The 'size_changed' handling remained without effect when the (last)
display re-appears (e.g., back from screen blank) because
'Capture_root::bounding_box()' delivered the '_fallback_bounding_box'
in the intermediate phase where no display was present. Unfortunately,
'Capture_root::visible()' failed to apply the same logic. This patch
makes 'visible()' consistent with 'bounding_box()'. It has the
welcome effect that nitpicker remembers the pointer position during
the dark phase.
Fixes#5397
GCC 12 tree-loop-distribute-patterns generates false warnings of
-Warray-bounds, -Wstringop-overflow, or -Wstringop-overread in memcpy()
and memcpy_cpu() in static/inline cases for code that obviously prevents
its execution by invariant checking. On -O3, even more warnings are
produced.
This patch fixes the corner case where a call of 'trigger_gui_sync'
unexpectedly did not result in the execution of '_handle_gui_sync'.
When sporadically called (w/o having installed a period sync handler)
in a time window shortly after a previous '_handle_gui_sync' that just
switched back to sporadic mode, the situation was considered as !idle.
So the 'local_submit' was skipped.
The patch fixes the issue by always issuing a 'local_submit' except when
operating in period mode. The '_gui_sync_enabled' state is now driven
only by '_handle_gui_sync' to make the intent more clear.
Fixes#5396
When constructing an Usb::Interface and implicitly corresponding
Usb::Endpoint instances only select endpoints relevant for the
given alternate setting.
The libusb has to be changed to delegate the correct alternate
setting to the constructor too.

On hotplug, the C++ side of the driver now gets just notified,
without any further detection.
On the C++ side, now specific actions are scheduled explicitly, which will be
executed step by step. New appearing actions will be queued and are
not eligible to run before the former actions of the list are processed.
Fixe #5392
config node gracefully. If no mirror is set, ever claim one entry
as the mirrored one. Without this change, the current effect is that
the UI does not allow to merge one of the discrete modes.

Foster the Genode books as a single point of reference for Genode's
documentation. E.g., the Getting-Started section of the "Genode
Foundations" book has long obsoleted doc/getting_started.txt. This
patch also remove long orphaned texts like gsoc_2012.txt. The approach
described in the porting guide has now been replaced by the Goa SDK.
The Genode books can be downloaded at the genode.org website. Like
Genode, they are open source. All text is licensed as CC-BY-SA and

Instead of directly process URBs whenever a USBPacket arrives from
the Qemu ported XHCI layer, send a local signal to the I/O handler,
which will process the requests after leaving certain sensible
code pathes like usb_packet_complete. Otherwise, it might happen
that a packet, which was still marked as being queued gets already
completed, which leads to an assertion and hang of the library.

This prevents the potential corner case where the terminal receives input
at a time when the window has no valid size and _text_screen_surface is
not constructed.
If one of core's threads is causing an MMU fault, dump the
register state and stack backtrace of the faulting stack to
aid debugging.

- add a check to detect if a different thread has
initialized the internal object in the meantime
- remove ENOMEM error since the 'Libc::Allocator'
is not supposed to throw exceptions
- remove init mutex from 'pthread_condattr_init()'
since there is no implicit initialization which
could happen in parallel like with mutex/cond/rwlock
Issue #5386
The VFS server used to respond to any invalid config by exiting.
By disregarding such configurations instead, this patch makes the VFS
server robust against temporary malconfiguration.
When trying to open a file in the Files view with font size set to
Large on 4k screens, the editor's / `text_area`'s `view` child fails to
bump its RAM quota when the editor's default quota is too small.
To mitigate the issue, bump the editor's default quota to 80MiB.
The long-term fix would be for the editor to request more RAM from the
runtime to satisfy the `view` RAM request.

When using the Files view with font size set to Large, the boosted
runtime_view limit of 64MiB is still not enough for 4k screens.
Double the RAM boost limit to 128MiB.

With this commit the fb driver is started on the second CPU on the
MNT Pocket Reform to decouple it from the other components started
on the first CPU during the system's boot-up and mitigates bring-up
issues with this driver that result in an often non-working display.
Issue #5378.
This patch removes the only residual C++ exception from the kernel part
of core, eliminating the risk of the kernel thread trying to enter the
kernel itself via the C++ exception-handling path. When throwing an
exception, __cxa_allocate_exception invokes the cxx_heap, which
synchronizes accesses via a Genode::Mutex. In the contention case,
the blocking of the mutex issues a syscall to pause the caller.
The patch fixes the problem by replacing the exception with a return
value.

Issue #5245
This commit adapts the aperture splitting between the GPU multiplexer
and the display driver where the former now always tries to reserve
32 MiB of aperture space for itself instead of limiting the space
for the display driver. In case the aperture is not large enough
the display driver takes precedence and the GPU service has to make
do with remaining space. In the worst case that renders the GPU
service unusable.
Issue #5377.
Don't try to decide based on the hardware state, in which mode a
connector is used. If a previous configuration failed, e.g. -ENOSPC,
the detection whether the mirrored framebuffer is in use may fail
and the connectors are reported wrongly as discrete.
During modeset traversal take the appropriate lock to synchronize irq and
user task, which may be de-scheduled by Linux code when invoking contrib
code.
Issue #5377
The driver code may allocate framebuffers which do not fit in the aperture.
Trying to use such framebuffer may lead to only partial visible content
on the screen and the rest either black or garbage.
Instead check for this circumstance and deny to use such framebuffers and
release them, since the user would get an unusable/hard to interpret state.
Additionally, release the vma mappings earlier in order to reduce the likelihood
of such un-mappable framebuffers.
Issue #5377
When updating a dialog after a prolonged idle time with no active
animatons, the next _handle_gui_sync would wrongly fast-forward
animations for all the frames passed since the last _handle_gui_sync. On
the PinePhone, this effect is clearly visible when switching between the
main section. The GUI jumps from one state to another instead of
transitioning. This patch solves the issue be resetting '_previous_sync'
when waking up from idle.

Large deployments (e.g., using the Falkon browser) can significantly
inflate the RAM quota of depot_rom. When switching the Sculpt storage
target (using the "Use" buttons), depot_rom is restarted. Right now,
however, it retains its (inflated) quota. It is better to reset the
quota to its initial value to free up RAM that thereby becomes usable
for a different deployment. Otherwise, the depot_rom's resources can be
deflated only by rebooting.
This patch fixes focus-follows-mouse problem reported for Sculpt 24.10
when using no (operational) backdrop.
In the absence of a background, nitpicker wrongly delivered absolute
motion events to the most recently hovered client even after leaving the
client's area to a area occupied by no client. These motion events, in
turn, confused the internal consistency of the window managers
enter/leave tracking.
Fixes#5375
When using the fonts_fs, the geometry of individual glyphs can change
potentially at any time, after having obtained font-global constraints
once. In particular, a glyph can exceed the bounding box of the font
cell. The VFS font utility must take safety precautions against such
violations.
