This style is used by the upcoming phone version of Sculpt for GUI
elements that are supposed to stand out a little bit more than the
regular frame style.
This patch enhances menu_view with the optional configuration attributes
'opaque' and 'background'. Setting 'opaque' to "yes" suppresses the use
of the alpha channel at the GUI session. This improves the drawing
performance by 20% on the PinePhone. Since the menu_view uses the
gems/gui_buffer.h utility, the 'Gui_buffer' received a new 'Alpha'
argument at construction time.
The 'background' attribute can be specified to define the reset color of
the GUI buffer. It alleviates the need to create a frame widget for the
top level.
The patch also switches the optimization level for compiling menu_view
to -O3, which increases the drawing performance on the PinePhone by 30%.
Fixes#4592
This change increases the quota to allow the use of bigger fonts, and
tweaks the style such that the keyboard gets a decent appearance on the
PinePhone's 1440x720 display.
This patch adds principle support for using a USB-net modem as
mobile-data uplink. The change is motivated by the upcoming phone
manager for the PinePhone where the modem serves as the primary network
uplink. For the regular PC version of Sculpt, the feature is not needed
(hence remains disabled) because USB net can be deployed from a package
as described in:
https://genodians.org/jschlatow/2021-07-21-mobile-network
The patch also renames the "Local" network option to "Disconnected" to
be more intuitive.
By decoupling the network dialog's menu view from the 'Network' class,
we become able to host the network dialog in the same menu view instance
as other dialogs.
This patch allows the sculpt manager hosted in the leitzentrale
subsystem to observe the toggling between the runtime and the
administrative GUI. This enables alternatives to the use of the
gui_fader for switching between both views. In particular, the
upcoming phone_manager toggles the visibility of its own GUI
depending on the leitzentrale state.
In a Sculpt system based on the upcoming phone_manager, the event filter
obtains its static configuration from /config/managed/event_filter.
Without the requirement for changes at runtime, there is no need to
have the phone_manager in the loop after all.
Without this patch however, this file was always initialized with the
template gems/sculpt/event_filter/default, which was presumably used
only at boot time until the sculpt manager has produced the first
generated event-filter configuration.
This patch applies the choice of optional configs - i.e., a custom
event_filter config - to both the config/ and the initial content of
config/managed/. So in cases where the /config/managed/event_filter
remains entirely static, the latter properly reflects the choosen
variant.
By using the new functions provided by the base API, this patch removes
the dependency of several components from include/decorator/xml_utils.h.
Issue #4584
This patch allows the leitzentrale subsystem to control an audio driver
hosted in the drivers subsystem. An example use case is the toggling of
the speaker during phone calls.
Instead of having a generic "virt_qemu" board use "virt_qemu_<arch>" in
order to have a clean distinction between boards. Current supported
boards are "virt_qemu_arm_v7a", "virt_qemu_arm_v8a", and
"virt_qemu_riscv".

The box layout evenly distributes the child widgets according to the
number of children. This is not desired in the special case where a
child widget has a size of zero. The patch changes the layout algorithm
such that zero-sized widgets are not taken into account for distributing
residual space.
This patch replaces the former implicit "phonyness" of the rule by an
explicit .PHONY and installs a symlink from the target's build directory
to bin/ as is the usual practice for regular targets.

To not integrate referenced depot packages when building a sculpt image,
just set the environment variable DEPOT= to be empty. This allows to produce
slim images to the price that you have to publish the packages yourself.
In that case the sculpt run-script reminds you, and prints the package
versions.

By declaring the generated menu_view_styles.tar archive as build
artifact, it is automatically picked up whenever menu_view appears as
build ingredient of sculpt.
build: app/menu_view
This patch simplifies the use of the menu_view in scenarios where no
absolute motion events but only touch events occur. Previously, such
scenarios required the creation of artificial absolute motion events
via the event filter.
Issue #4514
This patch fixes rare freezes of menu view instances, which could happen boot
time whenever the leitzentale GUI happens to get initialized before the display
driver finished setting up a reasonable mode. In this case, the resolution-
dependent font size can temporarily get almost zero, tripping up the glyph
renderer.
2560x1440 resolutions require more RAM resources. Additionally, make
sure that the decorator 'init' receives enough CAPs to service the
decorator configuration.
fixes#4485
This patch reduces the response time of supposedly stuck situations like
an unresponsive part_block component. First, it reduces the heartbeat
rate from 1 to 2 seconds to make it consistent with the frequency of
state reports. Second, it allows up to four skipped heartbeats until
regarding the situation as stuck. With those changes, the prolonged
initialization sequence of a USB ZIP drive succeeds with Sculpt.
This patch handles the corner case of switching virtual desktops while
child views are visible. Examples of such child views are tool tips,
pull-down menus, or the graph of the top-view utility. The switch to
another virtual desktop would implicitely turn the child views into
top-level views of the root nitpicker GUI server until switching back
to the original virtual desktop.
The patch implements the expected behavior of hiding all child views
that belong to a disappearing top-level view.
The quota adjustments prevent the leitzentrale's decorator from running
out of RAM, and allow the nitpicker GUI server to preserve buffer
content during resize (reducing flickering artifacts) when using a
screen resolution up to 2560x1440.
This patch adds the trace-logger utility to the default set of packages
along with an optional launcher. With this change, only two steps are
needed to use Genode's tracing mechanism with Sculpt:
- Add 'trace_logger' to the 'launcher:' list of the .sculpt file
- Either manually select the 'trace_logger' from the '+' menu,
or add the following entry to the deploy configuration:
<start name="trace_logger"/>
By default, the trace logger is configured to trace all threads
executed in the runtime subsystem and to print a report every 10
seconds. This default policy can be refined in the launcher's <config>
node. Note that the trace logger does not respond to configuration
changes during runtime. Changes come into effect not before restarting
the component.
Issue #4448
The value of 50% as assigned by commit "sculpt: add basic support for
i.MX8 Quad EVK" leaves too little room for other components of the
runtime subsystem. With the adjustements of commit "sculpt: assign CPU
quotas" the sum exeedcs 100%. Hence this commit tunes down the value to
sensible 10%.
By assigning CPU budgets, base-hw's priorities come into effect.
Even though the chosen values are rather guessed than informed, they
yield a visibly improved responsiveness on the Pinephone.

Switch the code to 0 lengh array instead. The code in
Lru_cache::element_size calls sizeof on this structure. This works in
gcc, but fails when using clang. Even for GCC however the documentation
states:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."
Basically its an implementation quirk that clang does not support. Both
GCC and clang do support zero sized arrays however so using them here
allows both compilers to process this code.

Issue #4405
This patch makes Sculpt's leitzentrale GUI able to respond to touch events. It
formerly assumed that click/clack events are always preceded by hover reports
that identify the clicked-on widgets. For touch events, however, the most
up-to-date hover information referred to the previous click because there is no
motion without touching. So the GUI tended to identify the wrong widgets as
click targets.
The patch solved this problem by testing the freshness of the hover information
at the time of the click. If the hover information is older than the click, the
action is deferred until up-to-date hover information becomes available.

* retrieve Genode::Env from plugin, this way no mesa applications need to

* add 'vfs_gpu' api
* remove when all required functionality is implemented within the plugin.
issue #4380
When a <gpu> node is present in the VFS, the plugin opens a
Gpu::Connection for each open call to the 'gpu' node and installs a
completion signal handler. A read only to the fd returned only comes
back if a completion signal has been received between two read
transctions to the fd.
For now the Gpu::Connections can be retrieved by calling the
'vfs_gpu_connection(unsigned long id)' function. The id can be obtained
using 'stat' on the 'gpu' device and is located in the inode (st_ino)
field of the stat buffer.
issue #4380
This patch equips Sculpt with the ability to customize the system image
in very flexible ways.
All customizable aspects of the image have been relocated from the
former sculpt.run script and the accompanied gems/run/sculpt/ directory
to a new location - the sculpt/ directory - which can exist in any
repository. The directory at repos/gems/sculpt/ serves as reference.
The sculpt directory can host any number of <name>-<board>.sculpt files,
each containing a list of ingredients to be incorporated into the
Sculpt system image. The <name> can be specified to the sculpt.run
script. E.g., the following command refers to the 'default-pc.sculpt'
file:
make run/sculpt KERNEL=nova BOARD=pc SCULPT=default
If no 'SCULPT' argument is supplied, the value 'default' is used.
A .sculpt file refers to a selection of files found at various
subdirectries named after their respective purpose. In particular, There
exists a subdirectory for each file in Sculpt's config fs, like
nitpicker, drivers... The .sculpt file selects the alternative to use
by a simple tag-value notation.
drivers: pc
The supported tags are as follows.
*Optional* selection of /config files. If not specified, those files are
omitted, which prompts Sculpt to manage those configurations
automatically or via the Leitzentrale GUI:
fonts
nic_router
event_filter
wifi
runtime
gpu_drv
Selection of mandatory /config files. If not specified, the respective
'default' alternative will be used.
nitpicker
deploy
fb_drv
clipboard
drivers
numlock_remap
leitzentrale
usb
system
ram_fs
Furthermore, the .sculpt file supports the optional selection of
supplemental content such as a set of launchers.
launches: nano3d system_shell
Another type of content are the set of blessed pubkey/download files
used for installing and verifying software on target.
With the new version, it has become possible to supply a depot with the
the system image. The depot content is assembled according to the 'pkg'
attributes found in launcher files and the selected deploy config.
The resulting depot is incorporated into the system image as 'depot.tar'
archive. It can be supplied to the Sculpt system by mounting it into the
ram fs as done by the 'ram_fs/depot' configuration for the ram fs.
It is possible to add additional boot modules to the system image. There
are two options.
build: <list of targets>
This tag prompts the sculpt.run script to build the specified targets
directly using the Genode build system and add the created artifacts
into the system image as boot modules.
import: <list of depot src or pkg archives>
This tag instructs Sculpt to supply the specifid depot-archive content
as boot modules to the system image. This change eliminates the need for
board-specific pkg/sculpt-<board> archives. The board-specific
specializations can now be placed directly into the respective .sculpt
files by using 'import:'.
To make the use of Sculpt as testbed during development more convenient,
the log output of the drivers, leitzentrale, and runtime subsystems
can be redirected to core using the optional 'LOG=core' argument, e.g.,
make run/sculpt KERNEL=linux BOARD=linux LOG=core
The former pkg/sculpt-installation and pkg/sculpt-installation-pc
archives have been replaced by pkg/sculpt_distribution-pc, which
references the generic pkg/sculpt_distribution archive. Those pkgs are
solely used for publishing / distribution purposes.
Fixes#4369
- Consider 'sdl' as source of input events in the event-filter
configuration as generated by the sculpt manager
- Supply an artificial 'platform_info' ROM as requested by the
sculpt manager to obtain the affinity-space information
- Substitute 'fs_rom' for 'cached_fs_rom' as a workaround for the
lack of support for managed dataspaces on Linux
Fixes#4362
This change keeps the version-controlled 'pubkey' and 'download' files
separate from files generated via depot/create or downloaded via
depot/download. So one can remove the entire depot/ directory without
interfering with git.
Furthermore, depot keys can now be hosted in supplemental repositories
independent from Genode's main repository.
Fixes#4364
