* [SCSI] megaraid_sas: Add support for Uneven Span PRL11Sumit.Saxena@lsi.com2013-06-255-50/+904
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MegaRAID older Firmware does not support uneven span configuration for PRL11. E.g User wants to create 34 Driver PRL11 config, it was not possible using old firmware, since it was not supported configuration in old firmware Old Firmware expect even number of Drives in each span and same number of physical drives at each span. Considering above design, 17 Drives at Span-0 and 17 drives at span-1 was not possible. Now, using this new feature Firmware and Driver both required changes. New Firmware can allow user to create 16 Drives at span-0 and 18 Drives at span-1. This will allow user to create 34 Drives Uneven span PRL11. RAID map is interface between Driver and FW to fetch all required fields(attributes) for each Virtual Drives. Since legacy RAID map consider Even Span design, there was no place to keep Uneven span information in existing Raid map. Because of this limitation, for Uneven span VD, driver can not use RAID map. This patch address the changes required in Driver to support Uneven span PRL11 support. 1. Driver will find if Firmware has UnevenSpanSupport or not by reading Controller Info. 2. If Firmware has UnvenSpan PRL11 support, then Driver will inform about its capability of handling UnevenSpan PRL11 to the firmware. 3. Driver will update its copy of span info on each time Raid map update is called. 4. Follow different IO path if it is Uneven Span. (For Uneven Span, Driver uses Span Set info to find relavent fields for that particular Virtual Disk) More verbose prints will be available by setting "SPAN_DEBUG" to 1 at compilation time.

* [SCSI] bfa: fix faulty handling of events in lps smVijay Mohan Guvva2013-06-041-1/+1
| | | | | | | | | | | | | | | | | | | When a switch disable/enable or a reboot is done, the HBA port gets an offline and a subsequent online notification. When the port comes up a link up notification is sent to bfa from the firmware. The bfa then send an FLOGI to the firmware which is sent out on the wire. The switch port meanwhile goes offline (presumably for diagnostics) which causes the switch not to respond to the FLOGI. The link down notification is sent to the HBA driver. However owing to a bug in the lps state machine handling the lps state machine does not move to sm_init state (it remains in sm_login state and send a login complete message to fcs). This results in a zero PID assignment as the login is not really complete. This fix is to correctly handle the events in lps state machine.

| | | | | | | | | | | Introduce eh_timeout which can be used for error handling purposes. This was previously hardcoded to 10 seconds in the SCSI error handling code. However, for some fast-fail scenarios it is necessary to be able to tune this as it can take several iterations (bus device, target, bus, controller) before we give up. Signed-off-by: Martin K.

* [SCSI] sd: avoid deadlocks when running under multipathHannes Reinecke2013-06-041-4/+25
| | | | | | | | | | | | | | | | | | | When multipathed systems run into an all-paths-down scenario all devices might be dropped, too. This causes 'del_gendisk' to be called, which will unregister the kobj_map->probe() function for all disk device numbers. When the device comes back the default ->probe() function is run which will call __request_module(), which will deadlock. As 'del_gendisk' typically does _not_ trigger a module unload the default ->probe() function is pointless anyway. This patch implements a dummy ->probe() function, which will just return NULL if the disk is not registered. This will avoid the deadlock. Plus it'll speed up device scanning.
