------- Additional Comments From [EMAIL PROTECTED] 2003-23-07 06:14 -------
Michel, about the backwards compatibility it seems not a problem. With the
same xfree/dri with Hui's patch but a different kernel (2.4.22-pre6) without
the patch, Xfree works fine but without dri. During boot it does not find the
gart driver so fallback's to soft accel for 3d. 2d performance is the same,
nothing strange. With the kernel patch but with dri unpatched the situation is
the same, no dri, nothing strange. Or you were talking about other things?
And now the x11perf results,
* without Hui's patch:
Sync time adjustment is 0.0269 msecs.

* In another system with a matrox g400max drm enabled, xfree 4.3, lots of
progs in the background and not optimized:
Sync time adjustment is 0.1122 msecs.
200 reps @ 28.3227 msec ( 35.3/sec): (xor) ShmPutImage 500x500 square
200 reps @ 28.2777 msec ( 35.4/sec): (xor) ShmPutImage 500x500 square

200 reps @ 30.5268 msec ( 32.8/sec): (xor) ShmPutImage 500x500 square
1000 trep @ 28.8416 msec ( 34.7/sec): (xor) ShmPutImage 500x500 square
Hope this helps.
(BTW, what does mean CP?)
