lspci output: ``` 0001:01:00.0 PCI bridge: Advanced Micro Devices, Inc. [AMD/ATI] Navi 10 XL Upstream Port of PCI Express Switch (rev 24) (prog-if 00 [Normal decode]) Subsystem: Tul Corporation /...

Total system power draw while running GravityMark is around 266W, not bad (idle power around 15W, also pretty good compared to many other older graphics cards I've tested): Result:

Re-testing on kernel `rpi-6.17.y` with the [nightly Debian Trixie image](https://downloads.raspberrypi.com/nightlies/), I got everything going pretty quickly. `dmesg` output: ``` [ 5.425018] [drm] amdgpu kernel modesetting enabled. [ 5.425284] amdgpu 0001:03:00.0:...
