NV130 - gtx 1050 ti

NV130 - gtx 1050 ti

[Karl Schmidt]

This is sort of working -- but

I can't get it to do a 4k output.

Not sure how the monitor resolution is detected -
This monitor is supposed to do 3480x1200 60hz 4:4:4

But the info I get from hwinfo is different.

How does nouveau get this information?

If it is from an ID - with a list - the list is probably is wrong.

First things first -- I've alluded to this before, but let me be clear
-- there is no global database that contains monitor-specific
information which is used by any linux drivers. Please forget any
notions you had of such a thing existing or being used.

The information comes from the EDID blob supplied by the monitor.
Presumably hwinfo has a primitive EDID parser, which is where that
information comes from. A more complete EDID parser is available at

https://cgit.freedesktop.org/xorg/app/edid-decode/

For example,

$ ./src/edid-decode/edid-decode /sys/class/drm/card0-DVI-D-1/edid

Prints the full EDID information for the monitor connected on that
connector. Note that some monitors require special settings in order
to expose the higher resolution modes, and others only make them
available on some inputs but not others. No idea if yours is that way
or not.

It's quite likely that nouveau doesn't support using YUV outputs
though (which I'm guessing is what the 4:4:4 thing is referring to...
I always get confused by such notation), only RGB. Also there's no
HDMI 2.0 support in nouveau as yet, mostly due to lack of interest and
hardware. However you should still see a 4k@30 mode exposed
(probably).

Cheers,

Thanks for you useful reply. That did the trick - I got quite different information than I did with 
hwinfo or get-edid but more important - different than what I see in the Xorg.0.log.  ( I think 
deid-decode is the most complete).

So I'm guessing that nouveau computes the modelines from the combination of what the card and edid 
claim they support.

Sadly, it is a throw back to 'Chroma subsampling' (my days designing with NTSC editing hardware 
still haunt me.)  They reduce the color information so there is less bandwidth in the cable. (thus 
displayport and thunderbolt3 are headed to 40G (need 18G+overhead or 20G for 12bit 3840x2160 60hz 
RGB or only 12G+ for 8bit(24))

HDMI2 does support RGB - see:
http://www.hdmi.org/manufacturer/hdmi_2_0/hdmi_2_0_faq.aspx#146

The main wiki page probably ought to say what subsets of HDMI nouveau supports.  Some of the chip 
sets from back in the 900 series support hdmi2.0 - so to say nouveau supports that chip sort of 
implies that it does hdmi2.0.  Anyway - 4k monitors/TVs are getting cheaper and really helpful for 
someone coding - soon will be common.  I've got another card coming that I can test with.

With some limitations, it will take the list of modelines in the EDID
(which, mind you, might be just VIC id's), and compare it to what it
believes the hw capabilities are, and pass through only that list of
modelines that it thinks the hw will generate. This is what you should
see in the xrandr --verbose list. For HDMI, we currently have a hack
to allow up to 297MHz pixel clocks for Kepler+ GPUs. However for HDMI
2.0, I think there's some more stuff. And it's not clear that we're
parsing the capabilities correctly on such GPUs.

If you have concrete suggestions for improving any specific page, I'd
be happy to make the edits for you. Unfortunately many parts of the
wiki are "too far gone" so to speak, in terms of
inaccuracy/incompleteness.

Thanks - I suspected it was too new.

I'm finding the monitor capabilities miss identified even if I use an older
card - I'm guessing that nouveau talks to the monitor to get the an ID?
And then passes that to some part of xorg or something that looks up the id
number?

There have been several hardware detection bits over the years - I did a
dependency tree on xorg and still don't know where to find it.

Who should I contact to get them the correct monitor info?



The monitors store this info themselves in an i2c-accessible blob. Nouveau
will just read that out and pass it on, like all other drivers do. The EDID
contains info about modeline, etc.

Hello,

Acceleration for Pascal cards is coming in Linux 4.12, support for Pascal cards
in xorg-video-nouveau is in 1.0.15, and if I remember correctly, on the
Mesa-side, you will need >=17.0.
