Subject: [PATCH v1 0/3] Target to enable paging from temporary RAM Done
Date: Tue, 9 May 2023 18:22:50 +0800 [thread overview]
Message-ID: <20230509102253.16632-1-jiaxin.wu@intel.com> (raw)
For arch X64, system will enable the page table in SPI to cover 0-512G
range via CR4.PAE & MSR.LME & CR0.PG & CR3 setting. Existing code doesn't
cover the higher address access above 512G before memory-discovered
callback. This series patches provide the solution to enable paging from
temporary RAM Done.
Jiaxin Wu (3):
UefiCpuPkg/SecCore: Migrate page table to permanent memory
UefiCpuPkg/CpuMpPei: Enable PAE page table if CR0.PG is not set
MdeModulePkg/DxeIpl: Align Page table Level setting with previous
level.
