One nice thing about this card: it's _exceptionally_ quiet. I only heard a little coil whine on a few scenes, and the fan only ramps up to maximum after sustained...

I am trying to get SYCL working for GPU compute (supposedly it's faster than Vulkan for Intel GPUs), following [llama.cpp's guide](https://github.com/ggml-org/llama.cpp/blob/master/docs/backend/SYCL.md#linux), but it looks like it's not seeing the B50...

After switching around a few other GPUs and setting VRAM to 8GB for medium BAR, I'm getting: ``` $ vulkaninfo --summary 'DISPLAY' environment variable not set... skipping surface info vulkaninfo:...

Some benchmarks: - glmark2-x11: 356 - vkmark: 563 - GravityMark: 69 It looks like maybe the llvmpipe on GravityMark was using CPU rendering, though :( Power usage during benchmarking with...

And here's lspci info: ``` 0001:01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM] (prog-if 00 [VGA controller]) Subsystem: Hightech Information System...

I haven't tried any Nvidia cards yet, I'm still assuming the deeper patchset is needed before those will work.

Interestingly, I was testing on a fresh Pi OS install today, and found the 7900 XT was only getting [64817](https://gravitymark.tellusim.com/report/?id=05eadce14e274c7615b230bf5837c06d95db4c9d) on PCIe Gen 2 (the default). After bumping to Gen...

@6by9 That'd be great—and I will also try to test with nouveau at some point, just wanting to finish hammering out all the AMD cards I can get my hands...

@6by9 - Testing with two different generations of Nvidia GPUs, I get a similar kernel dump on each with the `nouveau` driver: ``` [ 46.089143] nouveau 0001:01:00.0: enabling device (0000...

@RSC-Games - Going to quickly recompile here: https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/692#issuecomment-3353768036 (Edit: 48-bit addressing didn't change anything, nor did increasing `swiotlb=65535` (for 128 MB) in `cmdline.txt`.)
