[Dri-users] G400+DRI: The story continues

[Mike M. <mac...@ya...>]

THE STORY CONTINUES

I finally got the DRI working, thank you Homme, your
help made me recompile the whole DRI tree and
installing it with the symbolic
links. Unreal-Tournament works (Very very FAST),
YAHOO!!!.

But there's still one annoying problem, after about
3/6 minuts while playing UT the X server just freezes,
I can still access my computer remotely to kill the X
process and reboot my computer so it's not totally
locked.
I think X or UT is trying to restart libGL.1.2 on the
fly after some minutes.

This is what I did to get DRI for MGA working:
- Downloaded the latest Xfree DRI from
FTP://dri.sourceforge.net/pub/dri
- Downloaded Kernel 2.4.0 test8 + prepatch3 form
www.kernel.org
- UN-tarred the kernel and applied the patch
        - Compiled the kernel with AGPGART enabled for
my chip set
- UN-tarred Xfree DRI and followed the instructions on
the DRI project site
        - Make World
        - Make Install (I choosed /bin/X11R6-DRI as
project root)
        - Compiled and installed the kernel driver
mga.o (can be compiled separate)
        (from:
/programs/Xserver/hw/xfree4/os-support/linux/drm/kernel)
        (to: /lib/modules/XX/kernel/drivers/char/drm)
        - added 'usr/X11R6-DRI/lib' in
'/etc/ld.so.conf'
above 'usr/X11R6/lib'
        - did 'ldconfig' to search and cache for the
new
libraries
        (this prevents the message 'DRM 2.XX expected
but DRM
1.0.1 installed')
        - I didn't made the symbolic links, I only
copied
mga_drv.o and mga_dri.o
        (from:
/programs/Xserver/hw/xfree4/drivers/mga/)
        ("mga_drv.o" to:
/usr/X11R6/lib/modules/drivers)
        ("mga_dri.o" to:
/usr/X11R6/lib/modules/dri/mga_dri.so) <- mga_dri.o
- Then I started the xserver with "startx" <-duh
- I tested if DRI was working as followed
        - cat /var/log/XFree*, if it says DRI loaded
successfully
        - ./glxinfo, if DRI is enabled 
        (got it from dri.sourceforge.net on the
resource
page)
        - ./gears, if DRI was working
        (MGA's performance is normally more than
700fps with
DRI enabled
        it's about 100 with DRI disabled)
        - then the big thing "Unreal-Tournament"

I hope this will help!!!

I can't explain what I did further, my problem now is
that Unreal freezes in about 6 minutes of playing.

Questions:
- Someone had a simmilair problem?
- Are the plans for DRI enabled in XFree out of the
box?
- may be, some tips to improve performance :) ? and
the performance for unreal?

Things I noticed:
- I noticed, since my DRI is working properly (except
the thing with UT) that
the QT and GTK widgets are drawed correctly
- When I copied the mga.o, the mga_dri.o and the
mga_drv.o drivers to there
appropiate directories (without installing the whole
DRI-CVS to /usr/X11R6-DRI), XFree runned with the
message DRI was enabled sucessfully, but when I runned
"glxinfo" it said DRI was disabled (and it was).
- When the system freezes, it is not totally locked, I
can still access my system remotely. (not something
new)

Again, TNX Homme, I hope you or someboody else can
help me with the UT problem. I also hope my
instructions how I installed XFree with MGA DRI
enabled will help others. I know, I know a lot of
hoping : \

Thank you,

Mikey Machuidel :)
