As mentioned in earlier commit, the riva and nvidia fbdev drivers have seen no love over the years, are short on features and overall below par
Users are encouraged to switch to the nouveau drm driver instead.

Hi all unless, there are objections I would prefer to merge this via the drm tree.
Have you tested that the resulting kernels work on the relevant hardware?
Sadly, no I haven't. I'm updating the defconfigs as requested by the fbdev maintainer.
The old drivers may be crufty but they presumably have been tested by people and at least somewhat work.
So I'd be inclined to leave the defconfigs alone until someone can test that the new driver works at all.
Works for me.
I gave it a quick spin on a G5 I have access to and dmesg has a bunch of errors in it (see below). I can't actually tell if the display is working because the machine is remote, and I can't go and check it at the moment because the office is closed.
From what I can see, there seems to be three bits:
- attempted out-of-bound attempts to read the vbios Genuine concern or noise? Likely using the bios from open firmware, check any of the other options - see NvBios in [1] - cannot figure out the timer input frequency No idea - the TV1 EDID is empty Is there an actual TV connected to the device, check with another cable
Regardless of the patches, reporting [2] the above would be a nice move.
