The option is used during the generation of initcall_table.c.
However, it happens to strip the first argument following the option.
The long option --defined-only works as expected.
Issue #5155
When SMP is enabled multicore specific instructions (e.g., pldw) are
generated. These are not supported and lead to invalid instruction
faults on uni-processor systems (like Cortex-A8). Therefore, we disable
SMP for arm_v7 in Linux code. This requires also a switch from the RCU
tree implementation to RCU tiny, which we shadow and dummy implemented.

This commit updates lxip from version 4.4.3 to 6.1.20. It uses the
current lx_kit approach and is a shared library again. The stack has
been tested for x86_32/x86_64/arm_v6/arm_v7/arm_8.
The C-interface of the IP stack can be found under
lxip/include/genode_c_api/socket.h.
issue #5104
Functions registered with 'module_init' (i.e., '__define_initcalls'),
'OF_DECLARE', and 'DECLARE_PCI_FIXUP_CLASS_FINAL' used to be static
constructors and had be explicitly registered using
'exec_static_constructors' before executing any Linux code.
With this commit we remove the constructor attributes from these
functions and create a global function pointer in the form of
__initptr_<name>_<id>_<counter>_<line number of macro>
'import-lx_emul_common.inc' will collect these '__initptr' symbols after
the compile step and generate a 'lx_emul_register_initcalls' function
that executes the functions pointed to. This step is now automatically
performed in 'lx_emul_start_kernel'. This way a call to
'exec_static_constructors' can be omitted in case there are no other
constructors in place.
issue #5096
The management of Linux page structs is now tied to the life time of DMA
buffers. Thus, page structs are created when a buffer is allocated and
deallocated only when a buffer is freed - not on lx_emul_mem_free()
because DMA buffers are cached. Page struct refcounting was entirely
reworked in lx_emul/shadow/mm/page_alloc.c.
Fixes#4809
This commit adds support to initialize the timekeeping for
the Linux subsystem with the value from the RTC.
Only the seconds part of timespec64 is supported.
Issue genodelabs/genode#4957
The driver is superseded by the USB network driver (usb_net) which also
contains MBIM support for LTE modems previously provided by this
driver.
issue #4958
It turns out solely relying on the name of the compilation-unit
is not enough. In at least one multi-device driver, e.g. rtlwifi,
an equally called compilation-unit is found in several different
directories. There KBUILD_MODNAME is used to name the driver,
which fails later on as the driver framework refuses to register
an equally named driver twice.
Instead of only considering the name of the compilation-unit also
include the last element of the path to generate differentiating
KBUILD_MODNAME value.
Issue #4861.
Implement udelay for all architectures within common lx_emul code,
remove driver-specific version.
Always do busy looping in udelay and use cpu_relax()
like the original Linux code. Thereby, we profit from architecture specific
instructions (cpu cool down), and jiffies are updated if irqs are on.

To be able to check for interrupts being on or off,
the enabling and disabling is tracked in lx_emul.
When interrupts get received, they have to be turned off.

* 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

* 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

The location of the used 'source.list' file is hard-coded and will not
work when the ported driver is implemented as a shared library. For
this use-case provide means to set the location differently.
Issue #4455.
To support device-less protocol-stacks only ports, we can use a
Virt I/O Linux kernel flavor, and export the lx_kit/lx_emul parts
not depending on platform API and devices.
Ref #4397
* Drivers have to use lx_kit/memory_dma.cc
* Protocol-stacks use lx_kit/memory_non_dma.cc
* Moreover the device-dependent lx_emul parts get removed
from the common lx_emul import rules

Thise driver supports USB LTE modems for Huawais' ME906s through MBIM
and provides a traditional Nic session. The "control" interface is a
Terminal session, which can be used via libmbim/mbimcli.
