LoongArch: What we will do next
summary
LoongArch has core userspace and toolchain support upstream (binutils, GCC, glibc, gold, libffi, systemd) and basic kernel support lands around 5.19 with UEFI+ACPI in mainline 5.19 and full EFI boot flow poised for 6.1. Two incompatible worlds exist: an old “stack‑machine” relocation PSABI and a new Risk‑5‑like PSABI, plus firmware using virtual vs physical pointers. Work items: add module/loader fixes, supply rseq self‑tests, design a BPI→UEFI shim option, enable DT boot, and note no 1‑2 byte atomic instructions (possible emulation if microarchitecture assists).
