[edk2-devel] RFC: Folder layout change in UefiCpuPkg

[edk2-devel] RFC: Folder layout change in UefiCpuPkg

[Ni, Ray]

[-- Attachment #1: Type: text/plain, Size: 1688 bytes --]

Sunil,
I would like to hear your feedback regarding locations of following RiscV64 components in UefiCpuPkg:
* UefiCpuPkg/Library/BaseRiscV64CpuExceptionHandlerLib/
* UefiCpuPkg/Library/BaseRiscV64CpuTimerLib/
* UefiCpuPkg/CpuDxeRiscV64/
* UefiCpuPkg/CpuTimerDxeRiscV64/

I would like to move them to the following new locations accordingly:
* UefiCpuPkg/Library/CpuExceptionHandlerLib/RiscV64/
* UefiCpuPkg/Library/CpuTimerLib/RiscV64/
* UefiCpuPkg/CpuDxe/RiscV64/
* UefiCpuPkg/CpuTimerDxe/RiscV64/


I want to avoid too many similar drivers in root folder, and too many libraries in Library folder.

Movement of the first 3 ones put the RiscV components under existing folders.
Movement of the last one creates the UefiCpuPkg/CpuTimerDxe folder, that could be potentially shared by other archs as well.

I raised similar comments to Chao Li who is working on LoongArch upstream.

The location movement follows the 2nd pattern defined by edk2 coding standard:
Driver's location could be:
<Feature><Phase>[<CpuArch>[<Vendor>]]
  or
<Feature><Phase>[/<CpuArch>[/<Vendor>]]

Library's location could be:

<Phase>[<CpuArch>[<Vendor>]]<LibraryClassName>[<Dependency>]

  or

<Phase><LibraryClassName>[<Dependency>]/[<CpuArch>[/<Vendor>]]



Thanks,
Ray

Hi Ray,

OK, here I come.

[Ray] INF is a good question.

[Ray] There are two options:

[Ray]    Re-use current INF file.

[Ray]    Create a new INF under LoongArch64 folder.

[Ray] If the INF content can be shared a lot between different archs. 
Single INF is better.

[Ray] I am just afraid sometimes we just mixed INF contents for 
different archs together into one INF, which makes the INF hard to read.

[Ray] So, it depends on how many contents can be shared.

I think it is almost difficult to share, because currently common files 
only work with IA32 and X86, other ARCHs cannot share files with IA32 
and X64.

Thanks,
Chao

Your proposal looks good to me except better to keep directory name as
RiscV as in other packages.

Sunil,
I am glad that you don't have concern about the direction.

"RiscV" is good to me.

Thanks!, Ray. So, shall I send patches to reorganize this?

Ray and Sunil,

I plan send two example PRs to github to  show how to deal the INFs, one 
to adjust current INF, and another PR to move the libraris to the 
current folders. I hope after these two PRs are sent we can decide what 
to do with the INF. What do you think of this plan?


Thanks,
Chao

Hi Ray and Sunil,

Sorry, I'm late, I have very busy these days.

I created two PRs in my private repo.

*Plan A:*

Moved most of LoongArch libraries and drivers to current matching 
folders, removed LoongArch private INF, adjusted common INF.

URL: https://github.com/kilaterlee/edk2/pull/8


*Plan B:*

Moved most of LoongArch libraries and drivers to current matching 
folders, keeping to use LoongArch private INF.

URL: https://github.com/kilaterlee/edk2/pull/9


After you reading these two PRs, let's discuss how to deal with INF.

I prefer plan A, it is better to use the same INF for all ARCHs and have 
only one INF per modules. I was discussed this plan with Ray and Abner, 
but it was not allowed at the time.


Thanks,
Chao

Re: [edk2-devel] RFC: Folder layout change in UefiCpuPkg

Chao,

In the plan A, CpuDxe.inf contains reference to gUefiCpuPkgTokenSpaceGuid.PcdCpuExceptionVectorBaseAddress in [Pcd] section. But I guess it’s only needed by LoongArch64. That’s why I didn’t like the common-inf idea.

But after looking at the other INF changes, I changed my mind. I think the common-inf looks good as the other INF files don’t have so much difference between LoonArch and x86.

So, I am ok with plan A. Thanks for preparing both changes for review.

Mike, Laszlo, Gerd, Abner, any comments?


Thanks,
Ray

Hi Ray and Sunil,

Sorry, I'm late, I have very busy these days.

I created two PRs in my private repo.

Plan A:

Moved most of LoongArch libraries and drivers to current matching folders, removed LoongArch private INF, adjusted common INF.

URL: https://github.com/kilaterlee/edk2/pull/8



Plan B:

Moved most of LoongArch libraries and drivers to current matching folders, keeping to use LoongArch private INF.

URL: https://github.com/kilaterlee/edk2/pull/9



After you reading these two PRs, let's discuss how to deal with INF.

I prefer plan A, it is better to use the same INF for all ARCHs and have only one INF per modules. I was discussed this plan with Ray and Abner, but it was not allowed at the time.

Thanks,
Chao

Hi Chao, That's fine with me.

Re: [edk2-devel] RFC: Folder layout change in UefiCpuPkg

[Chang, Abner via groups.io]

[AMD Official Use Only - General]

HI all,
I have no problem with the plan A, except the folder structure under CpuExecptionHandlerLib.
It has a LoongArch folder that contains the common source files for LoongArch and LoongArch64 folder under LoongArch for 64-buite architecture. This folder structure is different from other lib such as MpInitLib and CpuTimerLib.
Do you have 32-bit LoongArch? If not for now, then you probably can move the files under LoongArch to LoongArch64. Len you can a consistent folder structure for LoongArch.

Thanks
Abner

Re: [edk2-devel] RFC: Folder layout change in UefiCpuPkg

[Chao Li]

[-- Attachment #1: Type: text/plain, Size: 7229 bytes --]

Hi Abner,

The ExceptionLib is different from other libs such as Mp and Timer. 
Since ExceptionLib can provide for 32-bit service for LoongArch32 in the 
future, 64-bit private files are located in LoongArch/LoongArch64/ and 
the 32-bit will be located in LoongArch/LoongArch32, although the 32-bit 
LoongArch is not upstream yet.


Thanks,
Chao
