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
consistently name the old drivers with a legacy_ prefix.

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.

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.

Implement GLX and X functionality through Mesa's EGL interface. This
requires multiple OpenGL contexts and in turn GEM context support in
libdrm/iris, as implemented in libdrm and intel_gpu_drv.
Update recipes and machine.vbox6 files accordingly,

To actually receive audio input in a particular VM, it also
needs to be enabled in the vbox file:
<AudioAdapter controller="HDA" driver="OSS" enabled="true"
enabledOut="true" enabledIn="true"/>
Fixes#4377
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,
Slightly related to #4313
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
to notify (poke) the NEM backend (nem.cc).
- ever notify about POKE flag for remote vCPU
- check synchronized for NEM state
- store recheck flag and apply on next switch_to_hw
Issue #4313
Use 'StateChange' event to check for machine's 'PowerOff' state, close
Gui connections and submit exit signal to EP which in turns calls exit.
Fixes#4291
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.
Issue #3767
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.

Revert GNU ld to the old behavior where sections with the same name in multiple
ld scripts are merged. Binutils 2.36.1 creates two sections with the same name.
Fixes#4126
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'.
