EXA

EXA is getting close to the point where it is entirely useless on
hardware that doesn't accelerate render/composite.

On my (admittedly slow, 400Mhz) testbox, I can actually watch KDE paint
its default blue background.

Adding some logging into the EXA hooks reveals that the driver receives
millions (yes, millions) of calls of copy commands with a width and
height of 1. Yes, 1. It fills the screen with 1x1 copy commands.

Just painting KDE's plain and empty desktop screen produces a log of
nearly 3 million lines (with two log entries per copy command).

Composite is not enabled, in case that would matter.

Is anybody actually testing the stuff that goes into CVS on non-radeon
hardware?

I had EXA from about 6 weeks ago on this box before and it was nearly as
fast as XAA.
