Hi,
This is my work in documenting EVO.
I did some RE to fill missing gaps.

...blob/master/drm/nouveau/nv50_display.c#L1808
and surrounding items. Looks like lut_clr sets 0x40000000 which was
previously not used. Not sure what the difference between that and
0x00000000 is. This is what we have in rnndb for it:
https://github.com/envytools/envytools/blob/master/rnndb/display/nv_evo.xml#L408
So bit 30 is mode, set is "high res", unset is "low res". So really
what we want is 0x80000000 which leaves the LUT enabled but uses the
low-res mode?
All this could use some playing-around with.

...s well) should support
higher bpc over HDMI. However there's no support for that in nouveau
right now. I happen to have a monitor (TV) that advertises 12bpc
support, so I may play with it.
Here's how dithering is controlled:

(and also exposed in the public display class docs at
http://download.nvidia.com/open-gpu-doc/Display-Class-Methods/2/ )
In theory turning off dithering should also flip off that ENABLE bit,
but perhaps we messed something up. Or HDMI is extra-special and
doesn't respect that bit and...

That's already the case -- NVIDIA actually has like 5 different LUT
modes on recent chips.
