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.
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.
Issue #4663
In case the allocation fails for the largest possible connector mode,
try smaller modes. Additional add option to specify maximal resolution.
Issue #4659
Increase "assumed" internal kernel memory size based on available memory
to support allocation of framebuffer larger than 16M, which was before
hardcoded.

* Remove wrapper for legacy x86 platform API
* Move PCI configuration space quirks to corresponding driver
(pc_usb_host_drv, pc_wifi_drv, pc_intel_fb_drv)
* Adapt driver test run-scripts to changed configuration

m/udelay is called with closed interrupts. Linux contrib code expects no
other task to be run respectively to be re-scheduled. usleep_range leads to
executing other tasks, which causes assertions in "spinlock taken twice" or
"unexpected preempt count" errors, seen on runtime with wifi_drv and intel_fb.
The assertion triggered with the changes by #4562.
* Move common SMP and NO_HZ_IDLE variables and functions into
generic lx_emul shadow implementations, and integrate them
into the common lx_emul import rules
* Enable SMP and NO_HZ_IDLE within virt_linux kernel configuration
* Adapt pc drivers and wireguard accordingly
* Use original Linux softirq implementation in wireguard
* Remove erroneous softirq shadow implementation

Enables symetric-multi-processor support in the Linux kernel configuration
used as base for the driver ports for PC. This is done to be compliant with
common usage of x86 drivers today.
Moreover, this commit uses the original kernel source for softirq/tasklet
implementation to get rid of the insufficient shadow implementation
in the lx_emul sources.

The test runs as lx_user task and uses several *delay and wait queue test
cases happened to be used in real ported linux drivers. The test shows
the time spent with several time sources, e.g. jiffies, rdtsc,
lx_time_counter_count etc.
Issue #4540
Use common implementation used by wifi and (not merged) audio driver.
Avoid usage of lib/delay.c since lpj and loop_for_jiffies are not calibrated
for the ported drivers as done on native Linux during boot and leads to wrong
delays for usb and intel_fb.
Issue #4540
The 'iput()' function is called from '__sock_release()' when the sock
object has no valid file object. The release function on the other hand
is called when the supplicant closes a socket.
Fixes #xxx.
The 'with_libc' call at this point is not necessary and could be
harmful as it forces the usage of the user stack for the driver.
All code depending on this distinction should only be executed
from within the pthread.
Issue #4537.
Querying the RFKILL state led to execution of the Lx_kit::scheduler by
the pthread running the wpa_supplicant. As this may not happen the
RFKILL state is now solely managed by the driver and only the cached
state is read by the supplicant.
Fixes#4537.
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.
Fixes#4531
