scsi: aacraid: change event_wait to a completion

2018-12-13T01:35:33+00:00

The event_wait semaphore has completion semantics, so we can
change it over to the completion interface for clarity without
changing the behavior.

scsi: aacraid: stop using deprated get_seconds()

2018-06-26T15:57:01+00:00

get_seconds() can overflow on 32-bit architectures and is deprecated
because of that. The use in the aacraid driver has the same problem due to
a limited firmware interface, it also overflows in the year 2106.

This changes all calls to get_seconds() to the non-deprecated
ktime_get_real_seconds(), which unfortunately doesn't solve that problem
but gets rid of one user of the deprecated interface.

2018-04-05T22:05:53+00:00

Pull SCSI updates from James Bottomley:
 "This is mostly updates of the usual drivers: arcmsr, qla2xx, lpfc,
  ufs, mpt3sas, hisi_sas.

  In addition we have removed several really old drivers: sym53c416,
  NCR53c406a, fdomain, fdomain_cs and removed the old scsi_module.c
  initialization from all remaining drivers.

  Plus an assortment of bug fixes, initialization errors and other minor
  fixes"

scsi: aacraid: Auto detect INTx or MSIx mode during sync cmd processing

2018-02-14T02:37:04+00:00

During sync command processing, if legacy INTx status indicates command
is not completed, sample the MSIx register and check if it indicates
command completion, set controller MSIx enabled flag.

scsi: aacraid: Implement DropIO sync command

2018-02-14T02:37:03+00:00

IOP_RESET takes a long time to complete. If controller is in a state
where we can bring it back with init struct, send a DropIO sync command
instead.

 - If controller is faulted perform standard IOP_RESET in aac_srcv_init.

 - If controller is not faulted get adapter properties and extended
   properties.

 - Update the sa_firmware variable and determine if DropIO request is
   supported.

 - Issue DropIO request, and get the number of outstanding commands.

 - If all commands are complete with success (CT_OK), consider IOP_RESET
   is complete.

 - If any commands timeout, Perform the IOP_RESET.

scsi: aacraid: Perform initialization reset only once

2017-11-21T03:32:00+00:00

Currently the driver accepts two ways of requesting an initialization
reset on the adapter: by passing aac_reset_devices module parameter,
or the generic kernel parameter reset_devices.

It's working as intended...but if we end up reaching a scsi hang and
the scsi EH mechanism takes place, aacraid performs resets as part of
the scsi error recovery procedure. These EH routines might reinitialize
the device, and if we have provided some of the reset parameters in the
kernel command-line, we again perform an "initialization" reset.

So, to avoid this duplication of resets in case of scsi EH path, this
patch adds a field to aac_dev struct to keep per-adapter track of the
init reset request - once it's done, we set it to false and don't
proactively reset anymore in case of reinitializations.
