9e070c0840 backend-drm: obtain DRM backend from listener in session_notify()
The session_listener is embedded in the DRM backend structure.
Use this to obtain the DRM backend with container_of().

That way the DRM backend will not have to be found from the compositor.
This is trivial now, but in the multi-backend case would entail
iterating over all backends to find the correct one.

bcacd9ec5a backend-drm: schedule connector disable for detached head
Currently, if a head is detached, the entire state of the device is invalidated
to make sure that the connector is disabled on the next atomic commit. Side
effect of the invalid state is that all planes are disabled on the next commit.
This includes planes that are used with a different head that is not part of the
next atomic commit. Disabling the planes of unrelated outputs causes a blanking
of these outputs until output is repainted and the plane is reenabled.

Store the detached heads in a list on the output and disable the connectors for
all heads in this list in the next atomic commit.

f95c2986dd drm: allow to skip composition if pending capture is writeback
We have an optimization to skip composition if there's no damage on the
primary plane and we already have a renderer buffer active. But we don't
allow this optimization if there's a pending capture task for the
output. For the renderer-based sources, that is really necessary, but
for the writeback source we should allow this optimization.

94afcbcdc3 backend-drm: Select plane based on current attached CRTC
When doing plane selection for an output CRTC check if the plane
already has a CRTC attached and if so prefer that plane only for
the corresponding CRTC.

This prevents changing a CRTC's primary plane when it is active
which is not allowed by the DRM framework.

c9b7c7085a backend-drm: add scanout tranche even for views eligible for direct scanout
We log the reasons why the fb of a certain view was not placed in an
overlay plane and use that for debug purposes. With these reasons we
also decide if the scanout tranche should be included on the dma-buf
feedback or not. For instance:

  1. If the reason is the incompatibility between the format/modifier
     pair of the fb and those supported by the KMS device, the scanout
     tranche is added and feedback is re-sent (so that the client can
     re-allocate with parameters that makes it eligible for direct
     scanout).

  2. If the reason is because we have no overlay planes available, the
     scanout tranche is useless. So the scanout tranche is removed and
     the feedback re-sent (so that clients can re-allocate with
     parameters optimal for the render device).

Also, when we detect that a view is eligible for direct scanout, we
don't even consider sending new feedback, as our interpretation of the
dma-buf feedback spec was that we should avoid bothering clients with
new feedback when they are already hitting direct scanout.

After some discussions and clarifications regarding the spec, we've
realized that Weston should start to also include the scanout tranche
even when the compositor is able to place client's content on overlay
planes. Basically, because this gives a chance for clients to
re-allocate with the proper parameters (not only format/modifier pair,
but also the target_device and the flags) from the scanout tranche. In
this patch we start doing this.

d5e5428478 backend-drm: don't copy the fence fd when duplicating the plane state
The state does not own the fd. This is usually not a problem, because the
in_fence_fd of the state is assigned during drm_assign_planes() and then
immediately used in drm_repaint_flush(). It cannot be closed in-between.

However, in the fallback path in drm_output_start_repaint_loop(), the state is
duplicated. At this point in time, the in_fence_fd may be invalid because it was
replaced in a new commit of the corresponding surface.

The plane state was already committed to the kernel when it is copied, so the
fence is no longer needed. So just clear it.

0edcc9e5ba backend-drm: don't try to commit an empty state
With multiple DRM devices, the state for one device may be empty during
repaint_flush(). This can happen for example if an output of one device triggers
the repaint and there are no screens attached to the other device and therefore
no active outputs.

The atomic commit will actually fail because the commit contains the
DRM_MODE_PAGE_FLIP_EVENT flag but no CRTCs.

Avoid this by skipping the commit entirly. There is nothing to to anyways.

device before reusing a drm_fb.

27ce9dadd8 backend-drm: Do not overwrite plane's index when creating virtual plane
Starting with commit 4cde507be6 "backend-drm: fix plane sorting" the
plane list will have a descending order of the planes rather than ascending.

This reversed order had the side-effect of exposing the fact that we
don't set-up a plane index when creating the drm_plane using the DRM
virtual API. Without settting a plane index for that drm_plane we
effectively overwrite the plane index which has the 0 (zero) entry.

This wasn't an issue before commit 4cde507be6 "backend-drm: fix
plane sorting" as it seems we never picked up that plane index as
being a suitable one due to the fact that those were assigned to primary
planes, but after that commit, the cursor plane will be one getting
the 0 (zero) plane index.

Finally, this would trip over because we attempt to place a (cursor)
view on a primary plane (where it would've normally be a cursor
plane) and we end up with no framebuffer ref.

This is fixed trivially by assigning a plane index, different than the
ones already created by create_spirtes().
