[S390] cio: trigger subchannel event at resume time

2010-02-26T21:37:30Z

ccw_device_pm_restore: trigger subchannel event to better handle changes to the subchannel device. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: make wait_events interruptible

2010-02-26T21:37:29Z

Make the potentially long blocking wait_event's used by the cio settle mechanism interruptible. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: consolidate workqueues

2010-02-26T21:37:29Z

We used to maintain 2 singlethreaded workqueues for synchronization and to trigger work from interrupt context. Since our latest cio changes we only use one of these workqueues. So get rid of the unused workqueue, rename the remaining one to "cio_work_q" and move its ownership to the channel subsystem driver. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: introduce subchannel todos

2009-12-07T11:51:30Z

Ensure that current and future users of sch->work do not overwrite each other by introducing a single mechanism for delayed subchannel work. Signed-off-by: Peter Oberparleiter Signed-off-by: Martin Schwidefsky

[S390] cio: idset use actual number of ssids

2009-09-22T20:58:42Z

The functions idset_sch_new and for_each_subchannel_staged use different values for the number of subchannel sets. Make it consistent by changing idset_sch_new to also use the actual number of subchannel sets. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: introduce css_settle

2009-09-22T20:58:41Z

Introduce the css_driver callback settle which can be implemented by a subchannel driver to wait for the subchannel type specific asynchronous work to finish. In channel_subsystem_init_sync we call that for each subchannel driver. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: Add chsc subchannel driver.

2008-07-14T08:02:12Z

This patch adds a driver for subchannels of type chsc. A device /dev/chsc is created which may be used to issue ioctls to: - obtain information about the machine's I/O configuration - dynamically change the machine's I/O configuration via asynchronous chsc commands Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] css: Use css_device_id for bus matching.

2008-07-14T08:02:12Z

css_device_id exists, so use it for determining the right driver (and add a match_flags which is always 1 for valid types). Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] cio: Repair chpid event handling.

2008-07-14T08:02:11Z

Passing the affected chpid in chp_event() worked only by chance since chpid is the first element in res_acc_data. Make it work properly by generalizing res_acc_data as chp_link and always passing around a properly filled out chp_link structure in chp_event().
