5cfe03c863 libweston: Add content-protection protocol implementation
This patch adds the content-protection protocol implementation, to
enable a weston client application to request for content-protection
for its content via HDCP.

4b6e73d617 libweston: Add support to set content-protection for a weston_surface
The protection requested for a given surface, must reach through the
weston_surface::pending_state, in the commit-cycle for the
weston_surface, so that it gets updated in the next commit.

As some protection is requested for a given weston_surface, it means
protection must be set for each of the outputs which show the surface.

While setting the protection of a weston_output, care must be taken
so as to avoid, degrading the protection of another surfaces, enjoying
the protection. For this purpose, all the weston_surfaces that are
shown on a weston_output are checked for their desired protection.
The highest of all such desired protections must be set for the
weston_output to avoid degrading of existing protected surfaces.
A surface requesting protection for a lower content-type can still be
provided protection for a higher type but the converse cannot be
allowed.

This patch adds support to set content-protection for a suface, which
inturn sets the content-protection for each of the outputs on which
it is shown, provided, none of the existing surface's protection
request is downgraded.

4f64ff8b2f libweston: Compute current protection for weston_output and weston_head
The actual protection status for a given weston_head depends upon the
corresponding drm_head's connector HDCP properties. On the other hand,
the actual protection for a weston_output is the minimum of the
protection status of its attached heads.
As a head's protection changes, the current protection of the output
to which the head is attached is recomputed.

This patch adds the support to keep track of the current
content-protection for heads and the outputs.

2690a77088 libweston: Add support to set content-protection for a weston_output
For making an output secure, the content-protection should be set for
each of head attached to that output. So whenever the protection for
a weston_output is desired, it means that protection is desired for
each of the weston_head attached to that weston_output.

This patch introduces a new enum in libweston to represent the
requested/current protection statuses, equivalent to the type enum
defined by the weston-secure-output protocol. The new enum helps to
extend the content-protection status and requests to libweston and
the backends.
This patch also adds a new member desired_protection to store the
desired protection for an output in weston_output.

06aeb0eae0 protocol: Add content-protection protocol
This protocol allows a client to ask the compositor to only allow it to
be displayed on a "secure" output. This initial version of the protocol
supports HDCP.

This is loosely based on the chromium secure-output protocol [1].

This protocol is mostly useful for closed system, where the client can
trust the compositor, such as set-top boxes. This is not a way to
implement any kind of Digital Rights Management on desktops. The
compositor would be free to lie to the client, anyway.

6ef2d45a2d ivi-layout: unmap desktop surfaces in ivi_view_destroy()
weston_desktop_surface_unlink_view() does now call weston_view_destroy() so the
weston_view is not destroyed here. This is a problem because the view remains in
the weston_layer view_list. If ivi_view_destroy() is called from
ivi_layout_surface_destroy() and the view list is rebuilt in the 'removed'
signal, then the list gets corrupted when the view is destroyed immediately
afterwards.
Fix this by calling weston_view_destroy() unconditionally for all view.

64a92265e8 doc/sphinx: No need for doxygen custom target
Unfortunate left over which was not removed once we had the script in
place to regenerate the documentation. A side-effect was the fact that
we still ran the script even if 'docs' target was called, effectively
nullifying the fact that 'docs' target was ran at all. For instance,
'install' would've been executing the script even if 'docs' target
was called before.

This removes the doxygen_target entirely and the depends of sphinx
target on it, makes building and installing docs a bit faster.

Pads launchers with the empty space that used to be around them. Moving

has more padding at its start to look nice.

Moves the clock to the right edge with same padding. Keeps one of the

never read. Horizontal panel position centers the clock.

Sets text in the panel, meaning tooltips and the clock, to consistent 14
units of the default system font at 85% of the max brightness, so it's

df2095fa35 gl-renderer: Support EGL_KHR_partial_update
partial_update is an EGL extension which allows us to inform the driver
ahead of time the limits of the areas we'll be writing to. This helps
performance for GPU hardware which renders into a local tile buffer:
informing the driver of the rendering extents means it can avoid
fetching unchanged tiles into the tile buffer and subsequently writing
them out.

The extension complements rather than replaces EGL_EXT_buffer_age (used
before partial_update to know which areas we need to update) and
EGL_KHR_swap_buffers_with_damage (used after partial_update to inform
the winsys of the changed region).

Note however that partial_update deals in buffer-damage regions ('what
has changed since the last time I used _this_ buffer?'), whereas
swap_buffers_with_damage deals in surface-damage regions ('what has
changed since the last time I rendered?'). An explanatory diagram can be
found in the specification:
https://www.khronos.org/registry/EGL/extensions/KHR/EGL_KHR_partial_update.txt

55bcb93fef gl-renderer: Use helper for conversion to EGL rects
eglSwapBuffersWithDamage has to convert a damage region from Weston's
global co-ordinate space, into the co-ordinate space for EGL rendering
into a buffer for that output.

The conversion from the global co-ordinate space in logical pixels to
the output space in buffer pixels is slightly long and error-prone,
involving translating by the output's offset within the global
co-ordinate space, multiplying by output scale, and also translating to
allow for any borders we paint around the output.

After this is done, we need to flip the co-ordinates in the Y axis to
account for the lower-left-origin co-ordinate space used by EGL.

Since we want to reuse this for partial_update, but using a different
source region, extract this conversion into a well-commented helper we
can reuse.

Also, add tag symbols related to 'weston_head'.

The bridge between sphinx and doxygen (breathe) has a useful directive:
doxygengroup. By using it we can scoop out symbols we'd like to display

At the same time some bits of the code has been using '\memberof' (a
doxygen command useful in C code to establish class like
relationship between objects and functions) but this seems not to be
recognized by the sphinx bridge.

Until we find a better solution, we replace '\memberof' command with
'\ingroup' one as to tag the symbols with an "object". This patch does
that for 'weston_head' object.

bbf6ea0b4f build: Add sphinx/breathe support for generating documentation
This is adds basic configuration files for doxygen and for breathe,
which is a doxygen-to-sphinx bridge that can document C symbols.

Breathe is configured with default project 'weston' and implicitly adds
:members: and :undoc-members: to breathe configuration options.
This allows a shorter way to call breathe directives without the need
specify the project and also to display implicitly all the members,
documented or not.

A 'docs' run_target to force the docs to be re-built has been added.
Initially (the first time the build system is ran) the documentation
will automatically be built, but later re-builds will require the use of
the 'docs' target. This avoid further delays in building weston but in
the same time allows the possiblity to update/improve the documentation
bits to those who want that.

87fab1ca4e compositor-drm: Only assign planes with atomic
Without atomic modesetting, we have no way to know whether or not our
desired configuration is usable. It might fail for a number of reasons:
scaling limits, bandwidth limits, global resource (e.g. decompression)
unit contention, or really just anything.

Not only this, but there is no good way to ensure that our configuration
actually lands together in the same refresh cycle - hence the 'atomic'
in atomic modesetting. Some drivers implement a synchronously blocking
drmModeSetPlane, whereas others return immediately. Using overlay planes
can thus decimate your framerate.

The pre-atomic API is not extensible either, so we need numerous out
clauses: fail if we're cropping or scaling (sometimes), or changing
formats, or fencing, or ...

Now we've had atomic support stable for a couple of releases, just
remove support for doing anything more fancy than displaying our
composited output and a cursor with drivers which don't support atomic
modesetting.

Support for using overlay planes was already disabled by default when
using the legacy API, and required a debug key combination to toggle it
on by flipping the sprites_are_broken variable. We can ensure that we
never try to use it on legacy by simply ignoring the hotkey when in
legacy mode.
