From: Jeff Fan Date: Tue, 7 Mar 2017 11:23:12 +0000 (+0800) Subject: UefiCpuPkg: Add CPU Features PEI/DXE drivers X-Git-Tag: edk2-stable201903~4349 X-Git-Url: https://git.proxmox.com/?p=mirror_edk2.git;a=commitdiff_plain;h=82e75ac65abdfca034cfb38edcee8a7cbc6e6271 UefiCpuPkg: Add CPU Features PEI/DXE drivers They will consume Register CPU Features library to detect and initialize CPU features. CpuFeaturesPei driver is used to initialize CPU features in PEI phase. CpuFeaturesDxe driver is used to initialize CPU features in DXE phase. Add PcdCpuFeaturesInitAfterSmmRelocation and PcdCpuFeaturesInitOnS3Resume that consumed by CpuFeaturesPei and CpuFeaturesDxe.
