I have AMD A10-7870K CPU with R7 GPU. I have setup the system to use amdgpu instead of radeon. The kernel module is loaded properly. I blacklisted radeon module by putting 'blacklist radeon' into /etc/modprobe.d/blacklist-radeon.conf and added 'amdgpu' into /etc/initramfs-tools/modules. Then ran sudo update-initramfs -u

Yet, the radeon module keeps getting loaded and I don't know why...

root@ubuntu:~# lsmod |grep -e radeon -e amdgpu
amdgpu                987136  0
radeon               1515520  3
i2c_algo_bit           16384  2 amdgpu,radeon
ttm                    94208  2 amdgpu,radeon
drm_kms_helper        155648  2 amdgpu,radeon
drm                   364544  7 ttm,drm_kms_helper,amdgpu,radeon
root@ubuntu:~#

At /etc/X11/xorg.conf.d/20-amdgpu.conf I have

Section "Device"
    Identifier "AMD"
    Driver "amdgpu"
EndSection

However at Xorg.0.log I see:

[    17.774] (II) [KMS] Kernel modesetting enabled.
[    17.774] (EE) AMDGPU(0): amdgpu_device_initialize failed
[    17.774] (II) [KMS] Kernel modesetting enabled.
[    17.774] (EE) AMDGPU(G0): amdgpu_device_initialize failed
[    17.774] (II) [KMS] Kernel modesetting enabled.
[    17.774] (EE) AMDGPU(1): amdgpu_device_initialize failed

[    17.775] (II) UnloadModule: "amdgpu"
[    17.775] (EE) Device(s) detected, but none match those in the config file.

So the questions are:

  1. Isn't this suppose to work on this processor? I read the AMDGPU driver supports Sea Islands GCN GPU.

  2. The system is working seemingly fine. X is starting and working. How can I check which graphics driver X is using?

  3. How do I fix the amdpgu_device_initialize failed messages?

Thanks!

UPDATE:

According to user experiences A10-7870K should work fine with AMDGPU-PRO https://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/amd-linux/873464-amdgpu-pro-beta-2-driver-is-playing-nicely-on-ubuntu-16-04-with-the-r9-fury?p=874788#post874788 Not that I could install it, it gives some dependency errors. I think it may help if I can install amdgpu-pro but it seems impossible! The error below is from amdgpu-pro-16.60-379184

The following packages have unmet dependencies:

Now I have also made a question at AMD forums for this driver installation failure: https://community.amd.com/message/2784212

Just keep in mind that AMD graphics drivers are a mess in 16.04+. – Android Dev Mar 4 '17 at 2:43

@AndroidDev No they aren't. You just can't use fglrx in newer kernel and Xorg versions. – dobey Mar 4 '17 at 2:48
    
I don't think amdgpu supports integrated graphics in the APUs, but only discrete cards, for the time being, at least, based on support.amd.com/en-us/kb-articles/Pages/… – dobey Mar 4 '17 at 2:58
    
That is for amdgpu-pro but I already found some forum entries where people said they got amdgpu-pro working with my processor (updated my post). I would like to install amdgpu-pro drivers but I am getting dependency erros. I don't understand how other people are installing them! – yurtesen Mar 4 '17 at 3:31
    
@dobey If they weren't a mess, then they'd work just fine OOTB like Nouveau does... – Android Dev Mar 4 '17 at 22:22

I solved the AMDGPU-PRO installation problem. Caused by Linux/Ubuntu after all ( and people keep blaming AMD for every problem :p ). When I updated from 14.04 to 16.04, the upgrade process seem to have left some old GCC packages behind and they were causing the problem.

I traced what apt-get does by using apt-get -o Debug::pkgProblemResolver=yes install libc6:i386

After I saw some 14.04 references in the output. I found out that updater left some GCC stuff behind from 14.04

I had to download the xenial versions from here:

http://packages.ubuntu.com/xenial/amd64/gcc-6-base/download
http://packages.ubuntu.com/xenial/amd64/libgcc1/download

Then it was just a matter of uninstalling old 14.04 versions and installing 16.04 versions

# dpkg --force-depends -r libgcc1 gcc-6-base
# dpkg -i gcc-6-base_6.0.1-0ubuntu1_amd64.deb
# dpkg -i libgcc1_6.0.1-0ubuntu1_amd64.deb

AMDGPU-PRO installer was able to install packages properly. I hope this helps to somebody who finds this post! I found some other threads in forums where people had similar problems.

Now, the radeon module is not loaded anymore, only amdgpu module is loaded. I was getting 300fps earlier with glxgears and it is 5000+fps (it may be low because I underclocked the internal gpu but shows things are working). Clinfo finds the GPU, so OpenCL is working.

I had to keep /etc/modprobe.d/blacklist-radeon.conf which had blacklist radeon line. But I didn't need amdgpu line in /etc/initramfs-tools/modules

Now glxinfo shows AMD.

server glx vendor string: AMD
...
client glx vendor string: AMD
...
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon Graphics

Before xorg log showed:

[ 67077.690] (II) modeset(0): [DRI2] Setup complete
[ 67077.690] (II) modeset(0): [DRI2]   DRI driver: radeonsi
[ 67077.690] (II) modeset(0): [DRI2]   VDPAU driver: radeonsi

Now Xorg log shows:

[    26.113] (II) AMDGPU(0): [DRI2] Setup complete
[    26.113] (II) AMDGPU(0): [DRI2]   DRI driver: amdgpu
[    26.113] (II) AMDGPU(0): [DRI2]   VDPAU driver: amdgpu

No more AMDGPU(0): amdgpu_device_initialize failed error messages.

While I could not get the open source AMDGPU driver work, perhaps it was because the open source driver did not support my GPU. I am happy now that the AMD's driver is supporting it and everything is working. So I will consider this issue closed.

Thanks for all the responses!

Thinking whether your answer would be relevant to 16.04 fresh installation. Even fresh installation of 16.04 also have this problem. – ankit7540 Mar 6 '17 at 0:41
    
What problem exactly? Did you make a question? Post it's link please. – yurtesen Mar 6 '17 at 2:32
    
Here is the question : askubuntu.com/questions/880011/… The issue is there whether I overclock or not. – ankit7540 Mar 6 '17 at 6:25
    
Your issue seems to be totally unrelated :) – yurtesen Mar 6 '17 at 6:32
    
the fps you mention of 300 seems to be with vsync turned on. Try again with command: vblank_mode=0 glxgears – Leder Apr 16 '17 at 21:34

In order to blacklist radeon you have to add it to the conf file and then issue the command:

sudo update-initramfs -u

I did that of course, it was implied. I just forgot to write that I did that... – yurtesen Apr 16 '17 at 21:11
    
OK, just for reference – Leder Apr 16 '17 at 21:31

I had the same problem with fresh install. Try adding the i386 architecture:

sudo dpkg --add-architecture i386

Then try the setup again.
