Made a kernel for ... and used my MNT Reform2 rk3588 to build the kernel and successfully booted to !

With 32GB of ram, 8 moderately fast arm64 cores and an NVMe disk, it seems quite viable to run Guix.

Probably still missing some functionality, but the screen, mouse, keyboard, ethernet all work, at least!

Thanks @josch for organizing those patches so nicely for the reform-debian-packages repository!

@vagrantc @josch Great work! I am still waiting for my Rk3588 order, but will try your Linux-libre-based kernel when I receive it. Can it boot to Guix? Did you notice any non-free stuff in those patches?

Have not tested booting yet, but... probably?

That is my near-term goal, anyways...

Boot tested System on the tonight!

After a few fiddly bits getting the right modules into the initrd and successfully running "guix system init" ... much to my surprise... it booted successfully on the first try!

As they say, this is not my first rodeo...

Substitute availability for aarch64 has been quite good the last couple days, otherwise I might still be compiling things!

Will push a fairly minimal example system configuration to the WIP branch tomorrow.

@vagrantc @jas The problem of "getting the right modules into initrd" is one that we also have on Debian. You can find the full list we need in the reform-tools repository at `initramfs-tools/reform.conf`.

I am well aware of the challenge on the side too, having brought up more than a few arm systems there too... but there is no comparison!

In the initrd has a hard-coded(?) list of modules loaded with insmod... In order... no attempt at dependency resolution at runtime or initrd creation. You can add modules to the list, or specify your own list entirely, which is what did for the this time.

The 90s haunt the 2020s sometimes. :)
