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.

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.
Issue #5174.
This patch disables latency warnings by default. The warnings can be
enabled by setting the 'warning_rate_ms` value to the desired
maximum rate.
Fixes#5186
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.
genodelabs/genode#5177
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.
Issue #5170
This patch lays the selection of the used storage target into the hands
of the config/manager file. By default, Sculpt selects the target by its
built-in heuristics, probing for a Sculpt partition. However, by
specifying a <target> node, one can explicitly select a storage target.
E.g., for using the 2nd partition of the SATA disk connected to port 1
of the AHCI controller, one can now specify:
<target driver="ahci" port="1" partition="2"/>
For selecting the ram_fs as target:
<target driver="ram_fs"/>
The latter case is particularly useful for custom Sculpt scenarios
deployed entirely from RAM. For such scenarios, add two lines to
your .sculpt file:
ram_fs: depot
manager: use_ram_fs
The first line configures the ram_fs such that the depot is mounted
as a tar archive. The second line configures the sculpt manager to
select the ram_fs as storage target. You can find this feature
exemplified in default-linux.sculpt scenario.
build/x86_64$ make run/sculpt_test KERNEL=linux BOARD=linux
It is worth noting that the configuration can be changed at runtime.
This allows for switching between different storage targets on the fly.
Issue #5166
The new 'manager' config allows for the passing of configuration data the
sculpt manager without the need to modify the config/leitzentrale subsystem.
Issue #5166
This patch harmonizes the driver management between the sculpt manager
and the phone manager by hosting the individual drivers in a new
'Drivers' class with a narrow interface towards 'Sculpt::Main'. The
patch also introduces a clean separation of the 'Board_info' between
features detected at runtime (on PC hardware), statically
known/managed features (phone hardware), and options that can be
toggled at runtime.
With common patterns for managing drivers in place now, this commit
also moves the former runtime/wifi_drv.cc and runtime/nic_drv.cc
code to driver/wifi.h and driver/nic.h. The _drv suffix of the wifi
and nic driver components have been dropped.
Issue #5150
As the NVMe driver was the last remaining driver controlled by the
driver manager, this patch removes the 'drivers -> dynamic' subsystem
along with the driver manager from sculpt/drivers/pc.
Issue #5150
This patch moves the AHCI driver from the 'drivers -> dynamic'
subsystem to the runtime, managed by the sculpt_manager. One
implication of this change is the new need to supplement a device
port number to the 'Storage_target', in addition to the existing
label and partition. Previously, each block device was addressed by
merely a label specified for a parent session. The meanings of the
'Storage_target' elements are now as follows.
- The label corresponds to the driver component providing the storage.
- The port is used as block-session label when opening the session
at the driver.
- The partition(s) denote the partition information contained in
the block session.
Components operating as clients of the AHCI driver (e.g., a file system)
refer to their storage target as <label>-<port>.<partition> when a port
is defined (for AHCI). For drivers w/o ports, like USB storage where
each USB-block driver correponds to only one device, the storage target
is denoted as <label>.<partition>. When no partition table is present,
the '.<partition>' part is omitted.
