* [S390] Support for disconnected devices reappearing on another subchannel.Cornelia Huck2006-12-081-0/+2
| | | | | | | | | | | - create a 'pseudo_subchannel' per channel subsystem (the 'orphanage') - use the orphanage as a shelter for ccw_devices that can't remain on the same subchannel Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

* [S390] cio: Make ccw_device_register() static.Cornelia Huck2006-10-271-1/+0
| | | | | | | | | ccw_device_register() is only called from io_subchannel_register() and io_subchannel_probe() and will never be called for possible non-io subchannels. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] cio: Remove grace period for vary off chpid.Cornelia Huck2006-10-111-1/+0
| | | | | | | | | | | | The grace period handling introduced needless complexity. It didn't help the dasd driver (which can handle terminated I/O just well), and it doesn't help for long running channel programs (which won't complete during the grace period anyway). Terminating I/O using a path that just disappeared immediately is much more consistent with what the user expects.

* [S390] rework of channel measurement facility.Cornelia Huck2006-06-291-0/+4
| | | | | | | | | | | | | | | | Fixes for several channel measurement facility bugs: * Blocks copied from the hardware might not be consistent. Solve this by moving the copying into idle state and repeating the copying. * avg_sample_interval changed with every read, even though no new block was available. Solve this by storing a timestamp when the last new block was received. * Several locking issues. * Measurements were not reenabled after a disconnected device became available again. * Remove #defines for ioctls that were never implemented.

* [S390] cio async subchannel reprobe.Peter Oberparleiter2006-06-291-0/+6
| | | | | | | | | Changes in the DASD driver require an asynchronous implementation of the subchannel reprobe loop. This loop was so far only used by the blacklisting mechanism but is now available to all CCW device drivers.

* [PATCH] s390: introduce struct subchannel_idCornelia Huck2006-01-061-0/+1
| | | | | | | | | | | | | | This patch introduces a struct subchannel_id containing the subchannel number (formerly referred to as "irq") and switches code formerly relying on the subchannel number over to it. While we're touching inline assemblies anyway, make sure they have correct memory constraints.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
