My read was this was doing non-coherent atomics on CPU memory. Atomics on GPU memory is just called migration to GPU memory, it doesn't need to be special for atomics. In that case it can free the CPU struct page completely as the data now lives in the ZONE_DEVICE page so no need for a pin, no problem with movable Jason _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
