Solved No /dev/dri with drm-kmod and amdgpu driver in 13.2-RELEASE

Does anyone know how /dev/dri is created? I have the same problem as reported this thread, but with a Radeon HD8570.
I have

1. the drm-kmod package,
2. kld_list="amdgpu" in /etc/rc.conf, and
3. Section "Device"
Identifier "Card0"
Driver "amdgpu"
BusID "pci0:0:1:0"
EndSection
in /usr/local/etc/X11/xorg.conf.d/20-amdgpu.conf.

But there is no /dev/dri directory, and Xorg reports reports that it cannot open /dev/dri/card0.
How/what creates /dev/dri?
 
Maybe you need the Radeon los, not amdgpu? I don't have one of those, so I don't know.
 
This is the right driver for recent Radeon cards, like mine. The problem, as far as I can tell, is that there is no /dev/dri/card0.
 
Yes, and yes (I have xf86-video-amdgpu).

I've done a lot of experiments, upgraded packages, etc., and now something has, mysteriously, changed: X is no longer trying to open /dev/dri/card0, and it does load "amdgpu". But it still can't finish its initialization.
Please see /var/log/Xorg.0.log below.

Card seems to be supported with DRM 5.16. FreeBSD DRM driver (for 13.x) is at 5.10.

Thanks. I also finally concluded that the card is not supported, but it took a lot of work.
So, does this mean no support in FreeBSD 13.x?

And no support in 14.0 either (that has DRM 5.15). Although I do believe 5.16 is being worked on right now. So it might be supported in the near future.

Just for fun, I thought I'd try radeonkms. Surprisingly, it does work! Xfce reports the GPU as "AMD Aruba", which is not quite right, but there is noticeable graphics acceleration.
