[9fans] Nvidia GeForce 6800 XT

[pavlovetsky]

This model is listed on the relevant wiki page as supported natively.
Now, I took a look at the nvidia.c and I found no explicit (commented)
references to it. I also did not find the hardware identification
numbers in the code. The identifications I was looking for I sourced
out of Nvidia web site here: http://www.nvidia.com/object/IO_18897.html
This page is the list of models along with their hardware numbers
(supported by the current linux driver). There are four numbers for
6800XT.

My question to the community: is there someone with actual experience
of using this card under Plan 9? And if there is, tell - how really
good the driver and does it really use this quite sophisticated
hardware?

The oldest wiki page where the native support is mentioned belongs to
Erik Quanstrom, so maybe he knows a bit more?

not really.  every time i've delt with nvidia cards,
(even on xf86 starting with the 440mx (?)) i've needed
to hack the driver with vid/did of my device.
iirc, the main thing you need to know is the approximate
generation of card.  you can generally google this.

i have to switch off hardware acceleration on the nvidia
G72M on my lenovo with plan 9, but i don't notice a problem
when using it.  (it does use hw cursor.)
of course, the 1,253 lines of code in aux/vga/nvidia.c
is just to get the device set up.
that's the trouble with sophisticated hardware.
if your particular one doesn't cause trouble with the hwaccel on,
9/pc/vganvidia.c will use fill and scroll, but that's about it.
(hw cursor can be selected separately.)

I have one in a Plan 9 terminal, driving a Dell 2407WFP at 1920x1200x16.
pci -v reports:

1.0.0:	vid  03.00.00 10de/00c3  11 0:dc000000 16777216 1:c000000c 268435456 2:00000000 16 3:dd000004 16777216 4:00000000 16
	NVIDIA

The label on the box says "GF 6800 XTreme 256MB DDR3 DUAL DVI TV PCI-E".
It seems fine, though I'm not watching movies on it.
