Intel arc b580 with xorg

[gimonchik]

I recently upgraded to intel arc b580. I have installed drm-kmod and xf86-video-intel. xorg specified the "intel" Driver in the configs, but when trying to run it, the error "no devoce found" and "no screen found" are returned. I tried specifying the BusID, but it didn't help.

You do not need x11-drivers/xf86-video-intel and/or Driver "intel". As a matter of fact, try without any configuration, it should simply detect everything automagically (and settle on the modesetting(4) driver).

Battlemage GPUs are still not supported, because there is functionality missing from DRM.

Tested Asrock B580 on 16-CURRENT snapshot of a week ago.

The Intel Arc B580 apparently requires certain bits which only Linux 6.12+ provides.

For those planning to buy an Intel Arc B580 graphics card tomorrow, you will need to be at least on the Linux 6.12 stable kernel for that's the first mainline kernel where Xe2 graphics are enabled out-of-the-box and all the necessary bits are in place. But if you don't mind a bit living on the edge, the Linux 6.13 Git kernel has even more Intel Xe2/Battlemage improvements.

FreeBSD drm-kmod in ports is currently at most version 6.9 (graphics/drm-latest-kmod), and 6.10 on Github:

LINUXKPI_VERSION_NUMBER=    61000

Considering how long it takes to port linuxkpi (6.9 was released Aug 9, 2025, and 6.10 on Jan 29. 2026), 6.12 on FreeBSD might not be ready any time soon.
