PRESENTATION_FEEDBACK_KIND_ZERO_COPY is a flag that needs to be set for
each surface separately. Some surfaces may be zero-copy (as defined by
Presentation feedback) while some are not.
A complication with Weston is that a surface may have multiple views on
screen. All copies (views) of the surface are required to be zero-copy
for the ZERO_COPY flag to be set.
Backends set per-view feedback flags during the assing_planes hook, and
then Weston core collects the flags from all views of a surface.

Change weston_output_finish_frame() signature so that backends are
required to set the flags, that will be reported on the Presentation
'presented' event. This is meant for output-wide feedback flags. Flags
that vary per wl_surface are subject for the following patch.
All start_repaint_loop functions use the special private flag
PRESENTATION_FEEDBACK_INVALID to mark, that this call of
weston_output_finish_frame() cannot trigger the 'presented' event. If it
does, we now hit an assert, and should then investigate why a fake update
triggered Presentation feedback.
DRM:
Page flip is always vsync'd, and always gets the completion timestamp
from the kernel which should correspond well to hardware. Completion is
triggered by the kernel/hardware.
Vblank handler is only used with the broken planes path, therefore do
not report VSYNC, because we cannot guarantee all the planes updated at
the same time. We cannot set the INVALID, because it would abort the
compositor if the broken planes path was ever used. This is a hack that
will get fixed with nuclear pageflip support in the future.
fbdev:
No vsync, update done by copy, no completion event from hardware, and
completion time is totally fake.
headless:
No real output to update.
RDP:
Guessing that maybe no vsync, fake time, and copy make sense (pixels
sent over network). Also no event that the pixels have been shown?
RPI:
Presumably Dispmanx updates are vsync'd. We get a completion event from
the driver, but need to read the clock ourselves, so the completion time
is somewhat unreliable. Zero-copy flag not implemented though it would
be theoretically possible with EGL clients (zero-copy is a per-surface
flag anyway, so in this patch).
Wayland:
No information how the host compositor is doing updates, so make a safe
guess without assuming vsync or hardware completion event. While we do
get some timestamp from the host compositor, it is not the completion
time. Would need to hook to the Presentation extension of the host
compositor to get more accurate flags.
X11:
No idea about vsync, completion event, or copying. Also the timestamp is
a fake.

When a function is named drm_output_FOO(), you'd expect it to take a

drm_output_prepare_scanout_view(), drm_output_prepare_overlay_view(),

Additionally convert drm_sprite_crtc_supported() from weston_output to

The current parser directly reads a BOOLEAN on the PropertiesChanged
signal for 'Active' properties. However, all property-values are packed in
a VARIANT, otherwise, we wouldn't know the type. Fix the parser to recurse
into the variant before reading the boolean.
To avoid such bugs in the future, we extract the 'Active' parser into a
helper function parse_active(), which is then shared between the
PropertiesChanged and Get handlers.

logind: delay wakeup until DRM-device is resumed
However, the other compositor backends do not use DRM, so logind-util will
never get notified about any DRM device. Therefore, we have to forward the
Active=true change immediately.
This commit fixes logind-util to take sync_drm as argument. If it is true,
we do DRM-device synchronisation, otherwise we don't.

Logging is activated and deactivated with the debug key binding 't'.
When activated, it creates a new log file, where it records the events.
The log file contains events and detailed object information entries in
JSON format, and is meant to be parsed in sequence from beginning to the
end.
The emitted events are mostly related to the output repaint cycle, like
when repaint begins, is submitted to GPU, and when it completes on a
vblank. This is recorded per-output. Also some per-surface events are
recorded, including when surface damage is flushed.
To reduce the log size, events refer to objects like outputs and
surfaces by id numbers. Detailed object information is emitted only as
needed: on the first object occurrence, and afterwards only if
weston_timeline_object::force_refresh asks for it.
The detailed information for surfaces includes the string returned by
weston_surface::get_label. Therefore it is important to set
weston_timeline_object::force_refresh = 1 whenever the string would
change, so that the new details get recorded.
A rudimentary parser and SVG generator can be found at:
https://github.com/ppaalanen/wesgr
The timeline logs can answer questions including:
- How does the compositor repaint cycle work timing-wise?
- When was the vblank deadline missed?
- What is the latency from surface commit to showing the new content on
screen?
- How long does it take to process the scenegraph?

When printing out logs from Weston's actions, mainly for debugging, it
can be very difficult to identify the different surfaces. Inspecting
the configure function pointer is not useful, as the configure functions
may live in modules.
Add vfunc get_label to weston_surface, which will produce a short,
human-readable description of the surface, which allows identifying it
better, rather than just looking at the surface size, for instance.
Set the label function from most parts of Weston, to identify cursors and
drag icons, and panels, backgrounds, screensavers and lock surfaces, and
the desktop shell's application surfaces.
v2: renamed 'description' to 'label', so we get
weston_surface_set_label_func().
