2022-07-14scsi: smartpqi: Add ctrl ready timeout module parameterKevin Barnett1-0/+2
Allow user to override the default driver timeout for controller ready. There are some rare configurations which require the driver to wait longer than the normal 3 minutes for the controller to complete its bootup sequence and be ready to accept commands from the driver. The module parameter is: ctrl_ready_timeout= { 0 | 30-1800 } and specifies the timeout in seconds for the driver to wait for controller ready. The valid range is 0 or 30-1800. The default value is 0, which causes the driver to use a timeout of 180 seconds (3 minutes).

2021-10-05scsi: smartpqi: Add controller handshake during kdumpMahesh Rajashekhara1-0/+1
Correct kdump hangs when controller is locked up. There are occasions when a controller reboot (controller soft reset) is issued when a controller firmware crash dump is in progress. This leads to incomplete controller firmware crash dump: - When the controller crash dump is in progress, and a kdump is initiated, the driver issues inbound doorbell reset to bring back the controller in SIS mode. - If the controller is in locked up state, the inbound doorbell reset does not work causing controller initialization failures. This results in the driver hanging waiting for SIS mode. To avoid an incomplete controller crash dump, add in a controller crash dump handshake: - Controller will indicate start and end of the controller crash dump by setting some register bits. - Driver will look these bits when a kdump is initiated. If a controller crash dump is in progress, the driver will wait for the controller crash dump to complete before issuing the controller soft reset then complete driver initialization.
