> Maybe Im being a bit cynical. If Apple, Intel, AMD, NVIDIA, Arm, Qualcomm, etc. would all contribute to open source to make everything work on all their devices with good perf, then that would be very good for all users. Expecting AMD to make open source contributions to improve software on Apple's hardware or Arm GPUs is "naive", not cynical. It would be like expecting Tesla to go to VW and help them improve their combustion engines for free.
