* UefiCpuPkg/AcpiCpuData: update comments on register table fieldsLaszlo Ersek2021-01-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | After commit e992cc3f4859 ("UefiCpuPkg PiSmmCpuDxeSmm: Reduce SMRAM consumption in CpuS3.c", 2021-01-11), it is valid for a CPU S3 Data DXE Driver to set "ACPI_CPU_DATA.PreSmmInitRegisterTable" and/or "ACPI_CPU_DATA.RegisterTable" to 0, in case none of the CPUs needs a register table of the corresponding kind, during S3 resume. Document this fact in the "UefiCpuPkg/Include/AcpiCpuData.h" header file.

* UefiCpuPkg/Feature: Support different thread count per coreRay Ni2020-12-041-3/+13
| | | | | | | | | | | | | | | | | Today's code assumes every core contains the same number of threads. It's not always TRUE for certain model. Such assumption causes system hang when thread count per core is different and there is core or package dependency between CPU features (using CPU_FEATURE_CORE_BEFORE/AFTER, CPU_FEATURE_PACKAGE_BEFORE/AFTER). The change removes such assumption by calculating the actual thread count per package and per core.

* UefiCpuPkg, OvmfPkg: Disable interrupts when using the GHCBTom Lendacky2020-11-101-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3008 The QemuFlashPtrWrite() flash services runtime uses the GHCB and VmgExit() directly to perform the flash write when running as an SEV-ES guest. If an interrupt arrives between VmgInit() and VmgExit(), the Dr7 read in the interrupt handler will generate a #VC, which can overwrite information in the GHCB that QemuFlashPtrWrite() has set. This has been seen with the timer interrupt firing and the CpuExceptionHandlerLib library code, UefiCpuPkg/Library/CpuExceptionHandlerLib/X64/ Xcode5ExceptionHandlerAsm.nasm and ExceptionHandlerAsm.nasm reading the Dr7 register while QemuFlashPtrWrite() is using the GHCB. In general, it is necessary to protect the GHCB whenever it is used, not just in QemuFlashPtrWrite(). Disable interrupts around the usage of the GHCB by modifying the VmgInit() and VmgDone() interfaces: - VmgInit() will take an extra parameter that is a pointer to a BOOLEAN that will hold the interrupt state at the time of invocation. VmgInit() will get and save this interrupt state before updating the GHCB. - VmgDone() will take an extra parameter that is used to indicate whether interrupts are to be (re)enabled. Before exiting, VmgDone() will enable interrupts if that is requested.

* UefiCpuPkg/VmgExitLib: Add interfaces to set/read GHCB ValidBitmap bitsTom Lendacky2020-11-101-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3008 In upcoming patches, the setting of the bits in the GHCB ValidBitmap will be performed in multiple places. In order to reduce code duplication, add an interface, VmgSetOffsetValid(), to VmgExitLib library to perform this function. Also, to keep management of the ValidBitmap within the library, add an inteface, VmgIsOffsetValid(), to return whether the bit in the ValidBitmap is set for a specified offset. The new VmgSetOffsetValid() function is a VOID function and will be an empty function in the VmgExitLibNull implementation of the VmgExitLib library. The new VmgIsOffsetValid() function returns a BOOLEAN to indicate if the offset is valid. This will always return FALSE in the VmgExitLibNull implementation of the VmgExitLib library.

* UefiCpuPkg: Remove FIT based microcode shadow logic from MpInitLib.Siyuan Fu2020-02-141-0/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit c7c964b and dd01704 add header file for FIT table and update MpInitLib to support FIT based microcode shadow operation. There are comments that FIT is Intel specific specification instead of industry standard, which should not be placed in EDK2 MdePkg and UefiCpuPkg. So this patch adds a platform PPI for the microcode shadow logic, and remove the FIT related code from EDK2. The FIT based microcode shadow support will be implemented as a new platform PEIM in IntelSiliconPkg in edk2-platforms. This patch doesn't provide a DXE version shadow microcode protocol, a platform which only uses DxeMpInitLib instance only supports PCD based microcode shadowing.

* UefiCpuPkg/CpuFeature: Introduce First to indicate 1st unit.Ray Ni2020-02-141-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1584 The flow of CPU feature initialization logic is: 1. BSP calls GetConfigDataFunc() for each thread/AP; 2. Each thread/AP calls SupportFunc() to detect its own capability; 3. BSP calls InitializeFunc() for each thread/AP. There is a design gap in step #3. For a package scope feature that only requires one thread of each package does the initialization operation, what InitializeFunc() currently does is to do the initialization operation only CPU physical location Core# is 0. But in certain platform, Core#0 might be disabled in hardware level which results the certain package scope feature isn't initialized at all. The patch adds a new field First to indicate the CPU's location in its parent scope. First.Package is set for all APs/threads under first package; First.Core is set for all APs/threads under first core of each package; First.Thread is set for the AP/thread of each core.

* UefiCpuPkg: Merge StuffRsb.inc files into one in UefiCpuPkg/IncludeHao Wu2019-01-021-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1091 Previously, when compiling NASM source files, BaseTools did not support including files outside of the NASM source file directory. As a result, we duplicated multiple copies of "StuffRsb.inc" files in UefiCpuPkg. Those INC files contain the common logic to stuff the Return Stack Buffer and are identical. After the fix of BZ 1085: https://bugzilla.tianocore.org/show_bug.cgi?id=1085 The above support was introduced. Thus, this commit will merge all the StuffRsb.inc files in UefiCpuPkg into one file.

* UefiCpuPkg/Include/AcpiCpuData.h: Add Semaphore related Information.Eric Dong2018-10-221-1/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v3 changes: 1. Move CPU_FEATURE_DEPENDENCE_TYPE definition here from RegisterCpuFeaturesLib.h file. 2. Add Invalid type for REGISTER_TYPE which will be used in code. v2 changes: 1. Add more description about why we do this change. 2. Change structure field type from pointer to EFI_PHYSICAL_ADDRESS because it will be share between PEI and DXE. v1 Changes: In order to support semaphore related logic, add new definition for it. In a system which has multiple cores, current set register value task costs huge times. After investigation, current set MSR task costs most of the times. Current logic uses SpinLock to let set MSR task as an single thread task for all cores. Because MSR has scope attribute which may cause GP fault if multiple APs set MSR at the same time, current logic use an easiest solution (use SpinLock) to avoid this issue, but it will cost huge times. In order to fix this performance issue, new solution will set MSRs base on their scope attribute. After this, the SpinLock will not needed. Without SpinLock, new issue raised which is caused by MSR dependence. For example, MSR A depends on MSR B which means MSR A must been set after MSR B has been set. Also MSR B is package scope level and MSR A is thread scope level. If system has multiple threads, Thread 1 needs to set the thread level MSRs and thread 2 needs to set thread and package level MSRs. Set MSRs task for thread 1 and thread 2 like below: Thread 1 Thread 2 MSR B N Y MSR A Y Y If driver don't control execute MSR order, for thread 1, it will execute MSR A first, but at this time, MSR B not been executed yet by thread 2. system may trig exception at this time. In order to fix the above issue, driver introduces semaphore logic to control the MSR execute sequence. For the above case, a semaphore will be add between MSR A and B for all threads. Semaphore has scope info for it. The possible scope value is core or package. For each thread, when it meets a semaphore during it set registers, it will 1) release semaphore (+1) for each threads in this core or package(based on the scope info for this semaphore) 2) acquire semaphore (-1) for all the threads in this core or package(based on the scope info for this semaphore). With these two steps, driver can control MSR sequence. Sample code logic like below: // // First increase semaphore count by 1 for processors in this package. // for (ProcessorIndex = 0; ProcessorIndex < PackageThreadsCount ; ProcessorIndex ++) { LibReleaseSemaphore ((UINT32 *) &SemaphorePtr[PackageOffset + ProcessorIndex]); } // // Second, check whether the count has reach the check number. // for (ProcessorIndex = 0; ProcessorIndex < ValidApCount; ProcessorIndex ++) { LibWaitForSemaphore (&SemaphorePtr[ApOffset]); } Platform Requirement: 1. This change requires register MSR setting base on MSR scope info. If still register MSR for all threads, exception may raised. Known limitation: 1. Current CpuFeatures driver supports DXE instance and PEI instance. But semaphore logic requires Aps execute in async mode which is not supported by PEI driver. So CpuFeature PEI instance not works after this change. We plan to support async mode for PEI in phase 2 for this task.
