our code is currently available in the intel-batchbuffer branch of the
xf86-video-intel driver.
-Results
+## Results
The current results can be summarized as follows. Here we are showing
the performance difference of the upstream "master" branch of the
Speedup compared to XAA
- Operation EXA (master) EXA (intel-batchbuffer)
- -------- ------------ -----------------------
- aa10text .3 0.6
- Blend 9.4 101.6
- .5 scale 7.4 34.3
- 2x scale 23.5 200.3
- General scale 20.2 946.1

shows the incidental improvements we achieved while looking closely
only at text performance.
+## Future Work
+
We are currently in the process of merging this work into the master
branch of the upstream Intel driver and plan for it to be part of the
upcoming Intel driver release scheduled for June 2008.
+
+Beyond that, we plan to add support for hardware-accelerated
+gradients, trapezoid rasterization, and perhaps polygon
+rasterization. Obviously there's similar EXA acceleration work needed
+for other drivers as well. Please come join us in the fun!
