2009-06-09cciss: decode unit attention in SCSI error handling codescameron@beardog.cca.cpqcorp.net
Make SCSI reset error handler decode unit attention ASC and after a target reset wait for a unit attention that indicates a reset occurred rather than just for any old unit attention.

2009-06-02cciss: fix SCSI device reset handlerStephen M. Cameron
Fix the SCSI reset error handler to send a working, properly addressed reset message to the target device and add code to wait for the target device to become ready by polling it with Test Unit Ready. The existing reset code was broken in that it didn't bother to set the 8-byte LUN address to anything besides zero, so the command was addressed to the controller, which pretended to the driver that the command succeeded, while doing nothing. Ages ago I tested this code, but unbeknownst to me, my test was flawed, and what I thought was a tape drive getting reset was actually nothing of the sort. Unfortunately, there is still lots of Smartarray firmware that doesn't handle doing target resets right, and this code won't help in those cases, but it also shouldn't make things worse in those cases than they already are.

2008-10-09cciss: Fix cciss SCSI rescan code to better notice device changesscameron@beardog.cca.cpqcorp.net
Fix cciss SCSI rescan code to better notice device changes. If you hot-unplug a tape drive, then hot-plug a different tape drive into the same slot in a storage enclosure, the cciss driver wouldn't notice anything had changed, as it was only looking at the LUN address and device type. Now it looks at the inquiry page 0x83 device identifier, and vendor and model strings as well. Signed-off-by: Stephen M.

2006-08-06[SCSI] Improve inquiry printingMatthew Wilcox
- Replace scsi_device_types array API with scsi_device_type function API. Gets rid of a lot of common code, as well as being easier to use. - Add the new device types in SPC4 r05a, and rename some of the older ones. - Reformat the printing of inquiry data; now fits on one line and includes PQ. I think I've addressed all the feedback from the previous versions.

2006-06-06[SCSI] fix up request buffer reference in various scsi driversChristoph Hellwig
Various scsi drivers use scsi_cmnd.buffer and scsi_cmnd.bufflen in their queuecommand functions. Those fields are internal storage for the midlayer only and are used to restore the original payload after request_buffer and request_bufflen have been overwritten for EH. Using the buffer and bufflen fields means they do very broken things in error handling. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-01-08[PATCH] cciss: adds MSI and MSI-X supportMike Miller
This creates a new function, cciss_interrupt_mode called from cciss_pci_init. This function determines what type of interrupt vector to use, i.e., MSI, MSI-X, or IO-APIC. One noticeable difference is changing the interrupt field of the controller struct to an array of 4 unsigned ints. The Smart Array HW is capable of generating 4 distinct interrupts depending on the transport method in use during operation. These are: #define DOORBELL_INT 0 Used to notify the contoller of configuration updates. We only use this feature when in polling mode. #define PERF_MODE_INT 0 Used when the controller is in Performant Mode. #define SIMPLE_MODE_INT 2 Used when the controller is in Simple Mode (current Linux implementation). #define MEMQ_INT_MODE 3 Not used. When using IO-APIC interrupts these 4 lines are OR'ed together so when any one fires an interrupt an is generated. In MSI or MSI-X mode this hardware OR'ing is ignored. We must register for our interrupt depending on what mode the controller is running. For Linux we use SIMPLE_MODE_INT exclusively at this time. Please consider this for inclusion.

2005-10-30[PATCH] fix missing includesTim Schmielau
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-09-13[PATCH] cciss: direct lookup for command completionsMike Miller
This patch changes the way we complete commands. In the old method when we got a completion we searched our command list from the top until we find it. This method uses a tag associated with each command (not SCSI command tagging) to index us directly to the completed command. This helps performance.

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!
