[v2] Enhanced SMM support to AMD-based x86 systems.

[edk2] [PATCH v2 2/9] UefiCpuPkg: PiSmmCpuDxeSmm driver.
Posted by Leo Duran 7 years, 2 months ago
Introduce a couple of FixedPCDs to replace Intel-specific macros.
The new PCDs will allow SMM support on AMD-based x86 systems.

1) PcdCpuSmmSmramSaveStateMapOffset - SMRAM Save State Map Offset.
2) PcdCpuSmmPSDOffset - Processor SMM Descriptor Offset in SMRAM.
