In case invalid IRQ numbers are used (255 on x86), the IRQ session creation
request may be denied and the platform driver is killed because of the
uncatched exception, which must be avoided.
Issue #5406
To enable a global key handler to implement motion gestures while a
global key is held, it needs to know the current pointer position at the
time when the global key sequence starts. This is prerequisite for
the window layouter's ability to drag windows by clicking anywhere
within the window while holding a global key.
Issue #5403
This patch enforces the invariant that absolute motion events are
delivered to the hovered client only. If no client is hovered, the event
is discarded.
Otherwise, in a situation where no client is hovered (i.e., due to a
background that does not cover the entire screen) but a focus is
defined, absolute motion events would be delivered to the focused
session. From a client's perspective, when moving the pointer from the
client to emptiness, the client would observe a leave event followed by
absolute motion. This, in turn, confuses the window manager, which
expects that the receiver of an absolute motion event is hovered.

Core uses an instance of 'Pd_session_component' as a representative
for RAM/cap quota accounts used whenever session resources are
donated to core's services. All other facets of 'Pd_sesson_component'
remain unused. Core's instance of 'Pd_session_component' is hosted
at 'Core_env'. Upon its construction, all unused facets of
'Pd_session_component' are initialized by dummy arguments in 'Core_env'.
To overcome the need for dummy arguments, this patch splits the
accounting part of the PD-session interface into a separate
'Pd_account' interface. This gives us the prospect of narrowing
core's current use of 'Pd_session_component' by 'Pd_account',
alleviating dead code and the need for any dummy arguments.
Issue #5408
`Vm_session_component::create_vcpu()` is present across all supported
kernels, yet until now it was not part of the `Vm_session` interface.
Add the method to the `Vm_session` interface. This unifies calls in the
base library and is the basis to remove the need for a common base class
for separate `Vm_session` implementations for SVM and VMX on x86_64.
Issue #5221
Prevent erratic runtime behavior stemming from accidentally passing a
copy to a `Ram_allocator` by making the interface noncopyable.
In consequence, we had to provide an explicit copy constructor for
`Session_env` in server/nic_router, which will be reconsidered in
issue #5405.

Nitpicker used to notify GUI clients about an updated GUI info only when
the total panorama size changed. However, in situations where two
capture clients are swapped, the total size may stay the same whereas
the relation of displays to different parts of the panorama is no longer the
same. Such changes are interesting to some clients like the window layouter,
which needs to update the assignement of screens to displays.
This patch changes nitpicker so that each panorama change is reflected
to GUI clients as a mode-info update.
Issue #5390
The 'size_changed' handling remained without effect when the (last)
display re-appears (e.g., back from screen blank) because
'Capture_root::bounding_box()' delivered the '_fallback_bounding_box'
in the intermediate phase where no display was present. Unfortunately,
'Capture_root::visible()' failed to apply the same logic. This patch
makes 'visible()' consistent with 'bounding_box()'. It has the
welcome effect that nitpicker remembers the pointer position during
the dark phase.
Fixes#5397
When constructing an Usb::Interface and implicitly corresponding
Usb::Endpoint instances only select endpoints relevant for the
given alternate setting.
The libusb has to be changed to delegate the correct alternate
setting to the constructor too.

Foster the Genode books as a single point of reference for Genode's
documentation. E.g., the Getting-Started section of the "Genode
Foundations" book has long obsoleted doc/getting_started.txt. This
patch also remove long orphaned texts like gsoc_2012.txt. The approach
described in the porting guide has now been replaced by the Goa SDK.
The Genode books can be downloaded at the genode.org website. Like
Genode, they are open source. All text is licensed as CC-BY-SA and

The VFS server used to respond to any invalid config by exiting.
By disregarding such configurations instead, this patch makes the VFS
server robust against temporary malconfiguration.
This commit adapts the aperture splitting between the GPU multiplexer
and the display driver where the former now always tries to reserve
32 MiB of aperture space for itself instead of limiting the space
for the display driver. In case the aperture is not large enough
the display driver takes precedence and the GPU service has to make
do with remaining space. In the worst case that renders the GPU
service unusable.
Issue #5377.
This patch fixes focus-follows-mouse problem reported for Sculpt 24.10
when using no (operational) backdrop.
In the absence of a background, nitpicker wrongly delivered absolute
motion events to the most recently hovered client even after leaving the
client's area to a area occupied by no client. These motion events, in
turn, confused the internal consistency of the window managers
enter/leave tracking.
Fixes#5375
Since the panorama depends on the config, nitpicker needs to re-evaluate
the validity of the pointer position after each reconfiguration. If the
pointer position is no longer visible, pick a new visible one.
Issue #5352
This patch handles the case where a mode change happens in-between
session creation and the registration of the mode-signal handler,
which can result in a sporadic loss of response to mode changes.
Noticed while working on issue #5286.
With the change of "gui_session: provide mode info as XML", the
client-side window-close handling became dysfunct because the
window-close state got wrongly interpreted as initial window state, to
the effect that a client's initial-window size policy got applied
instead of closing the window.
This patch makes the inital state of running a windowed application
(when no window size is defined yet) clearly distiguishable from the
state after which the user closed the window. Prior this patch, both
conditions were reflected by an empty <capture/> node in the panorama.
Now, the latter condition is reported as <capture closed="yes"/>, which
alleviates the need to track the life cycle of a window at the client
size.
Issue #5353
If a <domain> is constrained by 'width' or 'height' attributes, clip
the capture rects of the panorama info reported to the client. So the
client observes the constraint as window size.
Issue #5356
Since #5352, the 'screen_size' RPC function returns a rectangle clipped
against the client's bounding box, which unfortunately prevents
screen-capturing applications from determining the actual screen size.
This patch restores the original behavior by clipping the panorama
against client-specific constraints w/o clipping against the client's
buffer size.
Fixes#5365
This patch resets the pixel buffer shared with the capture client
whenever the capture policy is modified and reports the whole buffer as
affected rectangle on the next client call of 'capture_at'. It also
clips the dirty rectangles tracked via 'mark_as_dirty' against the
bounding box of the capture session to avoid the interference of
out-of-view parts of the panorama with a capture client.
Fixes#5368
Sometimes when removing the popup window in Sculpt's Leitzentrale, a few
residual pixels remained. This is caused by the too strict coupling of
drawing and sync handling, effectively executing the fb-sync handler
repeatedly via 'Main::mark_as_damaged' during 'refresh_view' calls.
This tight coupling has two unwelcome effects. First, the sync handling
is executed more often than needed. Second, the sync handling (and fb
flushing) happens at intermediate states when view-stack changes are
applied (like changing a view geometry).
This patch uses a local signal handler to defer the execution of the
sync code until all drawing has finished.
Issue #5347
Issue #5356
When nitpicker is used as nitpicker client as is the case for Sculpt's
Leitzentrale, the time to sleep was tracked wrongly. The fb sync stays
alive only if a refresh operation is actually issued.

Instead of forwarding the whole devices ROM of the platform driver to the

Commit ac42ade introduced a regression that triggered an assertion in
`Dhcp_server::free_ip()` because the DHCP allocation was not properly
removed during a domain update. The underlying issue was that
`with_dhcp_server()` silently landed in the `no_dhcp_server_fn`.
Fixes#5364
Inform all GUI clients of a new version of the mode information whenever
the nitpicker configuration is modified. This is needed because changed
capture policies influence the panorama observable by the GUI clients.
Issue #5352
Fixes the following misbehavior: If a global key is pressed (e.g., Caps
Lock in Sculpt) and the mouse is clicked before release, the global-keys
handler receives the global-key press but no further events of the
sequence, especially *no Caps-Lock release*.
A more reasonable fix may address the "else branch" that deletes the
_input_receiver in case of mouse events without a hovered client too,
which is beyond the narrow scope of this fix.
