Hello 9Fans, I would like to share that mips64 support of Plan 9 is currently available. The compiler and the libraries are at https://bitbucket.org/cherry9/4c And a 64-bit kernel for Loongson machine is built, at https://bitbucket.org/cherry9/plan9-loongson64 The kernel seems to work fine, and so do programs like acme and page.
The userland support is in the compiler repo instead of along with the kernel, as I hope it will be useful for not only Loongson but mips64 in general. The kernel is not 9k kernel though. It is instead a (minimal) modification from 32-bit Plan 9. The next step is probably to switch to 9k kernel. For the userland, ape is not ported yet, so a few programs don't build. Currently the kernel code is not so user-friendly: to build the kernel, it needs to bind _port64/ before /sys/src/9/port/, and in the 32-bit Loongson sources bind 2f/ to the front to use 2F drivers. A kernel image is uploaded to the download page of the repo. Hope this is useful. Thanks, - cherry
