So, the guest sends still needs to send transfer commands, and then the device can shortcut the transfer commands on the host side in case a shared mapping exists. flush commands are still needed for dirty tracking. > but we do need to do set_scanout even if the FB has not changed as > part of plane updates. Sounds like you workaround host bugs. This should not be needed with properly implemented flush. take care, Gerd _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
