* [SCSI] megaraid_sas: Performance boost fixesSumit.Saxena@lsi.com2014-03-152-9/+42
| | | | | | | | | | | | | | Host lock is added back around queuecommand. Host lock removal can create race conditon between ISR path(when RAID map update interrupt is raised) and IO build path of driver, since IO build path is making use of RAID map, and in case of RAID map update interrupt, old RAID map copy is memset to zero, which some IOs may be referencing in build IO path. Changes done for performance boost- 1) Added code to set SMP IRQ affinity per CPU. 2) Pass MSI-x index, while issuing sysPD IO.

| | | | | | | | | | If consistent DMA mask is set to 64 bit, fall back to 32bit DMA mask and 32bit consistent DMA mask. 64bit consistent DMA mask may be set on some 64bit DMA slot, which causes DMA offset "10000000000000" and MFI_INIT and IOCTL frames will have high memory addresses, leads to firmware FAULT.

* [SCSI] Disable WRITE SAME for RAID and virtual host adapter driversMartin K. Petersen2013-11-292-0/+2
| | | | | | | | | | | | | | | | | | Some host adapters do not pass commands through to the target disk directly. Instead they provide an emulated target which may or may not accurately report its capabilities. In some cases the physical device characteristics are reported even when the host adapter is processing commands on the device's behalf. This can lead to adapter firmware hangs or excessive I/O errors. This patch disables WRITE SAME for devices connected to host adapters that provide an emulated target. Driver writers can disable WRITE SAME by setting the no_write_same flag in the host adapter template. [jejb: fix up rejections due to eh_deadline patch] Signed-off-by: Martin K.

* [SCSI] megaraid_sas: Add support for Uneven Span PRL11Sumit.Saxena@lsi.com2013-06-245-50/+904
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MegaRAID older Firmware does not support uneven span configuration for PRL11. E.g User wants to create 34 Driver PRL11 config, it was not possible using old firmware, since it was not supported configuration in old firmware Old Firmware expect even number of Drives in each span and same number of physical drives at each span. Considering above design, 17 Drives at Span-0 and 17 drives at span-1 was not possible. Now, using this new feature Firmware and Driver both required changes. New Firmware can allow user to create 16 Drives at span-0 and 18 Drives at span-1. This will allow user to create 34 Drives Uneven span PRL11. RAID map is interface between Driver and FW to fetch all required fields(attributes) for each Virtual Drives. Since legacy RAID map consider Even Span design, there was no place to keep Uneven span information in existing Raid map. Because of this limitation, for Uneven span VD, driver can not use RAID map. This patch address the changes required in Driver to support Uneven span PRL11 support. 1. Driver will find if Firmware has UnevenSpanSupport or not by reading Controller Info. 2. If Firmware has UnvenSpan PRL11 support, then Driver will inform about its capability of handling UnevenSpan PRL11 to the firmware. 3. Driver will update its copy of span info on each time Raid map update is called. 4. Follow different IO path if it is Uneven Span. (For Uneven Span, Driver uses Span Set info to find relavent fields for that particular Virtual Disk) More verbose prints will be available by setting "SPAN_DEBUG" to 1 at compilation time.

* [SCSI] megaraid_sas: Use correct #define for MSI-X capabilityBjorn Helgaas2013-04-182-5/+2
| | | | | | | | | | | Previously we used PCI_MSI_FLAGS to locate a register in the MSI-X capability. This did work because the MSI and MSI-X flags happen to be at the same offsets, but was confusing. PCI_MSIX_FLAGS_ENABLE is already defined in include/uapi/linux/pci_regs.h, so no need to define it again.

* [SCSI] megaraid_sas: Dont load DevHandle unless FastPath enabledadam radford2013-02-221-1/+2
| | | | | | | | | | | The following patch for megaraid_sas will fix an issue where the driver should not be loading the DevHandle unless FastPath is enabled. If FastPath was not enabled, this means the hardware raid map validation failed for some reason, or the map was corrupted, which could mean the DevHandle could be invalid.

* Drivers: scsi: remove __dev* attributes.Greg Kroah-Hartman2013-01-032-7/+7
| | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* megaraid: fix BUG_ON() from incorrect use of delayed workXiaotian Feng2012-12-042-9/+7
| | | | | | | | | | | | | | | | | | | megaraid use INIT_WORK to declare a hotplug_work, but cast the hotplug_work from work_struct to delayed_work and schedule_delayed_work on it. This is very dangerous, as other part of delayed_work might be kernel memories allocated by others. With commit 8852aac ("workqueue: mod_delayed_work_on() shouldn't queue timer on 0 delay"), schedule_delayed_work() will check dwork->timer before queue_work even when @delay is 0, this causes megaraid code to hit the BUG_ON() in workqueue code. Change megaraid code to use delayed work. Signed-off-by: Xiaotian Feng <dannyfeng@tencent.com> Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Neela Syam Kolli <megaraidlinux@lsi.com> Cc: "James E.J.
