Hello,

thanks to the heroic efforts of the developers who
ported amdgpu and drm-next-kmod to 11-STABLE, I was
able to get X working on a Radeon RX580 on my system:

FreeBSD monster 11.2-BETA2 FreeBSD 11.2-BETA2 #1 r334062:
Tue May 22 23:46:29 CEST 2018 root@monster:/usr/obj/usr/src/sys/GENERIC amd64

by installing:

x11-drivers/xf86-video-amdgpu
graphics/drm-next-kmod
graphics/gpu-firmware-kmod

then adding to /etc/rc.conf:

kld_list="amdgpu"

and adding myself and root to the group video, as required.

After the reboot, the default VGA console with the big chars
was replaced with a much better-looking vt console, and amdgpu
as well as the firmwares show up in kldstat:

$ kldstat

To set up X, I deleted my old xorg.conf, and added

/usr/local/etc/X11/xorg.conf.d/10-amdgpu.conf with this:

Section "Device"
    Identifier "AMD"
    Driver "amdgpu"
    Option "DRI" "3"
    Option "TearFree" "true"
EndSection

That's it.

glxinfo (from graphics/mesa-demos) reports among others:

Extended renderer info (GLX_MESA_query_renderer):

and glxgears renders at 60 FPS on my 4K LG TV, which looks about right.

What's still not working is sound output via HDMI:

$ cat /dev/sndstat
Installed devices:
pcm0: <ATI R6xx (HDMI)> (play) default
pcm1: <ATI R6xx (HDMI)> (play)
pcm2: <ATI R6xx (HDMI)> (play)
pcm3: <ATI R6xx (HDMI)> (play)
pcm4: <ATI R6xx (HDMI)> (play)
pcm5: <ATI R6xx (HDMI)> (play)
pcm6: <Realtek ALC1220 (Analog 5.1+HP/2.0)> (play/rec)
pcm7: <Realtek ALC1220 (Rear Digital)> (play)
pcm8: <Realtek ALC1220 (Front Analog Mic)> (rec)
No devices installed from userspace.

I tried setting hw.snd.default_unit from 0 to 8, but no
sound via HDMI (sound is working on the analog device though).

I didn't try switching to another HDMI port.

Any ideas?

Thanks,
-cpghost.
