Hello DRI developers,
on my ThinkPad T20, I experience Lockups with either type of DMA, be it
Vertex DMA or AGP texture access. With <Option "DmaMode" "None"> and
<Option "AGPMode" "2"> glxgears runs perfectly, as does glxinfo, whereas
ppracer locks up the system at start (supposedly because of using AGP
texturing). If I add <Option "BusType" "PCI">, everything works as
expected.
Did you suspend/resume the notebook? There was a problem with AGP after
resume that can be worked around by using BusType PCI. I suspected that
the bug was actually in the VIA AGP driver, not in the Savage driver. I
never got around to looking into it in detail though.

Hello developers,
The red/blue stereo rendering of xmakemol doesn't work with savage
hardware acceleration, but looks fine without (LIBGL_ALWAYS_INDIRECT=1).
This is true for the current DRI snapshot as well as for an older
snapshot from about August of last year. Do you need further information
for debugging this problem?
Screenshots are on http://www.physik.fu-berlin.de/~karcher/good.png
(software rendered) and http://www.physik.fu-berlin.de/~karcher/bad.png
(hardware rendered).
No one has been working on the Savage 3D driver in a while. Your odds of
getting someone to look into this problem are fairly low ATM. Sorry.
Feel free to open a bug in the freedesktop.org bugzilla.
Correcting myself. There have been updates to the Savage driver after I
stopped working on it by Ian Romanick, Brian Paul and Eric Anholt and
maybe others. Sorry folks, I appreciate your work! Is anyone going to
look into this xmakemol issue?
I took a quick look at xmakemol. The first thing I'd check is if the
driver code for glColorMask is operating properly. For red/blue
stereo, the scene is rendered twice, first with glColorMask(T,F,F,T),
then glColorMask(F,F,T,T).
I don't have a Savage card to test anything myself. Looks like the
driver's ColorMask code depends on the card model. Which card are you
using?
BTW, the author of xmakemol needs to be taught how to use function
prototypes. Put them in a header file; don't repeat the prototype
inside each and every function it's used in!
