We repeatedly experience issues with XHCI handoff in the USB host driver
at runtime on modern systems. Mostly, these issues manifest as
initialization delays with very high CPU load. Investigations show that
during this time the handoff MMIO write does not return, which hints the
firmware driver enters some spinning loop. I suspect the enabled IOMMU
does not play well with the firmware due to insufficient RMRR
information.
Therefore, we disable USB handoff in Sculpt via the driver manager (as
we do for dedicated devices already in other contexts). Note, UHCI and
EHCI handoff is still done in the platform driver and succeeds on all
our test hardware.

This split allows us to cross-compile all arm_v8a packages needed for
'goa build' by creating pkg/arm_v8a/goa.
The components featured on pkg/goa-linux are solely needed for 'goa
run'. As they contain a number of lx/hybrid components, pkg/goa-linux
must be complied on Linux running on the target architecture.
Fixes a regression with the cbe_init_trust_anchor component that prevented
reacting to a failed unlock attempt in the File Vault. The regression was
caused by new semantics in the vfs that did not allow for using the file
operation result as indicator for whether the unlock attempt failed or
succeeded. The correct and hereby applied approach is to check for the data
read from the file after having written the unlock command. The data reads
either "ok" or "failed".
This patch mitigates potential busy feedback effects when evaluating the
reports produced by 'depot_deploy' in a closed control loop. Reports
are now generated only if the deployment state has changed.
Issue #4818
This patch marks a child as incomplete if one of the ROM modules listed
in its blueprint is missing. This, in turn, triggers the update system
in Sculpt, which then tries to download the missing pieces.
Issue #4818
By managing downloads issued by the deploy subsystem via the
'Download_queue', failed downloads (e.g., due to HTTP error 404) are
properly tracked and don't cause infinite re-attempts.

This patch replaces the former 'nic_drv' and 'nic_drv_dtb' functions
by a more general 'nic_driver_routes' function that can return one or
multiple platform-specific ROM routes for NIC-driver binaries and dtb
files. This allows for supplying customizations for the wifi driver
as well. E.g., on the PinePhone, this hook can be used to handle the
renaming of the 'wifi_drv' to 'a64_wifi_drv'.
Related to issue #4813 and issue genodelabs/genode-allwinner#17.
This commit updates the used firmware images for the iwlwifi device

Fixes#4807.
Unfortunately, the change of "depot: remove empty config from
pkg/nano3d" broke the manual deployment of the nano3d demo because no
<config> is provided in this case.
This patch splits pkg/nano3d into two variants. The regular nano3d pkg
comes with an empty <config/> node as before. The unconfigured_nano3d
pkg does not feature any <config/> node and can thereby be configured
via a ROM route to a dynamic-rom service.
This patch equips the depot_download subsystem with the option to
explicitly skip the signature verification for downloads by specifying
the attribute 'verify="no"' for an <installation> item. This is useful
in scenarios where the lack of integrity of downloaded content does not
pose a risk, e.g., for untrusted applications that are rigidly
sandboxed, or during development.
Note that this option does not entirely discarge the signature checking.
Whenever an download has dependencies that are verifyable - for
which the public key exists in the depot - the dependencies are still
verified. This allows untrusted content to depend of verifyable content
while protecting the integrity the verifyable content.
Issue #4804
This patch adds the 'Verify' argument to all download-related interfaces
in order to control the checking of signatures for downloads. Note that
it does not change the sculpt_manager's existing built-in policy of
always checking signatures.
Issue #4804
This patch moves the interfaces needed for the interactive addition of runtime
components from the 'Popup_dialog' to the 'model/component.h'. So those
interfaces are no longer tied to one specific view implementation.
This free-standing function is meant to gradually replace
'Dialog::match_sub_dialog' interface, which relies on the caching of
the hover state. The new function is more flexible because dialogs do no
longer need to inherit 'Dialog'.
The missing else statements resulted in the addition of a
superfluous <archive> node when installing an <index>, causing
warning messages by the depot-download subsytem.
This patch adds the ability to specify an optional 'as' attribute in a
<rom> module declarion of a runtime file.
<runtime ...>
...
<content>
<rom label="camera-pinephone.dtb" as="dtb"/>
...
</content>
</runtime>
If specified, The depot-deploy tool uses the provided attribute value to
hand out the ROM 'camera-pinephone.dtb' under the label 'dtb' to the
subsystem.
Now, block_devices are reported earliest right after the devices ROM was
parsed and neither AHCI nor NVMe were found. If one or both devices were
found, the report is deferred after all expected reports arrived.
Issue #4791
The 'file_size' type denotes the size of files on disk in bytes. On
32-bit architectures it is larger than the size_t, which refers to
in-memory object sizes.
Whereas the use of 'file_size' is appropriate for ftruncate and seek, it
is not a suitable type for the parameters of read/write operations
because those operations refer to in-memory buffers.
This patch replaces the use of 'file_size' by size_t. However, since it
affects all sites where the read/write interface is uses, it takes the
opportunity to replace the C-style (pointer, size) arguments by
'Byte_range_ptr' and 'Const_byte_range_ptr'.
Issue #4706
The screenshot trigger displays a little red dot at the upper-left
corner of the screen. When touched or clicked-on, it generates an
artificial key-press-release sequence for the print key and disappears
for one second. In this time, a separate screenshot component can handle
the print key by capturing the screen without the red dot appearing in
the saved picture.
The touch-keyboard config accepts the new attributes 'opaque="yes"
and 'background=#112233' to control the dialog background. The

This patch add the support needed for implementing on-target
system-update functionality. The new 'empty' method is required for the
two-step procedure of updating image-index files - removing the old
index, followed by downloading the most current one. It is used to the
detect the completion of the first step.
Issue #4744
This patch reflects more details such as the percentage value for
downloads maintained in the download queue. This makes this information
easier to display at the GUI.
Issue #4744
This patch replaces the generic "In progress..." message by slightly
more concrete information about the type of operation. This is useful to
distinguish the two steps during the expansion of a partition.
This patch enhances the depot_download subsystem with support for
downloading and querying system images.
The installation ROM support the following two now download types:
<image_index path="<user>/image/index"/>
<image path="<user>/image/<name>"/>
Internally, the depot-download subsystem employs the depot-query
component to determine the missing depot content. This component
accepts the following two new queries:
<images user="..."/>
<image_index user="..."/>
If present in the query, depot_query generates reports labeled as
"images" and "image_index" respectively.
The also tracks the completion of each job depending on the depot-
query results, so that the final report contains a result for each
installation item requested. Prior this patch, the inactivity of the
depot-download manager (indicated by an empty state report) was
interpreted as success. But that prevents the proper association of
results and requested installation items.
Issue #4744
The 'scan' query for depot users used to list the names of depot users.
However, the URL and existence of a pubkey is useful to know when
assembling a GUI menu from this list.
Issue #4744
Each time when enlarging the menu view, a new 'Gui_buffer' is
constructed with the new size. At its contruction time, the default
reset background color is in effect, which is evaluated by
'reset_surface' as part of the construction. A custom reset color
takes effect only after the construction. Hence, when the Gui_buffer is
flushed to screen immediately at construction time, the gray default
becomes visible for a short time.
This patch changes the Gui_buffer to accept the reset background color
as construction argument so that it takes immediate effect.

With the new 'presets:' tag, .sculpt files can now refer to deploy
configurations to be integrated in the presets/ subdirectory of the
config file system. Those files can thereby be used as preconfigured
system scenarios. Such a preconfigured scenario can be loaded at
runtime by copying the preset file to config/deploy.
Issue #4731
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

appropriately named 'Read_ready_response_handler'.
Issue #4706
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.

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
Although we do not have the full ACPI information parsed yet, to
announce non-PCI devices derived from the ACPI tables, the device
description of the assumed devices is now integral-part of pci_decode.
Formerly, the information was gained separatedly as boot-module, whereby
we lost synchronization in between ACPI/PCI parsing, BIOS handover, and
PS/2 emulation code already acting.
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
and bg color", which simplifies the code. The '_no_alpha' surface is not
needed because the 'Gui_buffer' provides a 0x0 alpha surface when using
the opaque mode.
This patch changes the access of pkg-archives files such that the file

By caching directory listings, the performance of depot_query is no

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.
This patch splits the former DEPOT=omit option into two variants.
The new 'list' option behaves like the former 'omit' option, skipping
the creation of the tar archive from the depot content referenced by the
deploy configuration but showing a list of depot archives that need to
be published for the deployment.
When specifying 'omit' in th new version, the local depot is not queried
for the packages referenced in the deploy configuration. So the
deployment can refer to packaged hosted only remotely.
Fixes#4605
If provided with a config that does not include a `<static>` or

The `with_sub_node` method is renamed to `with_optional_sub_node` to

called when no sub node of the desired type exists.

The 'file' library makes the gems API depend on the libc, which is not
desireable because most users of the gems API have no direct libc
dependency.
With the changes of issue #4599, the build of each src archive that
depends on the gems API would attempt to build the 'file' library and
thereby demand the libc.
Note that the 'file' library is a relic that should better not be
promoted as part of the gems API. Hence, this patch removes the file
library from the gems API and adds it to the src archives of the few
remaining users.
Issue #4599
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.
