We're adding a new enum COLOR PIPELINE property. This
property will have entries for each COLOR PIPELINE by
referencing the DRM object ID of the first drm_colorop
of the pipeline. 0 disables the entire COLOR PIPELINE.
Userspace can use this to discover the available color
pipelines, as well as set
Certain operations require us to preserve values below 0.0 and
above 1.0 (0x0 and 0x respectively in 16 bpc unorm). One
such operation is a BT709 encoding operation followed by its
decoding operation, or the reverse.
We'll use s32 values as intermediate in and outputs of our
color operations,
The if/switch statement is bound to grow with more types and
subtypes. Pull this out into its own funcion to make things more
manageable and readable.

Unit testing this in VKMS shows that passing 0 into
this function returns -1, which is highly counter-
intuitive. Fix it by checking whether the input is
>= 0 instead of > 0.

fixp2int always rounds down, fixp2int_ceil rounds up. We need

We'll construct color pipelines out of drm_colorop by
chaining them via the NEXT pointer. NEXT will point to
the next drm_colorop in the pipeline, or by 0 if we're
at the end of the pipeline.

- Allow setting of NEXT property to NULL (Chaitanya Kumar Borah)

- Add next pointer to colorop

Add a read-only TYPE property. The TYPE specifies the colorop
type, such as enumerated curve, 1D LUT, CTM, 3D LUT, PWL LUT,
etc.
v4:
- Use enum property for TYPE (Pekka)
v3:
- Make TYPE a range property
- Move enum drm_colorop_type to uapi header

We want to be able to bypass each colorop at all times.

When the floor LUT index (drm_fixp2int(lut_index) is the last

A value of 0x8000 and higher should round up, and

This is an RFC set for a color pipeline API, along with a sample
