Instead of duplicating fake devices. This requires to move amdgpu_devices.* to the common folder so they can be shared between shim and tests.

radeon_noop backend
This implements the minimum of the radeon kernel driver in order to make shader-db work. The submit ioctl is stubbed out to not execute anything.
Export MESA_LOADER_DRIVER_OVERRIDE=r300 LD_PRELOAD=$prefix/lib/libradeon_noop_drm_shim.so. (or r600 for r600-class HW)
By default, rv515 is exposed. The chip can be selected an environment
variable like RADEON_GPU_ID=CAYMAN or RADEON_GPU_ID=0x6740.
amdgpu_noop backend
This implements the minimum of the amdgpu kernel driver. The submit ioctl is stubbed out to not execute anything.
Export LD_PRELOAD=$prefix/lib/libamdgpu_noop_drm_shim.so.
To specify the device to expose, set the environment variable AMDGPU_GPU_ID
to
renoirto expose aCHIP_RENOIRdeviceravento expose aCHIP_RAVENdevicestoneyto expose aCHIP_STONEYdevice
Further names follow the CHIP_* enum values. By default, the CHIP_RENOIR
device is exposed.
To add a new device, amdgpu_devices.c needs to be modified.
amdgpu_dump_states can be used to dump the relevant states from a real
device.
