e18c02991e lx_kit: use central signal handler for scheduling
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.

dd1b8a106f drivers/wifi: perform multi-staged construction
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'.

caac994da8 lx_kit: decouple schedule execution
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.

1f1fafb0cf intel_fb: disable encoders of disconnected ports
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.

afaabb3121 pc_nic_drv: add R8169 driver
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:

ea0a692879 wifi: get firmware from tar archive
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.

detailed information on how to configure the driver.

d5710d9de3 Move 'wifi' driver to dde_linux repository
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.

The SDIO connected wireless device on the PinePhone is not available

50541c68ec lx_emul: shadow cpu_relax to update jiffies
There are rare use-cases where cpu_relax is used inside a busy loop
(i2c bus functions), which only will break when the jiffies counter
reaches a specific value.
Because of the cooperative scheduling done in lx_emul, no timer
interrupt will break such a loop. As a workaround, we check for
necessary jiffies updates inside cpu_relax if interrupts are enabled.

578a8c9918 wifi/pc: add rtlwifi driver
Due to lacking hardware access the driver was test with one RTL8188EE
based device, namely [10ec:8179] (rev 01), only. As the access to the
PCI config space is restricted the driver loads the non power-saving
FW and the driver port is therefor only tested with that. The
accesses are documented should we choose to support them one way or
another later on.

The 'wifi.run' run script as well as Sculpt served as testing ground
where the driver worked fine so far.

Fixes #4714.

d33139c40a enable ccache for reference Linux kernel
Genode build system allows to easily enable 'ccache' for builds. This
change allows to enable using 'ccache' also for build of reference
Linux kernel used during porting device drivers.

To enable 'ccache' it is enough to pass value of 'CC' variable when
executing Linux build but this build by default depends on time when it
is built which causes 'ccache' misses. To solve this issue additional
flags are passed to make build independent from time, current user and
host on which build is performed.

5f0ba7d722 intel_fb: handle rapid config change gracefully
In case of very rapid config ROM change (<300ms), the linux driver may still
be in progress of applying the previous change (e.g. switching connector on/off).

During this progress all tasks may become not runnable (waiting for IRQ/timeouts
until hardware state settles), the newest config ROM change/signal gets
dispatched, which lead to continuing the previous change request, but not
to re-starting/re-applying the new config change. To avoid this situation,
explicitly track whether a previous config change was finished and track if an
interim config change request came in. If so, re-start the lx_user
task with the newest config change.

10aa5ebf03 pci_decode: report devices from ACPI info
Although we do not have the full ACPI information parsed yet, to
announce non-PCI devices derived from the ACPI tables, the device
description of the assumed devices is now integral-part of pci_decode.
Formerly, the information was gained separatedly as boot-module, whereby
we lost synchronization in between ACPI/PCI parsing, BIOS handover, and
PS/2 emulation code already acting.

bcea2a958e wifi/pc: implement firmware requests without warning
Until now, requesting optional blobs such as 'iwl-debug-yoyo.bin' has
just failed silently. To support desired blobs such as PNVM firmware,
implement the loading of optional firmware while preserving the nowarn
characteristics of the function.
