This change allows a monitored VBox instance to specify a distinct
(lower) priority to the VM session to ensure that the VMM is always
prioritized higher than the VCPUs. This is important because host
I/O at the VMM should always be able to preempt a busy guest.
Issue #4917
Decreasing the internal buffer size will implicitly limit the number
of blocks provisioned for recording and brings them in line with
the number of blocks used for playback (2).
Note that this patch also sets an upper-bound on the number of
samples in 'Audio_*::PERIOD'.
If all connectors are set to disabled by configuration, the connectors
stayed enabled since the new configuration reveals no preferred or minimal
resolution/mode. Instead, use the last set resolution in order to get to the
disabling code.
The memory barriers where introduced with commit "test-timeout: fix build
errors with -std=gnu++20" presumably in order to prevent GCC optimization from
removing the empty for loops the test is using because using a volatile index
variable was no longer an option.
However, the memory barriers seem to have a negative effect on the measurements
performed with the affected loops. The commit caused the timeout test to fail
at least on imx53_qsb.
This commit fixes the issue by using a simple empty for loop without volatiles
or memory barriers but protected inside a function that is compiled with
optimization disabled.

This commit extends the Lx_kit initialization function by passing in
a signal handler that is used to perform the normally occurring
scheduler execution and is a follow-up change for the decoupling
scheduler execution commit.
Instead of burying the signal handler in the 'Lx_kit::Scheduler'
object it is provided by the main object where the driver is free
to perform any additional step before or after executing the scheduler.

Since the wireless LAN driver is actually a 'Libc::Component' due to
its incorporation of the 'wpa_spplicant' application, we have to
intercept its construction because we have to initialize the Lx_kit
environment before any static ctors are executed. Most Linux initcalls
are implemented as ctors that will be otherwise implicitly executed
before the controll is given to us in 'Libc::Component::construct'.
Issue #4927.
The timer used to read the counter first and then the IRQ status. This
could cause a non-wrapped counter value to be considered a wrapped
counter value, leading to bogus timeout durations.
This commit fixes the bug and documents the used timer mode in the
driver in order to make future debugging of the driver easier.

* add a sensible priority setup into the test script in order to protect

Ref #4923
This patch replaces the exception-based error propagation by the use of
'Attempt' return values, which eliminates side effects of the exception
handling - cxx_heap allocations - from code paths that are used by the
the cxx_heap itself (when growing the cxx_heap).
It thereby fixes the failure of the sub_rm test at the "attach RAM ds to
any position at sub rm - this should fail" step.
Fixes#4953
This patch enhances Sculpt with the ability to detect user inactivity
for driving a screensaver by combining nitpicker's hover and focus
reports with a timer.
Issue #4950
Nitpicker's hover and focus reports contain an 'active' attribute, which
can be inspected for the detection of user activity, e.g., as trigger
for a screensaver or for dynamic clipboard policies.
When using the 'Event' session, the reporting code updated the reports
only on incoming events. This patch adds the periodic reporting as used
when using the old 'Input' session.
Issue #4950
Decoupling the scheduler execution can lead to missed interrupts
because the current implementation only handles one pending
interrupt and requires immediate processing.
This commit introduces a helper object that is used to capture
any occuring interrupts that are then handled consecutively.
Issue #4927.
Prior to this commit, whenever an external event occurred, for example
timer or interrupt, the corresponding I/O signal handler was triggered.
This handler unblocked the task waiting for the event and initiated the
immediate execution of all unblocked tasks. Since these tasks may hit
serialization points, e.g. synchronously waiting for packet stream
operations, that require handling of other I/O signals this leads to
nested execution. This, however, is not supported and mixes application
and I/O level signal handling.
The flagging of the scheduling intent is now decoupled from its
execution by using an application level signal handler that is run in
the context of the components main entrypoint. The I/O signal handler
now triggers the scheduling execution by sending a local signal to
the EP.
Since it might be necessary to execute a pending schedule from the EP
directly the scheduler is extended with the 'execute' member function
that performs the check that the scheduler is called from within the
EP and triggers the execution afterwards.
Issue #4927.
On disconnect of displays, e.g. seen with Type-C connectors, the encoder was
not properly disabled due to a missing drm_client_modeset_commit. In order that
the commit succeed, however a fb must be assigned to the modeset. Missing to
do so leads to an -EINVAL by the drm_client_modeset_commit.
Fixes#4948
Fixes alignment faults that occured in the AES256 implementations while
wrapping or unwrapping keys on imx53_qsb, imx6q_sabrelite, and imx7d_sabre.
The problem was that the unwrap_key/wrap_key functions did reinterpret casts
from unsigned char pointers to uint64_t pointers and then directly used the 64
bit values of referenced by the latter. Most probably this caused the compiler
to optimize operations in the assumption that the pointer is 8-byte aligned
which then created alignment faults.
As a solution, this commit changes the interface of the wrap_key/unwrap_key
functions to take uint64 pointers as arguments instead of unsigned char
pointers and then adapts the function users to ensure that they refer to
appropriately aligned memory regions.
Fixed#4932
The initial memory backend implementation was brought over from DDE
Linux and was geared towards use-cases where a high-performing
allocator is useful. In case of the audio driver this is overkill
and since no other driver that could benefit from such an
implementation was ported in the meantime rather use a simpler
implementation that keeps the overhead down.
Fixes#4946.
Since component.cc is no longer linked to core, we can also remove
entrypoint.cc, which was merely a dependency of component.cc.
Related to issue #4784
This patch replaces the global '_wait_for_exit_sem' object by a local
static variable, which does not rely on the global ctors. It thereby
fixes the fault_detection test after the removal of the global ctors
execution from core ("base: remove component.cc from core").

With these options enabled comparative testing between pc_linux drivers
and bzImages becomes much easier on EFI-only machines. The impact on the
actual Genode drivers is minimal.
This patch removes the use of the Entrypoint::schedule_suspend mechanism
and the call of glibc's exit from the lx_hybrid tests, for two reasons.
First, the interplay of atexit handlers executed by the glibc and
Genode's lx_hybrid library is complicated while bringing no benefits in
practice as lx_hybrid applications are usually servers that don't exit
anyway.
Second, the Entrypoint::schedule_suspend mechanism in not used by any
other component. By removing its use from the lx_hybrid tests, we can
remove this mechanism from the base library.
Issue #4940
By supplying only the parts of the Env that are actually relevant for
initializing the cxx heap, we avoid the need for the 'Env' interface.
The patch also moves the call of 'init_ldso_phdr' to the outside
of the cxx library because it does not belong there.

USB devices that are never associated to client sessions lack
usb_per_dev_data (and a kernel thread). Therefore, the devices should be

This commits enables the R8169 driver and was tested with two
RTL8168h/8111h (10ec:8168 rev 0x15 sub 1462:7a38 / 1d05:109f) and
two equal RTL8125B (10ec:8125 rev 0x5 sub 1458:e000) devices
running Sculpt.
Firmware loading is for now not implemented but specific Linux
commits suggest it could be necessary. However, doing so will be
post-poned until we have gathered more experience with the driver.
Restarting the driver might lead to the following IOMMU error

While this approach still scans "holes" in the bus range, it stops
scanning at the maximum subordinate bus number reachable from the base
PCI bus at the host bridge. Startup under Qemu no longer takes about 12
seconds for scanning 256 buses.
By splitting the 'init_capability_slab()' implementation to a separate
compilation unit 'capability_slab.cc', base-hw no longer needs a
customized version of 'lib/base/platform.cc'.

* Removes all previous structs that represented an on-disc block layout
and were therfore subject to a number of layout restrictions (packed,
padding members, enum representations, etc.).
* Adds a replacement struct without any layout restrictions for each of the
removed structs. The new structs are named similar to the old structs.
* Adds block encoding and decoding utilities for easily converting from the
new structs to on-disc blocks and vice-versa (Block_scanner, Block_generator,
T::decode_to_blk, T::encode_from_blk)
* Adapts all affected places in the library to encode and decode proberly
instead of simply casting pointers.
* Thereby cleans up the hashing utilities to use typed-reference args instead
of void pointers.
* Re-enables run/tresor_tester and test-file_vault_vonfig_report for platforms
rpi, imx53_qsb, imx53_qsb_tz, imx6q_sabrelite, imx7d_sabre.
