Up to now, when using force_*, all other configured modes of a connector
got overwritten and the force_* got enforced. With the commit,
the connector mode is considered (if below max_*) and the resulting
framebuffer may be larger then the dimension of force_*.
Differences in TAR archive member metadata results in unstable depot
hashes. The following properties have to be fixed: modification time
(incl. time zone), numeric owner and group, permission modes.
Releated to #2842
If all connectors are set to disabled by configuration, the connectors
stayed enabled since the new configuration reveals no preferred or minimal
resolution/mode. Instead, use the last set resolution in order to get to the
disabling code.
This commit extends the Lx_kit initialization function by passing in
a signal handler that is used to perform the normally occurring
scheduler execution and is a follow-up change for the decoupling
scheduler execution commit.
Instead of burying the signal handler in the 'Lx_kit::Scheduler'
object it is provided by the main object where the driver is free
to perform any additional step before or after executing the scheduler.

Since the wireless LAN driver is actually a 'Libc::Component' due to
its incorporation of the 'wpa_spplicant' application, we have to
intercept its construction because we have to initialize the Lx_kit
environment before any static ctors are executed. Most Linux initcalls
are implemented as ctors that will be otherwise implicitly executed
before the controll is given to us in 'Libc::Component::construct'.
Issue #4927.
Prior to this commit, whenever an external event occurred, for example
timer or interrupt, the corresponding I/O signal handler was triggered.
This handler unblocked the task waiting for the event and initiated the
immediate execution of all unblocked tasks. Since these tasks may hit
serialization points, e.g. synchronously waiting for packet stream
operations, that require handling of other I/O signals this leads to
nested execution. This, however, is not supported and mixes application
and I/O level signal handling.
The flagging of the scheduling intent is now decoupled from its
execution by using an application level signal handler that is run in
the context of the components main entrypoint. The I/O signal handler
now triggers the scheduling execution by sending a local signal to
the EP.
Since it might be necessary to execute a pending schedule from the EP
directly the scheduler is extended with the 'execute' member function
that performs the check that the scheduler is called from within the
EP and triggers the execution afterwards.
Issue #4927.
On disconnect of displays, e.g. seen with Type-C connectors, the encoder was
not properly disabled due to a missing drm_client_modeset_commit. In order that
the commit succeed, however a fb must be assigned to the modeset. Missing to
do so leads to an -EINVAL by the drm_client_modeset_commit.
Fixes#4948
With these options enabled comparative testing between pc_linux drivers
and bzImages becomes much easier on EFI-only machines. The impact on the
actual Genode drivers is minimal.
This commits enables the R8169 driver and was tested with two
RTL8168h/8111h (10ec:8168 rev 0x15 sub 1462:7a38 / 1d05:109f) and
two equal RTL8125B (10ec:8125 rev 0x5 sub 1458:e000) devices
running Sculpt.
Firmware loading is for now not implemented but specific Linux
commits suggest it could be necessary. However, doing so will be
post-poned until we have gathered more experience with the driver.
Restarting the driver might lead to the following IOMMU error
messages but the device seems to work anyway:

The implementation was already part of the Zynq's sd_card driver and
since other ARM drivers need it as well, promote it to the common
shadow library.

This commit introduces preliminary support for joining networks secured
via WPA3-personal. So far it was only tested with the one OpenWRT AP
configured for WPA3 (see excerpt below) where it WPA3-only as well as
WPA2/WPA3 mixed worked fine.

Issue #4861.
The supplicant is updated to the current release and is now downloaded
as archive rather than pulled from git. For the time being 'libnl' is
still kept at 3.2.25 as the current 3.7.0 release relies on more Linux
infrastructure that our integration does not provide.
Issue #4861.
This commit changes the firmware handling from requesting each
firmware file as a ROM module that is checked against a list of
known images (including their size) to requesting each file via
the local VFS of the 'wifi_drv'. This allows for using the original
probing mechanism that tries to select a matching firmware version.
The 'repos/dde_linux/src/drivers/wifi/README' file contains more
detailed information on how to configure the driver.
Issue #4861.
This function is called when decrypting RX frames on the CPU on 32 bit
platforms. Since the frames are normally decrypted by the wireless LAN
device and this code path is triggered rather infrequently the byte-wise
implementation should not pose a performance risk.
So far it was only encounter with a 7260 device when running netperf.
Issue #4861.
The bulk of the driver code now lives in the 'dde_linux' repository,
which is available on all platforms, from where it can be referenced by
other repositories.
The 'wifi_drv' binary was delegated to a generic harness that includes
all configuration and management functionality shared by all wireless
device driver components, e.g., the wpa_supplicant. The code of the
device driver emulation environment is located in 'src/lib/wifi'. It
is referenced by the platform-specific driver library that resides in
the corresponding platform repository. The runtime configuration needs
to point the driver to proper driver library.
The platform-specific library is in charge of orchestrating the contrib
source utilized by the driver as well as providing the 'source.list'
and 'dep.list' files. It must include the generic library snippet
'repos/dde_linux/lib/wifi.inc' that deals with managing the emulation
environment code.
The 'repos/dde_linux/src/drivers/wifi/README' file contains more
detailed information on how to deploy the driver.
Issue #4861.
The wifi VFS plugin is solely there to provide a hook for calling
'Lx_kit::initialize()' prior to the static ctors. As the corresponding
symbol can be resolved at run-time there is no need to add the
library as a build-time dependency.
Issue #4813
The device-tree binary is normally required on ARM-based platforms
where as on x86 it is omitted. The platform-specific DTB helper
provides a generic interface for accssing the DTB and needs to be
implemented on each platform.
Issue #4813
The SDIO connected wireless device on the PinePhone is not available
on start-up, which leads to the supplicant failing to initalize
'wlan0'. Normally the supplicant would be used in a way that handling
devices that appear at run-time happens gracefully.
Rather than supporting this behavior we defer the start-up of the
supplicant until the device could be openend successfully for now.
Issue #4813
The MAC address device report should be published once the device is
available. Since this may happen at a later time we have to check the
call.
