[edk2-devel] [PATCH v3 0/6] Refine SMM CPU Sync flow and abstract SmmCpuSyncLib

Posted by Wu, Jiaxin 4 months, 3 weeks ago

The series patches are to refine SMM CPU Sync flow.
After the refinement, SmmCpuSyncLib is abstracted for
any user to provide different SMM CPU Sync implementation.

Compared to V2, has following refinement & changes:
1. rename SMM_CPU_SYNC_CXT to SMM_CPU_SYNC_CONTEXT
2. rename SemBlock to SemBuffer, SemBlockPages to SemBufferSize
3. remove empty lines among the local variable declarations
4. add assert before if condition check
5. update the comments for SmmCpuSyncCheckOutCpu,
SmmCpuSyncGetArrivedCpuCount and SmmCpuSyncLockDoor.
6. remove unnecessary cxt local variable declarations.

Jiaxin Wu (6):
  UefiCpuPkg/PiSmmCpuDxeSmm: Optimize Semaphore Sync between BSP and AP
  UefiCpuPkg: Adds SmmCpuSyncLib library class
  UefiCpuPkg: Implements SmmCpuSyncLib library instance
  OvmfPkg: Specifies SmmCpuSyncLib instance
  UefiPayloadPkg: Specifies SmmCpuSyncLib instance
  UefiCpuPkg/PiSmmCpuDxeSmm: Consume SmmCpuSyncLib
