* UefiCpuPkg/SmmCpuFeaturesLib: Skip SMBASE configurationWu, Jiaxin2023-03-061-1/+5
| | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4337 This patch is to avoid configure SMBASE if SmBase relocation has been done. If gSmmBaseHobGuid found, means SmBase info has been relocated and recorded in the SmBase array. No need to do the relocation in SmmCpuFeaturesInitializeProcessor().

* UefiCpuPkg: Add PCD to control SMRR enable & SmmFeatureControl supportWu, Jiaxin2022-08-311-0/+4
| | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3962 Two SMM variables (mSmrrSupported & mSmmFeatureControlSupported) are global variables, they control whether the SMRR and SMM Feature Control MSR will be restored respectively. To avoid the TOCTOU, add PCD to control SMRR & SmmFeatureControl enable.

| | | | | | | | | | | | | | | | | | | | | REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3218 Adds a new function called GetCpuMaxLogicalProcessorNumber() to return the number of maximum CPU logical processors (currently gUefiCpuPkgTokenSpaceGuid.PcdCpuMaxLogicalProcessorNumber). This allows the the mechanism used to retrieve the CPU maximum logical processor number to be abstracted from the logic that needs the value.

* UefiCpuPkg/SmmCpuFeaturesLib: Cleanup library constructorsMichael Kubacki2021-03-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's currently two library instances: 1. SmmCpuFeaturesLib 2. SmmCpuFeaturesLibStm There's two constructor functions: 1. SmmCpuFeaturesLibConstructor() 2. SmmCpuFeaturesLibStmConstructor() SmmCpuFeaturesLibConstructor() is called by SmmCpuFeaturesLibStmConstructor() since the functionality in that function is required by both library instances. The declaration for SmmCpuFeaturesLibConstructor() is embedded in "SmmStm.c" instead of being declared in a header file. Further, that constructor function is called by the STM specific constructor. This change moves the common code to a function called CpuFeaturesLibInitialization() which is declared in an internal library header file "CpuFeaturesLib.h". Each constructor simply calls this function to perform the common functionality. Additionally, SmmCpuFeaturesLibConstructor() is moved from SmmCpuFeaturesLibNoStm.c into a instance-specific file allowing SmmCpuFeaturesLibNoStm.c to contain no STM implementation agnostic to a particular library instance.

* UefiCpuPkg/SmmCpuFeaturesLib: Split into two filesMichael Kinney2016-12-191-1/+2
| | | | | | | | | | | | | | | | | | | | Split the default implementation of the SmmCpuFeaturesLib into two files to prepare for the addition of the STM specific SmmCpuFeaturesLib implementation. The STM specific implementation installs a different SMI entry handler and initialize the MSEG specific MSR at the end of SmmCpuFeaturesInitializeProcessor(). This patch does not introduce any functional changes to the default implementation of the SmmCpuFeaturesLib.
