Some platforms (e.g., Intel SKL+) support a programmable background canvas
color below the hardware planes. For more details, see the cover letter for
the previous version of the series posted here:
https://lists.freedesktop.org/archives/intel-gfx/2015-October/078687.html
I haven't made any updates to libdrm or IGT since the last update, so I'm only
reposting updates of the kernel patches; use the link above to get to the
corresponding libdrm/igt changes.
Note that this series isn't mergeable yet since we don't (yet) have an open
source userspace that can make use of it. Eventual userspace candidates for
this functionality might be Weston, ChromeOS, or Android hwcomposer.

To support CRTC background color, we need a way of communicating RGB
color values to the DRM. However there is often a mismatch between how
userspace wants to represent the color value vs how it must be
programmed into the hardware; this mismatch can easily lead to
non-obvious bugs. Let's create a kernel-side property type that
standardizes the user<->kernel format and add some macros that allow
drivers to extract the bits they care about without having to worry
about the internal representation. This RGBA property type may also be
useful for future properties like color keys.
These properties are still exposed to userspace as range properties, so
the only userspace change we need are some helpers to build RGBA values
appropriately.
v2:
- Just use 'struct rgba' rather than a typedef as our opaque RGBA
datatype. (Emil)
- Actually use drm_property_create_rgba() to create the background
color property. (Bob)
- Add helper to build 64-bit RGBA internal value in appropriate format
(e.g., for the initial value when attaching a property). (Bob)

Gen9 platforms allow CRTC's to be programmed with a background/canvas
color below the programmable planes. Let's expose this as a property to
allow userspace to program a desired value.
This patch is based on earlier work by Chandra Konduru; unfortunately
the driver has evolved so much since his patches were written (in the
pre-atomic era) that the functionality had to be pretty much completely
rewritten for the new i915 atomic internals.
v2:
- Set initial background color (black) via proper helper function (Bob)
- Fix debugfs output
- General rebasing

I'm not a fan of the drm_rgba thing having alpha in the low bits. It
goes against the existing precedent set by eg. the colorkey ioctls
where alpha (if it would be used) would be in the high bits. I think I
complained about this before already, or maybe it was also about
some BGR vs. RGB ordering thing?
Looks like drm_rgba isn't actually part of this series, and I can't see
it in the tree either, so I guess it comes in via some other series?

drm_rgba was in patch #1 of this series; if that didn't come through for
you, it's in patchwork here:
https://patchwork.freedesktop.org/patch/73224/
We could certainly flip around the internal ordering of bits, but I'm
not sure it really matters. The whole point of drm_rgba is to be
somewhat opaque so that drivers don't try to work directly on the
internal representation (and potentially misinterpret the format).

Sure. Just goes against existing practice a bit. And feels a bit
strange to have the component that's most often the one that's not
present occupy the low bits.
OTOH the fact that RGBA is a fairly obscure format hardware wise,
might catch people trying using the API the wrong way.
