Not sold. We terminated the previous context with a serialising flush; the pipe should be idle... But what about preemption, hmm? But then you have preemption between batches past the invalidate point, and so it must all be safely restored from context. So the primarily concern here is with state being overwritten by GTT updates. Still not sold. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
