This patch simplifies the 'Deploy::update_managed_deploy_config'
interface by keeping an internal copy of the currently used deploy
template inside the 'Deploy' class. The template is updated whenever
the config/deploy file is modified.
This change weakens the coupling between the '_manual_deploy_rom' and
the '_deploy' subsystem, easing the upcoming implementation of the
switching between presets.
When writing the GPT header, the tool always wrote the GPT entries
belonging to the primary header to LBA following the header. Normally
this is LBA 2 as the header is located in LBA 1. The GPT allows for
up to 128 entries that all in all cover 16 KiB of storage space.
However, on some systems, e.g. ARM-based machines, the bootloader can
be stored in this region. For this reason the GPT entries may be moved
to a different LBA.
This commit changes the tool to adhere to then given GPE LBA in header
when writing out the modified GPT data.

The old 'Io_response_handler::io_progress_response' interface has been
replaced by the 'Vfs::Env::User::wakeup_vfs_user' (issue #4697). The
remaining 'read_ready_response' method is now hosted in the
appropriately named 'Read_ready_response_handler'.

This patch keeps driving the internal state machines until no progress
can be made. This required fixing the return values of several execute
functions, which used to report progress while being in complete state.
Along the way, the patch removes default switch cases to ensure that all
states are covered.
Issue #4706
By adding a 'write_ready' interface following the lines of the existing
'read_ready', VFS plugins become able to propagate the (de-)saturation
of I/O buffers to the VFS user. This information is important when using
a non-blocking file descriptor for writing into a TCP socket. Once the
application observes EAGAIN, it expects a subsequent 'select' call to
return as soon as new I/O buffer space becomes available.
Before this patch, the select call would always return under this
condition, causing an unnecessarily busy write loop.
Issue #4697
This patch removes the 'Insufficient_buffer' exception by returning the
WRITE_ERR_WOULD_BLOCK result value instead. It also eliminates the
superfluous WRITE_ERR_AGAIN and WRITE_ERR_INTERRUPT codes.
Issue #4697
This patch fosters the batching of network packets transferred by the
lwIP stack over the NIC connection. It replaces the eager submission of
the packet-stream's data-flow signals by explicit wakeup notifications.
The commit also increases the NIC session's buffer size from 128 to 1024
packets.
Issue #4697
This patch facilitates the batching of I/O operations in the VFS library
by replacing the implicit wakeup of remote peer (via the traditional
packet-stream interface like 'submit_packet') by explicit wakeup
signalling.
The wakeup signalling is triggered not before the VFS user settles down.
E.g., for libc-based applications, this is the case if the libc goes
idle, waiting for external I/O.
In the case of a busy writer to a non-blocking file descriptor or socket
(e.g., lighttpd), the remote peers are woken up once a write operation
yields an out-count of 0.
The deferring of wakeup signals is accommodated by the new 'Remote_io'
mechanism (vfs/remote_io.h) that is designated to be used by all VFS
plugins that interact with asynchronous Genode services for I/O.
Issue #4697
The commit "sculpt_manager: relax nic_drv policy label" introduced the use of
the "label_prefix" attribute instead of "label" for the uplink policy in the
NIC router. However, it missed an appropriate adaption of the lookup of that
attribute when the Sculpt manager has to decide which uplink is used in a
manually managed router config. This caused the uplink to disappear whenever a
user created a manually managed router config. This commit fixes the problem.
Issue #4660Fixes#4695
The platform driver configuration is missing the required 'info'
attribute that allows the 'vesa_fb_drv' to map the proper I/O
memory address of the framebuffer. In addition the driver requires
at least '2' more CAPs, so raise the quota to '110'.
Fixes#4668.
This patch makes the component graph better reusable for the phone
version of Sculpt. In the phone version, the '+' menu does not exist.
So we need to omit the corresponding button. Furthermore, the storage
dialog is presented in a dedicate section of the GUI instead of
presenting it inside the 'storage' graph node. The phone version
also does not offer the inspect view. So we need to omit the
corresponding buttons.
When using the newer genode_c_api uplink library, an uplink connection uses
the device name as label, which enables integrators to use different policies
resp. routes for different devices driven by one driver. The nic_drv policy
of the nic_roouter configuration generated by the sculpt_manager however uses
an empty label like: "nic_drv -> ". This is the way how existent NIC drivers,
like ipxe_nic_drv requested their uplink session. To support both driver
variants this commit relaxes the policy by checking for a prefix only.

This patch reflects both the pci_decode results and the platform
driver's aggregated device information in Sculpt's /report/drivers/ in
the form of pci_devices and devices files respectively.
Until now, the /config/system ROM was not handled by the sculpt manager
but solely managed by the user. Its main purpose was the ability to
reset or power-down the machine by manually modifying the 'state'
attribute. However, down the road, we'd like to enable the sculpt
manager to drive this state, e.g., to implement the multi-staged
loading of drivers, or to drive suspend-resume states.
The support such scenarios, the 'system' state has been moved from
/config/system to /config/managed/system.
This is a follow-up commit for "menu_view: configurable alpha channel

This patch changes the access of pkg-archives files such that the file

By caching directory listings, the performance of depot_query is no
longer impeded by a massive amount of stat calls while searching for ROM
module locations.
Issue #4611
Upon closer inspection of real-world access patterns, it turns out that
the 'Stat_cache' and 'Cached_rom_query' are not as effective as hoped
for because cache hits are rare while querying pkg blueprints.
However, by increasing the initial size of the blueprint reporter from 4
KiB (default) to 64 KiB has a great effect. With the small default
report size, the querying of blueprints is repeated until the buffer
size suffices, incrementing the buffer size by 4 KiB in each iteration.
Issue #4611
The new 'Dictionary' provides an easy way to access objects using
strings as key. The 'String' received the 'operator >' to simplify the
organization of strings in an AVL tree.
The patch removes the former definition of the 'operator >' from the
platform driver because it would be ambigious now.
Fixes#4610
This patch avoids repetitive depot queries at the start of the Sculpt
system.
We don't need to trigger a query unconditionally whenever the
managed/deploy changes because the call of 'handle_deploy' triggers a
query when needed.
We don't need to trigger a query once the prepare step is completed
because the depot_query component is spawned at this point. The initial
blueprint produced by the depot_query component, in turn, triggers the
'handle_deploy' mechanics in the sculpt manager.
The constructor of the Sculpt manager's 'Main' does not need to call
'depot_deploy' because the prepare step - which is a precondition for
the deployment - cannot be completed at this point anyway.
If provided with a config that does not include a `<static>` or
`<common_routes>` node, depot_deploy exits due to a `Nonexistent_sub_node`
exception. Instead, we should output a more useful warning.
Fixesgenodelabs/genode#4600
The `with_sub_node` method is renamed to `with_optional_sub_node` to
better reflect that the non-existence of a sub node with the desired type is
ignored.
At the same time, the new `with_sub_node` now takes a second functor that is
called when no sub node of the desired type exists.

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

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,

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.

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.
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 value of 50% as assigned by commit "sculpt: add basic support for

sensible 10%.
By assigning CPU budgets, base-hw's priorities come into effect.
Even though the chosen values are rather guessed than informed, they

issue #4369
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.

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.

This patch improves the robustness of the CPU-affinity handling.
- The types in base/affinity.h received the accessors
'Location::within(space)' and 'Affinity::valid', which alleviates
the fiddling with coordinates when sanity checking the values,
in init or core.
- The 'Affinity::Location::valid' method got removed because its
meaning was too vague. For sanity checks of affinity configurations,
the new 'within' method is approriate. In cases where only the x,y
values are used for selecting a physical CPU (during thread creation),
the validity check (width*height > 0) was not meaningful anyway.
- The 'Affinity::Location::from_xml' requires a 'Affinity::Space'
as argument because a location always relates to the bounds of
a specific space. This function now implements the selection of
whole rows or columns, which has previously a feature of the
sandbox library only.
- Whenever the sandbox library (init) encounters an invalid affinity
configuration, it prints a warning message as a diagnostic aid.
- A new 'Affinity::unrestricted' function constructs an affinity that
covers the whole affinity space. The named functions clarifies
the meaning over the previous use of the default constructor.
- Core's CPU service denies session requests with an invalid
affinity parameter. Previously, it would fall back to an
unrestricted affinity.

Moved creating ssh loop thread after initialization of wake up server
file descriptors to make sure that they will be properly handled even in
first loop run.
Issue #4095
pthread.0 acquires a write buffer mutex and calls potentially
blocking fs operations. The EP thread handles session requests and tries to
acquire the same write buffer lock. IO progress events for pthread.0 are
handled by the EP thread, which however is blocking on the write buffer mutex.
The commit uses two write buffers, one which is filled by the EP and a second
which is used by pthread.0. The two buffers are swapped protected by a mutex
without invoking blocking fs operations.
Issue #4095
The exec_terminal generates a config report which is used as input ROM for
sandbox/init, which does not support an "<empty>" node.
An empty config node is empty, without an node.

With this patch, the user is able to re-gain access to the inspect view
by toggling the inspect button of a file system unrelated to the failed
USB storage device.
Fixes#4090
The direct execution of application-level code by a watch handler is
troublesome because those handlers are executed at the I/O signal level.
In the concrete case, the watch handler got recursively called because
the handler called _handle_config (application-code), which called the
VFS, which in turn performed a wait_and_dispatch_one_io_signal, which
again invoked the watch handler.
The patch works around the problem by letting the watch notification
trigger the application-level signal for the _config_handler.
Fixes#4091
This patch adds the handling neccessary for clients to upgrade the cap
quota of their GUI session. Until now, the upgrade mechanism supported
only RAM quota.
The limitation became visible once a client - in the particular case the
motif_decorator - attempted the cap upgrade of its GUI session. The cap
quota would arrive at the wm, but the wm would keep it instead of
forwarding the quota to nitpicker. This resulted in an infinite retry
loop at the motif_decorator, ultimatedly depleting all its cap quota.
The window manager infers the overall state from the intercepted input
events for the decorator and all GUI clients. However, each of those
parties have an independent input-event stream. Whereas the order of
events within one GUI session is strict, the order of events between GUI
sessions is arbitrary. The window manager wrongly relied on a global
event ordering to track the pointed-at GUI session.
The patch removes the assumption of a global event order by tracking the
relevant pointer state for each GUI session independently and evaluating
these states when propagating the pointer position to the decorator.
Fixes#4059
The addition of further keyboard layouts would otherwise pollute the
config/ directory too much.
Caution: When updating Sculpt OS, don't reuse your existing
config/event_filter file unmodified! You need to replace the chargen
includes, pointing to the new location, e.g.,
<include rom="en_us.chargen"/>
<include rom="special.chargen"/>
must be changed to
<include rom="keyboard/en_us"/>
<include rom="keyboard/special"/>
Issue #4055
This patch extends the settings dialog with the ability to select the
keyboard layout between the options that are included in the sculpt
image. The manual configuration is of course still possible by editing
the /config/event_filter directly.
If both the fonts configuration and the event-filter configuration are
managed manually, the settings button and window are not displayed.
Fixes#4055
By sorting the reported output, all consumers of the reports become able
to rely on a deterministic order. For example, the file browser of
Sculpt OS, the launcher menu items, and the depot-selection items will
appear in a predictable order.
Fixes#4054
This patch adds session-routing options to connect components to the
capture/event interfaces of the global nitpicker GUI server or the
leitzentrale GUI server. It thereby enables the implementation of screen
capturing components, remote management tools, or virtual keyboards.
Since those services are very powerful, they are subsumed under the
"hardware" category of the component graph as opposed to the GUI
category, which guarantees the separation of clients.
Fixes#4053
This patch adds 4 priority levels to the runtime subsystem. The highest
priority is used for components that are critical for the operation of
Sculpt, in particular the Leitzentrale GUI. All regularly deployed
components are assigned the lowest priority by default.
With priorities available in the runtime subsystem, this patch flattens
the priority levels at the top-level init to only two levels and
overlays the priority bands of the drivers, leitzentrale, and runtime
subsystems into one priority band. This has three benenfits:
- This change prevents the starvation of the Leitzentrale GUI from a
spinning high-priority driver (issue #3997).
- The change will also ease the hosting of latency-critical components
in the runtime subsystem that are prioritized higher than regular
components, the storage stack, and the network stack.
- The Leitzentrale GUI remains always perfectly responsive regardless
of the workloads deployed from packages. In the previous version,
the runtime graph was sometimes stuttering on high system load.
Issue #4045
This patch triggers the immediate removal of part_block once the
discovery of a fresh inserted USB stick has completed. Without the
patch, part_block was retained until the runtime was reconfigured the
next time for other reasons (e.g., toggling an inspect view). Until the
next reconfituration, part_block tended to stand in the way of directly
assigning the USB device to a VM.
