2007-08-01[SCSI] lpfc 8.2.2 : Rework the lpfc_printf_log() macroJames Smart
Rework the lpfc_printf_log() macro so that logging is enabled on a per-vport basis. Used to be on a physical-port basis, thus logging with large numbers of vports became a mess. Required redefinition of the macro, and an update of every use. Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2007-06-17[SCSI] lpfc: NPIV: add NPIV support on top of SLI-3James Smart
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.

2007-06-17[SCSI] lpfc: NPIV: add SLI-3 interfaceJames Smart
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 <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-06-17[SCSI] lpfc: NPIV: split portsJames Smart
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.

dual channel adapters Introduce lpfc_reset_barrier() function for resets on dual channel adapters Workaround for a hardware errata on dual channel asics. There is a potential for the chip to lock up on a reset if a shared dma engine is in use. The (ugly) work around requires a reset process which uses a mailbox command to synchronize the independent channels prior to the reset to avoid the issue. Unfortunately, the timing windows required to ensure this workaround succeeds are very specific, meaning we can't release the cpu during the barrier.
