Name

struct ccw_device — channel attached device

Synopsis

struct ccw_device {
  spinlock_t * ccwlock;
  struct ccw_device_id id;
  struct ccw_driver * drv;
  struct device dev;
  int online;
  void (* handler) (struct ccw_device *, unsigned long, struct irb *);
};

Members

spinlock_t * ccwlock: pointer to device lock
struct ccw_device_id id: id of this device
struct ccw_driver * drv: ccw driver for this device
struct device dev: embedded device structure
int online: online status of device
void (*) (struct ccw_device *, unsigned long, struct irb *) handler: interrupt handler

Description

handler is a member of the device rather than the driver since a driver can have different interrupt handlers for different ccw devices (multi-subchannel drivers).
