Some signal-heavy scenarios (e.g., libc_integration) produced the
following warning that hinted a data race on signal data in the context
object.
Warning: returning signal with num == 0
The cause was the use of Signal_context::local_submit() in the libc
introduced in
424ed1b79a libc: remove Reconstructible / use local_submit in kernel
in combination with a missing context-mutex aquisition resulting in a
data race on Signal_context::_curr_signal.
Issue #3923
The commit "sculpt_manager: relax nic_drv policy label" introduced the use of
the "label_prefix" attribute instead of "label" for the uplink policy in the
NIC router. However, it missed an appropriate adaption of the lookup of that
attribute when the Sculpt manager has to decide which uplink is used in a
manually managed router config. This caused the uplink to disappear whenever a
user created a manually managed router config. This commit fixes the problem.

This prevents errors like the following during parallel builds.
MERGE ld-hw.abi.so
/usr/local/genode/tool/21.05/bin/genode-arm-ld:symbol.map:0: syntax error in VERSION script
Replace usb_kill_urb() by usb_unlink_urb() in the timeout handler for
control URBs, as usb_kill_urb() may block and is not allowed to be
called in IRQ/bottom half contexts.

Count more accurately how much packets are in flied, and whether
new packets can be handled. Moreover, catch potential exceptions
whenever acknowledging a packet, and warn about the lost acknowledgement.

There is at least one client that performs DRM calls from multiple
pthreads, which is not supported for now. We guard the concurrent
access by grabbing a pthread_mutex before each operation.
This commit circumvents faulty behaviour of base-pistachio, if
the PCI config space gets requested megabyte-wise. It occurs that
we get a mapping sequence in between sigma0, core and component,
like the following: 0xe1000000 => 0xbf001000 => 0x10b000,
with the consequence that the component stalls when accessing
the latter one. By requesting I/O memory aligned to the size,
the faulty behaviour vanishes.

This is required for scenarios in which a device appears at a later
point in time. If the ROM is not updated, the device_by_type() method may
operate on an outdated dataspace and never find the device it is waiting for.
Although we do not have the full ACPI information parsed yet, to
announce non-PCI devices derived from the ACPI tables, the device
description of the assumed devices is now integral-part of pci_decode.
Formerly, the information was gained separatedly as boot-module, whereby
we lost synchronization in between ACPI/PCI parsing, BIOS handover, and
PS/2 emulation code already acting.
This recipe combines the dummy_rtc_drv, which consumes a given time,
and provides the "Rtc" service to its clients with the simple NTP client,
which provides the current time to the RTC driver in regular intervals.

During interrupt handling the driver masked and cleared interrupts as
recommended in the spec to prevent spurious or unnecessary interrupts
from occurring.
Due to the way the current implementation operates new Block requests
got submitted while handling completions for already finished ones.
Since interrupts where masked at this point the controller did not
generate interrupts when the newly submitted requests got completed.
As the mask/clear optimization is apparently not strictly needed and
according to the spec undefined when using MSI-X it is removed.
Fixes#4684
200 TSC ticks for max measurement duration can get too small on platforms
with high TSC frequencies (e.g., >3GHz) and low CPU frequencies often
caused by HWP configurations. Therefore, we express the measurement
duration in NS (not ticks) and calculate max duration ticks using the
TSC frequency. This way the max duration becomes independent of the TSC
frequency.

This commit enables users of the VMM to define CPU type and count, RAM size,
kernel and initrd ROM names, GIC version, and Virtio devices to be used.
Derived from the configuration values a flattened device-tree blob (DTB) is
generated and transfered to the VM.

Lack of MSI-X support in DDE Linux causes a timeout when the Intel AX211
tries to call back into the driver while loading the PNVM file while
interrupts are still disabled.
