This option is useful in cases where batching is configured and
failing to fetch a resource should not influence the over-all
result.

In the scope of alloc_dma_buffer(), Out_of_* exceptions might be thrown
at different stages. By adding a Guard object, we make sure to rollback
already created objects accordingly.

As a consequence of the adding IOMMU support to the platform driver,
additional RAM and CAPs are needed for setting up IO page-table
structures.
genodelabs/genode#5002
The platform driver needs additional 2MB of RAM for managing IO page
tables (root table and context tables) that are shared among sessions.
genodelabs/genode#5002
By adding the `irq_type` argument, one can explicitly specify whether to
use LEGACY, MSI or MSI-X interrupts. We formerly used the
`device_phys_config` to implicitly select MSI, however, with the
addition of IOMMU support to the platform driver there is at least one
instance where we need an MSI for a non-PCI device.
Yet, by adding another session argument to the Irq session, we exceed
the character limit for session args. Since not all arguments are
relevant for LEGACY interrupts resp. MSI, we can split the Irq_connection
constructor to handle the two cases separately and omit unneeded
arguments.

DMA buffer allocations are always performed as full pages. However, they
got mapped into the IOMMU domain using the requested size, which may not
be a multiple of the page size. This behaviour was introduced as a regression
by #4761 and is corrected by this commit.

The virtual add_range()-method must not be called from the base-class
constructor since the derived class is not be fully initialized at
this point.

The sculpt manager views only launchers in the + menu that are not present in
the runtime already. However, this check was missing when finding the right
launcher on a click event inside that menu. This could cause the manager to
try deploying an already deployed launcher a again (without any effect)
instead of deploying the launcher that was actually clicked.

This is a follow-up commit to the adaptation of the run scripts to the
consistent use of [build_artifacts] (issue #4860).
The missing build of libm remained undetected until the recent removal
of implicit shared-library builds (issue #5061).
This patch removes the implicit build of all shared libraries a target
depends on. Targets only depend on the respective ABIs instead. This
alleviates the need to locally build complex shared libraries (think of
Qt) when developing applications. Instead, application developers can
use binary depot archives.
The implementation splits the mk/lib.mk file into three files:
- mk/a.mk for building one static library (.lib.a)
- mk/so.mk for building one shared object (.lib.so)
- mk/abi.mk for building one ABI stub (.abi.so)
Furthermore, the commit moves messages and the collection of build
artifacts to var/libdeps, triggers the build of kernel-specific
ld-<kernel>.lib.so, and prunes the lib-dependency tree at ABIs.
Fixes#5061
- finished tx ack queue should be checked before new allocations
- packets which got not sent must be released in packet stream,
otherwise the network packet stream gets filled up and starves after a while
- rRegister for ack avail packets and process them concurrently to EMT-* threads
by nic_ep thread (thanks @Peter for the findings) + add synchronization.
- add sigh_ready_to_submit to network adapter to improve latency by notifying
the network model explicitly in case we had a full packet stream error case
(_retry resp. VERR_TRY_LATER)

This patch mirrors the interface of Sculpt's distant_runtime to the
sandboxed_runtime variant, allowing the configuration of xpos, ypos,
min_width, min_height, opaque, and background color.
Issue #5008
This patch moves the text-editing facility of app/text_area to a
text-area widget as part of the dialog library. This has two benefits.
First, it simplifies app/text_area by using the dialog API. Second, the
editor can now easily be reused by other dialog-API-based applications.
Fixes#5058
The 'Dynamic_array' utility is used by the text_area as internal
representation of text. As a prerequisite step of making the text
editing features generally available as a text-area widget, the
utility must become public.

Several DMA pools of the EHCI/UHCI USB host controller driver declare
that buffers should not cross 4K boundaries. If this property is not met
fatal errors like NMIs may happen during USB operation.

Certain USB devices do not react anymore after an endpoint reset
in the use case of USB devices passed through to a virtual machine.
When investigating the only USB session client that needs the
flush transfers request - namely the Qemu xhci model used in
VirtualBox - there seems to be no need to reset the endpoint in fact.

USB devio splits large transaction into 16 KiB buffers in scatter-gather

of issue #4809 "DDE Linux struct page object aliasing".

Currently, running ripgrep on Genode emits

Return -1 without setting errno, which is a valid return value according

Fixes#5043
This patch replaces the original policy-based 'update_from_xml' by a new
method that takes three functors for creating, destroying, and updating
elements as arguments. XML nodes are associated with their corresponding
internal data models by annotating the element type with the
'type_matches' class function and the 'matches' method.
The patch also improves safety by enforcing that list-model elements can
never be copied.

FreeBSD libc code uses only a single spinlock instance and, thus there
is no obvious reason why it would need to be implemented as an actual
spinlock. _spinlock() and _spinunlock() functions are implemented with a
static pthread mutex.

This commit adds a new configuration option, `dst_addr` to the
'sntp_client' that accepts either an IP address or a DNS hostname. If a
DNS hostname is provided, the 'sntp_client' will resolve the IP address
before each SNTP request. The 'dst_ip' configuration option is
deprecated but kept for compatibility until 'dst_addr' is fully adopted.

`Expandind_pd_session_client::try_alloc` is an overriden virtual method
of `Ram_allocator::try_alloc`. The latter specifies the default Cache
argument as CACHED. The overriden method should either do the same or
not even specify a default argument at all.

On x86, DMA buffers are actually always mapped as cached. We should
therefore actually ask for a cached buffer in order to avoid confusion.

Feed the high-frequent fetchurl reports into a list model to speed up
the subsequent evaluation of the data.
Also limit the rate of state reporting during updates to visible changes
in percent such that most fetchurl reports do not cause any UI activity
(status updating) any longer.
This patch noticeably speeds up the installation of complex packages
(i.e., the morph browser) on the PinePhone.
Issue #5038
The execution of global-static constructors in Genode is optional for
native components or determined in the libc for libc components. By
convention, we avoid static constructors wherever possible but in rare
cases the component can tweak the point when constructors are executed
and initialize an environment beforehand. The wifi_drv applies this
pattern for the uplink initialization, but is a libc component on the
other hand, and, thus, statics in the Genode C API for uplink are
constructed later by the libc. So, the prior initialization is reverted,
i.e. the signal-handler capability becomes invalid.
This addresses a regression exposed by the following commit.

Component names can be larger than widget IDs, which are capped at 20
characters. To uniquely correlate the component depicted in the graph
with clicks, this patch uses a dedicated graph ID for each runtime
component instead.

This patch allows for the interactive assignment of the system-control role
to a new component via the resource dialog. This is useful for integrating
low-level components like the Intel frequency/power monitoring tool.
