CCW_DEVICE_START(9)		  The ccw bus		   CCW_DEVICE_START(9)

NAME
       ccw_device_start - start a s390 channel program

SYNOPSIS
       int ccw_device_start(struct ccw_device * cdev, struct ccw1 * cpa,
			    unsigned long intparm, __u8 lpm,
			    unsigned long flags);

ARGUMENTS
       cdev
	   target ccw device

       cpa
	   logical start address of channel program

       intparm
	   user specific interruption parameter; will be presented back to
	   cdev's interrupt handler. Allows a device driver to associate the
	   interrupt with a particular I/O request.

       lpm
	   defines the channel path to be used for a specific I/O request. A
	   value of 0 will make cio use the opm.

       flags
	   additional flags; defines the action to be performed for I/O
	   processing.

DESCRIPTION
       Start a S/390 channel program. When the interrupt arrives, the IRQ
       handler is called, either immediately, delayed (dev-end missing, or
       sense required) or never (no IRQ handler registered).

RETURNS
       0, if the operation was successful; -EBUSY, if the device is busy, or
       status pending; -EACCES, if no path specified in lpm is operational;
       -ENODEV, if the device is not operational.

CONTEXT
       Interrupts disabled, ccw device lock held
