I was also looking into RadeonOpenCompute, but it seems Debian 10 is not a supported OS: https://rocmdocs.amd.com/en/latest/Current_Release_Notes/Current-Release-Notes.html#list-of-supported-operating-systems

I'm going to re-flash 32-bit Pi OS and see if that makes any difference.

@dtischler - Good point. Will test another card. Edit: Other card worked fine, mounted a USB 3.0 drive: ``` pi@raspberrypi:~ $ lsusb -t /: Bus 02.Port 1: Dev 1, Class=root_hub,...

Same thing under 32-bit Pi OS, unfortunately: ``` [ 0.955978] pci 0000:00:00.0: BAR 9: assigned [mem 0x600000000-0x60fffffff 64bit pref] [ 0.955997] pci 0000:00:00.0: BAR 8: no space for [mem size...

@elFarto - I just noted over in the Pi Forums issue that expanding the space to 1 GB seems to have fixed that issue: ``` ranges = ; ``` However,...

I'm now seeing the amdgpu module: ``` pi@raspberrypi:~ $ sudo modinfo amdgpu filename: /lib/modules/5.4.72-v7l-jjggpu+/kernel/drivers/gpu/drm/amd/amdgpu/amdgpu.ko license: GPL and additional rights description: AMD GPU author: AMD linux driver team ... ``` Then:...

Drat! I think the amdgpu driver only works with newer Radeons ('Southern Islands' and newer). Might have to re-recompile the kernel with the radeon driver, which according to this, supports...

Well, it's no biggie, I was just assuming that "the past 20 years" was modern here, where it's really just the past 5-10 years. Interestingly, since I had also compiled...

Rebuilding the kernel the 4th time today, this time choosing the `radeon` driver and not `amdgpu`...
