- Avoid dialog changes when clicking on "Add component" while a
routing or resource dialog is unfolded.
The initial implementation of the affinity configuration in
"depot_deploy: support affinity configuration" added the affinity
location attributes to the <start> node of the deploy config. This patch
moves the information into a dedicated <affinity> sub node as done by
the init configuration. So the context of the attributes 'xpos', 'ypos',
'width' and 'height' becomes clear.
It also fixes a usability issue in Sculpt that occurred during testing:
When configuring multiple components with custom affinities, the
resources dialog of later components would wrongly display the state of
earlier components instead of displaying the fresh (default) state. The
resulting configuration would then not match the displayed information.
This is fixed by resetting the dialog state.
As another minor cosmetic change, the patch adds a line break in front
of copied <config> or <heartbeat> nodes.
Issue #3597
With the move of the storage-management dialogs to the graph in Sculpt
version 20.02, the ability to unselect the buttons for destructive
storage operations such as format or expand disappeared. This patch
restores the original behavior.
This patch enables the menu view's new ability to respond to font-size
changes in Sculpt so that the menu view instanced no longer need to be
restarted whenever the screen resolution or font size is changed.
Fixes#3875
This patch allows the use of the VFS watch mechanism for the glyph file
of the TTF VFS plugin so that clients become able to dynamically respond
to font reconfigurations.
Issue #3875
By default, Vim renames a written file to a backup file suffixed with
"~" before writing the current buffer to a new file. Consequently, there
exists an intermediate state when no file exists. Should a client watch
such a file to obtain dynamic configuration info, it observes the empty
state.
Some components have builtin heuristics for such a situation. In
particular, the window layouter falls back to a predefined default
'rules' if no rules are provided as a file. So when interactively
editing window-layouter rules using Vim, it can happen that the manually
maintained rules get overwritten by the default rules.
By setting 'set nowritebackup', we can sidestep this issue by preventing
Vim from producing the bad intermediate state.
Introduce the managing_system privilege for components like the
platform_driver to allow it to call system management functionality
that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware.
The former RAM resource configuration attribute `constrain_phys`,
which enabled to constrain the region of physical RAM to be used,
gets replaced by the new, broader managing_system configuration
attribute of a `start` node. It gets enforced by the sandbox library.

With this patch, sculpt uses init's heartbeat-monitoring mechanism to
detect the failure of part_block instances during storage disovery.
If part_block gets stuck, the device is released and can thereby
be accessed at the whole-device level.
Issue #3861
The check prevents the Ttf_font from violating the bounding box in the
presence of very small scale values. This can happen during the startup
of Sculpt. Before the framebuffer driver is up, Sculpt bases its dynamic
font-size setting on a screen resolution of 1x1.
Issue #3812
The sculpt manager used to defer the initialization of the GUI until
nitpicker's first display report became ready. This way, Sculpt was able
to run headlessly even if the framebuffer driver failed to start up.
Thanks to #3827, nitpicker no longer depends on a working framebuffer
driver. So the sculpt manager is safe to rely on nitpicker in any case,
simplifying the code.

Ref #3848
This patch prevents nitpicker from requesting a framebuffer and input
session by default because the regular use of nitpicker relies on the
capture-session and event-session interfaces by now.
For supporting the nested use of nitpicker via the gui_fb component, it
is still possible to enable the traditional behavior by explicitely
setting the 'request_input' and 'request_framebuffer' config attributes
to "yes".
Issue #3812
This commit applies the transition from the "Input" session to the "Event"
session to the event-filtering mechansim. The functionality of the
input_filter is now provided by the event_filter. The event filter
requests only one "Event" session as destination for the filter result,
which is usually routed to the nitpicker GUI server. It provides an
"Event" service to which any number of event sources can connect.
The configuration of the filter chain remains almost the same. Only the
declaration of the <input> nodes is no longer needed. Instead, the
configuration must specify <policy> nodes, which define the mapping of
"Event" clients (event sources) to the inputs used in the filter chain.
The patch adjusts all uses of the nitpicker GUI server accordingly such
that the event filter reports events to nitpicker's event service
instead of having nitpicker request an "Input" session. This dissolves
the dependency of nitpicker from input drivers.
Issue #3827
This patch replaces the use of the "Framebuffer" session interface by
the new "Capture" session interface in all framebuffer drivers. Thanks
to this change, those drivers have become mere clients of the nitpicker
GUI server now, and are no longer critical for the liveliness of the GUI
server.
The patch touches the following areas:
- The actual driver components. The new versions of all drivers have
been tested on the respective hardware. Generally, the drivers
have become simpler.
- The drivers_interactive packages for various boards. The drivers
subsystem no longer provides a "Framebuffer" service but needs a
valid route to the "Capture" service provided by nitpicker.
- The driver manager of Sculpt OS.
- This patch changes the role of the test-framebuffer component from a
framebuffer client to a capture server so that drivers (capture clients)
can be directly connected to the test component without the nitpicker
server.
- Framebuffer driver no longer support the unbuffered mode.
- The fb_bench.run script is no longer very meaningful because it
interplays solely with nitpicker, not with the driver directly.
- All run scripts for graphical scenarios and the related depot
archives got adapted to the change.
Fixes#3813
Until now, Genode's framebuffer session interface was based on the
RGB565 pixel format. This patch changes the pixel format to 32-bit
XRGB where the X part is ignored. It adapts all graphical applications
and device drivers accordingly.
The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.
Fixes#3784
This commit fixes the 'Out_of_caps' handling. The previous version
mistakenly upgraded the RAM instead the caps as response. The problem
could be triggered by the 'decorator_stress.run' script.
- Since Genode::strncpy is not 100% compatible with the POSIX
strncpy function, better use a distinct name.
- Remove bogus return value from the function, easing the potential
enforcement of mandatory return-value checks later.
Fixes#3752
If a "cat" tool as simple as the removed one is needed, it should be
implemented with Goa, only depend on libc/posix (*not* base), and be
named "simple_cat". Up to today, the misleading naming of the removed
tool, tricked me into believing "test-pipe" tests POSIX pipes, which it
did not!
The 'WHITESPACE' case of the _calc_len method wrongly accessed the
character before checking upper bound of the token. The problem is fixed
by switching the order of both conditions.
Fixes#3756
This patch removes old 'Allocator_guard' utility and replaces its use
with the modern 'Constrained_ram_allocator'.
The adjustment of core in this respect has the side effect of a more
accurate capability accounting in core's CPU, TRACE, and RM services.
In particular, the dataspace capabilities needed for core-internal
allocations via the 'Sliced_heap' are accounted to the client now.
The same goes for nitpicker and nic_dump as other former users of the
allocator guard. Hence, the patch also touches code at the client and
server sides related to these services.
The only remaining user of the 'Allocator_guard' is the Intel GPU
driver. As the adaptation of this component would be too invasive
without testing, this patch leaves this component unchanged by keeping a
copy of the 'allocator_guard.h' locally at the component.
Fixes#3750

This patch replaces the former Noux instance by a sub init that hosts
the combination of VFS + fs_rom + bash. If bash exits, the whole sub
init exits, which implicitly tears down the terminal session used by the
sub init. The latter is expected by the test sequence.
