Under certain workloads a command may seem to get lost. IOW, the Smart Array thinks all commands have been completed but we still have commands in our completion queue. This may lead to system instability, filesystems going read-only, or even panics depending on the affected filesystem. We add an extra read to force the write to complete. Testing shows this extra read avoids the problem. Signed-off-by: NMike Miller <mike.miller@hp.com> Cc: stable@kernel.org Signed-off-by: NJens Axboe <jaxboe@fusionio.com>

Add a mode of controller operation called Performant Mode. Even though cciss has been deprecated in favor of hpsa there are new controllers due out next year that HP must support in older vendor distros. Vendors require all fixes/features be upstream. These new controllers support only 16 commands in simple mode but support up to 1024 in performant mode. This requires us to add this support at this late date. The performant mode transport minimizes host PCI accesses by performinf many completions per read. PCI writes are posted so the host can write then immediately get off the bus not waiting for the writwe to complete to the target. In the context of performant mode the host read out to a controller pulls all posted writes into host memory ensuring the reply queue is coherent.

A recent commit broke the ia64 build: Author: Don Brace <brace@beardog.cce.hp.com> Date: Thu Nov 12 12:50:01 2009 -0600 cciss: Add enhanced scatter-gather support. because of this hunk: --- a/drivers/block/cciss.h +++ b/drivers/block/cciss.h +struct Cmd_sg_list { + SGDescriptor_struct *sgchain; + dma64_addr_t sg_chain_dma; + int chain_block_size; +}; The issue is that dma64_addr_t isn't #define'd on ia64. The way that we're using Cmd_sg_list.sg_chain_dma is to hold an address returned from pci_map_single(). + temp64.val = pci_map_single(h->pdev, + h->cmd_sg_list[c->cmdindex]->sgchain, + len, dir); + + h->cmd_sg_list[c->cmdindex]->sg_chain_dma = temp64.val; pci_map_single() returns a dma_addr_t too. This code will still work even on a 32-bit x86 build, where dma_addr_t is defined to be a u32 because it will simply be promoted to the __u64 that temp64.val is defined as. Thus, declaring Cmd_sg_list.sg_chain_dma as dma_addr_t is safe. Cc: Don Brace <brace@beardog.cce.hp.com> Cc: Stephen M.

On 64-bit systems, the improvement is even bigger.

Now that the cciss SCSI error handling routines operate with interrupts enabled, we no longer need to maintain the list of command completions that sendcmd() might inadvertantly scoop up, since now it only runs at driver init time, and there won't be any other commands for it to scoop up.

The MSA2012 cannot inform the driver of configuration changes since all management is out of band. This is a departure from any storage we have supported in the past. We need some way to detect changes on the topology so we implement this kernel thread. In some instances there's nothing we can do from the driver (like LUN failure) so just print out a message. In the case where logical volumes are added or deleted we call rebuild_lun_table to refresh the driver's view of the world.

This patch makes the rebuild_lun_table smart enough to not rip a logical volume out from under the OS. Without this fix if a customer is running hpacucli to monitor their storage the driver will blindly remove and re-add the disks whenever the utility calls the CCISS_REGNEWD ioctl. Unfortunately, both hpacucli and ACUXE call the ioctl repeatedly. Customers have reported IO coming to a standstill. Calling the ioctl is the problem, this patch is the fix.

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.

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 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.
