The issue came apparent with Windows Guests and USB passthrough of
smart-card readers. If the VM is powered off, PDMR3Term cleans up all
devices incl. (first) acpi and (later) devxhci. The latter used a
dangling reference to ACPI structs in a indirect call to
apicIsLogicalDest() from xhciR3Destruct().

The fix removes our Qemu library reset from xhciR3Destruct() and
registers xhciR3Reset() as PowerOff hook.
Thanks to Raphael for the thorough investigation.
This patch declares that the pseudo target virtualbox6/services/ does

To make room for the re-newed usb_host_drv basing on Linux 5.14 and
the re-newed lx_kit/lx_emul we have to move the depot recipe and

This patch enhances the PD-session interface with the support needed for
user-level device drivers performing DMA. Both RPC functions are
intended for the direct use by the platform driver only. If invoked for
PDs that lack the managing-system role, the operations have no effect.
The 'dma_addr()' RPC function allows the platform driver to request the
DMA address of a given RAM dataspace. It is meant to replace the
'Dataspace::phys_addr' RPC function.
The 'attach_dma' RPC function adds the given dataspace to the device
PD's I/O page table. It replaces the former heuristics of marking DMA
buffers as uncached RAM on x86.
With this patch, the UNCACHED attribute of RAM dataspaces is no longer
used to distinguish DMA buffers from regular RAM dataspaces.
Issue #2243
This patch replaces the direct use of a file-system session via the
'file_system/util.h' helpers by the VFS using the os/vfs.h API. This
makes the component more flexible while removing the dependence from
read and write utilities of file_system/util.h, which happen to rely on
the (now removed) blocking packet-stream semantics.

To actually receive audio input in a particular VM, it also

This change keeps the version-controlled 'pubkey' and 'download' files
separate from files generated via depot/create or downloaded via
depot/download. So one can remove the entire depot/ directory without
interfering with git.
Furthermore, depot keys can now be hosted in supplemental repositories
independent from Genode's main repository.
Fixes#4364
This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.
To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.
Issue #4324
The former use of Pthread conditionals did not cover the corner case of
early wakeups just before halting the CPU. These wakeups were simply
lost which resulted in sporadic halts of about 500 ms (the maximum timeout
of all halts in VirtualBox). RTSEMEVENTMULTI preserves early wakeups
and effectively prevents the CPU from halting.
Additionally, we now wakeup the target CPU on VMMR0_DO_GVMM_SCHED_POLL
and, thus, mimic the behavior of the original implementation slightly
better,

Explicitly, adapt to current framebuffer/window size after
initialization finished. This ensures the use of the correct framebuffer
dimensions in scenarios without a window manager.
Thanks to Raphael for the patch.
This patch replaces the 'Ram_allocator::alloc' RPC function by a
'try_alloc' function, which reflects errors as 'Attempt' return value
instead of an exception.

The commit avoids the race between checking for the NEM state and the decision

- check synchronized for NEM state
- store recheck flag and apply on next switch_to_hw

The new 'Env::try_session' method mirrors the existing 'Env::session'
without implicitly handling exceptions of the types 'Out_of_ram',
'Out_of_caps', 'Insufficient_ram_quota', and 'Insufficient_cap_quota'.
It enables runtime environments like init to reflect those exceptions to
their children instead of paying the costs of implicit session-quota
upgrades out of the own pocket.
By changing the 'Parent_service' to use 'try_session', this patch fixes
a resource-exhaustion problem of init in Sculpt OS that occurred when
the GPU multiplexer created a large batch of IO_MEM sessions, with each
session requiring a second attempt with the session quota upgraded by
4 KiB.

There are some subtle incompatibilities in VirtualBox 6 with settings we
used in version 5. Therefore, the vbox6 package uses machine.vbox6 as
configuration file. An example configuration is provided by the
raw/vbox6 package.
Issue #4281
The service is loaded dynamically VBoxSharedClipboard.so at runtime. The
VFS configuration mounts the shared object at /VBoxSharedClipboard.so as
the file is checked by contrib code before loading. An init
configuration in pkg/vbox6/runtime illustrates this and how to re-label
the VBoxSharedClipboard.so ROM to its real name
virtualbox6-sharedclipboard.lib.so.
During Windows 10 boot with sequential block requests, the AHCI request
worker finished earlier than the EMT thread signals hEvtProcess and
begins waiting for hEvtProcessAck indefinitely. The timeouts helps to
survive this short phase.
A better solution would use conditional variables, which are not
provided in VirtualBox's runtime.
WARNING: BREAKS CONFIG COMPATIBILITY!
This commit changes the configuration interface of the NIC router in a way that
may break systems that use the component without proper adjustment!
How to adjust:
At each occurrence of the 'dns_server_from' attribute in a NIC router
configuration replace the attribute name with 'dns_config_from'. The attribute
value remains unaltered.
DETAILED DESCRIPTION
The new attribute name 'dns_config_from' reflects that also other aspects of
the DNS configuration of the denominated domain are used by the DHCP server
that holds the attribute. This commit is a preparation for forwarding also the
domain name (DHCP option 15) with the mechanism behind the attribute.

In ROM mode the global CapsLock state is controlled by the capslock ROM
by virtual KEY_CAPSLOCK events.
Guests are easily confused by spurious KEY_CAPSLOCK input events in
caps="rom" mode. These spurious events may reach the VMM if KEY_CAPSLOCK
is not pressed as first key in a combination and, therefore, is not
filtered as global key. We filter KEY_CAPSLOCK in ROM mode in the VMM
explicitly, but let it pass in non-ROM mode.
Per default RAW mode is used and CapsLock key events are sent unfiltered
to the guest.
Guests are easily confused by spurious KEY_CAPSLOCK input events in
caps="rom" mode. These spurious events may reach the VMM if KEY_CAPSLOCK

Download gmp, mpc and mpfr with the download script provided by the
gcc source tree and let the gcc build system handle the build of these
libraries with the correct compile options. This fixes build issues on
armhf Linux and removes the need to maintain mpc and mpfr ports in
the Genode tree.
Issue #4094
Unconditionally setting MAKEFLAGS to just 's' is not nice because other
flags cannot be passed through the run script. What the script desires
is to disable the automatically enabled '--print-directory' for sub-make
instances when calling tool/port/current by declaring
'--no-print-directory'.
GDB monitor re-uses internal parts of the sandbox library. It thereby
relies on the internal detail of how local headers are included (using
"" instead of the now usual practice <>). A seemingly unrelated change
"init/sandbox: avoid repetitive state reports" eventually broke the
build of the GDB monitor.
This patch makes the GDB monitor less reliant on the way of how the
sandbox includes headers internally.
It also fixes a few warnings caused by the double definition of
__GENODE__ (adding an missing include guard and making the #define
conditional).

It seems that with the nigthly autopilot the data port (that is choosen by the
client) may stay some time (minutes) allocated after the a test run. This
causes successive tests to fail when trying to reuse the port.
* Use a unique data port for each target platform in the range of 18000-18099.
* Add documentation on how to prepare for running the test on a Linux target.
* Remove Qemu-specific code paths as Qemu isn't supported anymore by the script
since the introduction of the Uplink session (running with a NIC router on
Qemu was never supported and now we always need a NIC router).

The contrib code is updated from 2.4.1 to version 5.2.0 and the used
device-model is changed to QEMU xHCI. Due to this change older guests
OSes, namely Windows 7, that relied on the NEC xHCI device-model will
not work anymore.
The 'Qemu::Controller' interface was extended by an 'info' method, which
returns the vendor and product ID. This allows for removing the
hard-coded values in the VirtualBox glue code.
Issue #4018.
The former implemention assumed that the guest physical memory is
mapped continously. This, however, is not true. Writing larger
files to an USB stick with a Windows 10 guest would therefore lead
to data corruption.
The current implementation uses a bounce buffer to copy the data
to and from the guest physical memory and leaves dealing with the
memory mappings entirely up to the VMM.
Fixes#4017.
* Remove SPEC declarations from mk/spec

Let the NIC router provide an Uplink service besides the Nic service that it
already provided. Requests for an Uplink session towards the NIC router are
assigned to Domains using the same <policy> configuration tags that are used in
order to assign Nic session requests. The MAC addresses of Uplink session
components are _NOT_ considered during the allocation of MAC addresses for NIC
session components at the same Domain. The task of avoiding MAC address clashes
between Uplink session components and Nic session components is therefore left
to the integrator. Apart from that, Uplink session components are treated by
the NIC router like any other interface.

This commit restores the diag feature for selecting diagnostic output of
services provided by core. This feature became unavailable with commit
"base: remove dependency from deprecated APIs", which hard-wired the
diag flag for core services to false.
To control this feature, three possible policies can be expressed in a
routing target of init's configuration:
* Forcing silence by specifying 'diag="no"'
* Enabling diagnostics by specifying 'diag="yes"'
* Forwarding the preference of the client by omitting the 'diag'
attribute

By default, bash brings its own version of 'getenv', named exactly like
the libc function. This becomes a problem in fork/execve scenarios if
the dynamic linker resolves 'getenv' to the bash binary instead of the
libc.

Introduce the managing_system privilege for components like the
platform_driver to allow it to call system management functionality
that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware.
The former RAM resource configuration attribute `constrain_phys`,
which enabled to constrain the region of physical RAM to be used,
gets replaced by the new, broader managing_system configuration
attribute of a `start` node. It gets enforced by the sandbox library.

This patch prevents nitpicker from requesting a framebuffer and input
session by default because the regular use of nitpicker relies on the
capture-session and event-session interfaces by now.
For supporting the nested use of nitpicker via the gui_fb component, it
is still possible to enable the traditional behavior by explicitely
setting the 'request_input' and 'request_framebuffer' config attributes
to "yes".
Issue #3812
This commit applies the transition from the "Input" session to the "Event"
session to the event-filtering mechansim. The functionality of the
input_filter is now provided by the event_filter. The event filter
requests only one "Event" session as destination for the filter result,
which is usually routed to the nitpicker GUI server. It provides an
"Event" service to which any number of event sources can connect.
The configuration of the filter chain remains almost the same. Only the
declaration of the <input> nodes is no longer needed. Instead, the
configuration must specify <policy> nodes, which define the mapping of
"Event" clients (event sources) to the inputs used in the filter chain.
The patch adjusts all uses of the nitpicker GUI server accordingly such
that the event filter reports events to nitpicker's event service
instead of having nitpicker request an "Input" session. This dissolves
the dependency of nitpicker from input drivers.
