We map view alpha(0.0-1.0) to plane state's alpha
by using the max plane alpha value got from drm.

This checks whether plane alpha is supported.
We get range of alpha value supported for plane
which is required for mapping view's alpha(0.0-1.0)
with drm plane alpha. No functional change.

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.

We can save a bit of work by using the output_to_buffer_matrix we've

Add a mode argument to weston_buffer_reference which indicates whether a
buffer's storage may/will be accessed, or whether the underlying storage
will no longer be accessed, e.g. because it has been copied. This will
be used to retain a pointer to the weston_buffer whilst being able to
send a release event to the client.

Currently each drm_fb takes a reference on a client buffer it wraps.
This prevents us from being able to reuse a drm_fb in multiple places
(e.g. two views of the same client buffer) simultaneously, or even back
to back.
Move the buffer reference to the plane state, as preparation for
allowing drm_fb to be cached inside the weston_buffer.

This header is for sharing fallback definitions for drm_fourcc.h. A new
test in tests/yuv-buffer-test.c is going to be needing XYUV8888 format,
and more new formats will be expected with HDR supports.
Share these fallback definitions in one place instead of copying them
all over.
All users of drm_fourcc.h are converted to include weston-drm-fourcc.h
instead for consistency: have the same definitions available everywhere.

This moves the creation of the blob to be earlier, to when the damage is
calculated. It replaces the damage tracked inside of the plane state
with the blob id itself.
This should stop creating new blob ids for TEST_ONLY commits, and them
being leaked in general, as the blob ids are now freed with the plane
state.
The FB_DAMAGE_CLIPS property is now always set if it's supported, and
will be 0 in the case that we have no damage information, which
signifies full damage to the kernel.

In order to better optimize view assignment to HW planes, we construct
an intermediary zpos candidate list which is used aggregate all suitable
planes for handling scan-out capable client buffers.
We go over it twice: once to construct it and once to pick-and-choose a
suitable plane based its highest zpos position.
In order to maintain the view order correctly we track current zpos
value being applied to the plane state and use it when trying to place
a view into a plane.
Pass the computed zpos value to be applied to the plane state.

Due to an error in driving GitLab, this commit erroneously contained the
entirety of !267 (zpos support in the KMS backend) squashed into one
single commit, pushed into master.
In order to keep the history clean, this is being reverted; a rebased
version of !267 with the clear individual commits which were already
present will be applied in its place.
This reverts commit 95e3b0deae.
Currently drm-layer supports HDCP1.4 using connector property:
Content Protection. This property if available for a platform, can be
read and set for requesting content-protection.
Also, the patch series [1] adds HDCP2.2 support in drm, and patch [2]
adds support to send udev events for change in connector properties,
made by the kernel.
This patch adds these HDCP connector properties in weston, and exposes
the content-protection support to the client for drm-backend.
It adds the enums to represent 'Content Protection' and 'Content Type'
connector properties exposed by drm layer. It adds a member
'protection' in drm_output_state, to store the desired protection
from the weston_output in the drm-backend output-repaint cycle. This
is then used to write the HDCP connector properties for the drm_heads
attached to the drm_output.
The kernel sends uevents to the user-space for any change made by it
in the "Content Protection" connector property. No event is sent in
case of change in the property made by the user-space.
It means, when there is a change of the property value from "DESIRED"
to "ENABLE" i.e. successful authentication by the kernel, a uevent
will be generated, but in case of userspace requesting for disabling
the protection by writing "UNDESIRED" into the property, no uevent
will be generated.
This patch also adds support for handling new udev events for HDCP
connector property changes. Any such change, triggers change in the
weston_head's current_protection.
