OvmfPkg/SmmRelocationLib: Add library instance for OVMF2024-05-08T01:53:58+00:00Jiaxin Wujiaxin.wu@intel.com2024-04-08T01:08:23+00:00urn:sha1:3dfd64305b7f46da6f98ae15c87227b0fb55f726
There are below 2 differences between AMD & OVMF according
existing implementation:
1.The mode of the CPU check is different between the AMD & OVMF.
OVMF:
CpuSaveState->x86.SMMRevId & 0Xffff
AMD:
LMAValue = (UINT32)AsmReadMsr64 (EFER_ADDRESS) & LMA
2.Existing SmBase configuration is different between the
AMD & OVMF.
OVMF:
if ((CpuSaveState->x86.SMMRevId & 0xFFFF) == 0) {
CpuSaveState->x86.SMBASE = mSmBaseForAllCpus[CpuIndex];
} else {
CpuSaveState->x64.SMBASE = mSmBaseForAllCpus[CpuIndex];
}
AMD:
AmdCpuState->x64.SMBASE = mSmBaseForAllCpus[CpuIndex];
This patch provides the SmmRelocationLib library instance
for OVMF to handle the logic difference, and it won't change
the existing implementation code logic.
