On platforms different than x86 the subsys initcall `pci_subsys_init`
is not available. Therefore, we choose an alternative one here.

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.
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.

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.

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.
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.

This commit introduces support for building the WLAN driver for ARM
platforms. It makes the WPA supplicant and its support libraries
available for all platforms. It also seperates the PCI parts to
accommodate platforms where other bus protocols are used.
Issue #4813
The way the 'struct page' management is currently implemented it is
not safe to rely on it in case allocations share the same page. This
is in particular true where the virtual address is obtained by
querying the page object for maintaining the CPU caches.
Issue #4813
This commit updates the used firmware images for the iwlwifi device
to latest available ones (supported by the current 6.1.x driver).
It also removes old firmware images that by now are not used anymore.
Fixes#4807.
Recent devices are configured with 4096 RX pages that lead to an
increased memory usage. For the moment lower the amount to 2048
and treat in potientially lower throughput for more conservative
memory consumption.
Fixes#4801.
The get_cycles() call within the test doesn't apply to RDTSC
access when running on ARM but to arch_timer_read_counter, which
is an empty function pointer. By setting it to a function that
returns Genode::Trace::timestamp() we can enable the test for ARM.
Issue #4775
- move metadata specific to isochronous transfers from the descriptor
into the content of USB-session packets
- restore support for 32 in-flight packets in the USB C API
Fixes#4749
The additional files provide Chacha implementation in case
may_use_simd() returns false because in_interrupt() returns true.
Related to issue #4778, commit "lx_emul: track irq state changes"
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.
Ref genodelabs/genode#4778
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.
