When a kernel-mode-setting driver loads it will trigger an add udev event
for /dev/dri/card0, followed by one udev change event per connector on the
card. This means that after our initial probe of the card,
create_heads_for_active_connectors is called a number of times for all the
udev change events.
After the initial enum our outputs array will contain active entries for
all connected displays. Meaning that the first loop in
create_heads_for_active_connectors would call get_output_info for
these outputs. Under the hood this does a number of ioctls and especially
the drmModeGetConnector call can be quite expensive.
Then in the second loop create_heads_for_active_connectors would call
get_output_info for all connectors, including for the once which were
checked in the first loop.
There is no reason why we cannot check if active connectors in the
old outputs array have changed when we are calling get_output_info for
all connectors to build the new array. This avoids unnecessarily making
the expensive get_output_info call twice for active connectors in the
old outputs array.

Commit f9e376797a ("ply-device-manager: Consume all events in one go")
changed ply-device-manager to consume all pending udev events in one go
instead of consuming only 1 and then returning back to the mainloop.
The idea here was to avoid the overhead of returning back to the mainloop,
doing the poll again, seeing more events were pending and then re-enter
ply-device-manager.
In retrospect this is not a good idea. Systemd waits for oneshot units
like plymouth-switch-root.service to finish and this can block the boot.
Specifically plymouth-switch-root.service must complete before systemd in
the initrd will exec the systemd from the real rootfs. This means that
systemd inside the initrd waits for the:
ExecStart=-/usr/bin/plymouth update-root-fs --new-root-dir=/sysroot
Command to complete, if this command runs while we are consuming udev
events from the graphics card (which sends a change event per probed
connector during the initial probe), then plymouth will not send the ack
to the plymouth boot-client (completing the ExecStart) until all udev
events are consumed.
On my main workstation with i915 graphics and 2 HDMI connected FHD monitors,
this delays the actual switching of the root by 1.9 - 2.1 seconds,
because the re-enumaration of the connectors in the drm plugin takes
about 0.4 seconds per run.
Other upcoming changes will greatly reduce that 0.4 seconds, but still
returning to the main-loop after a single udev event so that we can
answer any waiting boot-clients ASAP is a good idea.
This reverts commit f9e376797a.

All plymouth's systemd unit files are meant to only run once, either during
boot or during shutdown/restart.
Certain events cause systemd to recheck the dependency try between systemd
units. Systemd had a bug before the 245 release which caused this check to
sometimes not restart exited services for which the dependencies are met.
Systemd 245 fixes this, this is causing problems with plymouth.
When the conditions are met for systemd to recheck the dependencies;
and the plymouthd started by plymouth-start.service has exited;
then systemd will restart the plymouth-start unit, causing plymouthd to
take over tty1 after boot. This is causing various problems, also see:
https://bugzilla.redhat.com/show_bug.cgi?id=1803293
Since all plymouth's systemd units are intended to run only once, they
all should be marked as remaining after exit by adding:
"RemainAfterExit=yes" to them. This causes systemd to still consider them
running after e.g. plymouthd has exited, as long as they have started
successfully. This fixes systemd restarting plymouth's units when it
should not do so.

We try to start the end animation early based on our progress accounting
but this is highly unreliable because e.g.:
-It counts time to enter the diskcrypt passwd as normal boot time, while
this varies wildly from boot to boot
-Boot times for laptops can differ significantly between docked / undocked
state
Between gdm calling /bin/plymouth deactivate and the drm plugin's deactivate
method getting called there can be e.g. 2.1 seconds (from a random boot),
with a theoretical maximum of 3 seconds (2 seconds to finish the throbber +
1 second for the end animation).
On a modern system userland boot should be able to finish in say 5 seconds,
making gdm wait an additional 1 - 3 seconds for deactivation is a huge amount
of extra wait time!
This commit adds a new "UseEndAnimation" option to the two-step plugin,
which defaults to true. Setting this to false makes deactivation immediate.
This works nicely with the spinner (and bgrt) themes since we do not really
do anything special in the end animation there anyways and since we fade-over
into gdm things will still look ok, while shaving a signifcant chunk of our
boot time.

The script plugin currently allows pixel buffers to be resized and

the buffer, which is necessary for images that cannot be stretched,
such as progress bars with gradients.
This commit adds that feature as a new Crop method.
One case where the various widgets are being freed is the pixel-display-s
being removed because of a monitor being hot(un)plugged. When the monitor
configuration changes ply-device-manager removes all old pixel-displays
and then adds the pixel-displays from the new config.
Calling ply_pixel_display_draw_area on a pixel-display which is about to be
freed is a bad idea, if the monitor was actually unplugged this leads to
various sort of errors, including crashes in some cases.
ply-throbber is the only (older) widget which does a redraw on free,
this likely was not noticed until now because typically the throbber
will already have been stopped on free.
This commit adds a redraw parameter to ply_throbber_stop_now and sets
this to false when calling ply_throbber_stop_now from ply_throbber_free.
This fixes plymouth sometimes crashing when monitors are hot(un)plugged

Doing a ply_trace both before and after the disconnect handler, which

The boot server uses a disconnect handler which closes the fd, this
causes deleting the fd from the epoll watch list to fail with an EBADF
error. Since the fd was closed it was already removed from the epoll
watch list, so the failure is harmless, silence these errors getting logged
to the debug logs.

plymouth calls `grantpt()` when setting up the pseudoterminal it uses
for boot logging and console broadcasting. `grantpt()` traditionally
sets up the access permissions and file mode of the created slave
pseudoterminal device node.
That call is unnecessary for two reasons:
1. The kernel automatically sets up the correct permissions at open
time on modern Linux.
2. plymouthd runs as root anyway
Furthermore, it seems like, for some unknown reason, the call may be
interfering with the shutdown process.
This commit drops the call, since it's unnecessary, and potentially
even problematic.
commit 04102125 removed a feature, only several versions of
GDM relied on for doing the splash to login screen transition.
but it missed a few spots in the build goo and documentation. So
this commit does another pass to fully clean up any lingering
references to obsolete GDM transition code.
Both handlers on_deactivate() and on_quit() sets the handler
on_boot_splash_idle() using the helper ply_boot_splash_become_idle().
That helper creates a new trigger and it stores it alongside the handler
in its context. The helper asserts if the trigger is set (i.e. a handler
is pending already).
None of the handlers on_deactivate() and on_quit() check if the handler
on_boot_splash_idle() is set already.
There is a race condition that leads to the situation in which the
assertion is false and causes plymouthd to signal itself with SIGABRT
and die.
First, a client sends the request deactivate to the daemon that creates
a trigger for the idle handler. Then, the trigger is still pending while
another client sends the request quit to the daemon that tries to create
a second trigger and die because of the assertion.
This commit adds the new state variable splash_is_becoming_idle that is
checked before calling the helper ply_boot_splash_become_idle() to avoid
to call it twice. The state variable is set by the caller after it calls
the helper ply_boot_splash_become_idle(). It is cleared by the handler
on_boot_splash_idle() after the splash becomes idle.

We do not want to set our buffer as scanout source before it has been
drawn to by the splash, to avoid a flicker caused by us installing a
black buffer for scanout.
To avoid this, flush_head() only calls reset_scan_out_buffer() if the buffer
for the head has updated_areas, iow if it already has been drawn to.
Our ply_pixel_buffer_fill_with_color() call in ply_renderer_head_new()
causes updated_areas to be non-empty, triggering a reset_scan_out_buffer()
call before the buffer has been drawn at least once.
This commit fixes this by clearing the updated_areas after the
ply_pixel_buffer_fill_with_color() call.

On devices which have their LCD panel mounted 90° rotated with the left-side
of the physical LCD-panel up (at the top), we were using the wrong offset
for placing the bgrt graphics. We were directly using y_offset from the bgrt
as x_offset, but y_offset is from the top of the physical LCD which in this
case is the right side of the panel as seen by the user. Where as our x_offset
is defined to have 0 at the left side.
This commit fixes this issue by flipping the y_offset value on these panels
before using it as our x_offset.
This fixes the logo jumping 6 pixels to the left on an Asus T100HA, which
has such a panel and uses a bgrt y_offset of 512, which results in a flipped
y_offset of 518 (for some reason the log is not entirely centered triggering
this problem).
