[S390] cio: fix sanity checks in device_ops.

2009-06-12T08:27:31Z

Some sanity checks in device_ops.c test the output of container_of macros to be !NULL. Test the input parameters instead. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: provide functions for fcx enabled I/O

2008-07-14T08:02:08Z

Provide functions for assembling and starting fcx enabled I/O request blocks. Signed-off-by: Peter Oberparleiter Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] cio: introduce fcx enabled scsw format

2008-07-14T08:02:07Z

Extend the scsw data structure to the format required by fcx. Also provide helper functions for easier access to fields which are present in both the traditional as well as the modified format. Signed-off-by: Peter Oberparleiter Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] cio: Make isc handling more robust.

2008-04-30T11:38:45Z

Introduce an ->isc field in the subchannel to store the desired interruption subclass, since sch->schib.pmcw.isc may be overwritten by the hardware on stsch() after machine checks. Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky

[S390] cio: Trigger verification on device/path not operational.

2008-04-17T05:46:57Z

Currently, we don't do much on no path or no device situations during normal user I/O, since we rely on reports regarding those events by the machine. If we trigger a path verification to bring our device state up-to-date, we (a) may recover from path failures earlier and (b) better handle situations where the hardware/hypervisor doesn't give us enough notifications.

[S390] cio: I/O subchannel specific fields.

2008-01-26T13:11:01Z

Some fields may be !0 only for I/O subchannels. Add some checks where required. Also adapt cio_enable_subchannel() to make the caller specify the intparm, which makes it more generic. Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky
