          Priority: medium
            Bug ID: 61416
          Assignee: mesa-dev at lists.freedesktop.org
           Summary: Clover doesn't work on a PRIME system when run under X
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: mike at fireburn.co.uk
          Hardware: Other
            Status: NEW
           Version: git
         Component: Other
           Product: Mesa

Clover doesn't find the correct device when running the simple tests when run
under X

./math-int if_ne -20 20 1     
radeon: Failed to get PCI ID, error number -13
There are 1 platforms.
clGetDeviceIDs() failed: CL_DEVICE_NOT_FOUND

When I run it from a virtual terminal (X is still running) I get:

./math-int if_ne -20 20 1
There are 1 platforms.
There are 1 GPU devices.
clCreateContext() succeeded.
clCreateCommandQueue() succeeded.
clCreateProgramWithSource() succeeded.
clBuildProgram() succeeded.
clCreateKernel() succeeded.
clCreateBuffer() succeeded.
clSetKernelArg() succeeded.
clSetKernelArg() succeeded.
clSetKernelArg() succeeded.
clEnqueueNDRangeKernel() succeeded.
clEnqueueReadBuffer() succeeded.
Pass

The above was typed manually due to the output not piping to a file - think
there are a few typos in the program

Is Clover using an environmental variable when run under X that's giving it the
wrong device name?

This is a PRIME system - sandybridge i965 with Radeon 6600M r600g
