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?

There's a chance this might not be related to PRIME I've tested this on another system that uses a Radeon 4200 (I know it doesn't work with the R600 backend yet) The interesting thing was when X was running I got: ./math-int rotl 4096 23 8 radeon: Failed to get PCI ID, error number -13 There are 1 platforms. clGetDeviceIDs() failed: CL_DEVICE_NOT_FOUND When I stopped X I got: ./math-int rotl 4096 23 8 There are 1 platforms. There are 1 GPU devices. clCreateContext() succeeded. clCreateCommandQueue() succeeded. Failed to open file: rotl.cl
Both tests were run via ssh so it seems the issue only appears when X is the active VT

This should work now if you enable rendernodes in the kernel. You can do this by adding drm.rnodes=1 you your kernel command line. The oldest kernel that supports rendernodes is 3.12. Please re-open if you are still having issues.
