Subject: [edk2-devel][edk2-platforms][PATCH v1 2/5] Silicon/Intel: Port SmmControl protocol to PPI for S3
Date: Mon, 29 Aug 2022 16:36:17 -0400	[thread overview]
Message-ID: <5d3ee2d57676168af4d0a001683a719a5e57b66a.1661799519.git.benjamin.doron00@gmail.com> (raw)
In-Reply-To: <cover.1661799519.git.benjamin.doron00@gmail.com>

S3 resume may require communication with SMM, for which we need the
SmmControl PPI. Therefore, port the DXE drivers to a library, like there
is for SMM Access.

As the registers are common across Intel platforms in the tree, while
a helper function definition is not, implement a new library as a
compatibility shim.

Tested, working on Kabylake. Further testing required after the refactor
for compatibility.
