aacraid: Fix for KDUMP driver hang

2016-04-29T23:08:24+00:00

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.

aacraid: Fix AIF triggered IOP_RESET

2016-02-24T02:27:02+00:00

while driver removal is in progress or PCI shutdown is invoked, driver
kills AIF aacraid thread, but IOCTL requests from the management tools
re-start AIF thread leading to IOP_RESET.

Fixed by setting adapter_shutdown flag when PCI shutdown is invoked.

aacraid: IOCTL fix

2015-04-09T23:54:40+00:00

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.

This patch fixes the IOP_RESET issue. Sending IOP_RESET command need to wait
for only 10 sec instead of 5 minutes in case of firmware does not response
IOP_RESET command.  Disable interrupt before setup interrupt routine to
prevent spurious interrupts.
