Hi Ray,

I responded your comments yesterday, it looks like we have different opinions on patches 10 and 11, the rest looks fine.

Could you please consider patches 10 and 11? I think this way is probably the best solution. I hope this series to be merged as soon as passable, because the next series is depedent on this series. :)

Hope to hear back from you!


Thanks,
Chao

Hi Ray,

Thank you for reviewing my patch series very carefully.

Here are my comments:

Chao,
Thank you for your patience for preparing the new version of patches.
However, I still have following minor comments:

For patches 1~6: Reviewed-by: Ray Ni <ray.ni@intel.com>
For patches 7: can you define meaning of bits in the Attributes/Mask? It seems you are reusing the definitions defined for 7.2.3 EFI_BOOT_SERVICES.GetMemoryMap(). It's fine. But please mention that in comments. Also please use UINT64 for Attributes instead of UINTN.
Yes, I'm reusing the definitions defined for 7.2.3, I will illustrate in the comments next time. About the UINTN, I will fix it next time.
For patches 8: Can you rename PcdCpuExceptionVectorBaseAddress to PcdLoongArch64ExceptionVectorBaseAddress and put the PCD definition/reference in the DEC/INF LoongArch64 section?
OK, I will rename it next time.
For patches 9: Please make accordingly changes when you address comments for patch 7.
OK.
For patches 10, 11: Can the lib be avoided if the logic is implemented in CpuDxe driver?

This library is will be called in the PEI stage, so I can't move it under the CpuDxe.

This library is the low-level libary of CpuMmuLib, which will consume CpuMmuLIb to configure the MMU.

This way is suggested by Laszlo, who saied if CpuMmuLib can not content the configure API(high-level libary is the basecal libaray, it should not include the configure API), we can split it into two, where the hight-livel is CpuMmuLib, and the low-level is CpuMmuInitLib.

For patch 12(UefiCpuPkg: Add multiprocessor library for LoongArch64): Reviewed-by: Ray Ni <ray.ni@intel.com>
For patch 13: Please make accordingly changes when you address comments for patch 8.
OK.

Thanks,
Ray

While I can't comment on the loongarch architecture details the code
and the integration into build system looks overall sane to me.
