[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().

[S390] cio: Cleanup crw interface.

2008-07-14T08:02:06Z

Eliminate the need for the machine check handler to call into the common I/O layer directly by introducing an interface to register handlers for crws per rsc. Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] cio: Rework css driver.

2008-07-14T08:02:05Z

Rework the css driver methods to provide sane callbacks for subchannels of all types. As a bonus, this cleans up and simplyfies the machine check handling for I/O subchannels a lot. Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

[S390] cio: Introduce modalias for css bus.

2008-07-14T08:02:05Z

Add modalias and subchannel type attributes for all subchannels. I/O subchannel specific attributes are now created in io_subchannel_probe(). modalias and subchannel type are also added to the uevent for the css bus. Also make the css modalias known.

[S390] cio: Register all subchannels.

2008-07-14T08:02:05Z

Register all valid subchannels, not only I/O subchannels. Move I/O subchannel specific initialization to io_subchannel_probe(). Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens
