Hi, mesa version 23.3.0-1 enabled llvmpipe on riscv64: | mesa (23.3.0-1) experimental; urgency=medium | | * New upstream release. | * rules: Drop checking for linux, now that kfreebsd support got | dropped. | * rules: Drop a duplicate special case for VULKAN_DRIVERS, and move | virtio enabling to the correct place. | * rules: LLVM supports JIT on riscv64 now, attempt to enable llvmpipe | on it. Unfortunately while mesa still builds with that change, it is now unusable on riscv64. The reason is that while LLVM indeed has support for JIT for a few releases, it only support orcjit, as mcjit is is deprecated and does not accept new architectures. Support for orcjit in mesa is being worked on, but it will take time bringing it to the same level as mcjit. There is a patch available [1] in the upstream gitlab to add support for orcjit and riscv64 in mesa. I haven't tested it yet, but it seems to be used by Arch already. In order to unbreak mesa support on riscv64, could you please either revert the change that was introduced in 23.3.0-1 or apply the patch from the merge request? Thanks Aurelien
