Subject: [V1 PATCH 1/1] MdePkg: TDX: Correct TDCALL_INFO_RETURN_DATA layout
Date: Wed, 15 Feb 2023 19:50:42 +0000 [thread overview]
Message-ID: <20230215195042.1094110-1-vannapurve@google.com> (raw)
TDCALL_INFO should return num_vcpus as lower 4 bytes of r8 register according to
the tdx spec, so reorder num_vcpus and max_vcpus fields to match the spec.
Reference: Table 22.210 TDG.VP.INFO output operands
