Link start-up requires long time with multiphase handshakes between UFS host and device. This affects driver's probe time. This patch let link start-up run asynchronously. Link start-up will be executed at the end of prove separately. Along with this change, the following is worked. Defined completion time of uic command to avoid a permanent wait. Added mutex to guarantee of uic command at a time. Adapted some sequence of controller initialization after link statup according to HCI standard. Signed-off-by:

The standard scsi timeout is not appropriate in some of the environments where Hyper-V is deployed. Set this timeout appropriately for all devices managed by this driver. On cloud environments where storage latencies may be unbounded, having the scsi layer initiating recovery can be problematic since (a) the host is already implementing a variety of recovery strategies and (b) implementing a recovery strategy at the VM level may be more appropriate in cases where storage latencies exceed a certain threshold.

This is the kernel part of the modification to extract the net params from the ibft sysfs to the iface struct used for the connection request upon sync_session in the open-iscsi util. Three new session sysfs params are defined: boot_root - holds the name of the /sys/firmware/ibft or iscsi_rootN boot_nic - holds the ethernetN name boot_target - holds the targetN name Signed-off-by:

One of the customer had reported that the set of raid logical arrays will become unavailable (I/O offline) after a long hours of IO stress test. The OS wouldn`t be accessible afterwards and require a hard reset. This driver patch has a fix for race condition between the doorbell and the circular buffer. The driver is modified to do an extra read after clearing the doorbell in case there had been a completion posted during the small timing window. With this fix, we ran IO stress for ~13 days. There were no IO failures. Signed-off-by:

SATA drives located behind a SAS controller would incorrectly receive WRITE SAME commands. Tweak the heuristics so that: - If REPORT SUPPORTED OPERATION CODES is provided we will use that to choose between WRITE SAME(16), WRITE SAME(10) and disabled. This also fixes an issue with the old code which would issue WRITE SAME(10) despite the command not being whitelisted in REPORT SUPPORTED OPERATION CODES. - If REPORT SUPPORTED OPERATION CODES is not provided we will fall back to WRITE SAME(10) unless the device has an ATA Information VPD page. The assumption is that a SATL which is smart enough to implement WRITE SAME would also provide REPORT SUPPORTED OPERATION CODES. To facilitate the new heuristics scsi_report_opcode() has been modified to so we can distinguish between "operation not supported" and "RSOC not supported". Reported-by:

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.

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:
