In an attempt to pull more of EGLConfig choosing into one place, refactor code
into the new gl_renderer_get_egl_config(). The purpose of this function is to
find an EGL config that not only satisfies the requested attributes and the
pixel formats if given but also makes sure the config is generally compatible
with the single GL context we have.
All this was already checked in gl_renderer_create_window_surface(), but
gl_renderer_create_pbuffer_surface() is still missing it. This patch is
preparation for fixing the pbuffer path.
We explicitly replace visual_id with drm_formats, because that is what they
really are. Only the DRM backend passes in other than NULL/0, and if other
backends start caring about the actual pixel format, drm_format is the lingua
franca.

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.

62626cbfec ensures that the GL render will not render a view's content
to the screen when the surface has requested a higher content-protection
level than the output currently offers.
When the HDCP MR was split into the core content-protection support in !83
and specific DRM support for HDCP in !48 (not yet landed), this opened a
hole where the DRM backend could promote a view to a hardware plane,
even if the output offered a lower protection level than the surface
wanted to enforce.
In the DRM backend, check the desired protection level, and refuse to
promote the view to a hardware plane if the output does not offer
sufficient protection. This will lead to presentation falling back to
the renderer, which may censor the content, reduce quality, etc.

Adds initial grouping for sphinx/breathe for the logging/debugging

not exported) and debug-protocol, specific to the weston
debug protocol.
In latest version of breathe, '\memberof' command is recognized as such.
But it conflicts with '\ingroup' command and can't be used in the same

tagging with '\ingroup' then use '\memberof' command for the functions
that work on that object.
There's also a caveat here: we have objects that are private (opaque)

As described in e10c9f89826bb: "weston-debug: Introduce...", the
subscriber object need further functionality to make use of it.
Current form of the weston-debug protocol would not need this, as it
creates underneath a new subscriber each time a client connects and
subscriptions are created/destroyed automatically with the help of
wayland protocol. For other types of streams, we require to manually
create a subscriber and to subscribe to log scopes.
This patch introduces the ability to create subscriptions, and
implicitly to subscribe to (previously created) scopes.
In the event the scope(s) are not created we temporary store the
subscription as a pending one: a subscription for which a scope doesn't
exist at the time of the subscription. When the scope for which the
subscription has been created we take care to create the subscription as
well.
While at it the documentation bits are modified accommodate the subscribe
method and its further functionality.
Lastly, it removes an unlikely case when a scope is not created so we
avoid any kind of dandling (pending) subscription in case there is
subscription to it. We can only do something about in the destroy part
of the scope.

Adds a minimalistic API for managing the subscription object. The
subscribe functionality will be brought in once we re-organize a bit
weston-debug-stream and split it properly. It extends the logging
context with a linked list of potential subscription and adds a linked
list of subscriptions in the log scope.
This patch represents the start of a logging framework for weston. It's
being built around weston-debug, with the intent to superseded it, and
make weston-debug a client of the framework. Further more the logging
framework should replace current logging handler and allow other types
of streams to be used.
Currently present in libweston under weston-debug we have log scopes, debug
streams and a logging context.
With this patch, two (internal) objects are being added: the concept of
a subscriber and the concept of subscription. The subscription object
is a ephemeral object, implicitly managed which is created each time one
would want to a subscribe to a scope. The scope will maintain a list of
subscriptions and will continue to be explicitly managed.
The streams will use the subscriber object as a base class to extend
upon. By doing so it allows to customize the stream with specific
functions that manipulate the underlaying storage. The subscriber object
will require a subscribe function and specific stream functions and like
the scope, will be explicitly managed.

logind will send a device changed at start of day, prompting a session
active change, but the session will already be active from compositor
creation.
Avoid unnecessary signal emition and drm state invalidation.
The logind launcher sets the session active when the graphics device is
assigned to weston from systemd. Unfortunately 8d23ab78 didnt check whether the
session was already active before setting it active and emitting the session
active signal.
The handler for that signal then proceeds to invalidate the entire graphics
state, causing the next redraw to reconfigure all outputs (to the same routing
as they were already).
This then massively increases the likelihood of trying to configure a crtc that
has a commit already in flight.
Add the old behaviour of only emitting a signal on a changed state.
This avoids the issue for now by reducing the chances of a clash. Future
work will need to fix the issue properly (better handling of state_invalid e.g.
wait for quiescence, better monitoring for crtc usage clashes etc).

Depending on system loading, weston-launcher could drop the drm
master access before the compositor and all the clients receive
the notification. In this case, some commit could be sent to the
drm driver too late and get refused with error EACCES.
This error condition is not properly managed and causes weston to
hang.
Change the return type of start_repaint_loop() and repaint_flush()
from void to int, and return 0 on success or -1 if the repaint has
to be cancelled.
In the callers of start_repaint_loop() and repaint_flush() handle
the return value and cancel the repaint when needed.
In backend-drm detect the error EACCES and return -1.
Note: to keep the code cleaner, this change inverts the execution
order between weston_output_schedule_repaint_reset() and
repaint_cancel().
No need to wait for suspend or for any notification; in case the
weston reschedules a repaint, it will get EACCES again.
At resume, damage-all guarantees a complete repaint.
This fix is for atomic modeset only.
Legacy modeset suffers from similar problems, but it is not fixed
by this change. Since drm_pending_state_apply() never returns
error for legacy modeset, this change has no impact on legacy
modeset.

The protection requested for a given surface, must reach through the

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

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

After this is done, we need to flip the co-ordinates in the Y axis to

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

When using logind launcher, we receive a PauseDevice "gone" message
from logind session management for each device we close while looking
for KMS devices.
Make logind notify the backend of the device add/remove so that the
backend can decide what to do, instead of assuming that if it is a
DRM_MAJOR device the session should be (de)activated. The backend can
then react to its specific device.
Fixes#251

A output repaint loop isn't scheduled beacuse the output repaint_status
is AWAITING_COMPLETION when dmps is turned off in update_complete().
Therefore, the display attached to the output is remain inactive even if
weston wakes up. By going through finish_frame, the output
repaint_status is fixed to correct status.

Move the DRM-backend into a new sub-directory to make it stand out from
libweston core. This facilitates splitting drm.c into more files later.
vaapi-recorder is used only by DRM-backend, move that too.
libbacklight is used only by DRM-backend and a manual test program, and is
moved as well.

Right now only used by the DRM-backend, but there is a test program that should
use this as well.
This helps with building the test program and moving DRM-backend into a
subdirectory.

Rather than having fbdev and drm backends include the libinput files ad hoc,
wrap them in a static library. Using the dependency object for that helper
library will then automatically pull in any necerray include dirs for the
users.
This helps with moving the backends into subdirectories.

The printf() format specifier "%m" is a glibc extension to print
the string returned by strerror(errno). While supported by other
libraries (e.g. uClibc and musl), it is not widely portable.
In Weston code the format string is often passed to a logging
function that calls other syscalls before the conversion of "%m"
takes place. If one of such syscall modifies the value in errno,
the conversion of "%m" will incorrectly report the error string
corresponding to the new value of errno.
Remove all the occurrences of the specifier "%m" in Weston code
by using directly the string returned by strerror(errno).
While there, fix some minor indentation issue.

Making this into a dependency object not only carries the .c files with it, but

This is an installed public header, and without the subdir would surely

The backend headers are renamed from compositor-foo.h to backend-foo.h to
better describe their purpose. These headers are public libweston API for each
specific backend.
The headers will also be used like
#include <libweston/backend-drm.h>
instead of
#include <compositor-drm.h>
to give them a more explicit namespace.

The main idea is to make libweston users use the form
#include <libweston/libweston.h>
instead of the plain
#include <compositor.h>
which is prone to name conflicts. This is reflected both in the installed
files, and the internal header search paths so that Weston would use the exact
same form as an external project using libweston would.
The public headers are moved under a new top-level directory include/ to make
them clearly stand out as special (public API).

This patch sets up the stage for similarly renaming compositor.h which will
justify this. That patch will be big, so moving timeline-object.h first makes
it easy to see the changes to the build and install directives.
This and all the following moves essentially break the API, so libweston major
is bumped.

With the addition of patch 433f4e77b7 we display the same view id (0)
for every view as we're modifying the local variable.
Displaying sub-surfaces based views is also problematic. The caller need
to modify the view number as well, so we instead we pass the address as
to allow that to happen. Otherwise we end up repeating the same number
for views without sub-subrfaces once those have been printed.

All the GBM code is unconditional in compositor-drm.c, so while disabling the
