[Intel-gfx] [PATCH 2/2] glamor: Turn on glamor with a few glamor functions enabled.

Zhigang Gong zhigang.gong at linux.intel.com
Wed Nov 16 08:04:37 CET 2011


Integrate glamor acceleration into UXA framework. Add
necessary flushing at the following points:

1. Flush UXA batch buffer before call into glamor.
2. Flush GL operations after return from a glamor function.
3. The point we need to flush UXA batch buffer, we also
   need to flush GL operations, for example, in
   intel_flush_callback and couple of places in intel_display.c.

This commit only enables two glamor functions for
fill_spans and poly_fill_rects. Will continue to enable the
reset glamor functions soon.
