Siyuan: This is new feature, please add it into https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-Release-Planning
And, FIT header file is moved from edk2-platform to edk2. After this change, you also need to remove the one in edk2-platform. Right? Thanks Liming -----Original Message----- From: Fu, Siyuan <siyuan...@intel.com> Sent: 2020年1月8日 12:25 To: devel@edk2.groups.io Cc: Kinney, Michael D <michael.d.kin...@intel.com>; Gao, Liming <liming....@intel.com>; Dong, Eric <eric.d...@intel.com>; Ni, Ray <ray...@intel.com>; ler...@redhat.com Subject: [Patch 0/2] Shadow microcode patch according to FIT microcode table. The existing MpInitLib will shadow the microcode update patches from flash to memory and this is done by searching microcode region specified by PCD PcdCpuMicrocodePatchAddress and PcdCpuMicrocodePatchRegionSize. This brings a limition to platform FW that all the microcode patches must be placed in one continuous flash space. This patch set shadows microcode update according to FIT microcode entries if it's present, otherwise it will fallback to original logic (by PCD). Patch 1/2: Add FIT header file to MdePkg. Patch 2/2: Update microcode loader to shadow microcode according to FIT.
