* [SCSI] scsi tgt: scsi target user and kernel communication interfaceFUJITA Tomonori2006-11-25
| | | | | | | | | | | | | | | | The user-space daemon and tgt kernel module need bi-directional kernel/user high-performance interface, however, mainline provides no standard interface like that. This patch adds shared memory interface between kernel and user spaces like some other drivers do by using own character device. The user-space daemon and tgt kernel module creates shared memory via mmap and use it like ring buffer. poll (kernel to user) and write (user to kernel) system calls are used for notification.

* [SCSI] scsi tgt: scsi target lib functionalityFUJITA Tomonori2006-11-25
| | | | | | | | | | | | | | | | | The core scsi target lib functions. TODO: - mv md/dm-bio-list.h to linux/bio-list.h so md and us do not have to do that weird include. - convert scsi_tgt_cmd's work struct to James's execute code. And try to kill our scsi_tgt_cmd. - add host state checking. We do refcouting so hotplug is partially supported, but we need to add state checking to make it easier on the LLD.

* [SCSI] export scsi-ml functions needed by tgt_scsi_lib and its LLDsFUJITA Tomonori2006-11-25
| | | | | | | | | | | | | | | | | | | | | | | This patch contains the needed changes to the scsi-ml for the target mode support. Note, per the last review we moved almost all the fields we added to the scsi_cmnd to our internal data structure which we are going to try and kill off when we can replace it with support from other parts of the kernel. The one field we left on was the offset variable. This is needed to handle the case where the target gets request that is so large that it cannot execute it in one dma operation. So max_secotors or a segment limit may limit the size of the transfer. In this case our tgt core code will break up the command into managable transfers and send them to the LLD one at a time. The offset is then used to tell the LLD where in the command we are at. Is there another field on the scsi_cmd for that?

* [SCSI] qla2xxx: defer topology discovery to DPC thread during initialization.Andrew Vasquez2006-11-22
| | | | | | | | | | | | | | | | | | | | | | | | | | Modify intialization semantics: - perform basic hardware configuration only (as usual) - allocate resources - load and execute firmware - defer link (transport) negotiations to the DPC thread - again the code in qla2x00_initialize_adapter() to stall probe() completion was needed for legacy-style scanning. - DPC thread stalls until probe() complete. - before probe() completes, set DPC flags to perform loop-resync logic (similar to what's done during cable-insertion/removal). Benefits: user does not have to wait 20+ seconds in case the FC cable is unplugged during driver load, code consolidation (removal of redundant link negotiation logic during initialize_adaoter()), and finilly, the driver no longer needs to defer the fc_remote_port_add() calls to hold off lun-scanning prior to returning from the probe() function.

* [SCSI] Make scsi_scan_host work for drivers which find their own targetsMatthew Wilcox2006-11-22
| | | | | | | | | | | | | If a driver can find its own targets, it can now fill in scan_finished and (optionally) scan_start in the scsi_host_template. Then, when it calls scsi_scan_host(), it will be called back (from a thread if asynchronous discovery is enabled), first to start the scan, and then at intervals to check if the scan is completed. Also make scsi_prep_async_scan and scsi_finish_async_scan static. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] aacraid: Abort management FIBsMark Haverkamp2006-11-22
| | | | | | | | | | | | | | | | | | | | | | | | Received from Mark Salyzyn: Add code to abort outstanding management ioctl fibs when the blinkLED recovery is performed. This code is 'clunky' and does not have any real feedback in that the reset could progress before the user application has gotten it's notification of command completion. We put a schedule() call to delay just the right amount for most cases, because we tried a spin and still managed to find cases where we would spin forever waiting for the management application to acknowledge the impending doom surrounding the cause of the BlinkLED. Will cause an oops in the context of the management application if we proceed too quickly. I view this as the lesser of many evils since currently if there are outstanding management ioctls during a need to reset/recover the adapter, the management application just locks up and waits forever. The best practices fix for this problem not going to be simple or easy (at least the fixes I imagine today); and we found a balance between the needs of the driver to proceed, and the applications that locked or confused that would hold back the driver. I just do not like the idea of a kernel oops in an application to deal with low priority, sluggish or misbehaving applications.

Again. This same bug has now been introduced twice: it was done earlier by commit b8d35192c55fb055792ff0641408eaaec7c88988, only to be reverted last time in commit 72945b2b90a5554975b8f72673ab7139d232a121. We must NOT try to queue up notify handlers to another thread than the normal ACPI execution thread, because the notifications on some systems seem to just keep on accumulating until we run out of memory and/or threads. Keeping events within the one deferred execution thread automatically throttles the events properly. At least the Compaq N620c will lock up completely on the first thermal event without this patch reverted.
