a0f8276fe8 ("compositor-drm: Disallow overlapping overlay planes") was
a little too pessimistic in rejecting occluded views. Whilst it
correctly prevented overlay planes from occluding each other, it also
prevented overlay planes from occluding the scanout plane.
This is undesirable: the primary/scanout plane is specified to stack
strictly below all overlay planes, so there is no need to reject a plane
from consideration for scanout due to being occluded by an overlay
plane.
Shift the check downwards so it only applies to overlay rather than
scanout planes.

In the plane-only mode, we try to place every view on a hardware plane,
and fail if we can't do this. This requires a full walk of the scene
graph to come up with a complete configuration in order to be able to
test.
In mixed mode, we know at least some visible views will fail to be
promoted to planes and must be composited via the renderer. In order to
still use some planes where possible, we use atomic modesetting's
test-only mode to incrementally test configurations.
We know that the renderer output will always be visible, and because it
is the renderer, that it will be occupying the scanout plane underneath
everything else. The actual renderer buffer doesn't materialise until
after assign_planes, because it cannot know what to render until then.
However, in order to test whether a configuration is valid, we need the
renderer buffer in the scanout plane. For testing, we fake this by
temporarily stealing the old buffer - if it seems sufficiently
compatible - and placing it in the state we construct. This is used to
test whether or not a renderer buffer will work with the addition of
overlay planes.
Doing this incremental testing will allow us to enable plane usage for
atomic by default, since we know ahead of time that our chosen plane
configuration will work.

Add a new mode, which attempts to construct a scene exclusively using
planes. This is a building block for incrementally testing and
constructing state: in the plane-only mode, we test the state exactly
once, when we have constructed a full set of planes and want to know if
it works or not.
When using the renderer, we need to incrementally test views one by one
to see if they will work on planes, falling back to the renderer if not.
This test is different, since the scanout plane will be occupied by the
renderer's buffer. Testing using the renderer or client buffers may have
completely different characteristics, so we need two passes: first,
constructing a state with only planes and testing if that succeeds,
falling back later to a mixed renderer/plane mode which tests
incrementally.
This implements the first mode, and preferentially attempts to use it.

Add support for multiple modes to drm_output_propose_state. Currently we
intend to operate in three modes: planes-only (no renderer buffer,
client buffers in planes only), mixed-mode (promote client buffers to
planes where possible, falling back to the renderer where not), and
renderer-only (no plane usage at all).
We want to use the first (planes-only) mode where possible: it can avoid
us having to allocate buffers for the renderer, and it also gives us the
best chance of the optimal configuration, with no composition. In this
mode, we walk the scene looking at all views, trying to put them in
planes, and failing as soon as we find a view we cannot place in a
plane.
In the second mode, rather than failing, we assign those views which
cannot be on a plane to the renderer, and allow the renderer to
composite them.
In the third mode, planes are not usable, so everything but the cursor
goes to the renderer. We will use this when we cannot use the planes-only
mode (because some views cannot be placed in planes), but also cannot
use the 'mixed' mode because we have no renderer buffer yet. Since we
walk the scene graph from top to bottom, using atomic modesetting we
will determine if planes can be promoted in mixed mode by placing a
renderer buffer at the bottom of the scene, placing a cursor buffer if
applicable, then testing if we can add overlay planes to this mode.
Without a buffer from the renderer, we cannot do these tests, so we push
everything through the renderer and then switch to mixed mode on the
next repaint.
This patch implements the mixed and renderer-only modes (previously
differentiated only by the sprites_are_broken flag), with the
planes-only mode being left for a later patch.

this as failed and go back to repaint through composition.

Now that we collect information about which modifiers are supported for

Client buffers from dmabuf already store multi-plane and modifier
information into drm_fb. Extend this to drm_fb_get_from_bo(), used for
wl_buffer, cursor, and gbm_surface buffers. wl_buffer buffers should by
convention not require modifiers. Cursor buffers must not require
modifiers, as they should be linear. Prior to this patch, GBM buffers
must have been single-planar, and able to used without explicitly naming
modifiers.
Using gbm_surface_create_with_modifiers allows us to pass the list of
modifiers acceptable to KMS for scanout to GBM, so it can allocate
multi-planar buffers or those which are otherwise only addressible with
modifiers. On platforms supporting and preferring modifiers for scanout,

timing of a video mode, which is considered as a standard for
HDMI certification and compliance testing. It defines each and every
parameter, of a video mode, like h/vactive,h/vfront h/vback etc.,
including aspect-ratio information. The drm layer, specifies the
aspect-ratio information in user-mode flag bits 19-22. For the non-CEA
modes a value of 0 is given in the aspect-ratio flag bits. Each
CEA-mode is identified by a unique, Video Identification Code (VIC).
For example, VIC=4 is 1280x720@60 aspect-ratio 16:9.
This mode will be different than a non-CEA mode 1280x720@60 0:0.
The new mode-format helps to differentiate between the CEA and
non-CEA modes, by letting user specify aspect-ratio along with other
paremeters: mode=widthxheight@rr ratio.
This helps when certification testing is done, in tests like 7-27,
the HDMI analyzer applies a particular CEA mode, and expects the
applied mode to be with exactly same timings, including the
aspect-ratio and VIC field.

Add a new boolean output section key "force-on". When set to true, the
output will be enabled regardless of connector status. This is the
opposite of the mode=off setting.
Forcing connectors on is useful in special circumstances: avoid output
configuration changes due to hotplug e.g. with KVM switches, or hardware
with unreliable connector status readout for example.

Add a new output section key "same-as" for configuring clone mode. An
output marked "same-as" another output will be configured identically to
the other output.
The current implementation supports only CRTC sharing for clone mode.
Independent CRTC clone mode cannot be supported until output layout
logic is moved from libweston into the frontend and libweston's damage
tracking issues stemming from overlapping outputs are solved.
Quite a lot of infrastructure is needed to properly configure clone
mode. The implemented logic allows easy addition of independent CRTC
clone mode once libweston supports it. The idea is that wet_layoutput is
the item to be laid out and all weston_outputs a wet_layoutput
contains show exactly the same area of the desktop.
The configuration logic attempts to automatically fall back to creating
more weston_outputs when all heads do not work under the same
weston_output. For now, the fallback path ends with an error message.
Enabling a weston_output is bit complicated, because one needs to first
collect all relevant heads, try to attach them all to the weston_output,
and then back up head by head until enabling the weston_output succeeds.
A new weston_output is created for the left-over heads and the process
is repeated.
CRTC-sharing clone mode is the most efficient clone mode, offering
synchronized scanout timings, but it is not always supported by
hardware.
v10:
- rebased trivial conflicts in man page
- switch to gitlab issue URL
v9:
- replace weston_compositor_set_heads_changed_cb() with
weston_compositor_add_heads_changed_listener()
- remove workaround in simple_head_enable()
v6:
- Add man-page note about cms-colord.
- Don't create an output just to turn it off.

Rename the IVI tests to be more consistent with the others, and invert
the naming of plugin/client to make it slightly more clear what's going
to happen. Handle the renaming by using wet_get_binary_path to rewrite
the local binaries.
As a side-effect, weston.ini ivi-shell-user-interface no longer needs to
be given as an absolute path.

v2:
Call ivi-layout.ivi as ivi-layout-test-client.ivi to keep the same name
in both the file and the lookup, so that the module map does not need to
change the name.
Update code comments to reflect the new names.
Rename ivi_layout-test-plugin.c to ivi-layout-test-plugin.c.
