That's right. However nouveau/master (http://cgit.freedesktop.org/nouveau/linux-2.6/) has some very preliminary support, you'll need to extract graph firmware from the blob (see http://nouveau.freedesktop.org/wiki/NVC0_Firmware/) as well as xf86-video-nouveau 1.0.10.

Ok, kernel driver not support GK208 at all.

Any ideas?

You used the nouveau/master kernel, right? What's in dmesg? Does it say that it can't find the VBIOS perchance? If so, you may need to try the drm-next tree -- it has a fix that's not in nouveau/master (but should have almost all the commits in nouveau/master by now).

Also note that the card is marked as a 3d controller. That means it probably has no outputs (but not necessarily) and that it can really only be useful for 3d accel. That part is not in nouveau/master, if you want you can look at http://cgit.freedesktop.org/~darktama/nouveau/ for some _very_ prelim support -- this allows you to build an "out of tree" kernel module. You'll still need to extract graph firmware from the blob mmiotraces, but I wouldn't really expect 3d accel to actually work properly quite yet.

I'm not sure what you're trying to achieve by filing this bug. The GK208 is essentially unsupported hardware ATM -- there's some very prelim support atm, and it's being worked on. If you'd like to contribute, it's probably best to join #nouveau on irc.freenode.net.

> I'm not sure what you're trying to achieve by filing this bug. The GK208 is
Try to find any working combination of drivers. nvidia blob on this hardware periodically stops screen output, notebook not survived suspend-resume. 

If you need other traces, testing patches - let me know.

If you grab envytools from git, demmio should be fixed.

However I'll reiterate -- your gpu has no outputs, so it's only good for 3d acceleration. With the nouveau driver compiled from http://cgit.freedesktop.org/~darktama/nouveau/log/?h=devel-pm (and the graph firmware extracted as per the earlier instructions) you might have a functioning graph unit [I'm not even sure of that], but the current mesa has no knowledge of the GK208 (NV108), and is quite unlikely to work. I think that GK208 is similar to GK110 in terms of ISA, which has dodgy-at-best support presently in mesa, so I wouldn't expect any quick miracles.

If you're interested in working on this yourself, join us in #nouveau, otherwise wait a few months before trying again. I'm closing this, since there's no point in having it open -- the GK208 just isn't supported atm, esp wrt 3d accel.
