2017-12-04scsi: bfa: use proper time accessor for stats_reset_timeArnd Bergmann1-1/+1
We use the deprecated do_gettimeofday() function to read the current time when resetting the statistics in both bfa_port and bfa_svc. This works fine because overflow is handled correctly, but we want to get rid of do_gettimeofday() and using a non-monotonic time suffers from concurrent settimeofday calls and other problems. This uses the ktime_get_seconds() function instead, which does what we need here.

2012-10-07[SCSI] bfa: Add diagnostic port (D-Port) supportKrishna Gudipati1-0/+3
- Introduced support for D-Port which is a new port mode during which link level diagnostics can be run. - Provided mechanism to dynamically configure D-Port and initiate diagnostic tests to isolate any link level issues. - In D-Port mode, the HBA port does not participate in fabric or login to the remote device or run data traffic. - Diagnostic tests include running various loopback tests in conjunction with the attached device.

2011-06-29[SCSI] bfa: DMA memory allocation enhancement.Krishna Gudipati1-0/+3
- 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.
