Hi!

JFYI. Также автору патча требуются тестеры с RV100.

OK, do you 'really" want some r200 numbers...;-)))

I've applied all three patches on Mesa / XFree86 DRI (the dri.freedesktop.org 
copy) CVS and fixed xc/programs/Xserver/hw/xfree86/drivers/ati/radeon_reg.h.

First:
I had NO crash during all of my tests.

Second:
I see same (?) black horizontal line corruption as Jacek. (pitch?)
But only with texture enabled.
gears, ipers, gloss, quake3-smp, UT2k3/4

Vertical/horizontal black stippeled lines (blocks) in isosurf.

But texcyl is fine.

dual Athlon MP 1900+
1 GB DDR266, CL2
r200, 64 MB

(--) RADEON(0): Chipset: "ATI Radeon 8500 QL (AGP)" (ChipID = 0x514c)
(--) RADEON(0): Linear framebuffer at 0xe8000000
(--) RADEON(0): VideoRAM: 65536 kByte (128 bit DDR SDRAM)
(II) RADEON(0): AGP card detected

Desktop: 1280x1024x24 (32)
All with AMD PM.

			window		fullscreen

640x480		198			199

1024x768		123			123

1280x1024	88			83

1280x1024 window mode was a little bit clipped (KDE window frame).
640x480 window mode _was_ ~164 fps before!!!

Even somewhat slower compared with my numbers from yesterday.

progs/demos> 7237 frames in  5.001 seconds = 1447.111 FPS
7780 frames in  5.000 seconds = 1556.000 FPS
7822 frames in  5.001 seconds = 1564.087 FPS
7790 frames in  5.000 seconds = 1558.000 FPS

without PM:

progs/demos> ./gears
9790 frames in  5.000 seconds = 1958.000 FPS
11608 frames in  5.000 seconds = 2321.600 FPS
11605 frames in  5.000 seconds = 2321.000 FPS
11603 frames in  5.000 seconds = 2320.600 FPS

I see.

gloss went from ~404 fps (with PM)

progs/demos> ./gloss
2321 frames in 5.001 seconds = 464.107 FPS
2597 frames in 5 seconds = 519.4 FPS
2605 frames in 5.001 seconds = 520.896 FPS
2591 frames in 5.001 seconds = 518.096 FPS
2610 frames in 5 seconds = 522 FPS

without PM:
progs/demos> ./gloss
2777 frames in 5 seconds = 555.4 FPS
3152 frames in 5 seconds = 630.4 FPS
3149 frames in 5 seconds = 629.8 FPS
3151 frames in 5 seconds = 630.2 FPS

doom3-demo
_playable_
640x480 window on my desktop (see above)
~27 fps

UT2k3
Not that much faster. (Not measurable.)
But was playable.

UT2k4
Much faster.
Now, playable.

Viewperf-7.1.1
~1 fps faster in most tests

But texture corruption in all tests.
Even worse when the 3D window is huge (!)
Full vertical dimension.
Maybe a pattern?
To few memory?

I have test images (ask me).

We will see;-)

GREAT stuff!
