This patch completely removes the Raspberry Pi backend and the renderer.
The backend and the renderer were written to use the proprietary
DispmanX API available only on the Raspberry Pi, to demonstrate what the
tiny computer is capable of graphics wise. They were also used to
demonstrate how Wayland and Weston in particular could leverage hardware
compositing capabilities that are not OpenGL. The backend was first
added in e8de35c922, in 2012.
Since then, the major point has been proven. Over time, support for the
rpi-backend diminished, it started to deteriorate and hinder Weston
development. On May 11, I tried to ask if anyone actually cared about
the rpi-backend, but did not get any votes for keeping it:
https://lists.freedesktop.org/archives/wayland-devel/2016-May/028764.html
The rpi-backend is a good example of how using an API that is only
available for specific hardware, even more so as it is only available
with a proprietary driver stack, is not maintainable in the long run.
Most developers working on Weston either just cannot, or cannot bother
to test things also on the RPi. Breakage creeps in without anyone
noticing. If someone actually notices it, fixing it will require a very
specific environment to be able to test. Also the quality of the
proprietary implementation fluctuated. There are reports that RPi
firmware updates randomly broke Weston, and that nowadays it is very
hard to find a RPi firmware version that you could expect to work with
Weston if Weston itself was not broken. We are not even sure what is
broken nowadays.
This removal does not leave Raspberry Pi users cold (for long), though.
There is serious work going on in implementing a FOSS driver stack for
Raspberry Pi, including modern kernel DRM drivers and Mesa drivers. It
might not be fully there yet, but the plan is to be able to use the
standard DRM-backend of Weston on the RPis. See:
http://dri.freedesktop.org/wiki/VC4/
The rpi-backend had its moments. Now, it needs to go. Good riddance!

This patch enhances the panel clock by adding a config file
option which can be used to either disable the clock or make
it also show seconds in the current clock format.
v2: Implement suggestions from Pekka:
- Include Signed-off-by
- Coding style fixes
- Implement clock widget allocation by using
width from cairo_text_extents
- Highlight config option values in man page
v3: Implement suggestions from Pekka and Bryce:
- Use CLOCK_FORMAT_* instead of FORMAT_* in the enum
- Switch to using fixed clock widget size instead
of one returned from cairo_text_extents
- Fixes to config option highlighting in the man page
v4: Implement more suggestions from Pekka and Bryce:
- Improve patch changelog
- Move the check for CLOCK_FORMAT_NONE into the
caller function
- Fix a memory leak in panel_create introduced by
previous revision of this patch

(Derek Foreman changed the prototype for switch_vt_binding to
have a weston_keyboard * instead of weston_seat *. The pointer
wasn't used, so this is just a warning fix.)
This is a follow-up for the patch that removed weston-screensaver. The
aim is to clean up shell.c a little by removing non-essential
components. Vanilla Weston desktop is only a demo, external projects are
encouraged to create user-friendly desktop environments.
The support for launching a screensaver client and the protocol bindings
are removed. With them, all related configuration options are removed,
and the manuals are updated accordingly.
The screensaver protocol definition is left in desktop-shell.xml for
posterity.
This does not affect Weston's or desktop-shells ability to put screens
to sleep after inactivity. The inactivity timer continues to operate as
before. Also screen locking is unaffected.

We have the Weston command line option '--no-config' which is meant to
prevent loading weston.ini at all. It works for Weston itself, but it
does not work for any clients that also want to read weston.ini.
To fix that, introduce a new environment variable WESTON_CONFIG_FILE.
Weston will set it to the absolute path of the config file it loads.
Clients will load the config file pointed to by WESTON_CONFIG_FILE. If
the environment variable is set but empty, no config file will be
loaded. If the variable is unset, things fall back to the default
"weston.ini".
Note, that Weston will only set WESTON_CONFIG_FILE, it never reads it.
The ability to specify a custom config file to load will be another patch.
All programs that loaded "weston.ini" are modified to honour
WESTON_CONFIG_FILE.

This timer delays the output_repaint towards the end of the refresh
period, reducing the time from repaint to present.
The length of the repaint window can be set in weston.ini.
The call to weston_output_schedule_repaint_reset() is delayed by one
more period. If we exit the continuous repaint loop (set
output->repaint_scheduled to false) in finish_frame, we may call
start_repaint_loop() unnecessarily. The problem case was actually
observed with two outputs on the DRM backend at 60 Hz, and 7 ms
repaint-window. During a window move, one output was constantly falling
off the continuous repaint loop and introducing additional one frame
latency, leading to jerky window motion. This code now avoids the
problem.
Changes in v2:
- Rename repaint_delay_timer to repaint_timer and
output_repaint_delay_handler to output_repaint_timer_handler.
- When computing the delay, take the current time into account. The timer
uses a relative timeout, so we have to subtract any time already gone.
Note, that 'gone' may also be negative. DRM has a habit of predicting
the page flip timestamp so it may be still in the future when we get the
completion event.
- Do also a sanity check 'msec > 1000'. In the unlikely case that
something fails to provide a good timestamp, never delay for more than
one second.

This patch adds a new weston.ini key, gbm-format, to the [core] section.

The new key startup-animation in the [shell] section lets you
control the startup animation. Default is fade, but with this patch
we can also do none, which just show the desktop as fast as possible.
Scale-crop mode scales the wallpaper to tightly fill the whole output,
but preserving wallpaper aspect ratio. If aspect ratio differs from the
output's, the wallpaper is centered cutting it from top/bottom or
left/right.
Add this to the weston.ini man page, and explain all three modes.

This set of changes adds support for searching for a given config file
in the directories listed in $XDG_CONFIG_DIRS if it wasn't found in
$XDG_CONFIG_HOME or ~/.config. This allows packages to install custom
config files in /etc/xdg/weston, for example, thus allowing them to
avoid dealing with home directories.
To avoid a TOCTOU race the config file is actually open()ed during the
search. Its file descriptor is returned and stored in the compositor
for later use when performing subsequent config file parses.
