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.
In case where the ported driver or protocol stack is executed from
an already managed environment, e.g. the libc, the execution
of the static constructors will be performed at the appropriate
time.
Issue #4455.
If any PCI device reports 0 as interrupt PIN, drivers may try to force
MSI setup (e.g., xhci). So, we clamp the interrupt PIN to 1 to let
drivers finish initialization and don't bother the platform driver.
This commit removes all physical notions from the information given
to the Linux kernel regarding PCI BARs.
With the exception for the host bridge that needs to be located at
'0:00.0' as required by the Intel FB driver, all other devices are
announced at the PCI BUS in an ascending order.
Additionally the MMIO regions start at 1 GiB and are capped at 32 bit
to prevent unnecessary access to 64 bit addresses.
.SHELLFLAGS is extended by option pipefail to make pipes fail if any pipe
element fails. As .SHELLFLAGS is exported into sub-make instances it
must be unexported before calling third-party build systems recursively.
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
Fix#4443
* Unifies the declaration of callbacks which manage driver/client
shared dataspaces
* Move the Linux driver-specific callback implementation to the
lx_emul library from the PC's USB host driver
Fixgenodelabs/genode#4439
* Switch from the legacy usb_host driver to the new PC version
in recipes and automated tests
* Update documentation snippets
* Remove outdated, unused usb_rndis run-script
Fixgenodelabs/genode#4416
To make room for the re-newed usb_host_drv basing on Linux 5.14 and
the re-newed lx_kit/lx_emul we have to move the depot recipe and
consistently name the old drivers with a legacy_ prefix.
Ref genodelabs/genode#4416
The x86 platform driver uses a different API than the one for ARM for
which the lx_kit glue code was designed. Since the x86 platform driver
will eventually adopt a similar interface we implement a wrapper that
encapsulates the old interface.
Ref genodelabs/genode#4411
Until now, the lx_emul layer addressed a 5.11 Linux Kernel port,
now that we add new architectures it is better to update the default version
first. There are especially changes in the task_struct code,
and the signature of some functions in the paging subsystem changed.
