* [PATCH] cciss: fix stall with softirq handling and CFQJens Axboe2006-07-25
| | | | | | | | | We need to postpone the queue startup until after the softirq handler has actually finished some requests, otherwise we could be racing with cciss_softirq_done() and not actually restart the queue handling. Signed-off-by: Jens Axboe <axboe@suse.de>

* [PATCH] cciss: adds MSI and MSI-X supportMike Miller2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] Add block_device_operations.getgeo block device methodChristoph Hellwig2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

* [BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()Tejun Heo2006-01-06
| | | | | | | | | | | | | | | | | add @uptodate argument to end_that_request_last() and @error to rq_end_io_fn(). there's no generic way to pass error code to request completion function, making generic error handling of non-fs request difficult (rq->errors is driver-specific and each driver uses it differently). this patch adds @uptodate to end_that_request_last() and @error to rq_end_io_fn(). for fs requests, this doesn't really matter, so just using the same uptodate argument used in the last call to end_that_request_first() should suffice. imho, this can also help the generic command-carrying request jens is working on.

| | | | | | | | | | | | | | | | The CCISS driver seems to loose track of DMA mappings created by it's fill_cmd() routine. Neither callers of this routine are extracting the DMA address created in order to do the unmap. Instead, they simply try to unmap 0x0. It's easy to see this problem on an x86_64 system when using the "swiotlb=force" boot option. In this case, the driver is leaking resources of the swiotlb and not causing a sync of the bounce buffer.

* [PATCH] cciss per disk queueMike Miller2005-07-28
| | | | | | | | | | | | | | | | | 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.

* [PATCH] cciss: remove partition info from CCISS_GETLUNINFOMike Miller2005-06-27
| | | | | | | | | | | | | | | This patch fulfills a promise I made to Christoph sometime back. I am removing the partition info from the CCISS_GETLUNINFO ioctl as I was informed my "driver had no damn business reading that structure." ;) The application folks are to use /proc or /sys for partition info from now on. I am only aware of a few apps that use this ioctl and I'm not sure they ever used the partition info.

* [PATCH] cciss: pci domain info pass 2Mike Miller2005-06-27
| | | | | | | | | | | | | This is pass 2 of my patch to add pci domain info to an existing ioctl. This time I insert the domain between dev_fn and board_id as Willy suggested and change the var to unsigned short to ease Christoph's concerns. Although I thought unsigned int was the correct var type for this. I also thought it didn't matter where I inserted it in the structure.

| | | | | | | | | | | This patch fixes a PCI ID I got wrong before. It also adds support for another new SAS controller due out this summer. I didn't have a marketing name prior to my last submission. Also modifies the copyright date range.
