Graphics drivers can queue the operations. When synchronisation is required, the core calls the driver's EngineSync() function to make sure all pending operations are finished. In DirectFB 1.7 there is a new task manager architecture that manages multiple async running cores with synchronisation based on the buffers being accessed, without blocking any thread at any time, like EngineSync() does for example with application threads on flipping. -- Denis Oliver Kropp DirectFB integrated media GmbH _______________________________________________ directfb-users mailing list directfb-users@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
