The driver falls in line with the previous 'legacy_wifi_drv' component
where the ported wireless LAN stack and device driver is encapsulated
in a library. This library in return is used by the 'Libc::Component'
providing the necessary environment for the 'wpa_supplicant'.
In constrast to the old driver a 'wifi' VFS plugin is in charge of
initalizing the 'Lx_kit::Env' prior to executing any static
constructors.
Fixes#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.
The i2c code has a busy loop (see commit for the location), which expects that
the jiffies advances without a cooperative scheduling decision.
Issue #4450
Encountered on the Fuji5 where for reasons currently unknown the
first xHCI HC (0:0d.0) could not be initialize due to incomplete
interupt informations. The other HCs appear to work fine (tested
with a USB low-speed mouse).
required by the upcoming update of the intel display driver. Make this addition
explicit, because it triggers adjustment also on the new pc_usb_host_drv.
Issue #4450
.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.
* 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
The logic got accidentally reversed during the transition from the
legacy USB driver.
Since the function drops error details, this patch adds a diagnostic
message with the error code as returned by the Linux driver.
Adds a function to the USB part of the Genode's C API, to enable
usb_host drivers to acknowledge USB request in client's packet buffer
although they are not assigned to an USB device. The requests are
marked with a "no device" error.
This commit fixes a regression originally solved in genodelabs/genode#4149
