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

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.

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.

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.

This commit adds a new configuration option, `dst_addr` to the

deprecated but kept for compatibility until 'dst_addr' is fully adopted.

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

Commit "menu_view: ignore zero-sized widgets in box layout" introduces
zero-sized child widgets as a special case but defined zero-sized as
zero covered pixels (w*h == 0). However, for layouting, a widget with a
non-zero height and zero width is not zero-sized.
This patch refines the zero-size condition such that only widgets with
both zero width and zero height are considered as zero-sized.
It thereby solves the missing display of empty lines in the text_area
component.
The 'Xml_node::differs_from' method takes the constructor arguments
(addr, size) for a byte-wise comparison whereas 'with_raw_node'
restricts the byte range to the actual XML tags. In cases where
the XML start tag is preceeded by whitespace, both ranges can differ.
Since the 'differs_from' method is meant for comparing actual XML
nodes - not any whitespace around them - whitespace should be ignored
on both operands.

This is a follow-up fix for commit "sculpt: apply Dialog API to diag,
panel, and graph", which happened to render the legacy dialogs (network
and settings) inaccessible.
The patch avoids the use of clack seq numbers for the 'popup_opened'
condition (which happens on click, not clack). It also overrides old
click information on the arrival of a new click, avoiding the evaluation
of stale click sequence numbers in distant_runtime.cc. Furthermore, it
reduces the rate of 'Distant_runtime::_try_handle_click_and_clack'.

got overwritten and the force_* got enforced. With the commit,
the connector mode is considered (if below max_*) and the resulting
framebuffer may be larger then the dimension of force_*.

Per Affinity::Location a system control cap can be requested. The capability
provides an RPC interface to request and set Cpu_state, as provided by the
former Pd::managing_system(Cpu_state) method. Invocation of those system
control capabilities then *can* (see below) be executed on the desired CPU
as described by Affinity::Location.
The system control cap will be invalid for kernels that don't support
system_control/managing_system functionality at all.
The system control cap will be ever by the same, e.g. ignoring the
Affinity::Location parameter, if the used kernel doesn't support or doesn't
require the feature to execute the system control per CPU.
The commit is a preparation step to add guarded and selective x86 MSR
access per CPU.

This patch partially converts the Sculpt manager to the dialog API.

Issue #5008
The so-called 'Distant_runtime' implements GUI dialogs via menu_view
components hosted at a distant init instance as opposed to child

parent of the menu_view instances.

The new API at gems/include/dialog/ aids the creation of simple GUI
applications based on the menu-view widget renderer. Its use is
illustrated by the simple test application at src/test/dialog/

Issue #5008
Each hover change of the character position within a label results in a
new hover report, which needs to be evaluated by the application. For
the common cases where labels are used as button texts or for presenting
passive information, the level of detail is not needed while the
recurring hover reports induce overhead at the application side.
This patch mitigates this overhead by excluding labels from the hover
reporting by default.
For use cases that actually depend of precise hover reporting of labels,
for example an editable text area, the hover reporting can be enabled by
setting the 'hover="yes"' attribute of the label.
The 'Widget::_version' attribute was meant to allow the deliberate
replacement of a widget by a same-named widget by changing the version
while keeping the name, thereby suppressing any geomety animation.
However, the implementation missed to populate the attribute with the
value provided by the dialog ROM, prompting the unconditional
re-creation of the widget whenever a 'version' attribute was specified.
Even though this had the (desired) effect of preventing geometry
animations, it could cause feedback loops between hover reports and
dialog ROMs because the 'hover_changed' condition in 'Menu_view::Main'
would always stay true while a versioned widget is hovered.
To prevent exessive allocations the bounce buffers are allocated
once and afterwards re-used. The DMA buffers are provided by an
range allocator whose backing store increases in 4 MiB chunks.
The range allocator might not merge the ranges as those chunks
are not necessarily allocated continously. Allocations larger
than the static chunk size are therefor treated as error.
Internally libyuv uses malloc & free for short time dynamic memory
allocation during image transformation. The converted images are
such large, that the Libc allocator will create and destroy new Genode
dataspace per image. In time sensitive code paths, the overhead can be
noticeable by the caller of the image transformation.
The patch adds the option to register callbacks in the libyuv library to
implement the image allocation by users of the library. They may implement
caching strategies to avoid the overhead, e.g. as seen with qemu-usb and
the webcam model.
and not before. On Windows guest with more than 1 vCPU, the packets

An intermediate state, to due the late packet, has been used to decide to
close the Capture session too early.
In SDL2, support has been added for multiple windows.
As such, prior to this commit, invoking _sdl_screen.construct
would create a new window each time the original window was
resized.
To avoid this, refactor to only construct the window once, and
upon resize events, reconstruct the SDL_Surface and SDL_Texture
of Sdl_screen to the new window dimensions.

Following the official migration guide of SDL [1], the
fb_sdl framebuffer driver was update from SDL1 to SDL2.
The sdl2 port in world/src/lib/sdl2 is used.
Since SDL1 is in maintenance mode [2], support for other
display servers than X11 will never be implemented. In
particular, support for Wayland is missing from SDL1.
Fortunately, a port of sdl2 is maintained in genode-world.
As SDL2 is actively developed, it will provide support for
modern hardware architectures, and has mature support for
Wayland [3].

Issue #4993
The new API emphasizes control over the vCPU data by granting access
through the Vcpu::with_state() method, which makes sure that the vCPU is
stopped, invokes the supplied function with a reference to the VM state
and resumes the vCPU if the function returns true.
The old Vcpu::run(), Vcpu::pause() and Vcpu::state() methods are removed
in favor of the new API. Execution of the vCPU is now interrupted by
sending a native Genode Signal to its Vcpu_handler, which will run the
VMM's exit handling method. When this method retrieves the vCPU state by
calling Vcpu::with_state(), the outside interruption is detected and on
x86 a recall exit is injected into the state to signal the vCPU
interruption / pause request to the VMM's vCPU handler.

instead via the hardware registers of the FPU. On Genode all components and
so VMMs are built such, that the compiler may generate optimized code by
using the FPU at any time. We had to make sure to save the
FPU state as early as possible before the VMM component touches the FPU,
to avoid corrupting & losing guest FPU state. This caused headache again
and again. To avoid the uncertainty, we remove this feature and explicitly
transfer the FPU state via the UTCB.
