[PATCH v3 1/2] drm: Introduce plane SIZE_HINTS property

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add a new immutable plane property by which a plane can advertise
a handful of recommended plane sizes. This would be mostly exposed
by cursor planes as a slightly more capable replacement for
the DRM_CAP_CURSOR_WIDTH/HEIGHT caps, which can only declare
a one size fits all limit for the whole device.

Currently eg. amdgpu/i915/nouveau just advertize the max cursor
size via the cursor size caps. But always using the max sized
cursor can waste a surprising amount of power, so a better
strategy is desirable.

Most other drivers don't specify any cursor size at all, in
which case the ioctl code just claims that 64x64 is a great
choice. Whether that is actually true is debatable.

A poll of various compositor developers informs us that
blindly probing with setcursor/atomic ioctl to determine
suitable cursor sizes is not acceptable, thus the
introduction of the new property to supplant the cursor
size caps. The compositor will now be free to select a
more optimal cursor size from the short list of options.

Note that the reported sizes (either via the property or the
caps) make no claims about things such as plane scaling. So
these things should only really be consulted for simple
"cursor like" use cases.

Userspace consumer in the form of mutter seems ready:
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3165

v2: Try to add some docs
v3: Specify that value 0 is reserved for future use (basic idea from Jonas)
    Drop the note about typical hardware (Pekka)
v4: Update the docs to indicate the list is "in order of preference"
    Add a a link to the mutter MR
v5: Limit to cursors only for now (Simon)

[PATCH v3 2/2] drm/i915: Add SIZE_HINTS property for cursors

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Advertize more suitable cursor sizes via the new SIZE_HINTS
plane property.

We can't really enumerate all supported cursor sizes on
the platforms where the cursor height can vary freely, so
for simplicity we'll just expose all square+POT sizes between
each platform's min and max cursor limits.

Depending on the platform this will give us one of three
results:
- 64x64,128x128,256x256,512x512
- 64x64,128x128,256x256
- 64x64

CI said the IGT was correctly skipping without the
kernel patches, and passed on all i915 supported
machines with the kernel patches in place. 

So looks like we're all good to merge this, as soon
as I get someone to review thew i915 patch...

PS. I forgot to cc dri-devel with this series, but bounced
    the whole thing there now.
