+ i965: Work around mysterious Gen4 GPU hangs with minimal state changes.
+
+ Gen4 hardware appears to GPU hang frequently when using Chromium, and
+ also when running 'glmark2 -b ideas'. Most of the error states contain
+ 3DPRIMITIVE commands in quick succession, with very few state packets
+ between them - usually VERTEX_BUFFERS/ELEMENTS and CONSTANT_BUFFER.
+
+ I trimmed an apitrace of the glmark2 hang down to two draw calls with a
+ glUniformMatrix4fv call between the two. Either draw by itself works
+ fine, but together, they hang the GPU. Removing the glUniform call
+ makes the hangs disappear. In the hardware state, this translates to
+ removing the CONSTANT_BUFFER packet between the two 3DPRIMITIVE packets.
+
+ Flushing before emitting CONSTANT_BUFFER packets also appears to make
+ the hangs disappear. I observed a slowdown in glxgears by doing it all
+ the time, so I've chosen to only do it when BRW_NEW_BATCH and
+ BRW_NEW_PSP are unset (i.e. we haven't done a CS_URB_STATE change or
+ already flushed the whole pipeline).
+
+ I'd much rather understand the problem, but at this point, I don't see
+ how we'd ever be able to track it down further. We have no real tools,
+ and the hardware people moved on years ago. I've analyzed 20+ error
+ states and read every scrap of documentation I could find.
