The attached patch disables usage of LLVM JIT on riscv64, which was causing the error I reported in comment #3.
I obtained this patch from the following Debian bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1004039 This patch, combined with the previous one, seems to work well on the Sipeed Lichee RV board. I have tested this with ubuntu-frame and a custom-built mesa-core20 snap containing the drivers built using these patches. ** Bug watch added: Debian Bug tracker #1004039 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1004039 ** Patch added: "mesa-disable-llvm-riscv64.debdiff" https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1995137/+attachment/5630389/+files/mesa-disable-llvm-riscv64.debdiff -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1995137 Title: "sun4i-drm_dri.so" is missing from libg1-mesa-dri on riscv64 Status in mesa package in Ubuntu: New Bug description: "sun4i-drm_dri.so" is needed for some RISC-V platforms such as the Allwinner D1.
