[edk2-devel] [Patch V2 0/2] Change the usage of input parameter ProcessorNumber in MpInitLibGetProcessorInfo() of MpInitLibUp

Posted by duntan 3 months, 3 weeks ago

In the V2 patch set:
In "set EXTENDED_PROCESSOR_INFORMATION to 0", set EXTENDED_PROCESSOR_INFORMATION to 0 in API MpInitLibGetProcessorInfo() of MpInitLibUp. This commit use ZeroMem() to set all fileds in output EFI_PROCESSOR_INFORMATION to 0 before StatusFlag field is reassigned.

In "Check lower 24 bits of ProcessorNumber", use BIT24 instead of CPU_V2_EXTENDED_TOPOLOGY to clearly tell that processor number only occupies the lower 24 bits.

Dun Tan (2):
  UefiCpuPkg: set EXTENDED_PROCESSOR_INFORMATION to 0
  UefiCpuPkg: Check lower 24 bits of ProcessorNumber
