scsi: aacraid: Insure we don't access PCIe space during AER/EEH

2019-05-04T07:21:19+00:00

[ Upstream commit b6554cfe09e1f610aed7d57164ab7760be57acd9 ]

There are a few windows during AER/EEH when we can access PCIe I/O mapped
registers. This will harden the access to insure we do not allow PCIe
access during errors

scsi: aacraid: Fix performance issue on logical drives

2019-03-23T19:11:20+00:00

commit 0015437cc046e5ec2b57b00ff8312b8d432eac7c upstream.

Fix performance issue where the queue depth for SmartIOC logical volumes is
set to 1, and allow the usual logical volume code to be executed

scsi: aacraid: Fix missing break in switch statement

2019-03-13T21:01:30+00:00

commit 5e420fe635813e5746b296cfc8fff4853ae205a2 upstream.

Add missing break statement and fix identation issue.

This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.

scsi: communicate max segment size to the DMA mapping code

2019-01-23T01:40:59+00:00

When a host driver sets a maximum segment size we should not only propagate
that setting to the block layer, which can merge segments, but also to the
DMA mapping layer which can merge segments as well.

scsi: flip the default on use_clustering

2018-12-19T04:13:12+00:00

Most SCSI drivers want to enable "clustering", that is merging of
segments so that they might span more than a single page.  Remove the
ENABLE_CLUSTERING define, and require drivers to explicitly set
DISABLE_CLUSTERING to disable this feature.

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: change wait_sem to a completion

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

The wait_sem member is used like a completion, so we should
use the respective API. The behavior is unchanged.

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2018-10-25T14:40:30+00:00

Pull SCSI updates from James Bottomley:
 "This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380,
  qla2xxx, lpfc, libsas, hisi_sas.

  In addition there's a set of mostly small updates to the target
  subsystem a set of conversions to the generic DMA API, which do have
  some potential for issues in the older drivers but we'll handle those
  as case by case fixes.

  A new myrs driver for the DAC960/mylex raid controllers to replace the
  block based DAC960 which is also being removed by Jens in this merge
  window.

  Plus the usual slew of trivial changes"

[ "myrs" stands for "MYlex Raid Scsi". Obviously. Silly of me to even
  wonder. There's also a "myrb" driver, where the 'b' stands for
  'block'. Truly, somebody has got mad naming skillz. - Linus ]
