@6by9 > swiotlb would be using bounce buffers. There should be no need for those, which makes me wonder if you still have dtoverlay=pcie-32bit-dma still loaded from testing other cards....
@6by9 - Yeah, that's why I wound up commenting out `dtoverlay=vc4-kms-v3d` in `config.txt`; I couldn't get Xe to work at all with the built-in GPU trying to initialize. Are you...
@6by9 on Bookworm, I followed this process and Xe was happy with both my A750 and B580: https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/510#issuecomment-2605722331 So not sure if maybe the A380 could be different?
Right off the bat I ran into an issue with the @elliotweiser's command line tools role: ``` TASK [elliotweiser.osx-command-line-tools : Check the Command Line Tools package metadata] ***************************** fatal: [127.0.0.1]:...
Seems like an Ansible thing rather than a Mac thing, but I got this on core 2.19: ``` TASK [geerlingguy.mac.mas : Ensure MAS is installed.] ****************************************************************** [ERROR]: Task failed: Conditional...
Hahaha this is _absolutely_ my kind of mad. I'm actually working on a similar setup (but much less powerful, just aiming for two GPUs), using a Dolphin PCIe switch externally......
Nice, and here's testing an A4000 + A400, inspired by your setup... ``` jgeerling@cm5:~ $ nvidia-smi Sat Dec 6 13:13:39 2025 +-----------------------------------------------------------------------------------------+ | NVIDIA-SMI 580.95.05 Driver Version: 580.95.05 CUDA Version:...

Okay, working through the following... ## Check for ACS capabilities ``` $ sudo lspci -vv # Output pasted here: https://pastebin.com/1vm9geVR # It looks like the switches list ACSCap but not...
Amazing detail, couldn't ask for more haha! Thanks for posting this, I guess I can just disable the ACS on the switch then, and it should work. I'm working on...
