2012-03-28[SCSI] bfa: Revised Fabric Assigned Address(FAA) feature implementation.Krishna Gudipati1-5/+4
Made changes to the Fabric Assigned Address(FAA) feature implementation. Introduced the IOCFC state machine, which now handles the FAA logic, IOC and BFA sub-modules enablement. Removed un-wanted FAA enable/disable routines; FAA is enabled by default. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
2011-07-27[SCSI] bfa: Introduced initiator based lun masking feature.Krishna Gudipati1-0/+16
- 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.

2011-07-27[SCSI] bfa: Add support to store driver configuration in flash.Krishna Gudipati1-0/+1
- 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.

2011-07-27[SCSI] bfa: Added support to collect and reset fcport statsKrishna Gudipati1-0/+21
- 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.

2011-07-27[SCSI] bfa: Update RME interrupt handling.Krishna Gudipati1-7/+6
- 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. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
2011-06-29[SCSI] bfa: Added support for flash configurationKrishna Gudipati1-22/+0
- Added flash sub-module. - Implemented the interface to read/erase/update flash partition. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
2011-06-29[SCSI] bfa: Extend BSG interface.Krishna Gudipati1-0/+1
- Added support to collect driver/fw stats. - Added support to perform adapter/ioc enable, disable operations. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
2011-06-29[SCSI] bfa: DMA memory allocation enhancement.Krishna Gudipati1-33/+17
- 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.

2011-06-29[SCSI] bfa: Brocade-1860 Fabric Adapter vHBA support.Krishna Gudipati1-5/+13
- 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.

2011-06-29[SCSI] bfa: Added Fabric Assigned Address(FAA) supportKrishna Gudipati1-0/+26
- 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. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
2011-06-29[SCSI] bfa: IOC and PLL init changes for Brocade-1860 Fabric Adapter.Krishna Gudipati1-5/+10
- 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.

2011-06-29[SCSI] bfa: Brocade-1860 Fabric Adapter Hardware EnablementKrishna Gudipati1-6/+8
- Added support for Brocade-1860 Fabric Adapter. - Made changes to support single firmware image per asic type. - Combined bfi_cbreg.h and bfi_ctreg.h defines into bfi_reg.h with only minimal defines used by host. - Added changes to setup CPE/RME Queue register offsets based on firmware response. - Removed queue register offset initializations and added register offsets to BFI config response message. - Added Brocade-1860 asic specific interrupt status definitions and mailbox interfaces.
