SUBSYS_VIRTUAL_REGIS(9) Device drivers infrastructure SUBSYS_VIRTUAL_REGIS(9) NAME subsys_virtual_register - register a subsystem at /sys/devices/virtual/ SYNOPSIS int subsys_virtual_register(struct bus_type * subsys, const struct attribute_group ** groups); ARGUMENTS subsys virtual subsystem groups default attributes for the root device DESCRIPTION All 'virtual' subsystems have a /sys/devices/system/<name> root device with the name of the subystem. The root device can carry subsystem-wide attributes. All registered devices are below this single root device. There's no restriction on device naming. This is for kernel software constructs which need sysfs interface. COPYRIGHT Kernel Hackers Manual 3.11 November 2013 SUBSYS_VIRTUAL_REGIS(9)[top]
