The run script uses core, ld.lib.so, and init from depot packages, thus
these cannot be integrated in the image explicitly from the build
directory.
Also, removed special build of report_rom, which is not subject of the
test.

* The problem occured only on OKL4, seL4, and L4/Fiasco
* The test used to continue submitting packets regardless of how many were in
flight
* This commit limits the in-flight packets at the Uplink/Nic connections to 40
each
Ref #4419
This commit changes the touch-click filter to adhere the following
sequence:
touch (physical)
press (artifically generated)
release (artificially generated)
release_touch (physical)
This order is important because nitpicker's focus handling takes
press/release events into account. If the release-touch event appears
before the release event, nitpicker subsumes the release-touch event
to the sequence that started with the press event, instead of handling
it as a free-standing event.
Issue #4332
By assigning CPU budgets, base-hw's priorities come into effect.
Even though the chosen values are rather guessed than informed, they
yield a visibly improved responsiveness on the Pinephone.
When committing a new entry, the buffer wrapped if the last entry fit
perfectly into the buffer. Otherwise, the length field of the next entry
was set to 0 to mark the new head. Yet, if there was still some padding but not
enough to hold the length field of another entry, we ended up with a
headless buffer.
genodelabs/genode#4430
Since the head of the buffer is marked by a zero-length entry, we must
only write the length field if a new head was set. Otherwise, the
consumer might already read the new entry and not find the new head as a stop
condition.
genodelabs/genode#4430
When a device got already acquired by a platform session client, do not
return the same capability again, even if the same platform session
client requested it. Therefore, make doubtful behaviour of client components
visible, and do not have to struggle with Platform::Device instances
instantiated multiple times, which care of the lifetime of the device
capability internally.
Fixgenodelabs/genode#4379
Genode code already expects MMU to be disabled when starting the
kernel. It is enabled eventually in Bootstrap::Platform::enable_mmu,
after setting up translation tables. Unfortunately nothing ensures
this is actually the case. If MMU happens to be enabled when entering
the kernel things go downhill pretty fast after we start messing with
TTBR.
This patch ensures MMU is disabled for EL1, EL2, EL3 dependent on the
exception level of the CPU core, which is entering the kernel.
This should allow base-hw to start correctly on Quartz64 A board.
The `lookup_translation` function got introduced and is used only in the
context to proof whether a cache maintainance function can be executed
safely by the kernel. Unfortunately, it did not checked write permissions,
which can lead to permission faults. This commit restricts the lookup
function to only succeed when the target page is writeable. Consequently,
the lookup function gets renamed to `lookup_rw_translation`.

* Switch from the legacy usb_host driver to the new PC version
in recipes and automated tests
* Update documentation snippets
* Remove outdated, unused usb_rndis run-script
Fixgenodelabs/genode#4416
Do not only report devices, but the current configuration of the driver too,
as long as the `report` node in the configuration states it.
Ref genodelabs/genode#4416
To stay consistent with the configuration of the legacy usb_host_drv
and other components as well, do not report USB devices by default,
but when the following XML node is set within the component's
configuration:
<report devices="yes"/>

The new usb_host driver for PC by default needs more RAM quota in contrast
to the old one. To minor warnings and repeated attempts to open a USB
session from a client, this commit increases the default RAM quota by one
page.
Ref genodelabs/genode#4416
Adds a function to the USB part of the Genode's C API, to enable
usb_host drivers to acknowledge USB request in client's packet buffer
although they are not assigned to an USB device. The requests are
marked with a "no device" error.
This commit fixes a regression originally solved in genodelabs/genode#4149
Ref genodelabs/genode#4416
XML allows attribute values like <node attr="\"/>. The XML parser
wrongly reflects this case as 'Invalid_syntax'. This behavior stems from
the implicit use of the 'end_of_quote' function, which considers the
sequence of '\"' as a quoted '"' rather than the end of a quoted string.
The patch solves this problem by making the 'end_of_quote' part of
the tokenizer's scanner policy.
The patch removes the 'end_of_quote' function from 'util/string.h'
because it is not universal, and to avoid the ambiguity with
'SCANNER_POLICY::end_of_quote'.
Fixes#4431
When a PD owns the right to ask for a RAM dataspace's `dma_addr` it is
concurrently constrained to use allocations of a specific physical RAM area.
This commit further limits this area by removing RAM page frame zero.
Otherwise the return value of `dma_addr` for such a dataspace would be
erroneously interpreted as a fault, because zero is currently the error
return value of `dma_addr`.

This is a follow-up fix for "mk/ld.mk: trigger kernel-dependent
ld.lib.so build", which alleviates the need to specify the KERNEL at the
build-system command line. Thanks to Piotr Tworek for reporting.
Issue #4320
This patch cuts the superfluous dependency of abi.so files from the
library dependencies of the corresponding lib.so file. ABIs depend
only on symbol files.
Prior this patch, the second step of the following sequence would
wrongly re-build the abi.so file.
arm_v6$ make init
arm_v6$ make init KERNEL=hw
As the KERNEL argument does not affect the ABI, the abi.so should
better not be created twice.

The Single_file_system now forwards the
`File_io_service::notify_read_ready` method to the

Do not set '_mode' per default to MANANGED. Check if a manual config ROM
is present during construction and set '_mode' to MANUAL in case it is.
issue #4369
This patch works around 'tar' erroring out when faced with an empty list
of files:
tar: Cowardly refusing to create an empty archive
This can happen when using sculpt.run for a scenario with only a runtime
but no deploy or launcher configuration.
Issue #4369
'generate(Xml_node node)', as used by the Sculpt manager, calls this
function instead of the lambda version. The 'report' function of the
'Genode::Reporter' does not throw an exception in case there is not
enough backing storage for the 'generate' request. Therefore, we have to
check this condition in a loop and call '_increase_report_buffer' in
case size limits are reached.
Patch by Norman Feske.
issue #4369
Genode linker does not support .gnu.hash tables so they will never be
used. Tell the linker not to bother producing them. This should reduce
the size of Genode ELF files a tiny bit without loosing anything
important in the process.
Fixes#4423
According to ARM Cortex-A55 Core Technical Reference Manual r1p0 the
lowest 8 bits (Aff0) of MPIDR register represent thread IDs within a
multi-threaded core. The actual core identification bits are in Aff1.
This layout can be identified by checking the MT bit of MPIDR register.
Basically, if MT=1 core id is in Aff1, if MT=0 core id is in Aff0.
Without this change Genode will identify all CPU cores on A55 as primary
(0) core.
Its worth to mention that Cortex-A55 by itself is not a multi-threaded
CPU. Aff0 values are always expected to be 0 for pure A55 cores. A55
cores can however be paired with cores that are multi-threaded. To
support such big.LITTLE CPUs in Genode we'd probably need to add a
different mechanism for mapping MPIDR values to logical, contignous
core IDs which Genode expects.
