Ports/loongarch64

LoongArch

LoongArch is a RISC instruction set architecture (ISA), developed by Loongson Corporation, announced in 2020. Processors implementing this ISA are available since 2021 (Loongson 3A5000 family).

Sisyphus port

Sisyphus was ported to loongarch64 in 2023. The port is under heavy development. Currently (2023-10-31), more than 16000 packages (SRPMs), or more than 90% of all packages, are built for the port.

The port supports lp64d ABI (new world). RPM architecture is called loongarch64.
