RX 580 Supported?

I have FreeBSD 11.1 p10 running kde4 desktop on a ryzen 7 1700. I was using a hd 7970 for my video card, and everything worked fine, i upgraded to a rx580 and now x fails to start. I could not find anything that said it is a supported card. I did not want to "-configure" because of "Video cards, monitors, and input devices are automatically detected and do not require any manual configuration. Do not create xorg.conf or run a -configure step unless automatic configuration fails. ". Is the RX580 supported or do I need to adjust something else.
Any and all assistance would be appreciated.
 
No, but you can upgrade your system to 11.2-BETA1 as I did. It works without any observable issues on my laptop with intel. BTW, kde5 is awesome.
 
Yep, you can give the BETA release a try. It will not work on 11.1-RELEASE. The beta release will be upgradable using freebsd-update(8) to the full release when the time comes.
 
Sorry, derailing the point a bit; ignoring the video card, how is the OS on the Ryzen otherwise? Any issues with stability?
If you are referring to 11.1 p10, It works fine, my only complainet is I can't get bhyve to show more than 1 cpu in my windows vm's.
 
I was pointed to "Upcoming 11.2 has graphics/drm-stable-kmod" to use my rx580. I am now on beta3 of11.2, I installed "gpu-firmware-kmod" and "drm-stable-kmod" changed my rc.conf to "kld_list="amdgpu"" on reboot x fails.
Below is my dmesg.boot from the video failing:

pestslent1 Fantastic! Thanks for opening this thread; and thanks others for your responses.
Just want to confirm this worked nicely for me. AMD Radeon RX 580, on FreeBSD 11.2-BETA3 now, installed drm-stable-kmod port, and added the following lines:

Code:
# /etc/rc.conf
kld_list="amdgpu"

# /boot/loader.conf
hw.syscons.disable="1"

rebooted and startx worked like a charm!
Thanks jmd and other FreeBSD maintainers for all your work. So excited to get FreeBSD rolling as my main desktop system!
 
Although I am an Nvidia user, I am always interested in knowing about support for the latest AMD cards, so thanks for this thread! Still got a few questions, though:

What version of Opengl are you getting with this?
Can you run the unigine benchmark?
Can you run a game like Crysis (works fine with wine/nvidia)?
Does hardware video decoding work now with the new drm?
 
3.1 Mesa 18.1.0 (mentions DRM 3.8.0)
no unigine (pkg and ports seem to be removed) glmark2 score at 1920 x 1080 =4954 (11.2 rc1 and kde5)
I do not play games, so I can't help there
I use handbrake (I think that uses cpu though) What is available in fresh ports, I am willing to try it out ( I do not know what the "new drm" is ( I know it's digital right management))
The glmark2 info shows DRM 3.8.0
 
I have an AMD RX580 card and I got the same problem like pestslent1, the amdgpu driver cannot load its firmware.
I am able to start X, however, the graphic is rendered through the modesetting driver and it's really slow. Videos are impossible to watch.
I installed FreeBSD 11.2-RC3, amdx64.
xf86-video-amdgpu and drm-stable-kmod are installed, also lang/clover for OpenCL support.

I also added as suggested above:
# /boot/loader.conf
hw.syscons.disable=1
# /etc/rc.conf
kld_list="amdgpu"

While it helps that I can start X and KDE4, X uses the wrong driver and amdgpu still has the firmware problem.

Any suggestions?

Hm, I have an idea. It seems amdgpu.ko is searching for firmware files looking like this:
amdgpu/polaris10_mc.bin: could not load firmware image, error 2

However, the modules I can find look more like this:
/boot/modules/amdgpu_polaris10_ce_bin.ko

So instead of amdgpu/polaris10_mc.bin, the driver should be trying to load amdgpu_polaris10_mc_bin, shouldn't it?
 
Will "hw.syscons.disable="1" in loader.conf still be necessary when the release version of 11.2 is released?
 
Hello pestslent1,

Could you please post your configuration? It seems you were able to resolve the issue and start Xorg with amdgpu. I tried copying your configuration but I am unable to load amdgpu. It shows errors about missing firmware (see above).
I would be very thankful if you could post the configuration that worked for you, including:
- version of amdgpu
- version of drm-stable-kmod (or drm-next-kmod)
- FreeBSD version (I believe you use 11.2-RC3, correct?)
- /boot/loader.conf
- /etc/rc.conf
- any Xorg configuration files.

If there is interest, I could post mine, but as written above - they do not work at the moment. I followed the instructions as described above and I use FreeBSD 11.2-RC3.

Thanks in advance for taking the time to share your experience.
 
I really like the idea of having a relatively powerful card in a completely open system like FreeBSD without having to install any proprietary binary blob to make it work. So I tried my luck with my RX580 and the newly released 11.2.

I'm having a comparable problem as roccobaroccoSC. A fresh install of 11.2 and using amgdpu on RX 580. Also tried an older radeon card - RX 460 with the same results. All installed from ports. Loading a plasma desktop using SDDM works fine and relatively out of the box. I modified /boot/loader.conf and /etc/rc.conf according to this thread. KDE starts, however there are no animations and moving windows around is unbearably slow. Is it a driver issue or is it a compositing issue?
Any ideas and help greatly appreciated!

PS: This machine is for experimenting purposes currently so I can provide/tweak any info/setting if required.
 
While experimenting further, I stumbled upon the following errors in dmesg:

It definitely appears that the direction of roccobaroccoSC is correct and that the firmware cannot be loaded.

I also installed graphics/mesa-demos for the kicks of it.

The output of glxinfo:

As one can see there is no mention of radeon/amd.

The output of glxgears:

247 frames in 5.0 seconds = 49.373 FPS
244 frames in 5.0 seconds = 48.615 FPS


So all points to a wrong/fallback driver being loaded. My current setup:
- graphics/drm-stable-kmod
- graphics/gpu-firmware-kmod
- x11/xorg
- x11/kde5
- x11/sddm
- sysutils/hal
- graphics/mesa-demos

It seems that there is only a small piece of the puzzle missing... Any help is greatly appreciated! Thanks in advance :)
 
Hello pestslent1,

Could you please post your configuration? It seems you were able to resolve the issue and start Xorg with amdgpu. I tried copying your configuration but I am unable to load amdgpu. It shows errors about missing firmware (see above).
I would be very thankful if you could post the configuration that worked for you, including:
- version of amdgpu
- version of drm-stable-kmod (or drm-next-kmod)
- FreeBSD version (I believe you use 11.2-RC3, correct?)
- /boot/loader.conf
- /etc/rc.conf
- any Xorg configuration files.

If there is interest, I could post mine, but as written above - they do not work at the moment. I followed the instructions as described above and I use FreeBSD 11.2-RC3.

Thanks in advance for taking the time to share your experience.

Firmware modules for the linuxkpi-based KMS components.

Amdgpu and i915 firmware files encoded in uu format to generate
loadable kernel modules. Firmware binaries originate from the
linux-firmware repository.

Thanks for the replies.

I managed to get it working. The culprit was that Xorg does not by default load the amdgpu X driver. But re-configuring it solves the problem.

So here the minimal needed setup in order to get 3D acceleration on new AMD Radeon cards in X:

Install the following ports:
* graphics/drm-stable-kmod/
* graphics/gpu-firmware-kmod/
* x11-drivers/xf86-video-amdgpu/

Re-configure X:
* Xorg -configure

Thanks for making this possible.

PS: on the topic about support and all... AMD is currently collaborating with the linux kernel developers, which is admirable. Thanks to the efforts of making that code also available to FreeBSD users, I feel, that we are past turning to the manufacturer, but should help spread the joyful news instead :)
 
UPDATE: Use latest 12.0-RELEASE. Instead of drm-next-kmod, use drm-fbsd12.0-kmod.

I succeeded in making RX 580 work with Xorg. There is a minor glitch: From time to time picture (and sound) freezes for half a second or so. It happens occasionally, but otherwise it behaves very well.
I am posting the tutorial here. Make sure to tweak for your processor and desired environment.
The example is for AMD RYZEN Threadripper CPU, RX 580 videocard with KDE 5.
Bash:
# I installed a standard 11.2-RELEASE FreeBSD on ZFS (2 mirrored nvme drives) with encryption

# After install:
# Important: Boot password is always with en_US keyboard layout!

# Support for AMD RYZEN/Threadripper CPU. Do not use on other CPUs!
