Subject: [edk2-devel] [PATCH] MdePkg/Tdx.h: Fix the order of NumVcpus and MaxVcpus
Date: Wed, 26 Jun 2024 21:26:44 -0400 [thread overview]
Message-ID: <20240627012644.2545665-1-xiaoyao.li@intel.com> (raw)
For TDCALL leaf TDG.VP.INFO, the bit 31:0 in R8 returns NUM_VCPUS and
bit 63:32 in R8 returns MAX_VCPUS. Current struct
TDCALL_INFO_RETURN_DATA defines them in wrong order.
