Intel's Open-Source Arc Graphics Driver Not Yet Working On POWER Hardware

Besides open-source drivers being loved by Linux enthusiasts for the greater technical clarity/insight, better security with the ability to verify the driver's behavior, and better durability of the driver over the longer-term, another common open-source driver benefit is being able to get the drivers working on other CPU architectures not otherwise a focus by the upstream hardware vendor. With Intel's open-source graphics driver stack for Arc Graphics and also in the data center with the Data Center GPU Flex Series and forthcoming Ponte Vecchio, it's drawn interest from ARM, RISC-V, and POWER folks. Unfortunately at least in the case of the POWER9 hardware, the current Intel Linux graphics driver isn't yet building properly there...
