14.4

--- Description ---
Hi,

I have recently noticed that I was using llvmpipe instead of AMDGPU.

I am using FreeBSD 14.4-RELEASE, currently with drm-515-kmod (was happening on
drm-61-kmod too) with gpu-firmware-amd-kmod-renoir.

I was switched to 15.1-RELEASE for a short time because of this problem
preventing me from updating one of my ports, x11-wm/wayfire since wayland could
not launch without the driver but xorg is able to.

I am back to version 14 since I wanted to debug this issue and raise a bug
report.

There's also a freebsd forum thread which I've recently posted:
https://forums.freebsd.org/threads/freebsd-14-4-mesa-issue-with-drm-kmod.103356
/

I have learnt that versions of graphics/mesa-dri after v26.0.6 causes system to
fallback to llvmpipe which most desktop users wouldn't obviously want.

Tried recently released v26.2.1, too. Same issue.

I want to quote a warning from the forum thread that I don't know much about.

"amdgpu: DRM version is 3.49.0, but this driver is only compatible with 3.54.0
(kernel 6.6+) or later."

Thanks in advance.
