[edk2] [PATCH] UefiCpuPkg/SecPeiDxeTimerLibUefiCpu: Add GetIntendFsbFrequency()
The current implementation gets CPU FSB frequency by PcdFSBClock. However, IA32
SDM defined accurate FSB for some specific processors. Actually, we could try to
get FSB frequency by hardware instead of by PcdFSBClock. If FSB frequency is not
documented by IA32 SDM, we still could get it by PcdFSBClock.

[edk2] [PATCH v3 2/3] UefiCpuPkg/MpInitLib: Check APIC mode change around AP function
If APIC ID values are changed during AP functions execution, we need to update
new APIC ID values in local data structure accordingly.

APIC ID value changed.

Current X2APIC is enabled in MpInitLib (used by CpuMpPei and CpuDxe) to follow
SDM suggestion. That means we only enable X2APIC if we found there are any
initial CPU ID value >= 255.
This patch is to provide one chance for platform to enable X2APIC even there is
no any initial CPU ID value >= 255.

[edk2] [PATCH 2/2] UefiCpuPkg/MpInitLib: Check APIC mode change around AP function
If APIC ID values are changed during AP functions execution, we need to update
new APIC ID values in local data structure accordingly.
But if APIC mode change happened during AP function execution, we do not support
APIC ID value changed.

[edk2] [PATCH 1/2] UefiCpuPkg/CpuCommonFeaturesLib: Support X2APIC enable
Current X2APIC is enabled in MpInitLib (used by CpuMpPei and CpuDxe) to follow
SDM suggestion. That means we only enable X2APIC if we found there are any
initial CPU ID value >= 255.
This patch is to provide one chance for platform to enable X2APIC even there is
no any initial CPU ID value >= 255.

[edk2] [PATCH] UefiCpuPkg/PiSmmCpuDxeSmm: Check ProcessorId == INVALID_APIC_ID
If PcdCpuHotPlugSupport is TRUE, gSmst->NumberOfCpus will be the
PcdCpuMaxLogicalProcessorNumber. If gSmst->SmmStartupThisAp() is invoked for
those un-existed processors, ASSERT() happened in ConfigSmmCodeAccessCheck().
This fix is to check if ProcessorId is valid before invoke
gSmst->SmmStartupThisAp() in ConfigSmmCodeAccessCheck() and to check if
ProcessorId is valid in InternalSmmStartupThisAp() to avoid unexpected DEBUG
error message displayed.

[edk2] [PATCH 0/2] Borrow the space below 1MB for AP reset vector
Current, CpuMpPei will find the available memory space below 1MB for AP reset vector. And CpuMpPei will build resource HOB on this range to prevent other PEI modules to use this range. However, on some FSP usage model, this range maybe used by the code out of FSP. CpuMpPei may change the original memory contents and cause other code crash. We could update CpuMpPei not to change the original contents of this range around AP waking up. Thus, it will not impact the other code on FSP usage model. This updating is tiny and less impact on performance. https://bugzilla.tianocore.org/show_bug.cgi?id=500 Cc: Feng Tian Cc: Michael Kinney Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jeff Fan Jeff Fan (2): UefiCpuPkg/MpInitLib: save/restore original contents UefiCpuPkg/MpInitLib: needn't to allocate AP reset vector UefiCpuPkg/Library/MpInitLib/MpLib.h | 22 +- UefiCpuPkg/Library/MpInitLib/PeiMpInitLib.inf | 6 +- UefiCpuPkg/Library/MpInitLib/PeiMpLib.c | 107 +- 3 files changed, 5 insertions(+), 130 deletions(-) -- 2.9.3.windows.2 ___ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel

In PEI phase, BSP did not program vitural wired mode while APs did.
Move program virtual wired mode from CpuDxe to MpInitLib, thus it could benefit
on both CpuDxe and CpuMpPei.

[edk2] [PATCH 4/9] UefiCpuPkg/CpuExceptionHandlerLib: Add DumpModuleImageInfo()
Add internal DumpModuleImageInfo() to replace FindModuleImageBase(). It will
consume PeCoffGetEntrypointLib's PeCoffSerachImageBase() to get PE/COFF image
base.

[edk2] [PATCH v2] UefiCpuPkg/MpLib.c: Add checking CR0 PG bit
If CR0 PG bit is not set, it means paging is not enabled on BSP. Thus, Execute
Disable feature is not working actually. Thus, we cannot enable it on APs.
v2:
Correct the commit log.

[edk2] [PATCH 2/2] UefiCpuPkg/AcpiCpuData.h: Support >4GB MMIO address
The current CPU_REGISTER_TABLE_ENTRY structure only defined UINT32 Index to
indicate MSR/MMIO address. It's ok for MSR because MSR address is UINT32 type
actually. But for MMIO address, UINT32 limits MMIO address exceeds 4GB.
This update on CPU_REGISTER_TABLE_ENTRY is to add additional UINT32 field
HighIndex to indicate the high 32bit MMIO address and original Index still
indicate the low 32bit MMIO address.
This update makes use of original padding space between ValidBitLength and
Value to add HighIndex.

[edk2] [PATCH 1/2] UefiCpuPkg/RegisterCpuFeaturesLib: Define Index to UINT64
The input parameter Index of PreSmmCpuRegisterTableWrite() and CpuRegisterTableWrite() is defined as UINT32. Index is MSR/MMIO address that will be saved in CPU register table. UINT32 blocks the MMIO address > 4GB. This fix is to define Index to UINT64 instead of UINT32.

CpuFeatureEntry will be set before using it. But VS2012 build reported the build

This fix is to set CpuFeatureEntry initial value and add ASSERT check later.

[edk2] [PATCH v5 10/11] UefiCpuPkg: Add NULL CPU Common Features Library instance
This NULL CPU common Features Library instance will register some CPU features
defined in Intel(R) 64 and IA-32 Architectures Software Developer's Manual,
Volume 3, September 2016, Chapter 35 Model-Specific-Registers (MSR).
Add PCD PcdCpuClockModulationDutyCycle and PcdIsPowerOnReset consumed by NULL
CPU Common Features Library instance.
v2:
1. Using MSR_IA32_EFER to enable/disable NX feature instead of using
MSR_IA32_MISC_ENABLE.
2. Fix bug that SMX and VMX feature is swapped.
v3:
1. Add AesniGetConfigData() to get current register state.
v5:
1. Move MSR reading from AesniGetConfigData() to AesniSupport().

[edk2] [PATCH v4 00/11] Add CPU features driver
This serial of patches will add CPU featuers initialization on boot time. 1) One new Register CPU Features Library and instances are added to provide the capability to register CPU feature's detect/initialize services. 2) One new NULL class CPU Commong Features Library instance is added to provide detect/initialize servcies of CPU features defined in SDM. 3) New CPU features PEI/DXE drivers are added to initialize CPU features in PEI phase or DXE phase, by consuming Register CPU Features Library. https://bugzilla.tianocore.org/show_bug.cgi?id=421 The whole updated UefiCpuPkg v4 could be accessed at https://github.com/JeffFan/edk2/tree/CpuFeaturesV4/UefiCpuPkg for review. v2: #9: Format debug messages. #10: 1. Using MSR_IA32_EFER to enable/disable NX feature instead of using MSR_IA32_MISC_ENABLE. 2. Fix bug that SMX and VMX feature is swapped. v3: #9: Trim white space at end of line. #10: Add AesniGetConfigData() to get current register state. v4: #3, #8, #9: Fix GCC complied issue.

[edk2] [PATCH v4 08/11] UefiCpuPkg/Include/Library: Add Register CPU Features Library
Register CPU Features Library is used to register/manage/program CPU features.
NULL CPU features library instance could consume it register CPU features
functions.
CPU Feature module could consume this library to detect/analysis/program CPU
features on BSP/APs.
v4:
Fix GCC build issue.

[edk2] [PATCH v3 10/11] UefiCpuPkg: Add NULL CPU Common Features Library instance
This NULL CPU common Features Library instance will register some CPU features
defined in Intel(R) 64 and IA-32 Architectures Software Developer's Manual,
Volume 3, September 2016, Chapter 35 Model-Specific-Registers (MSR).
Add PCD PcdCpuClockModulationDutyCycle and PcdIsPowerOnReset consumed by NULL
CPU Common Features Library instance.
v2:
1. Using MSR_IA32_EFER to enable/disable NX feature instead of using
MSR_IA32_MISC_ENABLE.
2. Fix bug that SMX and VMX feature is swapped.
v3:
1. Add AesniGetConfigData() to get current register state.

[edk2] [PATCH] UefiCpuPkg/CpuDxe: Remove MSR_IA32_MISC_ENABLE check
The architectural MSR MSR_IA32_MISC_ENABLE is not supported by AMD processors.
Because reading CPUID.8001H:EDK[20] is enough to check if XD feature is
supported or not, we just remove checking MSR_IA32_MISC_ENABLE(0x1A0).

[edk2] [PATCH 07/11] UefiCpuPkg: Add GUID gEdkiiCpuFeaturesInitDoneGuid
GUID gEdkiiCpuFeaturesInitDoneGuid is used to indicate if CPU features have been
initialized.
On PEI phase, one gEdkiiCpuFeaturesInitDoneGuid PPI will be installed after CPU
features initialized.
On DXE phase, one gEdkiiCpuFeaturesInitDoneGuid Protocol will be installed after
CPU features initialized.

[edk2] [PATCH 11/11] 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.
