+The Intel Arc B580 is Intel's second generation standalone graphics card, in the 'Battlemage' series. The Xe driver has improved a bit since the first generation 'Archimedes' cards, but is still a little rough.
+
+Physically, it requires a x16 PCIe socket. You will need to supply about 225W to the card directly through it's two 8-pin PCIe power plugs.
+
+### Xe Open Source Driver
+
+To get the i915 driver loaded, you have to [recompile the Linux kernel for Pi OS](https://github.com/geerlingguy/raspberry-pi-pcie-devices/tree/master/extras/cross-compile) on the 6.15 branch (`rpi-6.15.y`) or later.
+
+Go to `Device Drivers` > `Graphics support` on the `menuconfig` step, and select the `Xe` driver to install.
+
+Before compiling the kernel, run `make menuconfig` and set:
+
+  1. Device Drivers > Graphics support > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) > Intel Xe Graphics
+  1. Device Drivers > Graphics support > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) > Intel Xe Graphics > Force probe xe for selected Intel hardware IDs > `*` (enter `*` manually for the value)
+
+There are a few other tweaks that need to be made to get this card to output a signal and work with Vulkan, OpenGL, etc. on a Pi.
+
+See the linked GitHub issue for more details.
