[Fwd: [Fwd: DRI and OpenGL problem with GM965]] - Problem solved

[Svetlana Atanasova]

Hello,

    Problem is solved after compiling new version of xserver. The 
difference is that
framebuffer mapping is supported in xserver in newer version and intel 
driver uses this mapping.
In the slackware 12.0 is useed  DRI major version 5, minor version 0, 
Intel driver works properly
with major version 5, minor version 4. With minor version 0 driver-intel 
tries to use it's own mapping
that doesn't work. In slackware-current there isn't newer version of 
xserver so it must be built from source.

Hello again,

    I have found in google topic for similar problem but with nvidia drivers
http://lists.freedesktop.org/archives/nouveau/2007-August/000247.html

It's a problem with memory allocation

My strace glxinfo returns the following error:

mmap2(NULL, 6553600, PROT_READ|PROT_WRITE, MAP_SHARED, 4, 0xd0000) = -1 
EINVAL (Invalid argument)
fstat64(4, {st_mode=S_IFCHR|0666, st_rdev=makedev(226, 0), ...}) = 0
fstat64(4, {st_mode=S_IFCHR|0666, st_rdev=makedev(226, 0), ...}) = 0
close(4)                                = 0
write(2, "libGL error: drmMap of framebuff"..., 61libGL error: drmMap of 
framebuffer failed (Invalid argument)
) = 61
write(2, "libGL error: reverting to (slow)"..., 52libGL error: reverting 
to (slow) indirect rendering
) = 52

I have found this patch for nvidia:
http://bugs.freedesktop.org/attachment.cgi?id=11070&action=view

I want to adapt this patch for intel to resolve at last this memory 
conflict issue.
I can find similar memory allocations in i810_dri.c and i830_dri.c

Please help which file I have to change to move FB allocated memory.

Hello,

   sorry if this is previously discussed but I'm quite new to this list.
I have HP 6710s laptop with slackware 12.0 (kernel 2.6.22.9, xserver 
1.3.0- slack 12 default)  and I have troubles with
glx. With slackware 12.0 default driver - xf86-video-intel-2.0.0 there 
is DRI but colors
looks terrible - there are visible lines on color gradient patterns. 
With driver provided
in slackware distribution in directory /patches - 
xf86-video-intel-2.1.0  colors OK, DRI working, but when I test with GL
screensaver  X server lockups with something for insufficient free 
memory to allocate in logs I don't have these logs now.
I've downloaded the latest intel drivers from 
http://www.intellinuxgraphics.org and after compiling them I don't have DRI
I got the following error in logs:
(EE) AIGLX error: drmMap of framebuffer failed (Invalid argument)(EE) 
AIGLX: reverting to software rendering

and the following warnings (if it's helpful):

(WW) intel(0): Removed DRI frontbuffer mapping in compatibility mode.
(WW) intel(0): DRIGetDeviceInfo will report incorrect frontbuffer handle.

So I can't get my videocard working properly with any drivers, please 
help whith any ideas or patches, etc.
Thanks in advance!

Best Regards,
Svetlana
