Only SRC-based adapters support the AifReqEvent function, so there is no point in trying to activate it on older, non-SRC based adapters. Doing so lead to crashes on older adapters. Signed-off-by:

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. Cc: stable@vger.kernel.org Signed-off-by:

During EEH PCI hotplug activity kernel unloads and loads the driver, causing character device to be unregistered(aac_remove_one).When the driver is loaded back using aac_probe_one the character device needs to be registered again for the AIF management tools to work. Fixed by adding code to register character device in aac_probe_one if it is unregistered in aac_remove_one. Signed-off-by:

aac_mutex was used to create protect the ioctl path for only the compat path, it would be make more sense to place mutex in aac_do_ioctl, which is the main ioctl function call that handles all ioctl commands. Created new mutex ioctl_mutex in struct aac_dev to protect switch case in aac_do_ioctl and removed aac_mutex from aac_cfg_ioctl and aac_compat_do_ioctl Signed-off-by:

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. Fixes: 495c0217 "aacraid: MSI-x support" Cc: stable@vger.kernel.org # v4.1 Signed-off-by:

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.

After getting the platform shutdown command "VM_CloseAll" response from the firmware, driver was getting configuration IOCTL request from the upper layers and it sends down to firmware. This causes firmware assert issue. This patch fixes the firmware assert issue. During the shutdown, if driver gets commands from the upper layer, driver sends error code to the upper layers.
