[edk2-devel] [PATCH 08/10] OvmfPkg/ResetVector: wire up 5-level paging for TDX

2024-02-22 Thread Gerd Hoffmann
BSP workflow is quite simliar to the non-coco case. TDX_WORK_AREA_PGTBL_READY is used to record the paging mode: 1 == 4-level paging 2 == 5-level paging APs will look at TDX_WORK_AREA_PGTBL_READY to figure whenever they should enable 5-level paging or not. Signed-off-by: Gerd Hoffmann ---
