The libc's internal calculation of the tv_sec and tv_nsec fields must be
based on the same ms value. Otherwise, tv_sec is not always immediately
incremented whenever tv_nsec wraps. For applications, this inconsistency
can result in observed jumps in time.

This commit brings the etnaviv back end implementation in line
with the one from lima. Since the etnaviv driver itself handles
different contexts implicitly rather explicitly like lima and
iris for the moment only a main-context is used for all operations.
Issue genodelabs/genode-imx#8.
- add PS/2 input drivers
- add GPU client test case - glmark2
- remove display driver before suspend
- route log output via terminal on display to gather information, since in
most cases serial/AMT is not available after ACPI resume

If "verbose" is set to true in the config, AcpiOsPrintf etc. are enabled
to log to a dedicated LOG session using the Format:Console utility.
Issue #5083
Prevent errors if precision and left alignment are part of the string.
String precision is applied to limit access to the configured number of
characters but ignored for other types.

Failed allocations were still denoted with a successful return value
to the caller. This situation was triggered by artificial testing and
has not been observed yet in practice. In case the 'LIMA_GEM_CREATE'
I/O control fails Mesa will dereference invalid pointers anyway.

This patch changes the unlink operation of the ram fs to defer the
destruction of a file until it is no longer referenced by any VFS handle.
When unlinked, the file no longer appears in the directory. But it can
still be opened and accessed.
With this change, a parent process of a Unix-like subsystem becomes able
to pass the content of an unlinked file to a forked child process. This
mechanism is required when using the 'exec' command in Tcl scripts.
Another use case is the 'tmpfile()' function.

By using `mktime()`, which assumes local time, we render the `TZ`
environment variable ineffective. Instead, `timegm()` should be used to
set the real-time clock to UTC.

This option is useful in cases where batching is configured and
failing to fetch a resource should not influence the over-all
result.

This is a follow-up commit to the adaptation of the run scripts to the
consistent use of [build_artifacts] (issue #4860).
The missing build of libm remained undetected until the recent removal
of implicit shared-library builds (issue #5061).
Currently, running ripgrep on Genode emits
"Warning: sysconf(71) not implemented".
Return -1 without setting errno, which is a valid return value according
to getpwnam(3) and silence the warning.
Fixes#5043
FreeBSD libc code uses only a single spinlock instance and, thus there
is no obvious reason why it would need to be implemented as an actual
spinlock. _spinlock() and _spinunlock() functions are implemented with a
static pthread mutex.
Issue #725
This commit adds a new configuration option, `dst_addr` to the
'sntp_client' that accepts either an IP address or a DNS hostname. If a
DNS hostname is provided, the 'sntp_client' will resolve the IP address
before each SNTP request. The 'dst_ip' configuration option is
deprecated but kept for compatibility until 'dst_addr' is fully adopted.
xsd/net_types.xsd: add Net_address type
sntp_dummy_rtc: adjust configuration to use pool.ntp.org

Per Affinity::Location a system control cap can be requested. The capability
provides an RPC interface to request and set Cpu_state, as provided by the
former Pd::managing_system(Cpu_state) method. Invocation of those system
control capabilities then *can* (see below) be executed on the desired CPU
as described by Affinity::Location.
The system control cap will be invalid for kernels that don't support
system_control/managing_system functionality at all.
The system control cap will be ever by the same, e.g. ignoring the
Affinity::Location parameter, if the used kernel doesn't support or doesn't
require the feature to execute the system control per CPU.
The commit is a preparation step to add guarded and selective x86 MSR
access per CPU.
Fixes#5009
Internally libyuv uses malloc & free for short time dynamic memory
allocation during image transformation. The converted images are
such large, that the Libc allocator will create and destroy new Genode
dataspace per image. In time sensitive code paths, the overhead can be
noticeable by the caller of the image transformation.
The patch adds the option to register callbacks in the libyuv library to
implement the image allocation by users of the library. They may implement
caching strategies to avoid the overhead, e.g. as seen with qemu-usb and
the webcam model.
and not before. On Windows guest with more than 1 vCPU, the packets
seem to arrive and/or seem to be handled too late in the Webcam model.
An intermediate state, to due the late packet, has been used to decide to
close the Capture session too early.
