| 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¶
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

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).
