Drivers: scsi: remove __dev* attributes.

2013-01-03T23:57:01Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand. Cc: Bill Pemberton Cc: Adam Radford Cc: "James E.J.

[SCSI] bfa: Firmware image naming convention update

2012-10-07T10:28:06Z

- Modified the firmware naming convention to contain the firmware image version (3.1.0.0). - The new convention is -.bin - The change will enforce loading only compatible firmware with this driver and also avoid over-writing the old firmware image in-order to load new version driver as the firmware names used to be the same.

[SCSI] bfa: Add support for max target ports discovery

2012-09-24T08:10:57Z

- Changes to avoid discovering NPIV port as remote port by the other NPIV ports created on same physical port when all the NPIV ports are part of the same zone in a fabric. - Provided mechanism to support maximum number of target ports for a given initiator port (physical port + NPIV ports) irrespective of the way in which the initiator and target ports are zoned in the fabric. - Introduced module_parameter max_rport_logins to restrict number of remote ports discovery which includes target and initiator remote ports.

[SCSI] bfa: Add PowerPC support and enable PCIE AER handling.

2012-09-24T08:10:56Z

- Added few missing endian swap changes to support BFA on PowerPC. - Added PCIE AER support to BFA: a) Implemented the PCI error handler entry points. b) Made changes to FCS state machine to handle STOP event from the PCI error detected entry point. c) Made changes to the IO Controller state machine to handle SUSPEND event from the PCI error detected entry point. d) Made changes to restart the BFA operations on a slot_reset completion.

[SCSI] bfa: Fix to defer vport delete handler invocation till firmware logo response.

2012-04-25T08:58:31Z

Made changes to avoid queuing the vport delete work to IM driver work queue in the bfa_fcb_lport_delete() - since at this stage we are not completely done with using the vport structure as we are still waiting for the LOGO response from the fw in online state or just doing some cleanup. Since queuing up the vport delete work at this stage will result in the FC transport layer to clean up the vport before we get the response from firmware. Made changes to queue the port delete work to the IM driver work queue - from the bfa_fcs_vport_free() function since at this state we are done with using the vport data structure and the FCS state machine is completely cleaned up.

[SCSI] bfa: Implement LUN Masking feature using the SCSI Slave Callouts.

2012-01-10T23:01:24Z

This patch re-implements LUN Masking feature using SCSI Slave Callouts. With the new design in the slave_alloc entry point; for each new LUN discovered we check with our internal LUN Masking config whether to expose or to mask this particular LUN. We return -ENXIO (No such device or address) from slave_alloc for the LUNs we don't want to be exposed. We also notify the SCSI mid-layer to do a sequential LUN scan rather than REPORT_LUNS based scan if LUN masking is enabled on our HBA port, since a -ENXIO from any LUN in REPORT_LUNS based scan translates to a scan abort. This patch also handles the dynamic lun masking config change from enable to disable or vice-versa by resetting sdev_bflags of LUN 0 appropriately.

[SCSI] bfa: Driver and BSG enhancements.

2011-06-29T22:28:17Z

- Added a new module parameter max_xfer_size to set the max_sectors in the scsi_host template. - Added logic to handle request_irq() failure so that msix vector resource is de-allocated immediately when failure happens. - BSG enhancements to collect vHBA releated info and port log. - Removed the workaround of incrementing the module refcnt on bsg request.

[SCSI] bfa: FCS bug fixes.

2011-06-29T22:12:11Z

- 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.
