This patch fixes the following error message printed by the wm upon the
restart of a decorator.
Error: freeing non-empty slab block"
Error: ID space not empty at destruction time
Fortunately, the error is not critical as the backing store is released
along with the session.
The 'label_suffix=" -> decorator"' rule is weaker than the
more generic 'label_prefix="runtime -> wm"' rule, to the effect that the
decorator is assigned to the "desktop" domain instead of the "decorator"
domain. Replace the 'label_prefix' by the decorator's concrete label
to resolve this ambiguity.
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.

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

Our new U-BOOT for the imx8mp_iot_gate complains about the size
of the device tree being zero bytes. This is because it no longer
provides the kernel boot arguments via ATAGS, but passes them via
by injecting them in the flattened device tree..
This commit adds a minimal dtb file to the FIT image to satisfy U-BOOT.
Issue #5354
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.

When building ELF binaries of core and bootstrap for a run scenario,
also create the *.core.debug file to be able to use the tool/backtrace
utility.

- 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.
Replace the unconditional sleep "until the board comes up" by the
detection of the fastboot-driver message. This shortens the total boot
time and reveals U-boots initial output, e.g., messages reporting
trouble with bringing up the fastboot driver.
The success messages of different versions of the fastboot tool
are printed in different upper/lower case. Tolerate both.
The patch also removes a few superfluous semicolons.
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.

As the initial output of picocom is hardly ever needed, disable it by
default to reduce the log noise. Whenever needed, the output can still
be enabled by specifying the run tool's --log-serial-cmd.
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.
