Subject: [PATCH V3 04/10] OvmfPkg: Add TDX_PT_ADDR defition in ResetVector.nasmb
Date: Tue, 27 Jul 2021 13:42:21 +0800 [thread overview]
Message-ID: <da6579c646c2ba589efcf2a4ab117c52a0196187.1627364332.git.min.m.xu@intel.com> (raw)
In-Reply-To: <cover.1627364332.git.min.m.xu@intel.com>
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
Tdx support 4-level paging or 5-level paging based on the GPAW. If
5-level page table is supported (GPAW is 52), a top level page directory
pointers (1 * 256TB entry) is generated in the memory region defined by
PcdOvmfSecPageTablesBase.
