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:

1. While FRU VPD data update, inform firmware to send a completion event on I2C bus. Without this change, firmware used to send completion message on I2C bus for every chunk of FRU VPD update. 2. Support for FRU VPN update on CHINOOK2 cards. 3. Append port count to the model name to differentiate between single port and dual port model of 1860. 4. Update the size of the model name to 16bytes Signed-off-by:

Replaced usage of void * with u64 in data structure shared between brocade user space libraries and the bfa driver to address pointer size changes across 32-bit vs 64-bit to have the compatibility between 32bit library and 64bit driver and vice versa. Signed-off-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. 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:
