Forget my experiments with X.org 6.9.

These modules work with puppys X.org 6.8.1.

They enable the 3D-Hardware-acelleration for a wide variety of Graficscards, so they are a "must" for people who like to play games.

******************************************************
Note if you have a Nvidia-card, use these instructions instead:

Note
For ATI-cards up to the "200"-series, there also is an experimental Dotpup of ATIs propriatary Drivers (Feedback needed!):
http://www.murga.org/~puppy/viewtopic.php?p=41155#41155

******************************************************

Download free X.org-DRI-drivers (424 kb):
http://dotpups.de/dotpups/XServer/DRI-Kernelmodules.pup

Install, then run the following command in a console after every reboot, or add this line as second line to /etc/rc.d/rc.local0

install-DRI MODULNAME

Instead of MODULNAME you must use the name of your module.
If you want to load radeon.o , use
/usr/local/install-DRI/install-DRI radeon

These modules are available:
i810.o
i830.o
i915.o
mach64.o
mga.o (Matrox)
r128.o (Rage)
radeon.o
savage.o
sis.o (not 650)
tdfx.o
via.o (note: better "unichrome-driver" available in a following message)

You also will need a "dri"-file especially for your graficscard, get it from here:
http://noforum.de/dotpups/X11R6addons/

important on Puppy1.0.7 / 1.0.8 the "Xorg-libGL/Mesa"-libraries must be installed with PupGet.
You also should install glxinfo to test if DRI is enabled:
http://www.murga.org/~puppy/download.php?id=1756

Some cards like mach64 might need this OpenGL-version instead (it already includes glxinfo): http://noforum.de/dotpups/X11R6addons/OpenGL.pup

-------------------------------------
Finally, modify your xorg.conf with an editor - in Section "Module" check that Load "dbe" and Load "glx" are there.

A truly great project! Very Happy

I have a via chipset. I followed your instructions. Below is the output of the command. I take it something is not as it should Confused

just loaded the via-module on 2 different computers with 3 different pup001 (Puppy 107 beta and final), without errors.

No idea how to help you Sad

What for a puppy do you use?

After seeing your post I got a reframe on the issue. I am using 107, but I was using bombayrockers 2.4.29-lck... I swaped back to the stock kernel/image.gz and voila the module loads Very Happy

Thank you so much for this!

I tried it with 1.0.7 and used the via driver (I have a built in savage card) I was unsuccesful - but the procedure was quite complex to follow (but I did rush it somewhat) Embarassed

- also my system is getting overloaded with stray files - so have started a new pristine pup001

The screen shots look great Smile

We need more testers - no one play games anymore?
Come on you guys - who knows Gamepup could be on its way . . . Hey wait a minute didn't we have such a project? Anyone connected a joystick to Puppy? - xorg should make that possible . . .

Cool

Lobster, what Driver is used in your xorg.conf?

If it is "via":
install the dotpup.
And install http://noforum.de/dotpups/X11R6addons/dri-via-mandrake.pup

In a console type:
/usr/local/install-DRI/install-DRI via

Restart X.
Run "glxinfo" to test if it works(it should say "DRI: yes").

As you can play Descent2 I assume your /etc/X11/xorg.conf includes these 2 lines in Section "Module":

As I reported in your other post "ATI-3D-Drivers(old cards) / X.org 6.9 RC1" http://www.murga.org/%7Epuppy/viewtopic.php?t=4956 I have been trying to set up DRI accelerated graphics for VIA Unichrome/Pro systems, specifically for the VIA Epia mini-ITX systems.
After several failed attempts, I obtained a unit for testing (thanks to mskuma) and now finally have it working. It was not necessary to use a modified kernel as I said then.
It was useful to refer to the files in your DRI-Kernelmodules.pup package, and what I found may interest you.

Your package certainly adds OpenGL (Mesa) 3D capability to my test VIA system, but the X server log does not report the all-important "direct rendering enabled".
And the 3D test utility, glxgears, yields only the same modest frame-rate (90 FPS) as I can obtain when there are no DRI modules loaded at all.
And yes, I installed the xorg_opengl-6.8.1 pupget, ran "install-DRI via", and added "Load "dri"" to xorg.conf before launching X. lsmod lists agpgart and via.

So it appears that DRI is not enabled with your VIA package. You might want to investigate this, yourself.
So I attach a package containing glxgears and glxinfo. I would be interested to learn what glxinfo reports with other graphics cards. It should report "direct rendering: Yes"

So what's the difference when DRI is enabled? With glxgears the VIA Epia achieves 430 FPS at 24bit and over 500 FPS at 16bit ... a dramatic improvement in anyone's language.
I will put together the VIA package shortly and make it available. This package could be easily adapted for other graphics cards, too. The DRI modules just need to be substituted.

Very good that you'll provide a package. I only can test SIS 650 and ATI 7000. SIS 650 has no 3D, ATI runs glxgears (Direct Rendering: yes) with 1900 fps. Without DRI just 300 fps.

I see that your DRI package is working well with the ATI card.

In the case of the VIA Epia CLE266, DRI cannot be enabled with Puppy's libGL library. I had to provide an updated version.
And neither will DRI work with Puppy's "standard" XOrg 6.8.1 VIA module (via_drv.o).

But the Epia graphics chips, referred to as "Unichrome", are somewhat different to other VIA chips.
My DRI / DRM modules and libGL libraries are from http://dri.freedesktop.org , an offshoot of XFree86/Xorg, and the main Xorg driver is from a separate project - www.openchrome.org
This project also provides the libviaXvMC libraries for the hardware MPEG2 acceleration feature of the Unichrome chips.

I recently read on the Openchrome mailing list that this driver is about to be incorporated into Xorg 7.0.

Here is a Dotpup with the VIA-openchrome 3D-files from tempestuous.

It includes updated GL-libs, the Kernel-Module, the X.org -Drivers, and an installer.

Install the dotpup, then choose "show-via-openchrome-info" in the Dotpups-menu.

show-via-openchrome-info is in the "Dotpups"-menu.
You also can click it in ROX in the folder /usr/local/via-openchrome

Or run "show-via-openchrome-info" in a consolewindow.

I it is my fault though as I have the boosted puppy and this
after all is a kernel module Smile

maybe MU or bombayrocker
would compile a set for that kernnel (please) Smile

I tried to install dris but everytime I try and run python on mine
it won't load lib files or do this "import os" thing I'm again not sure
why it does this yet

willhunt,
As long as Boosted Puppy still contains Xorg 6.8.1 then the only file that should need to be changed is the DRM kernel module, via.o.
This module should be compiled from source from http://dri.freedesktop.org/wiki/ against Boosted Puppy's lck-patched 2.4.29 kernel tree.
CVS download instructions are here - http://dri.freedesktop.org/wiki/Building under "Getting DRM". Then to build -

## cd into the correct directory for 2.4 kernels -
cd /drm/linux
make DRM_MODULES=via

rild,
I will try your suggestion of not using Option "EnableAGPDMA" "true" with mskuma's Epia ML8000A, and report soon.
