Radeon 2D acceleration is implemented in two different ways. The
first method, MMIO, is used when DRI is disabled. The second
way, uses the Radeon CP engine, and is only used when DRI is
The problem though, is that the CP engine 2D code was not as
fully implemented as the MMIO code was, so earlier XFree86
releases will show a slowdown in 2D acceleration when DRI is
enabled. XFree86 4.2.0 has the situation improved slightly, but
it still isn't up to par with the MMIO code. Michel Daenzer has
implemented a bit more of the CP 2D code in DRI-CVS, which brings
the CP 2D code much closer to the level of the MMIO codepath.
4.2.0 is your best bet for stable 2D right now, while DRI-CVS
provides the latest code.
I've got a patch for 4.2.0 to add the latest code, however it was
reported as not fully working so I disabled it until I have time
to debug/troubleshoot. If anyone wants a copy of the patch, let
me know and I'll put it up on FTP.
