To signal that a device gets used and released by a session
introduce claim, release, and release all callbacks in the
USB interface of the C-API.
Ref genodelabs/genode#4483
* 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
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
Ref genodelabs/genode#4416
This patch introduces a C API to be used by input drivers to generate
Genode events. The initial version is limited to multitouch events only.
Fixes#4273
This commit introduces a C-API to the Uplink session, as well as to
serve as a Block service. It can be used by drivers ported from
C-only projects, like the Linux kernel, or BSD kernels for instance.
Fix#4226
