This series patchset try to implement Mp Service protocol in UefiCpuPkg,
Jordan had implemented the startup APs code, and I try to add more
initialization code to let all APs work up, this Mp Service protocol's
implementation used EmulatorPkg/MpService for reference.
this patches works on my github:
https://github.com/ChenFanFnst/edk2/tree/cpu-mp-service
V2-V3:
1. rebase codes due to Jordan'tree updated:
https://github.com/jljusten/edk2/tree/ap-startup-example
2. add supported on Ia32 arch
3. add a new Lock to replace present SpinLock mechanisms in mutilple
processors, maybe the SpinLock mechanisms is not MP safe.
4. add function header
5. add StartupAllAPs() supported
6. add SwitchBSP() function, which is unsupported.
V1-V2:
1. do not call anything EFI API from APs.
2. add AP busy-wait for task assignment from BSP and get rid of
IPI sent mechanism.
TODO:
1) StartupThisAP/StartAllAps: when Timeout expires before AP returns
from Procedure, constrainedly terminate the executed Procedure.
Any Comment is welcome.
