Unfortunately the ABI is a little annoying around almost requiring a 256-entry lut. While that is being worked out, allow proper mapping of colors in 30bpp framebuffers.

https://bugs.freedesktop.org/show_bug.cgi?id=54646 Bug #: 54646 Summary: i2c failure on Quadro NVS 4200M (GF119 (NVD9)) Classification: Unclassified Product: xorg Version: unspecified Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Driver/nouveau

This is what was done prior to the big refactor in kernel 3.8, and what was done by xf86-video-nv. Experimentally, it seems like there's some sort of issue with the high-res lut to be used there. Tested on G92. This ends up mattering because fbcon/fbdev chooses the C8 fb format for low-vram systems, which can occur with some IGP-based configurations with little "stolen" vram.

Commit df8dc97cd17 (drm/nouveau/kms/nv50: use drm core i2c-over-aux algorithm) switched things over to the drm algo. Unfortunately it generates address-only transactions. Prior to GF119, the hardware had no support for such things, and GF119+ the nouveau code did not handle these properly. The result of this bug is that EDID doesn't make it over for DP (and eDP) screens, which in turn wreaks

Other gpu drivers have some driver-specific documentation, so it would nice if nouveau did as well. This adds a bare-bones ReStructured Text document with sections for module parameter documentation, an overview of the driver architecture, a section for internal API documentation, and a glossary for nouveau-specific terms. To make the document a little less bare, I've included docblocks for

The hardware supports either size. Also add checks to ensure that only these two sizes may be used for supplying a LUT. Finally, experimental evidence suggests you can't mix sizes for degamma and gamma. Disallow this as well.

Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- Only tested on G84 and GK208. The GV100+ is entirely untested. With the fixed modetest tool, setting ilut and olut sizes to different quantities seems to work out OK, across a range of formats (XR24, XB30, XB4H).
