[SCSI] bfa: Introduced initiator based lun masking feature.

2011-07-27T10:55:03+00:00

- Added support to enable initiator based lun masking.
- Initiator based Lun masking works similar to zoning where
  initiator port is allowed to see only those LUNs which are
  configured to be seen.

[SCSI] bfa: Add support to store driver configuration in flash.

2011-07-27T10:54:03+00:00

- Added dconf (Driver Config) BFA sub-module.
- The dconf sub-module provides interfaces and manages flash writes
  to the flash DRV parition.
- dconf sub-module also ensures that the whole 64K DRV partition is updated
  on a flash write.

[SCSI] bfa: Added support to collect and reset fcport stats

2011-07-27T10:48:52+00:00

- Added support to collect and reset fcport stats.
- Modified design to allow multiple requests for fcport stats.
  - fcport will remember the stats request in its stats_pending
    queue and service each of the queued requests after receiving
    a firmware response for the prior request.

[SCSI] bfa: Update RME interrupt handling.

2011-07-27T10:44:48+00:00

- Made changes to always acknowledge RME interrupt and update
  consumer index (CI) when RME interrupt is generated.
- Made changes to have ASIC specific hw_rspq_ack() handler.

- Added support to collect driver/fw stats.
- Added support to perform adapter/ioc enable, disable operations.

[SCSI] bfa: DMA memory allocation enhancement.

2011-06-29T22:11:09+00:00

- Modified the design such that each BFA sub-module will provide
  the amount of DMA and KVA memory needed by it and queues the
  same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
  the dma and kva memory requested by sub-modules.
- The change is needed to avoid requesting the aggregate amount of memory
  needed by all the BFA sub-modules as one contiguous chunk.

[SCSI] bfa: Brocade-1860 Fabric Adapter vHBA support.

2011-06-29T22:02:28+00:00

- Introduced partitioning of the BFA resources.
- Added h/w queue ID in CPE messages, firmware uses h/w queue ID
  from messages to pick a matching RME queue.
- Added message header to bfa_reqq_produce(). h/w queue ID is set
  in the message header and firmware modules use h/w queue ID from
  message header instead of from cpqe event.
- Made changes to allow using all 256 queues of Brocade-1860 asic.
  Previously only a single queue per queue group was used.
- Added function tag to BFI message header. Only used by FC BFI
  messages.  Used to translate host tag to firmware tag. bfa_lpuid()
  is changed to bfa_fn_lpu() that encodes both PCI function and port
  ID in BFI message header.

[SCSI] bfa: Added Fabric Assigned Address(FAA) support

2011-06-29T21:59:01+00:00

- Updated/added data structures and definitions to support FAA protocol.
- Modified the IOC state machine to support FAA.
- Introduced FAA feature configuration - enable/disable/query.

[SCSI] bfa: IOC and PLL init changes for Brocade-1860 Fabric Adapter.

2011-06-29T20:46:19+00:00

- Introduced IOC poll mechanism which replaces current interrupt
  based FW READY method.
- The timer based poll routine in IOC will query the ioc_fwstate
  register to see if there is a state change in FW, and sends the READY event.
- Bug fixes in the new asic PLL initialization.
- Added logic to handle CPE/RME queue interrupts before iocfc config done.
  1. Use the queue_process flag to see if iocfc configuration is done
     in INTX mode.
  2. Split the MSIX handler installation in two - one for IOC intr
     handler and the other for cpe/rme queue handler - and delay
     assigning queue handlers until iocfc config is done in MSIX mode.
