Subject: [edk2-devel] [PATCH 00/10] OvmfPkg/ResetVector: cleanup and add 5-level paging support.
Date: Thu, 22 Feb 2024 12:54:25 +0100 [thread overview]
Message-ID: <20240222115435.85794-1-kraxel@redhat.com> (raw)
So I ran with the suggestion by Laszlo to move the page table setup into
macros and untangle the non-CoCo / TDX / SEV code paths. The first five
patches of the series are doing that (without functional changes).
Support for 5-level paging is added by the following five patches. This
way it is indeed easier to understand. Additional bonus is that the
patches can be splitted into smaller pieces and 5-level paging for the
three cases (non-CoCo / TDX / SEC) can be enabled independently.
The SEV patches (#9 + #10) are included here for completeness, but it is
probably a good idea to merge them only after 5-level paging support was
added to BaseMemEncryptSevLib. This way we can turn on 5-level paging
support without breaking SEV.
