      [SCSI] update fc_transport for removal of block/unblock functions · 19a7b4ae
      James.Smart@Emulex.Com authored
      
      
      We recently went back to implement a board reset. When we perform the
      reset, we wanted to tear down the internal data structures and rebuild
      them. Unfortunately, when it came to the rport structure, things were
      odd. If we deleted them, the scsi targets and sdevs would be
      torn down. Not a good thing for a temporary reset. We could block the
      rports, but we either maintain the internal structures to keep the
      rport reference (perhaps even replicating what's in the transport),
      or we have to fatten the fc transport with new search routines to find
      the rport (and deal with a case of a dangling rport that the driver
      forgets).
      
      It dawned on me that we had actually reached this state incorrectly.
      When the fc transport first started, we did the block/unblock first, then
      added the rport interface. The purpose of block/unblock is to hide the
      temporary disappearance of the rport (e.g. being deleted, then readded).
      Why are we making the driver do the block/unblock ? We should be making
      the transport have only an rport add/delete, and the let the transport
      handle the block/unblock.
      
      So... This patch removes the existing fc_remote_port_block/unblock
      functions. It moves the block/unblock functionality into the
      fc_remote_port_add/delete functions.  Updates for the lpfc driver are
      included. Qlogic driver updates are also enclosed, thanks to the
      contributions of Andrew Vasquez. [Note: the qla2xxx changes are
      relative to the scsi-misc-2.6 tree as of this morning - which does
      not include the recent patches sent by Andrew]. The zfcp driver does
      not use the block/unblock functions.
      
      One last comment: The resulting behavior feels very clean. The LLDD is
      concerned only with add/delete, which corresponds to the physical
      disappearance.  However, the fact that the scsi target and sdevs are
      not immediately torn down after the LLDD calls delete causes an
      interesting scenario... the midlayer can call the xxx_slave_alloc and
      xxx_queuecommand functions with a sdev that is at the location the
      rport used to be. The driver must validate the device exists when it
      first enters these functions. In thinking about it, this has always
      been the case for the LLDD and these routines. The existing drivers
      already check for existence. However, this highlights that simple
      validation via data structure dereferencing needs to be watched.
      To deal with this, a new transport function, fc_remote_port_chkready()
      was created that LLDDs should call when they first enter these two
      routines. It validates the rport state, and returns a scsi result
      which could be returned. In addition to solving the above, it also
      creates consistent behavior from the LLDD's when the block and deletes
      are occuring.

      [SCSI] qla2xxx: Add support to dynamically enable/disable ZIO. · 4fdfefe5
      Andrew Vasquez authored
      
      
      ISP23xx and ISP24xx chips have support for an adaptive
      method of posting SCSI command completions for multiple SCSI
      commands during a single system interrupt.
      
      SCSI commands are placed on the system response queue
      without interrupting the host until 1) a delay timer
      expires; or 2) a SCSI command completes with an error.
      
      As long as the host software (qla2xxx) services the response
      queue for completions (this polling is done during
      queuecommand()) within the 'delay timer' period, the
      firmware will not generate system interrupt.

      [SCSI] qla2xxx: Correct issue where fcport is prematurely marked DEAD. · 0eedfcf0
      Andrew Vasquez authored
      
      
      The non-handled failure cases of the Fabric Login mailbox
      command handling logic would incorrectly mark the fcport as
      dead and not allow the standard port-down-retry-count logic
      to manage the transition.

      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!
