Oh someone else is as silly as I am? I hacked this together a few months ago as well! I guess I should have written it up.
I’ve been getting llama.cpp going on various weird, old systems as I can and qwen3.c where llama.cpp has no hope. So far, I’ve tried various sparc generations (IIi, IIIi, Fujitsu M10, and an Oracle M7), a C8900 PA-RISC, some riscv boards, an Alpha 21264, POWER 9, and many X86 and ARM systems of course.
