How to get up-to-speed on the 3D / DRI in Rage 128

How to get up-to-speed on the 3D / DRI in Rage 128

[Kevin B. Hendricks]

Hi,

I am about to start the Java 3D port to ppc and wanted to get some accelerated
3D capabilities for rage 128 going first.

I have noticed a few patches fly by recently on exactly this issue (also fixes
to panning, etc).

What is the best way to get up to speed quickly here?

I have the xf 401 src tar archives and I can get a hold of ani's cvs of the
xfree86 tree.

What other patches/fixes do I need to get going?

- aty128fb.c patches for panning?
- DRI patches?
- etc

Any quick pointers would be greatly appreciated.

BTW: We really do need a developers searchable patch archive for major systems
like XFree 4.0, the kernel, drivers, gcc, binutils, glibc, etc

Thanks

Kevin

I haven't used Ani's patches, and I seem to be the only one running DRI
successfully so far. Maybe better try without them first.

Not needed, you can use the full screen.

Yep. What I'm running is the DRI CVS trunk (which is basically X 4.0.1 and
some DRI changes) and a patch that I've posted to dri-devel. If you can't get
it from there, I can send it to you privately or put it up for HTTP download.

(Jack Howarth should have it as well)

That's all I can think of ATM.


Good luck Kevin,

Michel

Yes, I found patches named drm-r128.diff and drm_panning.patch you posted
recently to the dev list.

Where or how do I go about getting the DRI CVS trunk?  Is this a project on
sourceforge?  Is there anonymous cvs access?

Great.

Thanks Michel

The second one is just for aty128fb's panning and not directly related to DRI.

The first one is to get the DRM kernel module working, but you can also build
that from the DRI tree - read below ...

The great news is that I've just been added to the DRI project at sourceforge
(http://dri.sourceforge.net). I'll start a PPC branch which you should be able
to just checkout and build and it should work (and which will eventually be
integrated into the trunk of course :).

I'll post the announcement for that branch to this list as well.

For the user aspects of DRI, check the DRI user guide at sourceforge and/or
the dri-user mailing list there.

No, the needed libGL is included.

Unfortunately, it takes some time for my write access to the repository to
take effect (until some cron job at sourceforge adds me to group dri ;) .

I've put a diff of the modifications I made up here for the impatient:

http://n.ethz.ch/student/daenzerm/download/XFree86/dri.diff.bz2


Checking out the DRI CVS trunk and applying this patch should enable you to do
'make World; make install' and use DRI. YMMV :)

Please let me understand... I d/l the latest X + DRI patches and I compile
them. If all goes right I get a working X, but how can I use the 3D
acceleration ?  Do I need a patched version of Mesa too, or what ?

Bye.
