2016-04-29aacraid: Fix for KDUMP driver hangRaghava Aditya Renukunta
When KDUMP is triggered the driver first talks to the firmware in INTX mode, but the adapter firmware is still in MSIX mode. Therefore the first driver command hangs since the driver is waiting for an INTX response and firmware gives a MSIX response. If when the OS is installed on a RAID drive created by the adapter KDUMP will hang since the driver does not receive a response in sync mode. Fixed by: Change the firmware to INTX mode if it is in MSIX mode before sending the first sync command.

2016-02-23aacraid: Fix RRQ overloadRaghava Aditya Renukunta
The driver utilizes an array of atomic variables to keep track of IO submissions to each vector. To submit an IO multiple threads iterate through the array to find a vector which has empty slots to send an IO. The reading and updating of the variable is not atomic, causing race conditions when a thread uses a full vector to submit an IO. Fixed by mapping each FIB to a vector, the submission path then uses said vector to submit IO thereby removing the possibly of a race condition.The vector assignment is started from 1 since vector 0 is reserved for the use of AIF management FIBS.If the number of MSIx vectors is 1 (MSI or INTx mode) then all the fibs are allocated to vector 0.

2016-02-23aacraid: SCSI blk tag supportRaghava Aditya Renukunta
The method to allocate and free FIB's in the present code utilizes spinlocks. Multiple IO's have to wait on the spinlock to acquire or free fibs creating a performance bottleneck. An alternative solution would be to use block layer tags to keep track of the fibs allocated and freed. To this end aac_fib_alloc_tag was created to utilize the blk layer tags to plug into the Fib pool.These functions are used exclusively in the IO path. 8 fibs are reserved for the use of AIF management software and utilize the previous spinlock based implementations.
