This commit de-duplicates the redundant dummy implementations and
to some degree also the 'lx_emul.c' implementations while also
decluttering the various 'dep.list' files.
The code is moved into 'src/lib/pc/lx_emul' where it becomes part
of the 'pc_lx_emul' library.
Fixes#4500.
Instead of each driver providing its own header file use a central
header as the initcall order header should cover _all_ provided
initcalls resulting from the used 'pc_linux' kernel config.
Note that the 'pc_linux' configuration was extended with the
'USB_USBNET' option because the module's initcall is needed for the
Genode C API for USB glue-code and the 'PACKET' option needed by
the wireless lan driver.
The lack of theses options was not noticed as each driver used its
own initcall header so far that stemmed from the initial porting
effort.

* Some fixups for the README
* Make config ROM const when used for the session policies
* Turn Reporter into Expanding_reporter
* Always first register ROM signal handler before parsing it the first time
Outsource parts of the Main object into a common compound object,
common parts of the Makefile description and depot source package.

* Parse PCI specific information from devices ROM
* Enable DMA, I/O memory and I/O port access dependent on BARs in config space
* Introduce device PD for Nova + IOMMU support
* Enable MSIs if available
* Add PCI specific policy rules

Instead of returning an invalid device capability when a device
is (not yet) available, e.g. a PCI device is requested before the
PCI bus got parsed accordingly, we check the device capability
within the Platform::Connection utilities, and register temporarily
an Io_signal_handler to wait for changes of the devices ROM, and
try the device aquisition again. Thereby, simple drivers so not have
to take the burden to do so.
To enable this feature for all drivers, we always have to export a
devices ROM, but limit the information about physical resources
(I/O memory addresses, IRQ numbers, I/O port ranges) to clients with
'info=yes' in their policy description.

By adding a 'report' node to the platform driver's configuration
one can enable either devices or config reports. The devices
report contains all devices and their detailed state, as well as
whether it is already in use or not. The config report contains
one by one the current configuration of the platform driver.
Moreover, this commit adds a README file describing the facilities
of the platform driver.
Fixgenodelabs/genode#4386
If PCI devices happen to miss complete configuration after boot, the
platform driver supports <pci-fixup> nodes for concrete devices
(specified by bus-device-functions tuples). The
<bar> node instructs the platform driver to remap BAR id 0 to address
0x4017002000, which amends the BIOS configuration and is stringently
required for BARs with address 0.
! <pci-fixup bus="0" device="0x15" function="3">
! <bar id="0" address="0x4017002000"/>
! </pci-fixup>
The issue was discovered with Intel LPSS devices in Fujitsu notebooks.
Fixes#4501
This patch changes the libc to query the stack size from the
config attribute <libc> <stack size=""/> </libc> for regular
components, not only cloned processes.
To discharge the generic platform driver from certain PCI bus scanning,
and ACPI + kernel specifics, this commit introduces a new component,
which consumes the acpi drivers report and the platform_info from core
to prepare a devices ROM for the platform driver that contains all
PCI devices and its resources.

USB Attached SCSI devices might expose a bulk-only interface
as fall-back at interface 0 and alternate setting 0. This commit
allows for probing all alternate settings of the active interface
to be able to use such devices.
The configuration was extended so that in case the device interface
is known beforehand the driver can be configured accordingly.
Fixes#4494.
Deploying an overly large meta-pkg in Sculpt leads to an
'Xml_generator::Buffer_exceeded' exception. Using the expanding
reporter solves this problem.
Fixes#4493.
In case we are instructed to reauthenticate and were already
authenticated we ignore the request in the management layer
and let 'wpa_supplicant' deal with that.
Fixes#4488.
The vanilla NOVA kernel solely supports tracking and exporting of execution
times per SC kernel object, but not per thread (EC object). The commit extends
to track execution times per EC in the NOVA kernel, exporting it to Genode's
'core' roottask and populating Genode's Trace::Subject_info structure.
Fixes#4481
Remove handling of ACPI (SCI) interrupt from kernel and thereby let the
handling of the ACPI irq exclusively to an Genode driver. On Genode the ACPICA
library+app handles the ACPI irq, where we can now remove the contrib patches
related to the synchronization between NOVA kernel and ACPICA library.
Fixes#4479
When using the framebuffer driver on this machine the
'cpu_latency_qos_request_active' dummy is triggered. Removing the
trace-and-stop call makes the driver usable.
In addition, 'cpu_latency_qos_remove_request' is changed as well
although it is guarded by 'cpu_latency_qos_request_active'.
Fixes#4489.
This patch fixes rare freezes of menu view instances, which could happen boot
time whenever the leitzentale GUI happens to get initialized before the display
driver finished setting up a reasonable mode. In this case, the resolution-
dependent font size can temporarily get almost zero, tripping up the glyph
renderer.
Since the driver relies on all requests being Nvme::MPS_LOG2 aligned
as advertised in its Block::Info the added check will reject any
misaligned requests (using 'gpt_write' led to an IOMMU write fault).

In rare cases it is necessary to execute Linux contributed code
until certain work is finished, e.g. when in a synchronous RPC call,
a session construction or destruction a result is needed. Therefore,
we introduce a new lx_emul function called lx_emul_execute_kernel_until.

In case multiple devices shared the same memory-mapped I/O page
we have to take the offset into account. This commit fixes the
'pc_usb_host_drv' on the Thinkpad X201 where the two EHCI host
controller share the some I/O memory page.
Fixes#4477.
With the new usb driver #4399 and usage of the updated dde_linux lx_eml/lx_kit
approach a much higher rate of IRQ session construction/destruction and signal
handler assignment (irq->sigh) are caused. This trickles down to the kernel,
which causes an hang of the AMD IOMMUs due to not setting reserved bits
adequately. The commit fixes the root cause in the kernel and add a guard
into core's to limit such driver behaviour.
Fixes#4482
