[WIP] riscv64-musl port

[leahneukirchen]

This is the beginning of a port of Void to riscv64-musl.
musl supports RISC-V as of 1.1.23.

• base-devel
• base-system
• chroot tested on Fedora in QEMU
• linux5.2
• running directly on QEMU
• running on hardware (I don't have any...)

Feel free to contribute! Having access to a bulk build would be very helpful (Debian has ~10% fallout).

[maciozo]

Know of any cheap RV64 hardware capable of running Linux? The HiFive Unleashed is rather expensive :/

[leahneukirchen]

Nope, I don't have any either. But qemu is reasonably fast actually.

Maybe this is an alternative?

Only issue with that is that the K210 only has 6MiB of general purpose memory - Linux would probably struggle.

[Mostly-BSD]

HiFive Rev B is 60$. https://www.crowdsupply.com/sifive/hifive1-rev-b#products-top

HiFive Rev B is 60$. https://www.crowdsupply.com/sifive/hifive1-rev-b#products-top

But it only has 16KiB of memory.

[leahneukirchen]

FTR I will pick up this project again in March when I get a SiFive Unmatched board.

[Anachron]

You'll probably benefit from the new cross build-helper.

Fingers crossed the Unmatched will be shipped on time.

[advancedwebdeveloper]

I might be interested to test on Qemu

[HadetTheUndying]

I'm interested helping contribute to this as soon as I get my hands on some hardware as well. I've applied for the BeagleV and intend to pick up the HiFive Unmatched. I already the components for my Unmatched build ready other than the board on hand.

Thought this might be interesing https://arstechnica.com/gadgets/2021/06/sifives-brand-new-p550-is-one-of-the-worlds-fastest-risc-v-cpus/

@leahneukirchen ooi, how did that go, is there an update here?

[leahneukirchen]

WIP branch is https://github.com/leahneukirchen/void-packages/tree/riscv-glibc but the machine is really slow which killed my motivation to do large builds.

Main blocker for upstreaming is leahneukirchen@178cead

[jailbird777]

I'm interesting in helping out with this. I have a Sipeed Lichee RV to play with. It's currently running Debian and I'd love to "fix" that :).

Looking to cross-compile, of course.

[leahneukirchen]

The libatomic thing is still a blocker I think.

[jailbird777]

And upstream isn't liking that hack?

[leahneukirchen]

No, it's just a packaging decision we need to make.

[JamiKettunen]

@leahneukirchen Are you planning to work on this still? I might get a VisionFive 2, so I'd indeed be rather interested in keeping this PR up-to-date and alive ^^

[leahneukirchen]

Long term, yes. Waiting for faster hardware though.

[Anachron]

Maybe someone has a PineTab2 V and can get Void Linux running?

I would be buying the tablet if it runs Void.

@leahneukirchen I am guessing you reopened this as you continue to work on this?

[leahneukirchen]

Yes, I got a VisionFive 2.

[Anachron]

Anybody heard of the https://sipeed.com/licheepi4a?

I am thinking about either getting one or even the cluster..

[leahneukirchen]

I decided against getting one, but I have a $20 voucher I could pass on if you wanna get one (not sure I can transfer it...).

[sug0]

it's also possible to apply for developer boards: https://riscv.org/risc-v-developer-boards/details/

I was waiting for the Milk-V Meles as it's based on the same SoC but is cheaper $99/$139 for 8/16GB, as opposed to $119/$179 for Lichee Pi. Meles does not have eMMC included so otherwise they seem pretty equivalent. Now that I rechecked it thanks to you and found that Meles is cheaper because it doesn't have eMMC, I'll probably go with Lichee Pi. But not now because today I'm buying a 2TB external HDD.

Plus I'll also have time for stocks to arrive in my country because the shipping costs are about $100 on AliExpress.

Edit: There's also the Beagle-V Ahead based on the TH1520.

[blacklightpy]

it's also possible to apply for developer boards: https://riscv.org/risc-v-developer-boards/details/

VisionFive V2 is based on JH7110 which is a bit slower than the TH1520 which also comes with an NPU and faster clocked C910 cores.

Edit: But thanks @sug0 I'll apply for it since I'm also interested in trying out software support and usability with Void.

@maciozo I have a mango pi, took it for around 30 euros, it's a raspberry pi zero equivalent in performance, you might wanna check it out.

[dataCobra]

Today my VisionFive 2 Rev. 1.3B arrived and would like to participate. 🎉

Does anybody has some documentation on how to setup a basic void setup on this board with microSD?

@dataCobra I found this: https://old.reddit.com/r/voidlinux/comments/zl6odc/void_on_riscv/j05fnic/

Instructions for Debian from https://wiki.debian.org/InstallingDebianOn/StarFive/VisionFiveV2:

• Most of VisionFive V2 hardware support is merged to upstream Linux kernel;
• A Linux kernel fork with the patches applied is available at github.com/yuzibo/vf2-linux.
• Current support state could be followed at RVSpace JH7110 Upstream Status page.
• If you want to boot Debian sid image on vf2, you can refer to vf2-debian-image, which from mmdebstrap and upstream kernel with several upstream patches. (by 2023/12/27)
• An alternative option is to boot from microSD and update u-boot and firmware using flashcp command as described at RVSpace Quick Start Guide.
• You can mostly follow the instructions given for InstallingDebianOn/StarFive/VisionFiveV1.
• However, at least some u-boot versions expect uEnv.txt to be named vf2_uEnv.txt instead.

So you'll be cross-compiling the kernel and base system with the RV64 toolchain and there maybe a bunch of patches here and there. Check out yuzibo's kernel and debian images to see if you can find anything. The image seems to be built with Docker Compose.. I haven't checked much into it, but hope this helps.

[dataCobra]

Hey @blacklightpy,

thank you for all the links.

Currently trying out the yuzibo version.

Milk-V Meles is out now. That may be a good and cost-effective board to develop for. $80, TH1520 SoC.

how about the STAR64 as well ? it costs more tho...

EDIT: afaik only armbian and NixOS are available for the board, it should prolly not be an issue as long as we're using xbps-src thanks to the chroot nature...?
