This patch changes the way of how the client-selected sub directory is
communicated to the server. The former opaque session argument is now
passed as last label element, which allows for the flexible tweaking
of this argument by init's session-routing and label-rewriting
mechansims. In particular, it alleviates the need for creating chroot
component instances.
This change requires the following four adaptations at the
configuration level:
- Each file-system session request must now carry a path starting
with / as last session arguments. Hence, <vfs> <fs> nodes that
feature a 'label' attributes must extend the attribute value
with " -> /". For <fs> nodes with no label attribute, "/" is
used as last label argument by default.
- For matching session-routing rules at init's configuration,
the matching of full labels should be replaced by 'label_prefix'
matches, excluding the last (path) argument.
- Wherever a label of a file-system session is rewritten by using
init's 'label' attribute of a <parent> or <child> target node,
the new attribute 'identity' should be used instead. This replaces
the identity part of the label while preserving the client's
directory argument.
- Analogously to the matching of session-routing rules, server-side
policy-selection rules that formerly matched a concrete 'label'
must be changed to match a 'label_prefix' instead.
As a good practice, 'label_prefix' values should end with " ->" if
possible, which clearly delimits the identity part of the label
used by the matching.

This patch changes the window-layout format to support the rectangular
clipping of windows at screen boundaries. The new <boundary> node defines
the clipping boundary for the windows listed within the node. Boundaries
are expected to be disjoint. In the example below, the "vbox" window is
placed partially outside the screen area of "screen_2".
<window_layout>
<boundary name="screen_1" xpos="0" ypos="0" width="640" height="480">
<window id="1" title="launchpad" xpos="10" ypos="140" width="400" height=">
</boundary>
<boundary name="screen_2" xpos="640" ypos="0" width="800" height="600">
<window id="2" title="vbox" xpos="520" ypos="52" width="800" height="600">
<window id="3" title="terminal" xpos="650" ypos="72" width="500" height="400">
</boundary>
</window_layout>
The layouter uses boundaries to restrict the visiblilty of windows to
their respective target areas.
Until now, Sculpt relied on the fact that the window-layout ROM had the
same structure as the resize-request ROM. With the addition of the
<boundary> nodes, this is no longer the case. Therefore, the Sculpt
manager generates a dedicated resize-request ROM now.
Issue #5390
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.
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.
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
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
Following the rework of the graphics stack, the decorator inside
Leitzentrale needs more capabilities. This manifests in a log message:
```
[leitzentrale] child "decorator" requests resources: cap_quota=18
```
and the Leitzentrale contents execpt for the log window disappearing
from the display. The Leitzentrale layer can still be toggled using F12.
Increasing the decorator's capability quota appears to solve the issue.
Issue #5356
The recent changes of the GUI stack (proper accounting of cap and RAM
resources by the window manager and nitpicker, output buffered at the
server side) require quota adjustments at various GUI-related places.
Issue #5356
This patch changes the precision of the configuration's motion attribute
to a multiple of 10 ms (centi-seconds). The previous version used steps
of 20 ms. Hence, one needs to adjust existing configurations by doubling
the motion attribute values of the themed decorator.
Issue #5347
This commit streamlines the interaction between the Wifi::Manager
and the wpa_supplicant's CTRL interface.
As user-facing changes it alters some default settings and introduces
new features:
* Every configured network now needs to explicitly have its
'auto_connect' (to be considered an option for joining) attribute
set to 'true' whereas this was previously the default value if the
attribute was not set at all.
* The 'log_level' attribute is added and configures the supplicant's
verbosity. Valid values correspond to levels used by the supplicant
and are as follows 'excessive', 'msgdump', 'debug', 'info', 'warning'
and 'error'. The default value is 'error' and configures the least
amount of verbosity.
* The 'bgscan' attribute may be used to configure the way the
supplicant performs background-scanning to steer or rather optimize
roaming decision within the same network. The default value is set
to 'simple:30:-70:600'. It can be disabled by specifying an empty
value, e.g. 'bgscan=""'.
* The 'verbose_state' attribute was removed alltogether and similar
functionality is now coverted by 'verbose' attribute.
Implementation-wise the internals changed significantly and are
outlined in the following paragraphs.
Formerly the interaction between the manager and the supplicant
was handled in an apparent way where the internal state of each
interaction was in plain sight. This made the flow cumbersome to
follow and therefor each interaction is now confined to its own
'Action' object that encapsulates the ping-pong of commands and
responses between the manager and the supplicant. All actions are
processed in an sequential way and thus there is no longer any
need to defer pending actions depending on the interal state of
the current interaction. Configuration changes as well as events
issued by the supplicant where new actions can be created are
handled in this fashion. Of note are both signal-handlers,
'_handle_cmds' and '_handle_events' respectively.
The state report, which provides the information about the current
state of connectivity to a given wireless network, was dealt with
in the same vein and its handling was spread across the manager
implementation. Again, to make it easier to follow, the generation
of the state report is now purely driven by the 'Join_state' object.
This object encapsulates the state of connectivity and is normally
updated by events issued from the supplicant (see '_handle_events').
It is also incorporated when handling command responses (see
'_handle_cmds').
Handling of timed-actions, like scan and signal quality
update requests, was done by setting a timeout at the Timer session
directly and thus only one timed-action could be pending at any time.
This excluded dealing with timed-actions like connected-scanning
and signal quality polling concurrently. This was changed and now
a One_shot_timeout is used to programm each concurrent timed-action.
For implementing the communication channel for the CTRL interface the
manager and supplicant use a shared memory buffer, the Msg_buffer.
Since the CTRL interface for Genode was implemented using C, some
shenanigans were performed to access the memory buffer. Now the
CTRL interface implementation uses C++ and only exports the functions
required by the supplicant as C. This simplifies the usage of the
Msg_buffer and allows for removing the global functions needed for
synchronizing the Msg_buffer access as those are now part of the
object itself via the 'Notify_interface'.
Fixes#5341.
With this patch, the wm accounts RAM and caps consumed on behalf of its
clients to the respective client's session quota instead of paying out
of its own pocket. This should make the wm resilient against resource
exhaustion and lowers the quota requirements.
Issue #5340
Since the preset contains mesa_gpu-intel, it is specific to the pc
platform. Other platform-specific repos (such as allwinner) may contain
their own preset with the same name. To prevent that Sculpt images use
the wrong preset due to the particular order in the build.conf, we move
the preset into the pc repo.
Fixes#5322
Both keys are physically the same on available keyboards (with varying
labeling). Unfortunately, PS/2 scancode sets and USB HID spec seem to
differ slightly in their interpretation. Therefore, we keep the
driver-level reporting as is but report both as KEY_PRINT in Sculpt,
which allows to use the key(s) for screenshoter rules most prominently.
Also, unify sculpt/event_filter/pc with sculpt_manager.
The default mixer launcher limits the volume to 50%, so raise the
driver's volume to the max to be audible on certain systems where
otherwise audio is barely recognizable.
While there, fix the wrong reporting attribute as well.

This patch disables latency warnings by default. The warnings can be
enabled by setting the 'warning_rate_ms` value to the desired
maximum rate.

Issue #5174
This patch enhances the sculpt manager to drive the system state
and manage the lifecycle of driver components during suspend-
resume cycles.
The new Power options can be found in the System menu. The suspend
and power-off controls are presented only when the acpi-support
option is activated.
Note that the USB controller is hard restarted when resuming from
suspend. Hence, all components that depend on USB are restarted
implicitely.

When the "system" ROM state turns to "suspend",
the S3 state information of the sleep_states ROM are determined and
are used to invoke the privileged Pd::system_control call.

This commit raise various quota to accommodate using a display
resolution of up to '3840x2160' in the static parts, e.g. the
leitzentrale, of Sculpt.
Issue #5174.
The audio launcher configures the 'bsd_audio_drv' component for normal
use where the micrphone selection should work on most Thinkpads.
The mixer launcher configures the 'record_play_mixer' component for
use with the 'audio' launcher and provides also examplary rules for
vbox6 launchers.
The IHD500 is almost a gen9 (skylake) GPU with subtle differences. Linux
maintains a separate feature set `GEN9_LP_FEATURES` for this GPU.
However, foisting the GPU as skylake on the GPU drivers seems to work
quite fine.

This patch replaces the former use of one menu-view component per dialog
by a single menu view presenting all dialogs. This change reduces the
runtime config by about 20%, improves the boot time, and lowers RAM and
CPU usage at runtime.
