[Bug 1583888] [NEW] Laptop crashes when trying to run discrete AMD GPUs commands with Xenial

 

Public bug reported:

I'm trying to get an A+A (AMD integrated GPU and AMD deiscrete GPU)
device [1] to work with the open source drivers on Xenial.

lspci reports the following regarding the GPUs:

In order to use the discrete GPU, in Xenial you can prefix any command with `DRI_PRIME=1`. However, with this device, doing this crashes the device.

I tried installing a backported kernel that Alberto provided [2] and
even though the computer does not crash anymore, it still won't show
anything (but the process launched will take 100% of the CPU and cannot
be stopped nor killed, it looks...).

I tried with the following commands:

glxinfo
glxgears
DRI_PRIME=1 glxinfo
DRI_PRIME=1 glxgears

Once, I managed to get some output from the `glxinfo` command, with and
without `DRI_PRIME=1` prefix:

$ glxinfo | grep -i "opengl"
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD KAVERI (DRM 2.43.0, LLVM 3.8.0)
OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.2.0
OpenGL core profile shading language version string: 4.10
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 11.2.0
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.2.0
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00
OpenGL ES profile extensions:

$ DRI_PRIME=1 glxinfo | grep -i "opengl"
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD ICELAND (DRM 3.1.0, LLVM 3.8.0)
OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.2.0
OpenGL core profile shading language version string: 4.10
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.2.0
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

So it looks like the discrete GPU is used, but so far I couldn't really
use it to run anything 3D-demanding.

Attached is a Zip with a lot of logs, hope this will help!
