all: add freebsd/riscv64 port #53466

dmgk · 2022-06-20T18:58:39Z

This issue is intended to serve both as a proposal and to track the progress of adding the freebsd/riscv64 port.

The majority of porting work is done, there's an out-of-tree port at https://github.com/MikaelUrankar/go/tree/freebsd_riscv64 which builds and passes all run.bash tests, including cgo (tested under QEMU and on Unmatched).

@mengzhuo has graciously agreed to setup and maintain the freebsd/riscv64 builder (on SiFive Unmatched) and @MikaelUrankar has agreed to be the port maintainer.

cc @golang/freebsd @golang/riscv64 @mengzhuo @MikaelUrankar

I tried to install the prometheus node_exporter and got undefined errors from golang.org/x/sys

I think we should update golang.org/x/sys and other x/ moduels first and leave alone the Go main develope cycle.

paulzhol · 2022-06-27T07:16:44Z

I'm already updating golang.org/x/sys as part of #53280. It is indeed horribly out of date. For example Time_t on freebsd/arm is still 32-bit. It was switched to 64-bit more than 16 years ago (I guess it originates directly from the syscall package).
There ptrace constants which are defined only on the x86 arches, not available on both ARMs (because these were probably not generated on actual hosts).
I shudder to think of what state the golang.org/x/net/route is in. std still carries a hand copied if_data8 and if_msghdr8 types.

rsc · 2022-06-29T17:15:05Z

The new port policy (#53383) will require two maintainers for the port. Assuming that is accepted, is there anyone else who would be willing to be a second maintainer for freebsd/riscv64?

dmgk · 2022-07-01T12:11:44Z

Assuming nobody else volunteers, I'll be willing to be a second maintainer for the freebsd/riscv64 (can we have more than two?). I think more people will be interested when this port is closer to be merged.

mengzhuo · 2022-07-01T14:35:35Z

I want to be the third maintainer since the freebsd/riscv64 stage0 is up and ready.

I've droped CC env and it looks at Go repo after 15e2669, however there are some breaks in sub repos:

paulzhol · 2022-10-18T14:29:00Z

Could this be due to the LANG=C.UTF-8/MM_CHARSET=UTF-8 envs (but maybe with a missing /usr/share/locale/NNNN on the host)?
I do see them on freebsd/arm as well, but I explicitly had to add UTF-8 to the nanobsd build.

paulzhol · 2022-10-18T14:40:29Z

Scratch that, it looks specific to risc-v? starting from http://golang.org/cl/442796:

dmgk · 2022-10-18T20:09:45Z

Something between 4fe1971 and ddc7d2a broke x/text on riscv64. af668c6 looks relevant, I'll do git bisect but it will take some time with QEMU.

mengzhuo · 2022-10-20T11:30:47Z

NOTE: This builder will be unavailable due to kernel panic, I will try to reboot it everyday if it's down.

dmgk · 2022-10-20T11:43:09Z

@mengzhuo Thanks for reporting this. We may need to update the builder to 13.1-STABLE later when this panic is fixed.

The proposal is approved, the port is listed in go tool dist list, has a passing builder, and is mentioned in 1.20 release notes draft. Thanks and congrats on getting to this point!

Is there more that should be done here before closing this issue, or shall we do that now? (New issues can be opened to track specific known work to improve the port.)
