| | | | | | | | | | | | | This patch changes the !blk-mq path to the same defaults as the blk-mq I/O path by always enabling block tagging, and always using host wide tags. We've had blk-mq available for a few releases so bugs with this mode should have been ironed out, and this ensures we get better coverage of over tagging setup over different configs.

| | | | | | | | | | | | | | | | | All drivers use the implementation for ramping the queue up and down, so instead of overloading the change_queue_depth method call the implementation diretly if the driver opts into it by setting the track_queue_depth flag in the host template. Note that a few drivers validated the new queue depth in their change_queue_depth method, but as we never go over the queue depth set during slave_configure or the sysfs file this isn't nessecary and can safely be removed.

* scsi: don't set tagging state from scsi_adjust_queue_depthChristoph Hellwig2014-11-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Remove the tagged argument from scsi_adjust_queue_depth, and just let it handle the queue depth. For most drivers those two are fairly separate, given that most modern drivers don't care about the SCSI "tagged" status of a command at all, and many old drivers allow queuing of multiple untagged commands in the driver. Instead we start out with the ->simple_tags flag set before calling ->slave_configure, which is how all drivers actually looking at ->simple_tags except for one worke anyway. The one other case looks broken, but I've kept the behavior as-is for now. Except for that we only change ->simple_tags from the ->change_queue_type, and when rejecting a tag message in a single driver, so keeping this churn out of scsi_adjust_queue_depth is a clear win. Now that the usage of scsi_adjust_queue_depth is more obvious we can also remove all the trivial instances in ->slave_alloc or ->slave_configure that just set it to the cmd_per_lun default.

This means even SCSI "untagged" commands will now have a tag, which is especially useful when using a host-wide tag map.

* | [SCSI] qla4xxx: correctly update session discovery_parent_idx.Manish Rangankar2013-10-251-19/+180
|/ | | | | | | | | | | | Earlier logic for driver created iscsi_session->discovery_parent_idx was to store ram index of a sendtarget entry, but driver frees sendtarget ram index as soon as firmware is done with discovery, which is available for further use. So changing the logic to point iscsi_session->discovery_parent_idx to store sendtarget flashnode index.

* [SCSI] qla4xxx: Implementation of ACB configuration during Loopback for ISP8042Nilesh Javali2013-09-031-1/+30
| | | | | | | | | | | | While loopback diagnostic is in progress, disable the ACB which resets all the active connections to target. Disable ACB would filter out all the DHCP multicast and broadcast packets which otherwise cause the diagnostic test to take longer time to complete or failures in some other cases.
