The print related to number of VDs that a particular firmware supports is misleading in some cases. Even though supportMaxExtLDs is set, certain firmware profiles only supports upto 64VDs.

For SAS3 and later controllers, FW sets the reset adapter bit indicating the driver to perform a controller reset. Driver needs to check if this bit is set before doing a reset. This reduces the driver probe failure time to 180seconds in case there is a faulty controller connected.

In megasas_transition_to_ready() driver waits 180seconds for controller to change FW state. Here we are calling msleep(1) in a loop for this. As explained in timers-howto.txt, msleep(1) will actually sleep longer than 1ms. If a faulty controller is connected, we will end up waiting for much more than 180 seconds causing unnecessary delays during load. Change the granularity of msleep() call from 1ms to 1000ms.

Latest firmware adds a mechanism to save firmware logs just before controller reset on pre-allocated internal controller DRAM. This feature is called snapdump which will help debugging firmware issues. This feature requires extra time and firmware reports these values through new driver interface. Before initiating an OCR, driver needs to inform FW to save a snapdump and then wait for a specified time for the snapdump to complete.

Currently driver checks for Firmware state change from ISR context, and only when there are interrupts tied with no I/O completions. We have seen multiple cases where doorbell interrupts sent by firmware to indicate FW state change are not processed by driver and it takes long time for driver to trigger OCR. And if there are no IOs running, since we only check the FW state as part of ISR code, fault goes undetected by driver and OCR will not be triggered. This patch introduces a separate workqueue that runs every one second to detect Firmware FAULT state and trigger reset immediately. As an additional gain, removing PCI reads from ISR to check FW state results in improved performance as well.

This is to fix SYNC CACHE and START STOP command failures with DID_NO_CONNECT during driver unload. In driver's IO submission patch (i.e. in driver's .queuecommand()) driver won't allow any SCSI commands to the IOC when ioc->remove_host flag is set and hence SYNC CACHE commands which are issued to the target drives (where write cache is enabled) during driver unload time is failed with DID_NO_CONNECT status. Now modified the driver to allow SYNC CACHE and START STOP commands to IOC, even when remove_host flag is set.

Call sas_remove_host() before removing the target devices in the driver's .remove() callback function(i.e. during driver unload time). So that driver can provide a way to allow SYNC CACHE, START STOP unit commands etc. (which are issued from SML) to the target drives during driver unload time. Once sas_remove_host() is called before removing the target drives then driver can just clean up the resources allocated for target devices and no need to call sas_port_delete_phy(), sas_port_delete() API's as these API's internally called from sas_remove_host().
