openSUSE's Open Build Service (OBS) has been running NVIDIA Grace Hopper hardware since last June, enabling native ARMv9 builds for Tumbleweed packages. The infrastructure now handles complex workloads including the Linux kernel, LLVM, GCC, Python, and Qt frameworks with good success rates. Native builds on actual silicon eliminate risks from emulated cross-compilation such as ABI mismatches and instruction scheduling errors. The post also makes a broader case for hardware vendors to donate or lend machines to OBS, framing it as a continuous automated QA benefit for vendors whose products run Linux.
