      [SCSI] lpfc: bug fixes · 858c9f6c
      由 James Smart 提交于 
       Following the NPIV support, the following changes have been accumulated
 in the testing and qualification of the driver:

 - Fix affinity of ELS ring to slow/deferred event processing
 - Fix Ring attention masks
 - Defer dev_loss_tmo timeout handling to worker thread
 - Consolidate link down error classification for better error checking
 - Remove unused/deprecated nlp_initiator_tmr timer
 - Fix for async scan - move adapter init code back into pci_probe_one
   context. Fix async scan interfaces.
 - Expand validation of ability to create vports
 - Extract VPI resource cnt from firmware
 - Tuning of Login/Reject policies to better deal with overwhelmned targets
 - Misc ELS and discovery fixes
 - Export the npiv_enable attribute to sysfs
 - Mailbox handling fix
 - Add debugfs support
 - A few other small misc fixes:
    - wrong return values, double-frees, bad locking
 - Added adapter failure heartbeat

      [SCSI] lpfc: NPIV: add NPIV support on top of SLI-3 · 92d7f7b0
      由 James Smart 提交于 
      NPIV support is added to the driver.  It utilizes the interfaces of
the fc transport for the creation and deletion of vports. Within the
driver, a new Scsi_Host is created for each NPIV instance, and is
paired with a new instance of a FC port.  This allows N FC Port
elements to share a single Adapter.

      [SCSI] lpfc: NPIV: add SLI-3 interface · ed957684
      由 James Smart 提交于 
      NPIV support is only available via new adapter interface extensions,
termed SLI-3. This interface changes some of the basic behaviors such
as command and response ring element sizes and data structures, as
well as a change in buffer posting.  Note: the new firmware extensions
are found only on our mid-range and enterprise 4Gig adapters - so NPIV
support is available only on these newer adapters. The latest firmware
can be downloaded from the Emulex support page.

      [SCSI] lpfc: NPIV: split ports · 2e0fef85
      由 James Smart 提交于 
      The driver is reorganized to separate the handling of the adapter from
the handling of the FC port. Adapter handling includes submissions of
command requests, receiving responses, and managing adapter resources.
The FC port includes the discovery engine, login handling, and the
mapping of a Scsi_Host on the "port".  Although not a large functional
change, as it touches core structures and functions, resulting in a
large text delta.

      [SCSI] lpfc 8.1.1 : Add polled-mode support · 875fbdfe
      由 James.Smart@Emulex.Com 提交于 
      - Add functionality to run in polled mode only. Includes run time
  attribute to enable mode.
- Enable runtime writable hba settings for coallescing and delay parameters

Customers have requested a mode in the driver to run strictly polled.
This is generally to support an environment where the server is extremely
loaded and is looking to reclaim some cpu cycles from adapter interrupt
handling.

This patch adds a new "poll" attribute, and the following behavior:

if value is 0 (default):
  The driver uses the normal method for i/o completion. It uses the
  firmware feature of interrupt coalesing. The firmware allows a
  minimum number of i/o completions before an interrupt, or a maximum
  time delay between interrupts.  By default, the driver sets these
  to no delay (disabled) or 1 i/o - meaning coalescing is disabled.

  Attributes were provided to change the coalescing values, but it was
  a module-load time only and global across all adapters.
  This patch allows them to be writable on a per-adapter basis.

if value is 1 :
  Interrupts are left enabled, expecting that the user has tuned the
  interrupt coalescing values. When this setting is enabled, the driver
  will attempt to service completed i/o whenever new i/o is submitted
  to the adapter. If the coalescing values are large, and the i/o
  generation rate steady, an interrupt will be avoided by servicing
  completed i/o prior to the coalescing thresholds kicking in. However,
  if the i/o completion load is high enough or i/o generation slow, the
  coalescion values will ensure that completed i/o is serviced in a timely
  fashion.

if value is 3 :
  Turns off FCP i/o interrupts altogether. The coalescing values now have
  no effect. A new attribute "poll_tmo" (default 10ms) exists to set
  the polling interval for i/o completion. When this setting is enabled,
  the driver will attempt to service completed i/o and restart the
  interval timer whenever new i/o is submitted. This behavior allows for
  servicing of completed i/o sooner than the interval timer, but ensures
  that if no i/o is being issued, then the interval timer will kick in
  to service the outstanding i/o.
