X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ced0dd0e9575c3eacd9a618c34175dde0463f393;p=mesa.git

svga: reduce looping in svga_mark_surfaces_dirty()

We don't need to loop over the max number of color buffers, just the
current number (which is usually one).

Tested with full Piglit run, Heaven 4.0, etc.
