I'm not sure what you guys are meaning by the "firmware", could you elaborate please? Do you mean the Open Firmware and hence the devicetree or what?Yes, I think the best way to request this is using a device-tree property. Letting the device driver request it is definitly a bad idea.
I don't follow why we need a property rather than being implied by the device's (the GPU) compatible string. Rob _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
