STRUCT CCW_DEVICE(9) The ccw bus STRUCT CCW_DEVICE(9)NAMEstruct_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
ccwlock
pointer to device lock
id
id of this device
drv
ccw driver for this device
dev
embedded device structure
online
online status of device
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).
