STRUCT CCW_DEVICE(9) The ccw bus STRUCT CCW_DEVICE(9)

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).
