It can't be per-device, since it will need to be global across devices as the dependency chains may cross devices and we will want to choose an optimal order globally. That's my goal here, at least. At some point, the horror of scalability vs priority inversion must then be tackled. (But for now, I'd rather have priority inheritance and start from a position of good qos and build scalability on top.) -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
