FreeBSD 15 and 9070XT

[Berko]

Hi,
I am new to FreeBSD and have console and wifi working using the guide.
Am stuck trying to get GUI to work: https://docs.freebsd.org/en/books/handbook/x11/#x-configuration-amd
During boot up gets fatal error and crashes during GPU init.
Is the 9070XT supported yet, and if so does it require anything over and above what is mentioned in the book? If not supported would there be a timeline I can try again later?
Thank you.
Regards.

Hi Berko,

See this reply and see if it helps: https://forums.freebsd.org/threads/amdgpu-radeon-rx7600-support.101348/post-739426

Just comment out line 32 of your config and you're good to go!

Thanks for that. I had no luck getting 9070XT to work but tested on another PC which has AMD RX6600 and it worked first time, am typing now from FreeBSD KDE Wayland!
Is there any workaround using a more generic driver instead of amdgpu in the meantime?

Berko, other than the vesa/scfb (and that with the caveat of no 3d acceleration), only the amdgpu driver supports recent AMD gpus, for older cards (i.e. up to GCN 1.1/1.2 mostly and depends on the gpu) you could use the radeonkms driver. Amdgpu is the only option for GCN 1.2+ (with limited supported for GCN 1.0 and 1.1),

Thanks fahrenheit. Will try the vesa/scfb driver to see how it goes and wait for amdgpu support of the 9070XT.

Berko,
I suggest trying "desktop-installer"

Hello, anything new to make 9070XT work with BSD?

It works at 1024x768 for me on FreeBSD. It's at least something, but I don't know how this works. I have no scfb in loader.conf or rc.conf. In fact it just worked because I removed any line concerning graphics drivers. OpenBSD 7.7 has ported Linux DRM version 6.12 so I guess the Radeon 9000 series is supported there. FreeBSD 15.0 is a bit more conservative on the DRM port and sits at 6.6. There is also a drm-latest which is version 6.9. That should technically already support the 9000 series but it doesn't work for me. I can install the module via pkg but when I do kldload amdgpu I get a kernel panic. Maybe we get support in 15.1.

I have no scfb in loader.conf or rc.conf.

scfb(4) is an Xorg driver, not a FreeBSD driver. It's one of two Xorg uses as a fallback if no other drivers can be detected. scfb(4) uses the EFI framebuffer, which only exist if you UEFI boot. For old school BIOS boots Xorg will fallback on the vesa(4) driver.

If you have the (Intel/AMD/NVidia) DRM driver enabled (and working) Xorg will automatically use its modesetting(4) driver.
