These lines were useful as basic device information,
and as reference to wiki "CodeNames"
http://nouveau.freedesktop.org/wiki/CodeNames

"This page contains a list of some NVIDIA chip code names and their corresponding official GeForce number. If you're running a recent version nouveau, you can find your chipset by doing dmesg | grep -i chipset. This will always be correct, whereas the lists below are approximate."

Notice "dmesg | grep -i chipset"

BTW "NVIDIA" is already visible via 'lspci' - lspci | grep VGA

So only gain is unnecessary information reduction and redundancy.

Please bring Chipset & Family back.

Hello poma,

The chipset didn't disappear and is still displayed: it is the G98 you get on the "[    2.483843] nouveau 0000:02:00.0: NVIDIA G98 (098200a2)" line. The "NV98" was the "Nouveau" chipset, but the switch was made to use the same naming as NVIDIA. So rather than displaying both the Nouveau version of the chipset and the NVIDIA one, it make sense to only use one, and to prefer the NVIDIA naming. (FYI, files name has been modified to follow the NVIDIA naming as well, along with envytools.)

As for the family, it can be easily deduced from the chipset in most cases: GMxxx are Maxwell cards, GKxxx are Kepler cards, GFxxx are Fermi cards, GTxxx are Tesla cards, and most reasonably, GPxxx will be Pascal cards. NV50, G8x, G9x, MCPxx are also Tesla cards. They do not follow the same pattern as newer cards and so it might not be as easy to identify their family. But there is the wiki page to help for that. 

Regards,
Pierre

If you decided to follow NVIDIA naming scheme, OK it is your concern as developers.
But it's not just the actual version and revision of the chipset, but also descriptive string itself - "Chipset".

(ALL!) all of the people around us they say
Can they be that close
Just let me state for the record
We're giving love in a family dose

We are family
I got all my sisters with me
We are family
Get up ev'rybody and sing

Nvidia is not just about video, but also audio,
so be more descriptive on device type and chipset as well.

NACK.

All the relevant information is shown, "nouveau" (video driver)
detected an "NVIDIA G98" (complete with full chip identification
register value for specifics).  I'm not bikeshedding this topic any
further than that.

Thanks,
Ben.
