            Bug ID: 108760
           Summary: AMD GPU pro 18.40 doesn't work with Kabylake-g
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu-pro
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: hai.lan@intel.com

When I use AMD GPU pro 18.40 driver with kabylake-g(Vega M GPU), The display
can work but I can't enter the GUI. Everytime when I enter the password to log
into the GUI desktop, the X-window will crash. When I switch to 18.40 open
stack driver, it works OK.

Following is my environment
CPU: Intel(R) Core(TM) i7-8809G CPU
GPU: Vega M(device ID: 694c)
OS: Ubuntu 16.04
Kernel: 4.18.0-rc3
Driver: AMD 18.40 Pro driver

Please use the upstream drivers for VegaM.

Alex, Thanks a lot for your quick response! 

Hai is taking leave. I will follow up the issue when he takes leave.

Could you please be more specific about the "upstream driver" mentioned in your
comment? so we could have a try on our side.

upstream is the open stack.

Alex,

We've tried the Open Stack, the OpenGL can work. From
https://amdgpu-install.readthedocs.io/en/latest/install-overview.html, the
Vulkan component is not in the "All-Open Stack" component list, that's reason
we try Pro Stack at the beginning.

Following on the "upstream drivers for VegaM", what do you mean specifically?
We find that there are two open source drivers:

1) https://github.com/GPUOpen-Drivers/AMDVLK
2) https://www.mesa3d.org/

Is one of them the "upstream driver"?

Either should work.

Vega-M is the integrated AMD GPU in kaby lake-g CPU.
When we use mesa 18.2.2( https://www.mesa3d.org/) the GPU can work with
AMD-Open driver. But it can't work with AMD-pro driver, thanks.
