Has glib been ported to Plan 9? You need it since much of QEMU uses this library. I guess the code you'll need to port are timers, thread pools, signal handling, thread-local storage and pthread usage, and maybe some mmap/mprotect calls. QEMU uses a coroutines implementation which is done using makecontext()/sigsetjmp()/siglongjmp() on Linux. Other OSes have their own coroutine implementations (see coroutine-*.c). This port is a lot of work. If you want to upstream the patches, consider if you're willing to test and maintain Plan 9 support in the long term. Since QEMU is actively developed just getting a port merged isn't enough, you need to stay involved and continue maintaining it otherwise the port would bitrot/need to be dropped. Stefan
