Is Radeon RX7600 working on FreeBSD 14 ?

Hi,
As the new year is coming, I want to try another OS than Devuan GNU+Linux and FreeBSD looks promising.
I wonder if my Radeaon RX7600 GPU is working on the lastest stable branch. I tried few days ago and I had a black screen when I tried to start X server (had to reinstall Devuan instead of looking for a solution because it's my main computer).
I watched on FreeBSD Hardware Database if my GPU is working but it is not listed.
Here, is my hwinfo-probe :
hwinfo

I hope it will work because I really want to try a *BSD OS since a while.

Thanks for any anwser.
 
For AMD graphics, you will want to watch development of graphics/gpu-firmware-amd-kmod. It appears the RX7600 is Navi33 "Hotpink Bonefish" which is not currently part of that package. It seems to me that the support for AMD graphics seems to lag about a year after release date. There may be a development patch of the firmware available. The best place to check for that is with the mailing lists.

The DRM drivers (that includes both Intel and AMD graphics) are ported from Linux. DRM 5.15 corresponds with the DRM Linux driver in kernel 5.15. They're slowly working their way through the different versions and following the Linux driver. When newer versions of the driver are ported this will add support for the newer cards. It'll get there, but it takes time.

As long as the newer DRM drivers don't require changes to the LinuxKPI you will able to install it on 14.x. If drastic changes to LinuxKPI are required then it may only appear in -CURRENT.

These look to be the next steps:

If you can UEFI boot, X should be usable with scfb(4). But it won't be fast as there's no hardware acceleration in that driver.
