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.

Issue #5245
When using the depot/build tool with the 'REBUILD=' argument as done by
the run tool's --depot-auto-update feature, the depot/build tool now
checks that an existing bin archive was indeed created via the src and
api archives present in the depot for the given version. This addresses
consistency issues when switching between different git branches that
refer to the same depot versions but with different content.
Fixes#5379
This patch records the content hashes of the src and api ingredients
used for creating a bin archive. This information allows for the
detection of possible inconsistencies between a bin archive and its
corresponding src archive within the depot.
Issue #5379
When extracting depot archives from the source tree, retain the content
hash of the extracted information along the archive in <version>.hash
file. The .hash files of src and api archives become thereby usable for
checking the consistency of bin archives with their ingredients.
Issue #5379
With --depot-auto-update enabled, the run tool calls the depot/create
tool, which in principle may fail. In this case, print a diagnostic info
instead of a backtrace.
Issue #5379
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.
Fixes#5374
Board-specific repositories must appear before generic repositories
(i.e., gems) in 'REPOSITORIES' to select board-specific sculpt/
configuration snippets over the defaults provided by gems. When listing
the board-specific repositories last, Sculpt images for the PinePhone or
MNT Reform may wrongly include launchers and presets of the PC version.
Swapping a 4k monitor between discrete and mirror mode will consume
temporarily at least 32M * 2 (3840 * 2160 * 4 Bytes), so that the
default value of 64M for the aperture is insufficient in addition to
interal display on a notebook. The commit mitigates that the
i915_gem_evict_for_node unimplemented error does not trigger immediately.
Issue #5356
In setups with 3 or more displays, allow the un-merging of connectors
only for the last mirrored connector. Otherwise, the operation would
implicitely change the order of connectors because the new discrete
connector needs appear after all merged connectors.
Issue #5286
The access-point-list hovered state prevents preseting the available
scan results, which currently can happen unintentionally. This commit
hot-wires the hover handling and thus will always show and update the
list. New scan results are received every few seconds and it could
happen that the list changes while the user selects a network (that's
what the original implementation guards against).
Issue #5369.
Since the panorama depends on the config, nitpicker needs to re-evaluate
the validity of the pointer position after each reconfiguration. If the
pointer position is no longer visible, pick a new visible one.
Issue #5352
This patch explicitly handles the unplugging of displays, avoiding the
use of stale connectors for defining the panorama. It also makes the
import of the connectors model robust against intermediate states
reported by the driver (a connector reported as connector but without
any mode), and discards the use of any information of non-present
connectors as merge info.
Issue #5286
The minimum width/height of a dialog is not specified in the dialog ROM
but in the menu_view configuration. So the regular dialog-ROM update
handling fails to captures dynamic changes of the minimum w/h. In
Sculpt, the panel would not always adjust immediately to a new screen
size.
This patch triggers a dialog update when detecting such configuration
changes (min w/h, opaqueness, background color).
Issue #5370
This patch places the leitzentrale GUI always at the pointer-at display
instead of filling the entire panorama. This ensures that the complete
leitzentrale GUI is always visible.
Fixes#5370
If the fb driver is configured to use discrete displays, sculpt now
automatically generates a panorama configuration for nitpicker that
shows all displays side by side. The effective nitpicker config is
now located at config/managed/nitpicker.
The automatism takes effect only when nitpicker's <capture> node
in config/nitpicker is empty. Hence, the managed panorama can be
overridden by a manually managed panorama.
Issue #5286
This patch handles the case where a mode change happens in-between
session creation and the registration of the mode-signal handler,
which can result in a sporadic loss of response to mode changes.
Noticed while working on issue #5286.
This patch add a configuration dialog in the intel_fb node of the
component graph. The dialog displays a list of present displays labeled
after their respecive connectors. A mode can be selected for each
connector when clicking on the connector entry.
In-between the entries there are two buttons. The connect button is
toggle that defines whether the two adjacent entries are mirrored.
It is enabled by default so that all new connectors participate in
the mirroring. By untoggling the last enabled connect button, the
entry below the button becomes a discrete (non-mirrored) display.
A swap button allows for changing the order of the list, which has
to effects. First, the resolution of the very first entry defines
the size for mirrored display. So be changing the order of mirrored
displays, one can pick the preferred screen size. Second, the order
of discrete displays defines the layout of the panorama from left to
right. (the panorama config is not part of this commit though)
Note that there is currently no safety net against locking oneself
out of all displays. E.g., one can make Sculpt unusable by manually
disabling each display, or by selecting modes not properly handled by
the connected monitor. In the future, we may add a confirm button with
a timeout to roll back such unfortunate settings.
