It *looks* like incrementing the flip count for the fb passed into the routine is the right thing to do; we want to make sure the fb passed in isn't used again until its flip is complete. But maybe we're decrementing it incorrectly in the buffer exec path or allowing rendering to continue too soon? -- Jesse Barnes, Intel Open Source Technology Center _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
