broadcom aarm on the pi5 doesn't support pcie atomics which rdna userspace uses through kfd kernelspace drivers for queues. last hope for the pi before switching back to darwin or proper linux is hacking resizable bar for tinygrad's am pciiface.

github.com/raspberrypi/linux… patchwork.kernel.org/project… seem promising. tinygrad's userspace driver with AMD_IFACE=PCI when writing to sysfs (/sys/bus/pci/devices/0001:03:00.0/resource0_resize) receives an ENOSPC at the moment. need to rebuild the kernel with these patches.
