This is a guix channel for some riscv support package.

use https://ci.z572.online for substitute.

More development boards will be supported in the future.

We will upstream to guix what can be upstreamed to guix.

NOTE: This channel may have binary blobs etc.

how to use

add this channel add it to ~/.config/guix/channels.scm:

  (cons* (channel
          (name 'guix-riscv)
          (url "https://github.com/z572/guix-riscv-channel.git")
          (branch "main"))
         %default-channels)

Then run guix pull.

megrez

use rockos kernel

maybe support hifive-premier-p550/pine64-starpro64, but I don't have the hardware :(.

build

guix system image -s riscv64-linux --expression='(@ (riscv system images megrez) megrez-barebones-raw-image)'

/gnu/store/...-megrez-barebones-raw-image

Then you can flash the storage device and install it on megrez.

how to use amdgpu

add nonguix channel.

  (use-modules (nongnu packages linux))
  ...
  (operating-system
    (inherit megrez-barebones-os)
    (kernel-arguments
     (append (list "earlycon" "clk_ignore_unused")
             (list "initcall_blacklist=es_drm_init"
                   "pcie_port_pm=off"
                   "pcie_aspm.policy=performance"
                   "module_blacklist=pvrsrvkm")))
    (firmware (cons* linux-firmware %base-firmware))
    ...)
