In clGetDeviceIDs(). The device type is a bit-field value. But Spec does not
say exactly whether masked value is allowed as input argument.

The problem is whether we should report an INVALID_DEVICE_TYPE when user
passes (CL_DEVICE_TYPE_GPU | CL_DEVICE_TYPE_DEFAULT) or other kind of mixed
device types. Beignet currently report INVALID_DEVICE_TYPE error.

Obviously piglit does not think so. It use mixed type to get available
device number.

Personally, I agree with piglit. We should NOT report INVALID_DEVICE_TYPE
for mixed device type. Any comments?

 

Thanks!
