New in V3 ========= * Remove change to MpInitLib to avoid use of MSR_IA32_APIC_BASE. That change was not safe because an AP could call the PCD Protocol/PPI. * Add new MpInitLibUp for uni-processor platforms. * Update Quark DSC files to use MpInitLibUp for uni-processor platforms. * Add missing CpuLub library class to the CpuMpPei INF file
New in V2 ========= * Add PcdSpeculationBarrierType to select between LFENCE, CPUID, and no operation in the x86 implementation of the BaseLib function SpeculationBarrier(). * Set PcdSpeculationBarrierType to CPUID on Quark platforms. This series of patches resolves a few issues with building and booting Quark platforms. * Resolve name collision from API added to ResetSystemLib * Set SMRAM region to UC when SMRAM region is closed * Do no use LFENCE if CPU does not support SSE2 * Avoid MSR_IA32_APIC_BASE if there is only one CPU Cc: Kelly Steele <kelly.ste...@intel.com> Cc: Liming Gao <liming....@intel.com> Cc: Eric Dong <eric.d...@intel.com> Cc: Ray Ni <ray...@intel.com> Cc: Laszlo Ersek <ler...@redhat.com> Signed-off-by: Michael D Kinney <michael.d.kin...@intel.com> Michael D Kinney (8): MdePkg: Add PcdSpeculationBarrierType MdePkg/BaseLib: Use PcdSpeculationBarrierType QuarkPlatformPkg: Set PcdSpeculationBarrierType to CPUID UefiCpuPkg/MpInitLibUp: Add uniprocessor MpInitLib UefiCPuPkg/CpuMpPei: Add missing CpuLib class QuarkPlatformPkg: Use uniprocessor MpInitLibUp QuarkSocPkg/SmmAccessDxe: Set region to UC on SMRAM close QuarkPlatformPkg/PlatformInit: Resolve ResetSystemLib name collision MdePkg/Library/BaseLib/BaseLib.inf | 1 + .../Library/BaseLib/X86SpeculationBarrier.c | 8 +- MdePkg/MdePkg.dec | 9 + MdePkg/MdePkg.uni | 8 + .../Pei/PlatformInit/MemoryCallback.c | 6 +- .../Pei/PlatformInit/PlatformEarlyInit.h | 4 +- QuarkPlatformPkg/Quark.dsc | 10 +- QuarkPlatformPkg/QuarkMin.dsc | 8 +- .../Smm/Dxe/SmmAccessDxe/SmmAccess.inf | 3 +- .../Smm/Dxe/SmmAccessDxe/SmmAccessDriver.c | 18 +- .../Smm/Dxe/SmmAccessDxe/SmmAccessDriver.h | 3 +- UefiCpuPkg/CpuMpPei/CpuMpPei.inf | 3 +- UefiCpuPkg/Library/MpInitLibUp/MpInitLibUp.c | 407 ++++++++++++++++++ .../Library/MpInitLibUp/MpInitLibUp.inf | 37 ++ .../Library/MpInitLibUp/MpInitLibUp.uni | 14 + UefiCpuPkg/UefiCpuPkg.dsc | 3 +- 16 files changed, 525 insertions(+), 17 deletions(-) create mode 100644 UefiCpuPkg/Library/MpInitLibUp/MpInitLibUp.c create mode 100644 UefiCpuPkg/Library/MpInitLibUp/MpInitLibUp.inf create mode 100644 UefiCpuPkg/Library/MpInitLibUp/MpInitLibUp.uni -- 2.21.0.windows.1 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
