Hi!
I have some very unlucky i830 chip which doesn't work well even with
reasonably modern drivers (with the release of xfree86 4.4 they are no
longer latest). The problem is that when i try to use more than
"VideoRam 8060" memory (and that's needed to use xvideo/hw cursor/dri)
all the three parts fail:
- i see some random garbage instead of hw cursor
- i get blue rectangle instead of xvideo output
- dri is not working (on deb 4.3.0-2 it uses software rendering, on
4.3.0-0pre1v4 it used to crash xfree)
- even 'x11perf -all' displays some garbage on deb 4.3.0-2 (on
4.3.0-0pre1v4 it used to crash xfree)
All the releases before deb 4.3.0-2 used to crash very often, since i
installed 4.3.0-2 it crashes seldom (once in 10-20 minutes) but now i
see much more garbage.
As i have these problems since getting new laptop three months ago i
had time to do some research on it. That's what i found so far:
Seems like the problem is in i810_drv.o<->agpgart cooperation. look
like i810_drv allocates some agp memory an then writes to some _other_
memory (btw, agpgart itself works fine, i tested it with standard
agptest and everything including maping memory/writing to
it/unmapping/remapping/checking its contents works ok).
Garbage instead of hw cursor proves this idea because i810 uses agp to
work with wh cursor and looks like this cursor really shows me some
random part of memory while xfree86 writes to some other place.
Attached to this letter are:
XFree86.0.log - log of XFree86 Version 4.3.0.1 (Debian package
4.3.0-2) w/o crash
cursor.png - what I see instead of hardware mouse cursor (for anyone
wondering how I managed to make this screenshot w/o
digital camera - its a mockup made in gimp, but it
reflects what i see very well)
glxinfo.txt - glxinfo output (note "direct rendering: No" line)
glxgears.txt - 'glxgears -info' output, 200+ fps make me think its
software :^(
xvinfo.txt - xvinfo output
xine.png - broken xvideo in action (this is xine right after startup,
when it should display its logo)
x11perf.png - 'x11perf -all' making mess on my screen
XF86Config-4 - xfree86 config used to produce all of the above
config-2.6.3 - kernel config (just for you to be sure I have agpgart
and drm support in kernel)
XFree86.0.log.old - log of [older] XFree86 Version 4.3.0.1 (Debian
4.3.0-0pre1v4) with a crash
P.S. And pleeeeeeease dont ask me to upgrade to xfree86 4.4 because:
1. What is not good for debian is not good for me ;)
2. All the major i810 changes from 4.4 (or from rc2 to be correct)
where backported to debian package AFAIK.
P.P.S. Please do not replay to my email address - it's no real (thats
the way i fight spam)
