Hi all, I am trying to use the 0x110 SERIALIZE (or 0x108 WAIT_FOR_IDLE?) command to barrier the PGRAPH commands. Unfortunately, I do not find any examples either in nouveau or gallium.
If it plays just a barrier, I guess it should work by something like (in case of m2mf): BEGIN_RING(chan, m2mf, 0x110, 1); OUT_RING(chan, 1); Otherwise, it may actually play to serialize some commands, then I would rather use as follows: BEGIN_RING(chan, m2mf, 0x110, 1); OUT_RING(chan, NUMBER_OF_FOLLOWING_COMMANDS); I have tried both approaches, and the application runs without any problems, but I am not sure if barriers have happened or not ;-) I would appreciate if anyone can tell me how to use the barrier command. Best, - Shinpei _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
