    Phoronix: Kalray Posts Initial Patches For Bringing Up Linux On Their KV3-1 "Coolidge" DPU SoC

    While back in 2018 when the C-SKY architecture was merged to the Linux kernel it was talked about possibly being the last new CPU arch/port to be mainlined given the growing success of RISC-V even back then, it looks like that upstream kernel developer belief might not hold true. France-based Kalray that focuses on high-performance, data-centric computing from cloud to edge posted their initial Linux kernel patches today for their "KVX" kernel port to get the kernel running on their MPPA3-80 "Coolidge" DPU SoC with the KV3-1 CPU architecture...

    Huh. That’s interesting.

      Reminds me a little of both Elbrus[1] and Tachyum[2], though probably not as sophisticated as either.

      Kalray seems to have the basic formula right for doing DSP-type compute. However, pure VLIW has significant deficits for general-purpose compute. Do we really need another DSP-type core? Also, I wonder what process node it's on, because the cited clock speed is pretty low for anything modern.

      Perhaps they've lined up some fairly safe contracts with the French government. These days, it makes sense to maintain your own domestic compute capability.
