I don't know if the submitter, Alex Fan, is or plans to work on the MR, nor anyone else. From what you described, I think the best way is for you to comment on the MR, offer to help, and get it done if Alex isn't working on it, or does not reply.</div>

Dear mesa developers,</div>
<div style="font-family: Metropolis, "Clarity City", sans-serif; font-size: 14px; margin: 24px 0px;font-family: Metropolis, "Clarity City", sans-serif; font-size: 14px; margin: 24px 0px;">

I am trying to run mesa with llvmpipe on a RISC-V platform, without success. This is needed in order to get some performance figures for the RISC-V Graphics SIG.</div>
<div style="font-family: Metropolis, "Clarity City", sans-serif; font-size: 14px; margin: 24px 0px;font-family: Metropolis, "Clarity City", sans-serif; font-size: 14px; margin: 24px 0px;">

By default llvmpipe is using MCJIT and crashes on lp_build_create_jit_compiler_for_module because MCJit does not support RISC-V.</div>
<div style="font-family: Metropolis, "Clarity City", sans-serif; font-size: 14px; margin: 24px 0px;font-family: Metropolis, "Clarity City", sans-serif; font-size: 14px; margin: 24px 0px;">

Seems like MCJIT is deprecated and it is not going to accept new architectures, so llvmpipe will never run on RISC-V unless ported to ORC JIT. I see there is already a merge request for migrating llvmpipe from the deprecated MCJIT to the new ORC JIT:</div>

My understanding is that the code is good for merging in a disabled state (rather than enabled by default). However the merge is gated by the fact that a meson build option is still missing.</div>
<div style="font-family: Metropolis, "Clarity City", sans-serif; font-size: 14px; margin: 24px 0px;font-family: Metropolis, "Clarity City", sans-serif; font-size: 14px; margin: 24px 0px;">

Do the mesa developers need help with this? I could try to add the missing option myself if that helps, as this task is critical for supporting basic graphics on RISC-V. Let me know what RISC-V can do to help.</div>
