[edk2-devel] [PATCH 0/6] [RFC] Rework UefiCpuPkg
Posted by Abner Chang 2 years, 1 month ago 
https://bugzilla.tianocore.org/show_bug.cgi?id=3860

This is the project having rework on UefiCpuPkg in order to support a variety
of processor architectures. Some modules under UefiCpuPkg are required to be
abstract for the different archs.

The first step is to classify UefiCpuPkg modules to IA32 and X64 sections in
DSC file (Patch 1/6). Move the module to Common section later if more than one
archs can leverage the same module (such as Patch 3/6 for BaseUefiCpuLib).

Re: [edk2-devel] [PATCH 0/6] [RFC] Rework UefiCpuPkg
Posted by Michael D Kinney 2 years, 1 month ago 
Hi Abner,

Will OpenSBI content be needed by libs/modules outside of UefiCpuPkg?

Should OpenSBI includes be promoted to MdePkg?

I do not think the dir name "RISC-V" follows the file/dir name requirements.
The '-' should not be used.

I think there is a discussion about moving UefiCpuLib to MdePkg.

Thanks,

Mike

Edk2OpenSBILib is the wrapper library of OpenSBI, so there is module neither inside nor outside UefiCpuPkg uses OpenSBI directly. Edk2OpenSbiLib is currently used by SecCore only as it describes here:
https://github.com/tianocore/edk2-platforms/tree/master/Platform/RISC-V/PlatformPkg. 
We had designed to expose OepnSBI API in both edk2 version OpenSBI PPI and Protocol, so the answer to your question is: No, OpenSBI/Edk2OpenSbiLib is not needed by modules outside UefiCpuPkg as the design we have so far.

> 
> Should OpenSBI includes be promoted to MdePkg?
That is possible and seems reasonable to move the entire OpenSBI(Edk2OpenSbiLib) source/include to under MdePkg because there is no dependency with edk2 RISC-V header files under UefiCpuPkg. 
But one question: Shall we have OpenSBI lib under MdePkg if it is only used by UefiCpuPkg?

We had the same discussion before and '-' is valid in the file name as it defined in the coding standard. I remember we also agreed or accepted having "RISC-V' as the directory name for the modules on edk2-platforms repo. Same scenario can applied on edk2 repo.

>

Is that a serious discussion or just a verbal discussion? 😊 Any conclusion we had from the discussion?
Move UefiCpuLib to MdePkg leads the dependency with UefiCpuPkg for those architecture header files. I consider this doesn't make sense to MdePkg, right?
I would suggest still having UefiCPuPkg under UefiCpuPkg for now. Move it around one day when there is a clear decision for UefiCpuPkg comes out.

Thanks for feedbacks

Re: [edk2-devel] [PATCH 0/6] [RFC] Rework UefiCpuPkg
Posted by Abner Chang 2 years, 1 month ago 
Hi Mike,
In the v2, I moved two of OpenSBI header files to under MdePkg/Include/IndustryStadard (patch 5/8). However, it looks to me not quite proper to have those files there. Seems to keeping those files under UefiCpuPkg makes more sense.
What do you think?

Abner
