Is FreeBSD compatible wih the Intel Arc GPU's and others?

Will it work? I've heard that the Intel Arc B580 has a bunch of bugs, so will it be compatible with FreeBSD?
 
So, 15-RELEASE is out with Linux 6.6 DRM.
Is anyone running a B580, Xorg/3D accel/desktop/videos, does it all work normal? I don't care about Unreal Engine 5 woes or whatnot.
 
I do own a B580. I have not tested it under FreeBSD yet. As far as I know it should work with DRM 6.6 under 15.

If you can figure out which Linux kernel version supports your Intel Arc video card, you can figure out which version of the DRM driver you would need.

That would be 6.6
 
I also have a B580. What exactly should I do to get it working on FreeBSD 15.0: just install this?

FreshPorts -- graphics/drm-66-kmod: Direct Rendering Manager GPU drivers

amdgpu, i915, and radeon DRM drivers modules. Currently corresponding to Linux 6.6 DRM. This version is for FreeBSD 15 1500031 and above.

How do you test that it's working afterwards. I tried getting it to work on an Ubuntu 25 a while ago and failed. I would try to run some program (maybe it was opencl?) that would basically ls the stats for GPU. Core dump/error every time in that case

Should I test soon and report back (once given instructions on what a good sanity test would be) or will others post a report and guide on this soon?

- install Xorg and friends.
- try startx. Do you get a working X environment? With correct resolution, colors, etc.? If so you passed the first test.
Then you move on to more advanced testing; accelerated graphics and all that stuff.
 
It shouldn't be, as far as I know.
I ordered a B570, but it will take 20 days to arrive.

Edit : don't know why I thought 30eur less for cheaper model is good. Canceled that, ordered B580. And it will arrive shortly.
 
Funnily enough I did have a B580 card laying around, but I was missing a machine to put it into. So a week or two ago I ordered the machine, recently put it together, and today install FreeBSD 15.0-release on it, and upgraded to 15.0-release-p2

root@kg-core3:~ # freebsd-version -ku

15.0-RELEASE-p2

tested with Xorg and drm-latest-kmod (I also tested drm-66-kmod). Unfortunately, it doesn't work. /var/log/Xorg.0.log output

linux is enabled, i915kms loaded, but it doesn't work.
if I install xf86-video-scfb Xorg works, but the resolution is wrong (800x600) - my monitor has 1920x1200 resolution.

SCFB is tied to GOP resolution on UEFI installations.
Checkout gop list from loader prompt.
These resolutions are what you can set the framebuffer to in /boot/loader.conf.
#kern.vt.fb.default_mode="1366x768"

With SCFB used these settings also set your Xorg resolution. Check xrandr. Notice only one resolution available. The GOP one.

With i915kms you can have different resolutions on console and Xorg.
 
All that is gibberish for an add in card. The GOP stuff is in BIOS for the Integrated GPU not an add in card.

I am not sure how the resolutions are presented to BIOS for an add in card. I believe its called an OptionROM.
What happens when two video devices are present. Why is add-in card vgapci0 and integrated vgapci1.
You would think the opposite. Integrated devices usually have a lower pci bus address.

Thanks - I had forgotten about that. gop list shows a range of modes, and gop get showed that mode 2 (800x600x32) was selected. Doing gop set 0 (mode 0 is 1920x1200x32) got me a high resolution console (framebuffer) and then scfb works in native resolution.
