For very common code sections, which become specific to the interface type, the driver uses an indirect function call. The function is set at initialization. For less common sections, such as initialization, the driver looks at the interface type and calls the routines relative to the interface.

| | | | | | | | | | | | | | | 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 : Miscellaneous FixesJames Smart2008-07-121-6/+7
| | | | | | | | | | | | | | | | | | Miscellaneous Fixes: - Fix bug in mbox sysfs interface that locked in EAGAIN if discovery stalled. - Fix missing error message when npiv and loop are true when link up occurs. - Fix panic in lpfc_scsi_cmd_iocb_cmpl: scsi_buf was NULL, but created race conditions with other code paths. - Fix error in sysfs mailbox structure that didn't rezero on next use. - Add missing mempool_free() to attachment failure path - Fix missing put of ndlp structure during driver unload. - Fix applications unable to send mailbox commands during discovery. - Remove unused argument (type) from function lpfc_post_buffer() API - Fix vport name is not shown after hbacmd vportcreate. - Remove repeated code statements.

* [SCSI] lpfc 8.2.7 : Rework the worker threadJames Smart2008-07-121-18/+18
| | | | | | | | | 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 Smart2008-04-101-11/+9
| | | | | | | | | | | | | | | | | | 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 : PCI Parity and EEH handling fixesJames Smart2008-04-101-2/+1
| | | | | | | | | | | PCI Parity and EEH handling Fixes: - Under a PCI Data Parity Error, remove a completion routine callback that was on a command that we had already failed and released. - Under PCI parity error, we were not reinstalling the interrupt handler in the slot_reset callback, so we never became functional again.

* [SCSI] lpfc 8.2.6 : Multiple discovery fixesJames Smart2008-04-101-33/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
