About all I could do was reproduce the problem; I don't have radeon docs
yet to try and figure things out. I've been off getting GTK+ 2.2, Mozilla
and Qt3 font stuff straightened out.
The existence of three separate development teams working on the radeon
drivers is a bit of a problem, but I'm really unsure how to fix things.
Probably the worst off right now is the XFree86 tree which has neither
working video nor 3D on many radeon chips, and which routinely hangs when
switching VTs.
I currently run the tcl-0-0 branch on my desktop 7500 and XFree86 on my
laptop M6 -- and that with DRI disabled so I can switch VTs. The tcl-0-0
branch doesn't display video correctly, but does 3D while the XFree86 tree
doesn't do 3D, but does video on a select number of chips, the M6 is one as
I hacked the driver to at least get that working.
I submit that we need some sort of plan on how to get this mess resolved;
I'd like to get to a state where 3D and video runs on most chips, and at
least doesn't hang on the others. What I'd like to see is:
+ The kernel driver for the tcl-0-0 branch
This gives us the best chance at API compatibility into the future
as people are able to migrate to a tcl GL library, and should
reduce the kernel driver churn a bit.
+ The video patches from XFree86
These display reasonable video on the 7500 and others. They
don't currently work on the 8500, but I'll go get one of those
and make them work when I've got a spare minute or two. I don't
think the problems are all that hard. I'll see about stealing some
bits from GATOS, but that code doesn't generally cover the hardware
as completely as the XFree86 driver needs to.
+ The regular DRI GL bits
These have some important fixes missing from the XFree86 tree while
not incorporating all of the tcl changes which are probably less
well tested on older Radeon cards.
