[edk2] [PATCH 0/2] [UefiCpuPkg] Support 64bit MMIO address in CPU Register Table

Posted by Jeff Fan 7 years, 7 months ago

The current CPU_REGISTER_TABLE_ENTRY structure only defined UINT32 Index to
indicate MSR/MMIO address. It's ok for MSR because MSR address is UINT32 type
actually. But for MMIO address, UINT32 limits MMIO address exceeds 4GB.
