EnableExecuteDisable in MP_CPU_EXCHANGE_INFO is used to tell AP reset vector if enable execute disable feature on APs. This feature should be enabled before CR3 is written. Cc: Michael Kinney <michael

AsmRelocateApLoop() is used to place APs into MWAIT-loop if MonitorMwait feature is supported before hand-off to OS, or place APs into HLT-loop if MonitorMwait feature is not supported. If the current

In MpInitLibInitialize(), invoke AsmGetAddress() to get get assembly functions' entry addresses and the sizes from returned MP_ASSEMBLY_ADDRESS_MAP structure. v4: 1. Add AsmRelocateApLoop information

Firstly, get ApLoopMode from PcdCpuApLoopMode. If MonitorMwait feature is not supported, update ApLoopMode to ApHltLoop. If MonitorMwait feature is supported, get MointorFilter size by CPUID.[EAX=05H]

Initialize CPU_AP_DATA for CPU APs and add GetApState()/SetApState() helper functions to get/set AP state. Cc: Michael Kinney <michael.d.kinney@...> Cc: Feng Tian <feng.tian@...> Cc: Giri P Mudusuru <

Add CPU_VOLATILE_REGISTERS definitions for CRx and DRx required to be restored after APs received INIT IPI. Add worker functions SaveVolatileRegisters()/RestoreVolatileRegisters() used to save/restore

In PeiMpInitLib, save CPU MP Data pointer into one local Guided HOB. In DxeMpInitLib, save CPU MP Data pointer into one global variable. Add helper functions GetCpuMpData()/SaveCpuMpData(). Cc: Michae

In PeiMpInitLib, register End of PEI callback function CpuMpEndOfPeiCallback(). Cc: Michael Kinney <michael.d.kinney@...> Cc: Feng Tian <feng.tian@...> Cc: Giri P Mudusuru <giri.p.mudusuru@...> Cc: La

In DxeMpInitLib, register one period event callback function CheckAPsStatus() used to check AP Status. v3: 1. Use CamelCase for mCheckAllAPsEvent, mStopCheckAllApsStatus and CheckAndUpdateApsStatus().

In PeiMpInitLib, searching unallocated memory under in EFI_HOB_TYPE_RESOURCE_DESCRIPTOR hobs to find the memory under 1MB for AP reset vector. After End of PEI event triggered, we need to restore orig

ApCFunction() is the first C function executed from AP reset vector. When APs waken up at the first time, it will sync BSP's MTRR setting and load microcode on APs and collect APs' BIST information. W

FillExchangeInfoData() is used to fill MP_CPU_EXCHANGE_INFO date exchanged between C code and assembly code of AP reset vector. Cc: Michael Kinney <michael.d.kinney@...> Cc: Feng Tian <feng.tian@...>
