2008-04-07[SCSI] qla2xxx: Cruft cleanup of functions and structures.Andrew Vasquez
Strip unused (DEBUG-ONLY) enabled functions, inlines, useless wrappers, and unused DPC flags from the code. Another step in the migration towards a cleaner (less-crusty) driver.

2005-10-28[SCSI] qla2xxx: Add support to dynamically enable/disable ZIO.Andrew Vasquez
ISP23xx and ISP24xx chips have support for an adaptive method of posting SCSI command completions for multiple SCSI commands during a single system interrupt. SCSI commands are placed on the system response queue without interrupting the host until 1) a delay timer expires; or 2) a SCSI command completes with an error. As long as the host software (qla2xxx) services the response queue for completions (this polling is done during queuecommand()) within the 'delay timer' period, the firmware will not generate system interrupt.

2005-09-04[SCSI] qla2xxx: Remove redundant call to pci_unmap_sg().Andrew Vasquez
In a corner-case failure where the request-q does not contain enough entries for a given request, pci_unmap_sg() would be called twice. Remove direct call and let the failure-path logic handle the unmapping. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2005-04-18[PATCH] qla2xxx: cleanup DMA mappings...
Don't use cmd->request->nr_hw_segments as it may not be initialized (SG_IO in particular bypasses anything that initializes this and just uses scsi_do_req to insert a scsi_request directly on the head of the queue) and a bogus value here can trip up the checks to make sure that the number of segments will fit in the queue ring buffer, resulting in commands that are never completed. Fix up several issues with PCI DMA mapping and failure to check return values on the mappings. Make the check for space in the ring buffer happen after the DMA mapping is done since any checks done before the mapping has taken place are bogus. Doug Ledford <dledford@redhat.com>.

2005-04-18[PATCH] qla2xxx: remove internal queuing...
Remove internal command queuing from the driver. As is, this driver cannot tolerate cable-pulls as I/Os will begin to fail by the upper layers. o Should be used in conjuction with the 11-fc_rport_adds_2.diff patch. o Removes qla_listops.h file -- no longer needed.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
