@P33M - Looking back at https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/695#issuecomment-2688386017 — I have manually applied the [upstream patch](https://patchwork.kernel.org/project/linux-pci/patch/[email protected]/), and rebooted. I'm trying to see if Resizeable BAR can work, and maybe if that helps...
Additionally, setting `xe.vram_bar_size=512` inside `/boot/firmware/cmdline.txt` seems to work now — I was able to skip the bar resize operations: ``` [ 5.510882] xe 0001:03:00.0: enabling device (0000 -> 0002) [...
Adding on more debug output... here's with `drm.debug=0xe`: ``` [ 4.971307] xe 0001:03:00.0: [drm:drm_dbg_printer.constprop.0 [xe]] i915 display info: rawclk rate: 38400 kHz [ 4.971404] xe 0001:03:00.0: [drm:intel_power_well_disable [xe]] disabling PW_D...

Setup steps I've taken so far: 1. Flash Pi OS to a CM5 with eMMC (haven't tested alternative boot methods yet) 2. Boot the CM5 3. Enable SPI: `sudo raspi-config...

After doing that, recompiling the kernel, etc. I have the extra interfaces showing up — though the Pi's built in `eth0` interface doesn't seem to get an address through the...
However, when I try running the commands to set up the switch as a dumb layer 2 switch, I get: ``` $ sudo ip link del br0 Cannot find device...
After going through all the instructions from @julianstj1 (listed a few comments earlier), I _believe_ I have the switch set up as a transparent clock finally, with hardware forwarding. Next...
