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
First, the former implementation has only considered the pure numerical
variant of the -m argument. Yet, qemu also allows specifying the amount
of memory by `-m 1G`, `-m size=1G` and more.
Second, the default amount of memory for BOARD=pc was 512M (800M in case of okl4).
Since the depot_autopilot.run also required at least 768M on all
platforms it seems reasonable to take 800M as a default value for BOARD=pc and
thereby remove the special treatment of okl4.

Issue #4281
This follow-up commit to "sculpt: avoid flickering of leitzentrale"
allows nitpicker to double-buffer pixels during resize operation on a
screen size of 1920x1200.
Warning!
The current version of the file vault is not thought for productive use but
for mere demonstrational purpose! Please refrain from storing sensitive data
with it!
The File Vault component implements a graphical frontend for setting up and
controlling encrypted virtual file systems using the Consistent Block Encrypter
(CBE) for encryption and snapshot management. For more details see
'repos/gems/src/app/file_vault/README'.
Fixes#4032
As the file formerly named 'secured_superblock' actually contains the hash of
the superblock that was secured, it was renamed 'superblock_hash'.
Ref #4032
As the file formerly named 'keyfile' actually contains the encrypted private
key of the Trust Anchor, it was renamed 'encrypted_private_key'.

WARNING: BREAKS CONFIG COMPATIBILITY!
This commit changes the configuration interface of the NIC router in a way that
may break systems that use the component without proper adjustment!
How to adjust:
At each occurrence of the 'dns_server_from' attribute in a NIC router
configuration replace the attribute name with 'dns_config_from'. The attribute
value remains unaltered.
DETAILED DESCRIPTION
The new attribute name 'dns_config_from' reflects that also other aspects of
the DNS configuration of the denominated domain are used by the DHCP server
that holds the attribute. This commit is a preparation for forwarding also the
domain name (DHCP option 15) with the mechanism behind the attribute.

framebuffer driver (driver_manager)
* ajdusted drivers_managed-pc to hand out resources to the GPU driver

issue #4233
Adapts Dir_file_system::open_composite_dirs in a way that it returns "success"
when the leaf node of the path is an empty directory but "lookup failed", as
usual, if one of the other directories on the way to the leaf node is empty.
I couldn't find a technical reason why we used to return "lookup failed" when
only the leaf node was empty.
The commit also adds a test for en empty root directory and empty
sub-directories to the fs_query run script.
Fixes#4198
The fs_query component used to exit with an uncaught exception if a queried
directory didn't exist. Now, fs_query will catch this event and simply skip the
affected query, thereby indicating to the user the inexistence of the
queried directory.
Ref #4032
The default size is on most kernels 512M. On OKL4 we have to use 800M,
because of the statically configured memory ranges in the OKL4 kernel.
By avoiding a specific amount of memory, the default Qemu memory sizes are
used.
Issue #4095
This patch increases the RAM quota of the top-level nitpicker instance
to 12 MiB so that resize operations can be buffered for resolutions up
to 2560x1080. It mutes diagnostic messages of the form "Warning: Gui
(...) not enough RAM to preserve buffer content during resize" and
improves the window-resize experience.
This patch adjusts the matching of the IP address such that the external
IP address is used as opposed the the NAT-local address. It is follow-up
fix of the conversion to the uplink session interface.
Issue #3961
Apparently the skewed motion timings came from the issue fixed by
"timer: restore semantics of periodic timeout 0". With the current
version of the timer, the original motion parameters work just fine.
This patch restores the ability to launch nitpicker within a gui_fb
window. It is a follow-up fix for "nitpicker: make framebuffer and input
optional".
Issue #3812
This patch enables sculpt to utilize the CPU reset mechanism via the
PS/2 controller as well as the information provided via the ACPI FADT
information. Whenever the /config/system file is changed to <system
state="reset"/>, both mechanisms are triggered.
Supporting both mechanisms is useful because the PS/2-based reset does
not work reliably on modern machines. The PS/2-based reset is useful in
the case when the FADT reset information refers to the PS/2 command
port. In this case, the platform driver is unable to access this port
because it is already handed out to the PS/2 driver. In this case, the
PS/2 driver kicks in.
Issue #2726
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.
