Just add riscv spec files. The riscv versions should use MMIO transport
as ARM versions do. They also should work fine for riscv_qemu machine
from genode-riscv repository.
To not integrate referenced depot packages when building a sculpt image,
just set the environment variable DEPOT= to be empty. This allows to produce
slim images to the price that you have to publish the packages yourself.
In that case the sculpt run-script reminds you, and prints the package
versions.

Make it configurable, whether on a hotplug event the current valid Genode
config for the driver will be re-evaluated. By default it will be re-evaluated.
Issue #4531
On connector unplug the overall resolution of all available active connectors
can shrink and must be considered to potentially re-create the Capture
connection with smaller resolution size. Additionally, update the documentation.
Issue #4531
acpica and the Intel display driver tries to use the Intel Opregion
simultaneously on Genode, which is not supported nor wanted for IO_MEM region as
which it is handled.
Attempts to remove the access to the region was not successful, since some
SSDT table contains ACPI AML code which is executed regularly and read/write
the Opregion.
The patch adds support to read in a copy of the Intel Opregion done by the
acpi_drv component. The copy was sufficient to make the Intel display driver
working to find and lookup the Intel VBT (video bios table) information to
setup all connectors on a Fujitsu U7411 docking station.

Issue #4531
ACPICA needs access to the host bridge 0:0.0 on Intel, which is also
accessed by the Intel display driver. Since for the Intel display driver the
PCI device is specified in the policy explicitly, the PCI device is filtered
out for the ACPICA driver which uses the policy "ALL".
Issue #4532
This commit introduces a hypervisor calling interface. The host kernel can
use it to either switch to a guest VM, or to invalidate the TLB with
regard to a specified VM id.
The VM-specific TLB invalidation is called whenever a VM (Vcpu)
gets destroyed.
Fixgenodelabs/genode#4528
When a PD gets deleted check whether it is active on the current CPU resp. MMU.
If yes, switch to core/kernel's PD to prevent that invalid page-tables or
address-space IDs are still in use. Moreover, whenever we switch to an idle
thread, we switch to kernel/core's PD too. Thereby, we prevent that vanished
PDs are still active on CPUs different from the one, where the core entrypoint
is active, which does the PD deletion.
This whole scheme is only valid under the assumption that core has only one
entrypoint running on one CPU.
Fixgenodelabs/genode#4527
Do not only distinguish core and user threads, but the idle threads too.
Instead of a boolean value, introduce a new thread type.

All access to PCI devices can be handled nowadays via the platform session.
The I/O port access seems also to work not properly on newer UEFI machines.
Fixes#4532
As accommodating the session component object is already taken care of
be the root component implementation, remove the remaining redundant
checks.
Fixes#4521.
Since unblocking the pthread directly may lead to corruption we need
to post-pone it. So we send a signal that should be handled by the EP
after the EP has finished its current line of work.
Fixes#4523.
Instead of allocating the stack via 'kmalloc' point it to the actual
stack used by the task. This addresses issues with the USB
host-controller driver where sometimes hub port enumeration is not
working.
Fixes#4522.
We locally disable 'address-of-packed-member' warnings because GCC complained
about possible alignment issues when returning a reference to a packed member
as naturally aligned pointer (for some reason only on arm_v8a). We know that
the member is aligned to NETDEV_ALIGN via __attribute__ and that the warning
is therefor unnecessary.
Ref #4519
We have to correct the CC_OPT_* variable for these files and used to do so via
phony pre-requisite for the corresponding object files because the correction
had to take place after the variable initialization in
import-lx_emul_common.inc and before the creation of the object files. However,
this caused the objects to always rebuild.
This commit fixes this issue by using Make's feature of target-specific
variables instead. The drawback of this solution is that we can no longer
override CC_OPT_* with a modification of its original value but instead have to
override with a completely new value. This is because otherwise, Make would
either complain about recursive assignment or produce an empty value.
Ref #4519
The strict conversion warnings were disabled during development when the
contrib code was still compiled with the wireguard lib. Now this isn't
necessary anymore as the contrib code is in the wireguard_lx_inc_dirs lib.
Ref #4520
With this commit, the WireGuard component exits with a descriptive uncaught
exception on invalid configurations or when the user attempts to re-configure
attributes that are not re-configurable (private_key, listen_port, interface).
This is particularly important when it comes to the not re-configurable private
key. If the component would just ignore the attempt to override the private
key, the user may come to believe that his old (potentially compromised)
private key is not in use anymore.
The fact that the component now exits instead shouldn't be a problem, as the
user would have to restart the component anyway in order to apply the new
attribute values.
The commit also extends the wg_reconfig run script to test that WireGuard
exits on the attempt to re-configure the private key.

Support removing peers by removing them from the component configuration.
This commit also introduces the wg_reconfig run script that tests adding and
removing single peers.
Ref #4520
I used to set the peer flags to 2 when adding a peer but merely because I
observed that value in my reference Linux. I now found that the flag 1<<1 means
'WGPEER_F_REPLACE_ALLOWEDIPS' and is ignored whenever the peer is new. Anyway,
I keep setting the flag but with the clearer enum name because the wg tool is
doing it as well when adding new peers and we want to stay close to how the
original code interacts.
Ref #4520
Build description files that feature both an actual target and
CUSTOM_TARGET_DEPS happen to re-link the target each time whenever one
of the CUSTOM_TARGET_DEPS is phony, e.g., gems/src/app/menu_view/.
The re-linking of the actual target is of course not desired. By
triggering the creation of CUSTOM_TARGET_DEPS from 'all:' instead of
'$(TARGET)', the specified files do not implicitly become link
dependencies of the target.
Issue #3972
The extra definition introduced by commit:
"lx_emul & arm: define ZERO_PAGE" re-defined the macro included
by a header of the contrib sources. This commit removes the
contrib header and defines thereby missing macros.
Fixes wrong atomic_*(ptr) usage with u32 pointer introduced by
commit "lx_emul: eliminate wrong include pathes". Atomic read or
write is nt needed in our case, we always schedule cooperatively.
Since "Consolidate USB test run-scripts" usb_hid_raw.run depends on
depot archives. Therefore, '--depot-dir' and '--depot-user' must be
passed to the nested run tool to cover cases that customize the depot
(e.g., our nightly CI).
Issue #4511
Introduces the pkg/wireguard archive that depends on the new src/wireguard
archive and deploys one WireGuard component with an empty configuration (can
be configured by the user via a launcher, for instance).
Fixed#4519
Introduce an arch-specific wireguard lib that contains all code from the
former arch-specific target.mk files. This allows us to create a generic
target.mk that merely depends on the library and a dummy.cc file. The latter
ensures that building/linking of the target isn't skipped by the build system.
Ref #4519
The wireguard library's purpose is having a separate INC_DIR setting for the
files that need Linux include paths that would clash with Genode include paths.
Therefore, the name wireguard_lx_inc_dirs is more descriptive. Furthermore,
this allows us to create a new arch-specific wireguard lib in a future commit
in the course of preventing arch-specific target.mk's (a commonly used
approach in Genode).
Ref #4519
The driver wrongfully disabled all APs if it was configured with an
auto-connect list containing multiple APs when one of those was
disabled as a result of using wrong credentials.
This commit changes the way network enable- and disablement are
handled by only operating on the given access-point in question.
It also removes unused code touched by these changes.
Thanks to Peter for bringing this problem to our attention.
Fixes#4517.
