This week, the kernek and grub was tested. For kernel, I just did a simple test. It can be compiled correctly and the OS can boot normally. There are some "unsupported relocation" compile errors for grub, because grub currently does not support relax/b16/b21/add/sub relocations. The new LoongArch ABI gitub repo will be released in the next few days. The patch set changelog: v4 -> v5: 1. Change LOONGARCH to LoongArch. mengqinggang (6): LoongArch: include: Add support for linker relaxation. LoongArch: bfd: Add support for linker relaxation. LoongArch: opcodes: Add support for linker relaxation. LoongArch: binutils: Add support for linker relaxation. LoongArch: gas: Add support for linker relaxation.
