* scsi: bfa: document overflow of io_profile_start_timeArnd Bergmann2017-12-041-2/+2
| | | | | | | | | | | | | | | io_profile_start_time() gets read using do_gettimeofday() and passed down as a 32-bit value through multiple functions. This will overflow in y2038 or y2106, depending on whether it gets interpreted as unsigned in the end. This changes do_gettimeofday() to ktime_get_real_seconds() and pushes the point at which it overflows to where we actually assign it to the bfa_fcpim_del_itn_stats_s structure, with an appropriate comment.

* [SCSI] bfa: Fix to handle firmware tskim abort request responseKrishna Gudipati2012-10-071-1/+3
| | | | | | | | | | - Enhance tracing to include both tskim tag and event. - Handle the tskim abort response from firmware in the tskim state machine cleanup state and proceed with the tskim cleanup.

* [SCSI] bfa: Revert back the current LUN Masking Implementation.Krishna Gudipati2012-01-101-7/+0
| | | | | | | | This patch reverts the current LUN Masking Implementation. We re-implemented this feature using the SCSI Slave Callout's as per the review comments. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
* [SCSI] bfa: Added support to configure lunmaskingKrishna Gudipati2011-07-271-0/+7

* [SCSI] bfa: Introduced initiator based lun masking feature.Krishna Gudipati2011-07-271-1/+11
| | | | | | | | | | - 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: DMA memory allocation enhancement.Krishna Gudipati2011-06-291-13/+15
| | | | | | | | | | | | | - 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.Krishna Gudipati2011-06-291-0/+4
| | | | | | | | | | | | | | | | | | - 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: io tag handling and minor bug fix.Krishna Gudipati2010-12-211-10/+12
| | | | | | | | | | | | | | | | | | | | | Fix iotag handling: 1) Update and check io tag for retry case. 2) Clearing upper 3 bits in io tag when an IO completes. The 3 upper bits in io tags are used for counting FCP exchange retry. Un-cleared bits will cause firmware to access invalid memory when the same io tag is used for an IO to a target that doesn't support FCP exchange retry. 3) Only check the effective bits when validating an iotag. Other minor fixes: 1) Added trace to get FC header type with assert of unhandled packet received. Ignore the type FC_TYPE_FC_FSS (FC_XS). 2) Fixed the adapter info display check - to check for fcmode flag even.
