[edk2-devel] [PATCH v2 0/4] UefiCpuPkg/StandaloneMmCpuFeaturesLib: Add Standalone MM support

[Michael Kubacki]

From: Michael Kubacki <michael.kubacki at microsoft.com>

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3218

This patch series is v2 of the following v1 patch:
https://edk2.groups.io/g/devel/message/71626

Due to some pre-existing design issues in the library that affected
that patch, it was suggested to first address those issues and then
add the new INF StandaloneMmCpuFeaturesLib.inf. The first two
patches in this series primarily address those concerns.

The present SmmCpuFeaturesLib implementation in UefiCpuPkg can be
useful for IA32/X64 platforms that need a library instance for
a Standalone MM environment. Much of the logic can be reused and a
new INF can isolate the differences unique to Standalone MM.

PATCH v2 1/4 and PATCH v2 2/4 focus on fixing pre-existing design
issues.

PATCH v2 3/4 and PATCH v2 4/4 focus on the changes needed to add
Standalone MM support.
