.ghannam@amd.com> (raw)

Hi all,

This set adds supports for SMCA changes in future AMD systems.

Patch 1 adds an "unknown" bank type so that sysfs initialization issues
can be avoided on systems with new bank types.

Patch 2 adds new bank types and error descriptions used in future AMD
systems.

Patch 3 adjusts how SMCA bank information is cached. Future AMD systems
will have different bank type layouts between logical CPUs. So having a
single system-wide cache of the layout won't be correct.

Thanks,
Yazen
