* [SCSI] lpfc 8.3.19: Add SLI4 FC Discovery supportJames Smart2010-12-211-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add SLI4 FC Discovery support - Replace READ_LA and READ_LA64 with READ_TOPOLOGY mailbox command. - Converted the old READ_LA structure to use bf_set/get instead of bit fields. - Rename HBA_FCOE_SUPPORT flag to HBA_FCOE_MODE. Flag now indicates function is running as SLI-4 FC or FCoE port. Make sure flag reset each time READ_REV completed as it can dynamically change. - Removed BDE union in the READ_TOPOLOGY mailbox command and added a define to define the ALPA MAP SIZE. Added FC Code for async events. - Added code to support new 16G link speed. - Define new set of values to keep track of valid user settable link speeds. - Used new link speed definitions to define link speed max and bitmap. - Redefined FDMI Port sppeds to be hax values and added the 16G value. - Added new CQE trailer code for FC Events. - Add lpfc_issue_init_vfi and lpfc_init_vfi_cmpl routines. - Replace many calls to the initial_flogi routine with lpfc_issue_init_vfi. - Add vp and vpi fields to the INIT_VFI mailbox command. - Addapt lpfc_hba_init_link routine for SLI4 use. - Use lpfc_hba_init_link call from lpfc_sli4_hba_setup. - Add a check for FC mode to register the FCFI before init link. - Convert lpfc_sli4_init_vpi to be called without a vpi (get it from vport).

* [SCSI] lpfc 8.3.18: Add logic to detect last devloss timeoutJames Smart2010-10-261-3/+5
| | | | | | | | | | | | | | | | | | Added driver logic to detect the last devloss timeout of remote nodes which was still in use of FCF. At that point, the driver should set the last in-use remote node devloss timeout flag if it was not already set and should perform proper action on the in-use FCF and recover of FCF from firmware, depending on the state the driver's FIP engine is in. Find eligible FCF through FCF table rescan or the next new FCF event when FCF table rescan turned out empty eligible FCF, and the successful flogi into an FCF shall clear the HBA_DEVLOSS_TMO flag, indicating the successful recovery from devloss timeout.

| | | | | | | | | | | | | | | Per the recent discussions at the Linux Plumbers Conference, when enabling MSI or MSI-X, generate a test interrupt to verify the interrupt routing is working properly. If the test interrupt fails, fall back to MSI first, and if that fails as well, to INTx. If the interrupt test fails with INTx, log an error and fail the PCI probe. Also changed the use of spin_(lock|unlock) to the _irq(save|restore) variants in the interrupt handlers because with multi-message MSI-X, both interrupt handlers can now run in parallel.

* [SCSI] lpfc 8.2.7 : Rework the worker threadJames Smart2008-07-121-4/+16
| | | | | | | | | Rework of the worker thread to make it more efficient. Make a finer-grain notfication of pending work so less time is spent checking conditions. Also made other general cleanups.

* [SCSI] lpfc 8.2.6 : Miscellaneous FixesJames Smart2008-04-101-1/+1
| | | | | | | | | | | | | | | | | | Miscellaneous Fixes - Allow WRITE_VPARAM command when the virtual port is in a stopped state - Fixed handling of our queue depth max that was unconditionally raising the depth on all vports, rather than just the vport affected. - Fix race in interrupt handler for mailbox processing that did not take out the host lock. - Removed unused functions: find_node, findnode_rpi, and fabric_abort_flogi - Correct misspelled word unsolicited in message 0146 - Correct HW-error 5 handling - it should not reset the adapter - Correct handling of IOCBs, which did not null out our pCmd field before invoking the midlayer io done function. - Changed our maximum supported target id to 4096 Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] lpfc 8.2.6 : Multiple discovery fixesJames Smart2008-04-101-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Multiple Discovery Fixes: - Fix race on discovery due to link events coinciding with vport_delete. - Use NLP_FABRIC state to filter out switch-based pseudo initiators that reuse the same WWNs. - Correct erroneous setting of DID=0 in lpfc_matchdid() - Correct extra reference count that was in the lookup path for the remoteid from an unsolicited ELS. - Correct double-free bug in els abort path. - Correct FDMI server discovery logic for switch that return a WWN of 0. - Fix bugs in ndlp mgmt when a node changes address - Correct bug that did not delete RSCNs for vports upon link transitions - Fix "0216 Link event during NS query" error which pops up when vports are swapped to different switch ports. - Add sanity checks on ndlp structures - Fix devloss log message to dump WWN correctly - Hold off mgmt commands that were interferring with discovery mailbox cmds - Remove unnecessary FC_ESTABLISH_LINK logic. - Correct some race conditions in the worker thread, resulting in devloss: - Clear the work_port_events field before handling the work port events - Clear the deferred ring event before handling a deferred ring event - Hold the hba lock when waking up the work thread - Send an acc for the rscn even when we aren't going to handle it - Fix locking behavior that was not properly protecting the ACTIVE flag, thus allowing mailbox command order to shift.
