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.

issue #4369
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.

The functionality of the test-block-client, test-block-server, and
test-block-bench components is now covered by the block_tester
application and the vfs_block server.
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.
Fixes#4398
* retrieve Genode::Env from plugin, this way no mesa applications need to
be changed.
* 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
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.
Issue #4300
Similar to other devices allow for selecting a graphics device as
well. This is currently only useful on iMX8-based systems like
iMX8Q-EVK and MNT Reform2 where the driver is explicitly started
from a pkg.
Fixes#4342.
This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.
To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.
Issue #4324
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.

Instead of simply encrypting the private key with AES-256 when storing it to
the 'encrypted_private_key' file, wrap it using the AES-key-wrap algorithm
described in RFC 3394 "Advanced Encryption Standard (AES) Key Wrap Algorithm".
This is more secure and enables us to directly check whether the passphrase
entered by the user was correct or not.

By now, the symmetric keys were only XOR'ed with the private key as placeholder
for a real encryption. Now they are encrypted using AES256 with the TA's
private key as key
Ref #4032.
A private key of 256 bits is generated pseudo-randomly using the jitterentropy
VFS plugin on initialization. The private key is stored in the key file
encrypted via AES256 using the SHA256 hash of the users passphrase. When
unlocking the CBE device, the encrypted private key is read from the key file
and decrypted with the hash of the users passphrase.
