Patch #1 + #2 fix MdeModulePkg/DxeIplPeim to not assert in case a 5-level enabled build runs in 4-level paging mode.
Patch #2 - #4 update OvmfPkg ResetVector, adding support for 5-level paging (setup 5-level page tables in case both la57 and gigabyte pages are supported by the vCPU). Patch #5 updates PlatformInitLib for 5-level paging support (update PhysBits calculation). Known issues / limitations: - BaseMemEncryptSevLib must be updated to also support 5-level paging for full 5-level paging support in SEV mode. The patch series does *not* enable 5-level paging by default. Building with 5-level paging support can be done by compiling OVMF with '--pcd PcdUse5LevelPageTable=TRUE'. v3: - add resetvector fixes for sev and tdx v2 changes: - fix sev/tdx handling with 5-level paging. - more comments for 5-level page table setup. - improve PAGE_* naming (new patch #3). - rename Page5LevelSupported to Page5LevelEnabled (new patch #2). - pick up some review tags.
