4c4962b306 nic_router: clean-up session creation with class
Introduces a new class that does the clean-up if some exception is
thrown while creating the session. This reduces redundancy and overall
lines of code.

7c77a98118 cpu_balancer: make test reliable
by just test the migration feature, without relying on load measured on the
CPUs. On Qemu (and depending on other load in the Linux system), the migration
feature gets not triggered in time reliable.

5ca6dd10f8 monitor: forward priority session argument
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.

647631af09 test/timeout: revert use of memory barriers
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.

8463f4910a nitpicker: improve activity reporting
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.

563f55e57b nic_dump.run: relax test procedure
This test was originally a copy of ping.run and therefore unnecessarily
inherited all its complexity for testing ping component behavior. Additionally,
ping.run was more actively maintained and evolved over time whereas
nic_dump.run didn't receive the same care. Now, the test fails on certain
platforms although NIC dump works just fine. Therefore, this commit reduces the
test behavior to what is really necessary for testing nic_dump and by doing so,
also fixes the failing targets.

6a57683e52 New debug monitor
The new monitor component at os/src/monitor is the designated successor
of the gdb_monitor. This initial version, however, implements only the
subset needed to inspect the memory of the monitored component(s).

In contrast to the gdb_monitor, the new component supports the monitoring
of multiple components, leveraging the sandbox API. It can therefore be
used as a drop-in replacement for the init component. Like the gdb_monitor,
the new monitor speaks the GDB protocol over Genode's terminal session.
But the protocol implementation does not re-use any gdbserver code,
sidestepping the complexities of POSIX.

There exist two run scripts illustrating the new component. The
os/run/monitor.run script exercises memory inspection via the 'm' command
by letting a test program monitor itself. The os/run/monitor_gdb.run
script allows for the interactive use of GDB to interact with monitored
components.

f2153f9b2f sandbox: allow for customized PD access
By default, the sandbox uses the Env::pd() as reference PD session of
the sandbox children.

However, to accomodate use cases where the interplay of the reference
PD session and the child's address space needs to be intercepted, this
patch adds a constructor that takes an interface for the controlled
access of PD intrinsics as argument.

9b5944b90c platform_drv: use IOMMU devices
Every session component manages a registry of Io_mmu::Domain objects
that it creates on demand depending on the acquired devices (i.e. the
IOMMU devices referenced by the acquired devices). Via the domain
objects, a session component adds/removes the address ranges of the
allocated DMA buffers. Additionally, domain objects provide an interface
for enabling/disabling pci devices.

Domain objects get destroyed with the corresponding control device.
Moreover, on devices/policy ROM updates, domain objects of control
devices that are not referenced by any acquired device anymore get destroyed.

This allows referencing an arbitrary number of IOMMU devices within a

</device>

The specified name is supposed to refer to an existing device in the
devices ROM. The platform driver automatically acquires known IOMMU
devices whenever they become available so that the device object can be
looked up from the platform-driver-owned devices.

ae0e0c118e nvme_drv: add support for host-memory-buffer
This commit introduces support for the HMB feature and will setup the
buffer during start-up. The host-memory-buffer (HMB) feature is mostly
used on NVMe devices that do not make use of an DRAM cache to store its
translation tables amongst other operational data. Not using HMB can
impair the performance on such devices.

The memory is allocated in 2 MiB chunks of DMA-capable memory and its
total size in bytes is configurable via the 'hmb_size' config attribute.
The driver always checks the minimal and preferred size of the HMB and
issues a warning in case it is not enabled via the configuration.
Moreover, if the configured size is less than the minimal amount
required by the device the HMB is not configured at all and a warning
is issued also. If the configured size is more than the preferred size
it will be capped to that amount.

bdf47785b8 vfs: remove 'file_size' from read/write interfaces
The 'file_size' type denotes the size of files on disk in bytes. On
32-bit architectures it is larger than the size_t, which refers to
in-memory object sizes.

Whereas the use of 'file_size' is appropriate for ftruncate and seek, it
is not a suitable type for the parameters of read/write operations
because those operations refer to in-memory buffers.

This patch replaces the use of 'file_size' by size_t. However, since it
affects all sites where the read/write interface is uses, it takes the
opportunity to replace the C-style (pointer, size) arguments by
'Byte_range_ptr' and 'Const_byte_range_ptr'.

  * Introduces != operator to the public Port class in the net library.

1b1a9ca95c nic_router: fix bad connection states on IP change
When a domain receives a new dynamic router IP address and that domain has
active connection states (TCP/UDP/ICMP) from another domain with NAT applied,
the connection states used to stay active while becoming obsolete. They
become obsolete because their identification and their packet processor
use the old routers IP address due to NAT.

One consequence was that connections became dysfunctional when the server
domain received a new dynamic router IP address. Request packets were still
routed from client to server, but when entering the server, their source IP
address was the outdated router address. Consequently, the server responses
used the outdated address as destination and the router dropped the responses
because it did not know this address anymore.

This commit fixes the problem by letting a domain destroy all its connection
states that were initiated from within other domains whenever it detaches from
its current IP configuration.

Strictly speaking, it is not necessary to destroy all connection states, only
those that the domain applies NAT to. However, the Genode AVL tree is not built
for removing a selection of nodes and trying to do it anyways is complicated.
So, for now, we simply destroy all connection states.

Note that the other way around was handled correctly already. When a domain
detaches from its IP config, all interfaces of that domain destroy all the
connection states they created (towards other domains).

7a7cac57d9 nic_router: futile ip config updates on dhcp renew
If the IP config does not change on updates to the router IP config of a domain
change (a common case on DHCP RENEW), prevent detaching from the old config and
attaching to the new one. Because this would not only create unnecessary CPU
overhead but also force all clients at all interfaces that are listening to
this config (via config attribute 'dns_config_from') to restart their
networking (re-do DHCP).

ff2176a586 vfs,libc: support write fds in select
By adding a 'write_ready' interface following the lines of the existing
'read_ready', VFS plugins become able to propagate the (de-)saturation
of I/O buffers to the VFS user. This information is important when using
a non-blocking file descriptor for writing into a TCP socket. Once the
application observes EAGAIN, it expects a subsequent 'select' call to
return as soon as new I/O buffer space becomes available.

Before this patch, the select call would always return under this
condition, causing an unnecessarily busy write loop.

5ad98f2b7c vfs,libc: introduce Vfs::Env::User interface
The new interface is meant to replace the 'Vfs::Io_response_handler'.
In contrast to the 'Io_response_handler', which had to be called
on a 'Vfs_handle', the new interface does not require any specific
'Vfs_handle'. It is merely meant to prompt the VFS user (like the libc)
to re-attempt stalled I/O operations but it does not provide any
immediate hint, about which of the handles have become ready for
reading/writing.

7d8d4f4532 vfs,libc: deferred wakeup of remote peers
This patch facilitates the batching of I/O operations in the VFS library
by replacing the implicit wakeup of remote peer (via the traditional
packet-stream interface like 'submit_packet') by explicit wakeup
signalling.

The wakeup signalling is triggered not before the VFS user settles down.
E.g., for libc-based applications, this is the case if the libc goes
idle, waiting for external I/O.
In the case of a busy writer to a non-blocking file descriptor or socket
(e.g., lighttpd), the remote peers are woken up once a write operation
yields an out-count of 0.

The deferring of wakeup signals is accommodated by the new 'Remote_io'
mechanism (vfs/remote_io.h) that is designated to be used by all VFS
plugins that interact with asynchronous Genode services for I/O.

4bacba431b nvme_drv: do not mask interrupts
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.

49b4b8597d os/pin_driver: support for time-multiplexed in/out
This patch equips the pin-driver framework with support for the
time-multiplexed operation of a pin as output or input. This is needed
when implementing I2C communication via a bit-banging driver.

To operate pin in both directions, a driver obtains both a pin-state and
a pin-control session for the same pin. The pin-state session can be
used to sense the current pin state. The control session allows the
client to set the pin to high or low (using the 'state' method), or to
set it to high-impedance via the 'yield' method. Once switched to
high-impedance, the pin can be used as input.

c83f307b62 nic_router: consider DHCP client optimization
Some DHCP clients (Debian VM in Sculpt) persistently store the last lease they
obtained and try to directly DHCP REQUEST it on a new startup whithout doing
DHCP DISCOVER beforehand. In case the NIC router doesn't know about the lease
anymore (timeout, new router instance), the router used to just ignore the DHCP
REQUEST. This led to significant delays in the network startup of the client
(delayed retries until give-up and DHCP DISCOVER). With this commit, the router
answers such packets with a DHCP NAK instead, causing the client to directly
switch to DHCP DISCOVER.
