The _device_specific_features() implements part of the Virtio_device
interface. Decorate it with override keyword to make this clear and
also satisfy clang which produces warning regarding this.
Issue #3984
Clang 11 produces the following warning when building port_allocator.cc:
port_allocator.cc:27:21: error: result of comparison of constant 65536 with
expression of type 'const Genode::uint16_t' (aka 'const unsigned short') is
always true [-Werror,-Wtautological-constant-out-of-range-compare]
(port.value < (unsigned)(Port_allocator::FIRST +
Basically the code compares Port::value (uint16_t) against a constant
65536 which is larger than UINT16_MAX (65535). This comparison will always
be true.
Issue #3984
According to clang there are two symbols which File_system can refer to:
1. namespace File_system from ram_fs/chunk.h.
2. Vfs::File_system class from vfs/file_system.h.
Make it clear we refer to the File_system namespace in this case.
Issue #3984
Clang 12 complains that Interface can both refer to Genode::Interface
and Net::Interface in this case. Explicitly state the code refers to
the latter.
Issue #3984
This trace policy can be used as a fault-injection mechanism.
Once installed, the next time the traced thread passes a trace point
(e.g., RPC call, RPC request, ...), the policy produces a divide-by-zero
exception.
* Remove SPEC declarations from mk/spec
* Remove all board-specific REQUIRE declaratiions left
* Replace [have_spec <board>] run-script declarations with have_board where necessary
* Remove addition of BOARD variable to SPECS in toplevel Makefile
* Move board-specific directories in base-hw out of specs
The new helper function returns a boolean value analoque to 'have_spec' if the
BOARD variable corresponds to the given value. It shall replace [have_spec <board>]
declarations in run-scripts.
Ref #3971
In order to perform a smooth transition from NIC drivers that act only as NIC
session clients to NIC drivers that act only as Uplink session clients, this
commit introduces an intermediate state in which all NIC drivers support both
modes. That said, a NIC drivers mode is now statically determined through a new
optional 'mode' attribute in the drivers <config> tag that can be set to either
'nic_server' (default value) or 'uplink_client'. Reconfiguring this attribute
at a driver doesn't have any effects. Whithout this attribute being set, all
NIC drivers will behave the same as they did before the commit. When set to
'uplink_client', however, instead of providing a Nic service, they request
an Uplink session whenever their network interface becomes "UP" and close the
session whenever their network interface becomes "DOWN".
Ref #3961
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.
Ref #3961
Adds new Uplink session interface, the corresponding client side (Client,
Connection), and the corresponding API archives. An Uplink session is almost
the same as a NIC session with the difference that the roles of the end points
are swapped. An Uplink client is the one that provides a network interface
(for instance, a NIC driver) whereas an Uplink server is the one that uses
that network interface (for instance, a networking stack).
Therefore, in contrast to the NIC session, MAC address and link state come from
the Uplink client. The link state is reflected through the lifetime of an
Uplink session: The client requests the session only when the link state is
"UP" and closes it whenever the link state becomes "DOWN" again. The MAC
address is transmitted from the Uplink client to the Uplink server as an
argument of the session request.

* Adds documentation how to prepare and finalize a Linux for running the
scenario ontop of it
* Adds consideration of env variable 'ON_LINUX_WITH_DST_IP' that, if set,
adapts the run script to running on Linux with the given ping destination IP

using Register_set && Register. It is derived from Genode::Mmio, however uses
as backend the Config_access implementation which is still used widely in
the platform driver.

Replace explicit usage of bus, device, function arguments to methods or
variables all over the code by a single data type. It eases the reading of and
shorten the code.
Issue #3963
When holding at least one key or button, the hovering should never
change. In the previous version, this invariant was not enforced,
but the symptoms for eventual inconsistencies were masked by two
checkes: one when generating the hover report, and one when submitting
the leave event. This patch enforces the invariant by suppressing any
change of 'User_state::_hovered' while in dragged state.
Fixes#3973
During position scaling use the location width/height which is the permitted
dimension within the child space, instead of using the whole possible
child space. (Fixup for "init: scale affinity location" Issue #1412)
Thanks to the report by Peter.
* Introduce 'use_arp' configuration flag at the NIC router in order to disable
requesting IP-to-MAC address resolutions via ARP for domains.
* Add automated run/nic_router_disable_arp test to the autopilot that tests
the effect of the new flag
* Document the new flag and the new test in the NIC router README
Fixes#3935
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

- Vendor devices add addtional data to the config descriptor, read and
added to the usb session
- allow '0' configuration within the usb session
issue #3822
* The NIC router now considers, memorizes, and, if configured, reports
multiple DHCP option 6 entries from DHCP replies that it received as DHCP
client
* A DHCP server at the NIC router can now be configured statically with
multiple DNS server addresses to propagate
* The 'dns_server_from' attribute of the DHCP server of the NIC router now
supports the forwarding of multiple DNS server addresses
* The automated run/nic_router_dhcp test tests all the above mentioned new
functionality and reconfiguring it at runtime. The test was added to the
autopilot.
* All run scripts were adapted to fit the new NIC router configuration
interface
Fixes#3952
When reconfiguring the NIC router modifies the information that DHCP clients
received through a DHCP server of the NIC router, the link state of the
correspodning interface has to do a "down-up" sequence. This provides a signal
to the DHCP clients to redo DHCP, receive the new information and update
accordingly.
Fixes#3931
* Introduce CPU quota for driver subsytem (needed by sd_card_drv)
* Introduce CPU quota for runtime subsytem and nic_drv (needed by fec_nic_drv)
* Increase CAP quota for inspect terminal slightly
* Add sculpt packages for imx8q_evk
Fix#3958
Updating the config and using its settings instead of only reporting
the new session allows to apply stored channel settings immediately.
In case of Sculpt this is useful when an existing launcher already
contains a valid config that sets the volume levels appropiately or
the 'recall_fs' is used.
Fixes#3930.
