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 (6): MdePkg: Add PcdSpeculationBarrierType MdePkg/BaseLib: Use PcdSpeculationBarrierType QuarkPlatformPkg: Set PcdSpeculationBarrierType to CPUID UefiCpuPkg/MpInitLib: Avoid MSR_IA32_APIC_BASE for single core QuarkSocPkg/SmmAccessDxe: Set region to UC on SMRAM close QuarkPlatformPkg/PlatformInit: Resolve ResetSystemLib name collision MdePkg/Library/BaseLib/BaseLib.inf | 1 + MdePkg/Library/BaseLib/X86SpeculationBarrier.c | 8 ++++++-- MdePkg/MdePkg.dec | 9 +++++++++ MdePkg/MdePkg.uni | 8 ++++++++ .../Platform/Pei/PlatformInit/MemoryCallback.c | 6 +++--- .../Pei/PlatformInit/PlatformEarlyInit.h | 4 ++-- QuarkPlatformPkg/Quark.dsc | 7 ++++++- QuarkPlatformPkg/QuarkMin.dsc | 5 +++++ .../Smm/Dxe/SmmAccessDxe/SmmAccess.inf | 3 ++- .../Smm/Dxe/SmmAccessDxe/SmmAccessDriver.c | 18 +++++++++++++++++- .../Smm/Dxe/SmmAccessDxe/SmmAccessDriver.h | 3 ++- UefiCpuPkg/Library/MpInitLib/PeiMpLib.c | 15 ++++++++++++++- 12 files changed, 75 insertions(+), 12 deletions(-) -- 2.21.0.windows.1 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
