624 * may be overly conservative for a3xx, where spoofing the gpu_id with
625 * the blob driver seems to generate identical cmdstream dumps. But
626 * on a2xx, there seem to be small differences between the GPU revs
627 * so it is probably better to actually test first on real hardware
630 * If you have a different adreno version, feel free to add it to one
631 * of the cases below and see what happens. And if it works, please
