search for: ch7006

I have a Dell Inspiron 8100 laptop (or I8K) with a NVidia Geforce2 Go (or NV11) with an embedded CH7007A chip, and am seeing the following after getting ch7006 kernel driver/module loaded: # dmesg |grep ch7006 -i --- Snip --- [ 21.191147] nouveau [ I2C][0000:01:00.0] detected TV encoder: ch7006 [ 21.404731] ch7006 1-0075: ch7006_probe: [ 21.411672] ch7006 1-0075: Detected version ID: 50 [ 21.421536] ch7006 1-0075: ch7006_encoder_init: [...

I believe that ch7006 is the only external encoder that's supposed to work, so you're in luck. It sounds like it passes the nv04_tv_identify stage of nv04_tv_create -- perhaps it fails later? Although based on the prints, it's even doing dpms stuff (but it hits _detect a second time... odd). Try booting with...

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! Looking at "drivers/gpu/drm/i2c/ch7006_mode.c", seems to be now setting the ch7006 "CH7006_POWER_LEVEL, FULL_POWER_OFF" on chips >=20, in which my chip ID is 50. This is upon the condition of, "...

...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: Add more...

Hello everyone, First of all - congratulations on the success of your project. It was about time the community did something about the nvidia drivers! :) Now, I'm still experimenting with nouveau and I have enabled it on a test system that has a rather old Nvidia card (GeForce4 I think) with tv-out. Everything works fine, but I haven't been able to find any examples on how to

I actually checked this out last night, grabbed the BT869 datasheet. Basically you'd have to implement something similar to the ch7006 driver (see drivers/gpu/drm/i2c), which provides an API for setting modes (the BT869 appears to have 8 of them, of which I'm guessing only 4 are actually usable, probably the RGB ones). Then you'd need to work out what the I2C index of it is, which you can tell by checking the VBIOS. Of cou...

...u just need some means to compute the optimal timings algorithmically given the connector properties and a rough description of the mode. Sure, using a fixed list of modes from which you pick the "closest" to the user's settings might be the easiest way to achieve that on some chips [ch7006 does precisely that IIRC], and that might be a slight underuse of the flexibility of some hardware, but the API doesn't force you to do that. > And then there's the Philips TV encoder chip, which has a similar freedom > in programming. > > Of course, given that analog TVs are d...

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).
