This patch uses dma_map_sg with phba->pcidev->dev instead of scsi_dma_map. scsi_dma_map doesn't work for NPIV since fc_vport->dev isn't fully initialized. check_addr() in arch/x86_64/kernel/pci-nommu.c leads to the crash since dev->dma_mask is NULL.

The Dell PERC2/QC erroneously was listed as having the 31 bit limit quirk on the interface allocations, removing the reference to repair this oversight. Also, the 2 quad pci address (family) match catch-all also retained the 31 bit limit and the 34 SG limit quirks in a paranoid move. Now, many years later, we find that none of the Adapters that did trigger with the family match had such quirks; these quirks are all limited to the 4 quad pci address matches to select legacy adapters already populated.

This patch is more like a spelling correction than a fix. It was discovered that if we had a busy status return from the Adapter for the SCSI srb command to a physical component, that we returned DID_NO_CONNECT rather than what one would expect DID_BUS_BUSY. Signed-off-by:

When reporting SCSI devices to the SCSI midlayer, use the FCP LUN as LUN reported to the SCSI layer. With this approach, zfcp does not have to create unique LUNS, and this code can be removed. Signed-off-by:

This patch is a reworked version of the data buffer accessors patch so that it applies on the NPIV sources.

Following the NPIV support, the following changes have been accumulated in the testing and qualification of the driver: - Fix affinity of ELS ring to slow/deferred event processing - Fix Ring attention masks - Defer dev_loss_tmo timeout handling to worker thread - Consolidate link down error classification for better error checking - Remove unused/deprecated nlp_initiator_tmr timer - Fix for async scan - move adapter init code back into pci_probe_one context. Fix async scan interfaces. - Expand validation of ability to create vports - Extract VPI resource cnt from firmware - Tuning of Login/Reject policies to better deal with overwhelmned targets - Misc ELS and discovery fixes - Export the npiv_enable attribute to sysfs - Mailbox handling fix - Add debugfs support - A few other small misc fixes: - wrong return values, double-frees, bad locking - Added adapter failure heartbeat Signed-off-by: -

NPIV support is added to the driver. It utilizes the interfaces of the fc transport for the creation and deletion of vports. Within the driver, a new Scsi_Host is created for each NPIV instance, and is paired with a new instance of a FC port. This allows N FC Port elements to share a single Adapter. Signed-off-by:

James Smart authored
NPIV support is only available via new adapter interface extensions, termed SLI-3. This interface changes some of the basic behaviors such as command and response ring element sizes and data structures, as well as a change in buffer posting. Note: the new firmware extensions are found only on our mid-range and enterprise 4Gig adapters - so NPIV support is available only on these newer adapters. The latest firmware can be downloaded from the Emulex support page. Signed-off-by:

James Smart authored
The driver is reorganized to separate the handling of the adapter from the handling of the FC port. Adapter handling includes submissions of command requests, receiving responses, and managing adapter resources. The FC port includes the discovery engine, login handling, and the mapping of a Scsi_Host on the "port". Although not a large functional change, as it touches core structures and functions, resulting in a large text delta. Signed-off-by:

If there is IO going to the volume while a hidden disk is being torn down, there is a case where we would return a DID_NO_CONNECT for IO sent to the volume. The end result is the volume goes read-only. This problem is due to the fact the firmware mapped target ids saved in per device object is phys_disk_num for hidden raid components, and target_id for the volume. There is a single case when both phys_disk_num and target_id are equal, so enters this issue. We fix this issue by checking the tflags when the device is torned down, insuring the IO being completed is meant for hidden raid component, not the volume. In addition to this fix, there are a couple other cases to address hidden raid components. For instance task_abort and device reset are not supported by mpt fw for hidden raid components, a bus reset would be required or target reset to volume. Signed-off-by:

I was investigating strange driver behaviour and thought that readable code and proper visible types might help explain why it didn't work right the moment a second SCB was outstanding to the controller. I was right - Cleanup, linuxise, demacro - Remove the BSD dual licence on the new work - Switch the if ALPHA to if __LP64__. (struct size is then right elsewhere) and then to CONFIG_64BIT as per Christoph's request - Fix the recursive locking on a reset. This is the only actual real code change (I hope ;)). I'm not clear what the right way to handle the BIOS param stuff is on n on x86-32/64. Using phys_to_virt and stuff is ugly and probably doesn't make sense elsewhere Still has a couple of odd things - and there seems to be a commonly shared EEPROM handling error several drivers have. Roughly speaking several SCSI drivers go try and read EEPROM It failed.. Write any changes between the default and the data we read Which is great as for some paths we've no idea what was in before, so each boot won't write it all back, won't checksum but will repeat the bug Also it can still sleep for a second with IRQ off, and there is some dubious looking error path locking marked FIXME in case anyone feels inspired to work on it. Not a newly introduced bug, and at least its now marked. Signed-off-by:

When a target scan is initiated from sysfs, we should check the portstate prior to invoke scsi_scan_target(). Otherwise scsi_scan_target() might oops as the rport might already been removed from the scsi host and the traversal from the rport to the scsi_host in scsi_scan_target() will fail. Also the portstate already told us that communication with the target has failed, so it's quite pointless to try. Signed-off-by:

Adds an eh_host_reset_handler to ibmvscsi which resets the connection to the vscsi server.
