Bug Description

The package is missing the `radeonsi` driver, with the reasoning that LLVM is not implemented on the architecture:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=995618

That said, it works just fine on focal, where it is still enabled. Without this driver there's no way to use AMD graphics cards on RISC-V.

Therefore marking as fix released.

@xypron the packages you mentioned still don't include the `radeon` or `radeonsi` driver:

not going to get fixed before llvm supports JIT on riscv64

@tjaalton, but it works just fine on focal in our tests… can we not enable radeon/-si without enabling gallium at the same time? Maybe I'm simplifying things, but we're running Mir GL tests on focal with riscv64/AMD GPU just fine.

Which version of mesa on focal is that? The current backport version is from jammy and doesn't enable gallium for riscv64.

Radeonsi requires llvm.

@tjaalton it's 21.2.6-0ubuntu0.1~20.04.2 in focal:

oh right, 22.0.5 hasn't been backported yet

anyway, if llvm is enabled, it'll essentially break swrast for riscv64.. if that's a tradeoff you can live with, then okay

I suppose we may need to work with a PPA then.

@xypron what do you think?
