Subject: [PATCH 9/9] UefiCpuPkg: SmmCpuFeaturesLib library.
Date: Tue, 3 Oct 2017 17:08:29 -0500 [thread overview]
Message-ID: <1507068509-5148-10-git-send-email-leo.duran@amd.com> (raw)
In-Reply-To: <1507068509-5148-1-git-send-email-leo.duran@amd.com>
Add a FixedPCD to replace an Intel-specific hard-coded macro.
The new PCD allows SMM support on AMD-based x86 systems.
PcdCpuSmmPSDOffset - Processor SMM Descriptor Offset in SMRAM.
