Root cause: When kernel crashes, On brocade 815/825 adapters, bfa IOC state machine and FW doesn't get a notification and hence are not cleanly shutdown. So registers holding driver/IOC state information are not reset back to valid disabled/parking values. This causes subsequent driver initialization to fail during kdump kernel boot. Fix description: during the initialization of first PCI function, reset corresponding register when unclean shutown is detect by reading chip registers. This will make sure that ioc/fw gets clean re-initialization. Signed-off-by:

On Xen kernels, if ATC (address translation cache) is enabled, the first PCIe DMA read from the adapter fails with an error. This is due to a bug ASIC, which leads to a failure of 1860 ports to be initialised. This patch includes the fix to disable Invalidated Tag Match Enable capability by setting the bit 26 of CHIP_MISC_PRG to 0, by default it is set to 1. Signed-off-by:

D-Port is a new port type created with the intention of running link level diagnostic tests like loopback, traffic test. In static D-port mode, user configures the port to D-port mode and starts the test, but in dynamic D-port, once the Brocade switch port is configured to D-port, it will reject the regular FLOGI from HBA with reason that it is in D-port mode. So based on the reason code HBA port will turn itself into D-port and start diagnostic test. Signed-off-by:

The 'ctl' field of the 'struct ata_taskfile' is not really dual purpose, i.e. it is not intended for storing the alternate status register (which is mapped at the same address in the legacy IDE controllers) in the qc_fill_rtf() method. No other 'libata' driver except 'drivers/scsi/ipr.c' stores the alternate status register's value in the 'ctl' field of 'qc->result_tf', hence this driver should not do this as well... Signed-off-by:

Commit 39c60a09 '[SCSI] sd: fix array cache flushing bug causing performance problems' added temp as a pointer to "temporary " and used sizeof(temp) - 1 as its length. But sizeof(temp) is the size of the pointer, not the size of the string constant. Change temp to a static array so that sizeof() does what was intended. Signed-off-by:

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.
