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

[    17.775] (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

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

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

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!

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

sudo update-initramfs -u

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

sudo dpkg --add-architecture i386

Then try the setup again.

If you don't want or need the i386 architecture, it can be fixed by skipping these packages alltogether. Simply download the latest driver, and run it's installer:

./amdgpu-pro-install

This will give you the 'unmet dependencies' error, but will set the apt repository. Now you can manually install the amd64 packages (omit vulkan-amdgpu-pro for versions <18.20):

sudo apt install amdgpu amdgpu-pro vulkan-amdgpu-pro
