openSUSE is currently adding support for the LoongArch architecture, a new 64-bit architecture designed by the Chinese company Loongson, based on the MIPS architecture with custom refinements and RISC-V-like enhancements.

The architecture uses standard UEFI for booting which is fully supported by current versions of GRUB. Thus, adding support for LoongArch should be a matter of adding the EFI architecture name of LoongArch everywhere in KIWI where Arm64 support is enabled for UEFI systems.

For more information on LoongArch in openSUSE, see this mailing list post.
