This only needs a single source value. src.A is cancelled down in
the right places.

Note that I don't have any R600 class hardware and I cannot test this.
However, AFAIR, any errors on these code paths are very obvious. If GTK+
applications render fine, the code should work correctly.

Hi,
This patch series improves performance of 2D rendering for most
workloads on Evergreen. Cayman support is also in place, but untested.
It should be quite easy to port all this to R600/R700 hardware, too.
There are three logical improvements:
1) Handling of non-overlapping same-surface Copy o
In case dst and src rectangles of a Copy operation in the same surface
don't overlap, it is safe to skip the scratch surface. This is a
common case.

Subpixel text rendering is typically done with a solid src and a
pixmap mask. Traditionally, this cannot be accelerated in a single
pass and requires two passes [1]. However, we can cheat a little
with a constant blend color.
We can use:
const.A = src.A / src.A
const.R = src.R / src.A
const.G = s
Looks like patch 3 may be too big for this list. I have pushed the
branch to https://github.com/grigorig/xf86-video-ati now.

Like Roland, I wonder if this trick couldn't be done in EXA instead of

I don't see how, EXA/XRENDER do not know about constant blend colors or
anything like it. The implementation in the backend is very simple
anyway, it should be tri
