I think the MpInitLib is necessary, because this library will serve PEI and DEX phases. In LoongArch, the MP initialization function will be  called first in the PEI phase. It will wake up all of AP, collect accurate online cores, and all APs will fill in their self information to prepare for next wakeup. The second time the MP initialization function is called will in DXE phase, usually located CpuDxe, I guess you are checked this code. This time the MP service HOB will be brought from PEI to DXE phase, and the MP protocal will be registered to prepare for service DXE phase. Like you saied, why not use the MP PPI? I think it's just that the code hasn't been added yet, and I think LoongArch will definitely need the MP PPI in the future, like memory trainning, configure APs local registers, etc. Thanks, Chao 在 2023/11/3 13:10, Ni, Ray 写道: > Chao, > MpInitLib is to avoid code duplication between CpuMpPeim and CpuDxe. > If you only need MP protocol but not MP PPI, do you still need to add > MpInitLib? > Can MpInitLib code be included in CpuDxe folder? > > Thanks, > Ray > ------------------------------------------------------------------------ > *From:* Chao Li > *Sent:* Friday, November 3, 2023 9:03 AM > *To:* devel@edk2.groups.io > *Cc:* Kinney, Michael D ; Gao, Liming > ; Liu, Zhiguang ; > Dong, Eric ; Ni, Ray ; Kumar, > Rahul R ; Gerd Hoffmann ; > Leif Lindholm ; Ard Biesheuvel > ; Abner Chang ; Daniel > Schaefer ; Sami Mujawar ; > Yao, Jiewen ; Justen, Jordan L > > *Subject:* [PATCH v1 00/29] Enable LoongArch virtual machine in edk2 > This patch set will enable LoongArch virtual machine in edk2, the new > LoongArch virtual machine is located in OvmfPkg/LoongArchVirt/, it is a > generic platform that dose not require any actual hardware. > > Patch1-Patch14: Submit the common library and driver for LoongArch > virtual machine and real hardware.

Hi Ray,

Thanks for review.


I think the MpInitLib is necessary, because this library will serve PEI and DEX phases. In LoongArch, the MP initialization function will be  called first in the PEI phase. It will wake up all of AP, collect accurate online cores, and all APs will fill in their self information to prepare for next wakeup.

The second time the MP initialization function is called will in DXE phase, usually located CpuDxe, I guess you are checked this code. This time the MP service HOB will be brought from PEI to DXE phase, and the MP protocal will be registered to prepare for service DXE phase.

Like you saied, why not use the MP PPI? I think it's just that the code hasn't been added yet, and I think LoongArch will definitely need the MP PPI in the future, like memory trainning, configure APs local registers, etc.


Thanks,
Chao

Chao,
MpInitLib is to avoid code duplication between CpuMpPeim and CpuDxe.
If you only need MP protocol but not MP PPI, do you still need to add MpInitLib?
Can MpInitLib code be included in CpuDxe folder?

Thanks,
Ray

Subject: [PATCH v1 00/29] Enable LoongArch virtual machine in edk2
 
This patch set will enable LoongArch virtual machine in edk2, the new
LoongArch virtual machine is located in OvmfPkg/LoongArchVirt/, it is a
generic platform that dose not require any actual hardware.

Patch1-Patch14: Submit the common library and driver for LoongArch
virtual machine and real hardware. Such as base help functions,
exception handel, MMU library, multiprocessor library etc.

Patch15-Patch16: Add PrePiCpuIoSize for LoongArch64. and move ArmVirtPkg
two PCDs into OvmfPkg for easier use by other architectures.

Patch17-Patch29: LoongArch virtual machine private code, include SEC and
PEI phase code, some library and drivers.

Modfied modues: MdePkg, UefiCpuPkg, EmbeddedPkg, ArmVirtPkg, OvmfPkg.
