| | | | | | | | | | | | | | | | | | | During EEH recovery number of online CPU's might change thereby changing the number of MSIx vectors. Since each fib is allocated to a vector, changes in the number of vectors causes fib to be sent thru invalid vectors.In addition the correct number of MSIx vectors is not updated in the INIT struct sent to the controller, when it is reinitialized.

* aacraid: Fix RRQ overloadRaghava Aditya Renukunta2016-02-243-23/+37
| | | | | | | | | | | | | | | | | | | | | | | 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.

* aacraid: SCSI blk tag supportRaghava Aditya Renukunta2016-02-245-20/+44
| | | | | | | | | | | | | | | | | | | 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.
