From 5562fe653cf88454bbf2c50f77a8b56b0dafe01b Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sat, 25 Sep 2004 07:00:15 +0000 Subject: The previous code would emit a full set of state during the first EmitState on a new cmdbuf, to ensure that state wasn't lost across UNLOCK/LOCK pairs (in the case of context switching). This was rather inefficient. Instead, after flushing a cmdbuf, mark the state as needing to be saved on unlock. Then, at the beginning of flushing a cmdbuf, if we actually have lost the context, go back and emit a new cmdbuf with the full set of state, before continuing with the cmdbuf flush. Provides a 10-15% improvement in ipers performance in my tests, along with other apps.
