Hi @markos

Could you review the patch?

Thanks,
Leslie Zhai

markos · 2023-12-12T07:02:09Z

@xiangzhai not until lsxintrin.h is in a package in Debian for either clang or gcc. Until that happens, I cannot merge LSX support. I just tested gcc-13 and clang-17, they still don't have that file in Debian packages.

I added some review comments, which should be easy to fix until we can actually do a proper review when compiler support arrives. Thanks for your patience in this.

Move ARCH_C_FLAGS and ARCH_CXX_FLAGS to LoongArch respective cmake file. Move vpmax_loongarch to loongarch64/simd_utils.h.

Hi @markos

Thanks for your careful review!

I updated my patch as your suggestion.

Thanks,

Hi @markos

Please update to install clang-18, there is lsxintrin.h for LLVM 18 now and rust SIMD intrinsics for LoongArch merged :)

Thanks,
Leslie Zhai

Hi @xiangzhai
I will have to unbrick my 3a5000 system as I tried to flash the wrong uefi image and it doesn't boot now. I will do that in the next weeks and reconfigure the system to use a more modern compiler. If I can make it work, I will merge this PR.
Thank you again for your contribution!

Indeed, that's where I got it from, I just forgot to download the 'raw' binary. In any case, I need to figure out how to connect a JTAG or similar adaptor and upload the UEFI image using SPI. Currently it just gives a constant beep and fails to do anything else -no UEFI Shell/BIOS screen or anything else.

Hi @markos

Could you try qemu system loongarch64 if your working environment was broken please?

Thanks,
Leslie Zhai

markos · 2024-03-16T09:55:21Z

Even if it builds on qemu -which is not something I have the time to do- we would not merge the PR as we would not be able to support it in our CI. It is in the immediate plans to either fix the system or get a new one. Just be patient please.
