I would like to know if there is a way to query an ATI/AMD device to know its serial number without looking at the stickers on the outside.

I'm particularly interested in Queriyng a Radeon HD 4890 GPU, specially using OpenCL.

Since I could have several GPUs in my system, what i want is to activate/deactivate a software lock depending on the serial number (or some other unique internal hardware identifier) on the GPUs depending on which device is going to execute a piece of a program.

So, is something like a "GPUID" available to the mentioned GPUs?
