| STRUCT CCW_DEV_ID(9) | The ccw bus | STRUCT CCW_DEV_ID(9) |
NAME¶
struct_ccw_dev_id - unique identifier for ccw devices
SYNOPSIS¶
struct ccw_dev_id {
u8 ssid;
u16 devno;
};
MEMBERS¶
ssid
subchannel set id
devno
device number
DESCRIPTION¶
This structure is not directly based on any hardware structure. The hardware identifies a device by its device number and its subchannel, which is in turn identified by its id. In order to get a unique identifier for ccw devices across subchannel sets, struct ccw_dev_id has been introduced.
