[Nouveau] Chipset & Family

[Pierre Moreau]

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
