2006-01-08[PATCH] cciss: avoid defining useless MAJOR_NR macroChristoph Hellwig
This sneaked in with one of the updates. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
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.

2005-11-06[SCSI] cciss: scsi error handlingmike.miller@hp.com
This patch adds SCSI error handling code to the SCSI portion of the cciss driver. Signed-off-by: Stephen M. Cameron <steve.cameron@hp.com> Acked-by: Mike Miller <mike.miller@hp.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
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.

2005-09-13[PATCH] cciss: new disk register/deregister routinesMike Miller
This patch removes a couple of functions dealing with configuration and replaces them with new functions. This implementation fixes some bugs associated with the ACUXE. It also allows a logical volume to be removed from the middle without deleting all volumes behind it. If a user has 5 logical volumes and decides he wants to reconfigure volume number 3, he can now do that without removing volumes 4 & 5 first. This code has been tested in our labs against all application software.

2005-09-13[PATCH] cciss: busy_initializing flagMike Miller
This patch adds a flag called busy_initializing. If there are multiple controllers in a server AND the HP agents are running it's possible the agents may try to poll a card that is still initializing if the driver is removed and then added again.

2005-07-28[PATCH] cciss per disk queueMike Miller
This patch adds per disk queue functionality to cciss. Sometime back I submitted a patch but it looks like only part of what I needed. In the 2.6 kernel if we have more than one logical volume the driver will Oops during rmmod. It seems all of the queues actually point back to the same queue. So after deleting the first volume you hit a null pointer on the second one. This has been tested in our labs. There is no difference in performance, it just fixes the Oops.

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!
