improvement with i915 driver from before
(suspend and resume with i830 DRI would suspend fine, but resume would
lead to a hung machine after X restarted).

Use
pci_alloc_consistent in the init function surviving over a suspend. The
impression I got from asking people was that a DMA mapping such as that
would -not- survive a suspend cycle.
Info / feedback welcome :)

Did you talk at all about memory mngmt? For instance when setting a mode
is it needed
mode. The 'radeon' part, of course, would
make sure that the wrong code wasn't used. Likewise, the userspace
program could be fed any data it needed this way.
Anyhow, just an idea. No idea if it's a good one or not, really; but I'd
love to hear feedback.

Welcome
the major rendering glitch with the mach64 on the walls - the

Also, there's no mipmapping, but that's less of an issue.

Is the mach64 code based on X 4.2.0? Is it based on X CVS?
I'd like to know so I can build it properly here, and not bork up.

As far as I know, every new graphics chip out there right now is programmable - it may
have a limited number of operands but the microcode is certainly modifiable. They
aren't just straight ASICs.

This doesn't support your conclusions here. I would hazard a guess that memory
performance there had more to do with the chipset involved than superior memory
technology.

I'm using an older version of the mach64 code, but I also get this. Perhaps there's an
issue with the Z buffer or such? I don't know a lot but that sounds probable if it's
not being consistently drawn.

Perhaps a good idea here would be to have some sort of a function
documentation tracking project.. I have been doing a hell of a lot of
PHP
See above text why function documentation is not necessarily the best
if it's relevant (or even safe, registers could
change and not be restored), but so far as I can see it could really help
with devel time.
