Porting Guix to RISCV

Porting Guix to RISCV

[Pjotr Prins]

Anyone interested in porting GNU Mes and GNU Guix to RISCV? We can try
and purchase the hardware. We have a Polarfire running

  https://www.crowdsupply.com/microchip/polarfire-soc-icicle-kit

and there are more options coming. I am happy to support such an
initiative and buy the hardware.

I added a few RISC-V related packages to guix already:

  u-boot-qemu-riscv64
  u-boot-qemu-riscv64-smode
  u-boot-sifive-fu540
  opensbi-sifive-fu540
  opensbi-qemu-sifive-u
  linux-libre-riscv64-generic

Got as far as booting a kernel in qemu, at least. So the basic boot
infrastructure is at least partly there...

So, I guess you could count me as interested. :)


live well,

The libre-soc also supports riscv userspace, but its primary architectrue is the POWER ISA.
Therefore I propose to port guix to the POWER architecture too.

...trying not to get noticed, /me looks at their full plate (cough Mes +
ARM) and then slowly looks over shoulder...

Great!  Anyway, runing RISC-V on Guix (can I dream "the Hurd"?) is an
amazing perspective, so count me in!  Did anyone try building bootstrap
binaries for RISC-V?

Hello!

Libre-Soc it's a really interesting initiative, kudos!

There are efforts ongoing to integrate Power architecture in Guix, you 
can find the latest additions on the "wip-ppc" branch[1].

There's actually a blocking issue related to reproducibility[2].

You're welcome for any hint to try out Guix on Libre-Soc platform, would 
be awesome!

Have a happy hacking day!

Yes, I was actually able to run a 32-bit program on my Talos II.
