I'm currently compiling with a few patches applied to try to fix the compilation problems without disabling DRM, since I'd really like to get working HDMI on my VF2.

I'll share the configuration if I'm able to get it working. Given the similarities between the two SBCs (and their respective Linux fork), it might work for the Star64 too.

The serial console stops displaying messages after these:

EFI stub: Booting Linux Kernel...
EFI stub: Loaded initrd from command line option
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services...
clk u2_dw_i2c_clk_core already disabled
clk u2_dw_i2c_clk_apb already disabled
clk u5_dw_i2c_clk_core already disabled
clk u5_dw_i2c_clk_apb already disabled

the kernel doesn't even start...

Built file locally for me: https://bpa.st/raw/SI6ZU. What log do you get with $ nix build --no-link github:NixOS/nixpkgs/9af373a61647257d16ae6062cddaa9094d24920c#pkgsCross.riscv64.libtool?

On aarch64-linux, pkgsCross.musl64.pkgsStatic.stdenv stopped being a cache hit sometime around the 26th of May. Sha eb5cd54d0 looks to be the first commit at which it is missing on the nixos-23.05 branch, but the non cross stdenv also broke/stopped being a cache hit then by the looks of things.
Does anyone have any idea why it might have gone missing and can we bring it back… ?
I would also like to have the equivalent, but from x86 to aarch64 cross.

Have you tried building it yourself or looking at the job status on Hydra?

Usually, cache misses imply a failed build.

So it does look like it builds but is missing for some other reason. What bit of the hydra infrastructure would cause it to become a cache hit ordinarily?

A successful build. Everything Hydra builds is cached.

So either Hydra lost the need to build it to build its jobs (due to job changes or failed evaluation), or your local build of the package doesn't have the same derivation as that built by Hydra.
