- This should allow drivers to recieve post submission events for X<->opengl synchronisation. - Lacking a testcase, i'm open to suggestion how to do it better. - The idea is: - driver recieves event - driver creates personal identification and inserts marker into X fifo. - when something wants to use an X pixmap, it checks if something is pending. - If so, it synchronizes the 2nd fifo using the initial identification. - Driver is not required to use interrupt based systems (price too high). - Lower latency is ofcource better. - If this is somehow unusable for you, then come up with improvements. - For that reason i wouldn't consider the api fixed for the moment.
