Hello, I have here a GeForce 2MX (NV10) with a Brooktree BT869 chip for the TV-Out. Is the TV-Out on this card supported by Nouveau? I read on the feature matrix something that the TV-Out is only supported for some Chrontel chips, furthermore xrandr -q shows me only the DVI connection (in fact it's VGA, not DVI), but not the S-Video connection. If not supported, is this planned for future versions? I'm using the Nouveau X-server 1.0.1 and kernel 3.2.0 on Debian Wheezy. Thanks in advance for your help, Nil...

...nly has a few modes built-in. The BT is actually a very flexible chip, and supports a very wide range of modes with different overscan amount, plus different filtering options. It probably wouldn't be hard to just take a few modes from nvtv and put them into nouveau, similar to the (very few) Chrontel modes. What's missing is some sort of infrastructure in X to say "look, on this hardware there are these two functional blocks (CRTC + BT), I would like to program with the following values, and I've specified the values in the config file, or I'm a user space program and provide...

We don't actually set the exact mode passed by the user. Instead, the mode (both the CRTC mode and the final output mode) can be adjusted to the "closest" supported mode compatib...

...some new standard TV properties. OTOH, I think merging drm-next would do no harm. PATCH1-2 haven't been pushed there yet, I will forward them to dri-devel@ shortly. So, this should make TV-out work on all the pre-nv50 GPUs with an integrated encoder (that is, nv17-nv4x, nv2x excluded). Only Chrontel ch7006 and similar external encoders will work for now, implementing more should be straightforward as they seem to be all documented. Another patchset follows with some DDX modifications needed to make use of this. [PATCH 01/12] drm: Fix drm_cvt_mode() for interlaced modes. [PATCH 02/12] drm: Ad...

It seems it was only locking up in the context of nouveau_hw_save_vga_fonts, when it actually did something (because the console wasn't already in graphics mode).

After analyzing verbose nouveau & drm dmesg, I have found seemingly no more useful details pertaining to having no TV-1 device. The TV-1 device might be getting lost within DRM, by setting the TV-1 (SVIDEO, Composite) device into DPMS mode or Full Power Down mode, and the ch7006 datasheet does say in this mode, all but the i2c circuits are disabled!
