By using the clicked report instead of the hover report, we prevent the
misinterpretation of a regular hover update as an overly delayed hover
report matching a previous click (inside the popup). With this patch, the
popup stays open when the pointer leaves the popup after the click.
Issue #5496
Issue #5485
This patch separates the handling of touch input from pointer input in
the logic of closing the popup dialog. For the detection of a touch
outside the popup dialog, nitpicker's new "touch" report is observed
whereas the detection of a click outside the popup is based on
nitpicker's hover report.
Issue #5496
Issue #5485
This patch decouples nitpicker's handling of touch events from the
handling of pointer devices.
The mouse pointer is no longer following touch position but stays
independent.
The existing "hover" report has now a counterpart "touch" that reports
the most recently touched session, including the initial touch point
and last observed sequence number.

On the unexpected occasion of an invalidation-queue error, the
invalidator gets stuck in an infinite loop. We therefore need to check
for and recover from invalidation-queue errors while waiting.
genodelabs/genode#5523
Each new entry in the invalidation queue must be zeroed before writing
in order to clear data from old entries. Not doing this can cause
invalidation queue errors after the tail pointer wrapped around.

Report 'display_driver_ready' to screensaver depending if <capture> node
is present in Gui::info. The Gui::panorama call does not suffice because
it reports the dimensions of the very last Capture client closed as
fallback.
issue #5496
On some platforms late_ram_regions are initialized to zero which
leads bootstrap to insert zero based/sized ram regions wich later caused
the following warning in core:
! unable to register RAM region base=0x0 size=0x0
! unable to exclude I/O range from RAM: base=0x0 size=0x0
Therefore, omitt adding zero sized regions to the boot info.

In case a play-session client sends data too slow leading to
record-session client depletion after 250ms of inactivity, try to wakeup
depleted clients upon reception of fresh audio data from the
play-session. The _scheduler.consecutive check for triggering a wakeup
doesn't seem to suffice in case of occasionally slow play clients.
(This fixes the osci preset on the PinePhone)

generates it's own numbers

Since "wm/decorator/layouter: window clipping" we need to separate
resize and window-layout ROMs while also adding the <boundary> nodes for
wm/decorator/layouter to function correctly.

This commit removes the aged Block::Driver interface that has already
been superseded by the Block::Request_stream API for some time now.
It is solely used by components whose existence is made redundant,
like 'lx_block', or old drivers, like the SD-Card driver for PL180
and old i.MX53/6 systems or the RPi 1, that have not seen active use
other than in the nightly CI runs.
Fixes#5522.
The 'lx_block' component uses the aged Block::Driver framework
internally and most if not all use-cases where it could be employed
can be addressed by using the 'vfs_block' component instead.
This commit also removes some run-scripts that make use of 'lx_block'
whose components are already excercised otherwise.

Extend the remote cpu call to destroy a thread to be able to
destroy a vcpu as well. Change the vcpu_destroy syscall to
remotely destroy it when the scheduler of the other core has
chosen it at that same point in time.
Fix#5511
Eliminate the assertion as it lets the kernel stall by any smp component
that calls thread's pause syscall, as long as the GENODE_RELEASE flag
isn't set.
Fix#5510
* Remove afiinity artefact from Cpu class
* Scheduler::need_to_schedule => Scheduler::ned_to_update (consistency)
* Don't re-use last scheduler context after new scheduling
decision, might have been deleted (potential use-after-free)
* Move Timer::process_update into timer's interrupt handling routine
* Move execution time of Cpu_context into Scheduler::Context
* Re-order scheduler and idle context initialization (ref before initialized)

When invoking mkimage with '-f auto' the tool uses heuristics to
decide what kind of image to produce. It seems to be related to
the version of mkimage and/or its input data, whether this decision
is done right. Therefore, clearly state the target architecture.
Fix#5519
Solely consider sessions with valid bounding boxes for the decision
to use the fallback bounding box or not. New started capture clients may
require some time between capture session creation and actually capture
screen creation at which the bounding box becomes valid.
Issue #5521
By giving the client a way to specify the origin of the viewport in
addition to the size, we can solve transformed (rotated, flipped)
output to screen buffers where the line length is larger than the
number of visible pixels.
Issue #5518
due to requirements introduced by #5428 to avoid errors alike:
Warning: surface 1376x768 mismatches texture 1366x768
Side effect of this is, that also pixels are captured which are not visible on
screen actually.

The new 'Local_rm' type offers a narrow interface for the interaction
with the component-local address space, managing the lifetime of
attachments by using the 'Allocation' API.
Fixes#5516
The dither matrix is not perfectly random but provides a kind of
pseudo-random pattern that fits the original dithering approach with
global coordinate based indexing. If the matrix is offset by one line
each 16 pixels the pattern becomes visible as alternating light and dark
columns.
Follow-up commit to "gui_fader: precompute dithered 16x16 tile".
Issue #5501
This catches bugs early on. E.g., when leaving an 'Allocation'
unused, it gets immediately deallocated, which is most probably not
intended. For regular 'Attempt' objects, this change encourages
the proper propagation of errors, or at least the logging of unexpected
conditions.
Fixes#5513
This patch converts the memory-allocator interfaces ('Allocator',
'Range_allocator') and their implementations ('Heap', 'Sliced heap',
'Slab', 'Allocator_avl', 'Synced_allocator') to the new 'Allocation'
utility. The new interface resides at base/memory.h whereas the
traditional allocators implement the new interface.
Down the road, the traditional allocators can successively be decoupled
from the traditional 'Allocator' and 'Range_allocator' interfaces.
Issue #5502
Issue #5245
The 'Allocation' template clears the way for precisely differentiating
allocators via (a variety of) C++ types. It turns out that this approach
alleviate the need to consider the differentiation between
mapped/unmapped in ram.h.
With the new approach, a mapped allocator can be built as a template
taking a ram allocator (constrained/unconstrained) and a local
region-map (core local_rm, env local_rm) as ingredients.
Since the differentiation between constrained/unconstrained has its
natural place at ram.h, name the current RAM allocator
'Ram::Constrained_allocator', in anticipation of a future
'Ram::Unconstrained_allocator' with weakened error conditions.
Issue #5502
This patch models the 'Trace::Control_area' as an allocator of slots
using the new 'Allocation' utility and thereby removes the former
exception-based error propagation.
Issue #5245
The new 'raise' function can be used instead of 'throw' to keep the
framework headers void of C++ throw statements, which would otherwise
prevent the compilation of the headers with -fno-exceptions.
In the presence of the C++ runtime, the 'raise' implementation reflects
the supplied error value(s) as C++ exceptions of the appropriate type.
In the (future) optional absence of the C++ runtime, 'raise' remains
unresolved, which then gives us the assurance that the binary contains
no code path leading to 'raise', all error conditions must have been
covered in other ways than 'raise'.
For this reason, 'Genode::raise' is not provided by the base library
but the cxx library (C++ runtime). Once we allow components to opt out
of the cxx library, 'raise' will automatically become unresolved for
those strict components.
