2011-06-29[SCSI] bfa: FCS bug fixes.Krishna Gudipati12-55/+288
- Added logic to initiate a PLOGI to the target, while processing a LOGO from the same target in Direct attach mode. - Added logic to generate a FCCT Reject indicating unsupported command, upon receiving FCCT/FCGS requests. - Added logic to set the fcpim in offline state and avoid any PRLI retries if a PRLI response is a reject with a reason Command Not Supported. - Updated the FDMI Supported/Current speeds. - Added logic to wait for the response from the firmware before sending ACC to PLOGI and transitioning to subsequent states - while processing an Incoming PLOGI in online state. - Added a wait state in the fcs_vport state machine - For case where FDISC is in progress and we get a vport delete request we wait for fdisc response and will transition to the appropriate state based on rsp status, else its causing both driver/fw resources to be not freed. - Remove the fc_credit_recovery module param.

2011-06-29[SCSI] bfa: DMA memory allocation enhancement.Krishna Gudipati13-569/+624
- 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 Gudipati12-118/+278
- 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: Brocade-1860 Fabric Adapter PLL init fixes.Krishna Gudipati9-132/+169
- If flash controller is halted unconditionally, this results in illegal write access to flash controller register domain. Since flash controller registers are only accessible once s_clk is started - added logic to check for WGN status and halt flash controller only if it is already running. - Added check to wait for flash controller halt to be completed before proceeding with s_clk/l_clk initializations. - Removed unnecessary reset logic for PMM 1T memory and moved memory initialization after flash access enable. - Disable Brocade-1860 asic MBOX interrupt before PLL initialization. - Remove reset enable for S_CLK/L_CLK after both PLL initializations are complete.

2011-06-29[SCSI] bfa: Driver initialization and model description fixKrishna Gudipati6-40/+101
- Moved FCS initialization, which internally does the im_port creation as well as the scsi_host creation before bfa_init.

2011-06-29[SCSI] bfa: FC credit recovery and misc bug fixes.Krishna Gudipati13-60/+129
- Introduce FC credit recovery. - Added module parameter to enable/disable credit recovery. Bug Fixes: - Removed check for ignoring plogi from initiator in switched fabric mode. - The ABTS for PLOGI is going out few millisecs earlier due to FW timer calibration (around 300 miilisecs earlier). So there is a window if an accept comes during this time HBA would have initiated an ABORT. - Added 1 to FC_ELS_TOV for compensating for FW timer.

fixes. - Added support for 16Gbps. - Added logic to flush pending mailbox command queue when IOC is disabled. - Fix to Halt the flash controller during fw initialization - since when asic blck is programmed flash controller's continuous access blocks f/w access to flash. - Added new asic based card types and modified IOC get card model routine. - Added PLL init fix to do LPU reset every time we do a memory initialization, since not doing so will cause LPU to be uninitialized during driver load. - Added fix to Halt flash controller before PLL initialization.

2011-06-29[SCSI] bfa: IOC and PLL init changes for Brocade-1860 Fabric Adapter.Krishna Gudipati10-137/+188
- 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.

2011-05-24[SCSI] bfa: kdump fixJing Huang4-1/+41
Root cause: When kernel crashes, bfa IOC state machine and FW doesn't get a notification and hence are not cleanly shutdown. So registers holding driver/IOC state information are not reset back to valid disabled/parking values. This causes subsequent driver initialization to hang during kdump kernel boot. Fix description: during the initialization of first PCI function, reset corresponding register when unclean shutown is detect by reading chip registers. This will make sure that ioc/fw gets clean re-initialization. Signed-off-by: Jing Huang <huangj@brocade.com> Signed-off-by: James Bottomley <jbottomley@parallels.com>
