device_get_sysctl_ctx, device_get_sysctl_tree — manipulate the sysctl oid tree for driver specific sysctl nodes
#include <sys/param.h> #include <sys/bus.h> struct sysctl_ctx_list * device_get_sysctl_ctx(device_t dev); struct sysctl_oid * device_get_sysctl_tree(device_t dev);
The newbus system automatically adds a sysctl node for each device in the system. This node can be accessed with the device_get_sysctl_tree() function. The context for the node can be obtained with the device_get_sysctl_ctx() function.
