When LCB's are rejected, if beaconing was already in progress, the Reason Code Explanation was not being set. Should have been set to command in progress. Signed-off-by:

On FCoE adapters, when running link bounce test in a loop, initiator failed to login with switch switch and required driver reload to recover. Switch reached a point where all subsequent FLOGIs would be LS_RJT'd. Further testing showed the condition to be related to not performing FCF discovery between FLOGI's. Fix by monitoring FLOGI failures and once a repeated error is seen repeat FCF discovery. Signed-off-by:

This patch corrects two issues: - An oops would occur if reading based on a non-zero offset. Offset calculation was incorrect. - Updates to ras config (logging level) were ignored if change was made while fw logging was enabled. Revise to dynamically update. Signed-off-by:

Currently, PLOGI failures are infinitely delayed/retried. There have been some fabric situations where the PLOGI's were to the nameserver and it stopped responding. The retries would never clear up. A better resolution in this situation is to retry a couple of times, then drop the link and reinit. This brings back connectivity to the nameserver. Signed-off-by:

After a LOGO in response to an ABTS timeout, a PLOGI wasn't issued to re-establish the login. An nlp_type check in the LOGO completion handler failed to restart discovery for NVME targets. Revised the nlp_type check for NVME as well as SCSI. While reviewing the LOGO handling a few other issues were seen and were addressed: - Better lock synchronization around ndlp data types - When the ABTS times out, unregister the RPI before sending the LOGO so that all local exchange contexts are cleared and nothing received while awaiting LOGO/PLOGI handling will be accepted. - LOGO handling optimized to: Wait only R_A_TOV for a response. It doesn't need to be retried on timeout. If there wasn't a response, a PLOGI will be sent, thus an implicit logout applies as well when the other port sees it. If there is a response, any kind of response is considered "good" and the XRI quarantined for a exchange qualifier window. - PLOGI is issued as soon a LOGO state is resolved. Signed-off-by: -

An error is an error - but not to the existing return value check. Revise check to handle any failure, not just EIO. Signed-off-by:

Supported speeds is not updated when SFP is removed or replaced Supported speed is obtained from lmt field in READ_CONFIG mailbox response. Driver updates supported speeds only once from PCI probe path. After that it is never updated. So, supported speeds remains the same till reboot or driver reload. When SFP is removed or inserted, driver gets SLI-Port Event ACQE. If SFP is removed, lmt wil have value 0. If a different SFP is inserted, lmt will have value according to its supported speeds. So, afterr SLI-Port Event ACQE handling path, send READ_CONFIG mailbox and update supported speeds. If READ_CONFIG fails, set supported speeds to unknown and log. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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().
