* UefiCpuPkg/MtrrLib: MtrrLibIsMtrrSupported always return FALSE in TD-GuestMin M Xu28 hours1-0/+7
| | | | | | | | | | | | | | | | | | | | | | | Currently, TDX exposes MTRR CPUID bit to TDX VM. So based on the CPUID, the guest software components (OVMF/TDVF and guest kernel) will access MTRR MSRs. One problem for guest to use of MTRR is the change of MTRR setting needs to set CR0.CD=1, which will case #VE for TDX. For Linux kernel, there is a mechanism called SW defined MTRR introduced by the patch https://lore.kernel.org/all/20230502120931. 20719-4-jgross@suse.com/. If this is integrated for TDX guest, then Linux kernel will not access any MTRR MSRs. So we update MtrrLibIsMtrrSupported() to always return false for TD-Guest, then TDVF will not access MTRR MSRs at all.

* UefiCpuPkg/PiSmmCpuDxeSmm: Remove RestrictedMemoryAccess check for MM CPUJiaxin Wu2024-09-066-31/+46
| | | | | | | | | | | | | | The PcdCpuSmmRestrictedMemoryAccess is declared as either a dynamic or fixed PCD. It is not recommended for use in the MM CPU driver. Furthermore, IsRestrictedMemoryAccess() is only needed for SMM. Therefor, there is no need for MM to consume the PcdCpuSmmRestrictedMemoryAccess. So, this patch is to add the SMM specific file for its own functions, with the change, the dependency of the MM CPU driver on PcdCpuSmmRestrictedMemoryAccess can be removed.

* UefiCpuPkg/PiSmmCpuDxeSmm: Clean mCpuSmmRestrictedMemoryAccessJiaxin Wu2024-09-061-7/+4
| | | | | | | | | | Currently, mCpuSmmRestrictedMemoryAccess is only used by the IsRestrictedMemoryAccess(). And IsRestrictedMemoryAccess() can consume the PcdCpuSmmRestrictedMemoryAccess directly. Therefore, mCpuSmmRestrictedMemoryAccess can be cleaned to simply the code logic. Signed-off-by: Jiaxin Wu <jiaxin.wu@intel.com>
* UefiCpuPkg/PiSmmCpuDxeSmm: Update IfReadOnlyPageTableNeededJiaxin Wu2024-09-061-18/+1
| | | | | | | | | | After the 9f29fbd3, full mapping SMM page table is always created regardless the value of the PcdCpuSmmRestrictedMemoryAccess. If so, SMM PageTable Attributes can be set to ready-only since there is no need to update it. So, this patch is to remove restricted memory access check when setting the SMM PageTable attributes.

* UefiCpuPkg/PiSmmCpuDxeSmm: Correct SetPageTableAttributes func usageJiaxin Wu2024-09-062-12/+8
| | | | | | | | | | | SetPageTableAttributes() will use the IfReadOnlyPageTableNeeded() to determine whether it is necessary to set the page table itself to read-only. And IfReadOnlyPageTableNeeded() has already token into account the status of IsRestrictedMemoryAccess(). Therefore, there is no need for an additional call to IsRestrictedMemoryAccess() before calling the SetPageTableAttributes(). Signed-off-by: Jiaxin Wu <jiaxin.wu@intel.com>

* UefiCpuPkg/PiSmmCpuDxeSmm: Always save and restore CR2Jiaxin Wu2024-09-061-14/+4
| | | | | | | | | | | | | | | | | Following the commit 9f29fbd3, full mapping SMM page table is always created regardless the value of the PcdCpuSmmRestrictedMemoryAccess. Consequently, a page fault (#PF) that triggers an update to the page table occurs only when SmiProfile is enabled. Therefore, it is necessary to save and restore the CR2 register when SmiProfile is configured to be enabled. And the operation of saving and restoring CR2 is considered to be not heavy operation compared to the saving and restoring of CR3. As a result, the condition check for SmiProfile has been removed, and CR2 is now saved and restored unconditionally, without the need for additional condition checks.

* UefiCpuPkg/PiSmmCpuDxeSmm: Fix IsSmmCommBufferForbiddenAddress checkJiaxin Wu2024-09-062-1/+5
| | | | | | | | | | | | | | | | SmiPFHandler depends on the IsSmmCommBufferForbiddenAddress() to do the forbidden address check: For SMM, verifying whether an address is forbidden is necessary only when RestrictedMemoryAccess is enabled. For MM, all accessible address is recorded in the ResourceDescriptor HOB, so no need check the RestrictedMemoryAccess is enabled or not. This patch is to move RestrictedMemoryAccess check into SMM IsSmmCommBufferForbiddenAddress to align with above behavior. With the change, SmiPFHandler doesn't need to check the RestrictedMemoryAccess enable or not. Signed-off-by: Jiaxin Wu <jiaxin.wu@intel.com>

It allows certain platforms to switch to X2 APIC as early as possible and also independent on CpuFeaturePei/Dxe. The platform should switch BSP to X2 APIC mode first before the CpuMpPeim runs.

* UefiCpuPkg/PiSmmCpuDxeSmm: Simplify SMM Profile Size CalculationJiaxin Wu2024-08-284-11/+11
| | | | | | | | | | | | | | | | | | | | | | The motivation of this change is to simplify the logic in StandaloneMmIpl when allocating the memory for SMM profile data. IPL does not need to detect the CPU feature regarding MSR DS Area. That change requires the PCD value contains the MSR DS Area. So, the size of SmmProfileData will be simplified to the PcdCpuSmmProfileSize directly. mMsrDsAreaSize will be within the PcdCpuSmmProfileSize if mBtsSupported is TRUE.

| | | | | | | | | | | | | | | | | | | | | | For MM, gMmProfileDataHobGuid Memory Allocation HOB is defined to indicate SMM profile feature enabled or not. If the HOB exist, SMM profile base address and size will be returned in the HOB, so no need to consume the PcdCpuSmmProfileEnable feature PCD to check enable or disable. To achieve above purpose, Add the IsSmmProfileEnabled () function. With this change, Both MM and SMM can use the new function for SMM profile feature check.
