We can just dma map the sense buffer passed with the scsi command, and that gets us out of the nasty business of doing dma coherent allocations from irq context. Signed-off-by:

This also moves the optimization for builds with 32-bit dma_addr_t to the compiler (where it belongs) instead of opencoding it based on incorrect assumptions. Signed-off-by:

CONFIG_HIGHMEM is not in fact an indicator for > 32-bit dma addressing Given that the driver is a bit weird and wants a compile time selection switch to checking CONFIG_ARCH_DMA_ADDR_T_64BIT instead. Signed-off-by:

CONFIG_HIGHMEM64 is only one (and these days unusual) way to indicate that > 32-bit dma address are possible. Replace it with a check of the dma_addr_t size. Signed-off-by:

Add trunking support to the driver. Trunking is found on more recent asics. In general, trunking appears as a single "port" to the driver and overall behavior doesn't differ. Link speed is reported as an aggregate value, while link speed control is done on a per-physical link basis with all links in the trunk symmetrical. Some commands returning port information are updated to additionally provide trunking information. And new ACQEs are generated to report physical link events relative to the trunk. This patch contains the following modifications: - Added link speed settings of 128GB and 256GB. - Added handling of trunk-related ACQEs, mainly logging and trapping of physical link statuses. - Added additional bsg interface to query trunk state by applications. - Augment link_state sysfs attribtute to display trunk link status Signed-off-by:

The switches seem to respond faster to GID_PT vs GID_FT NameServer queries. Add support for GID_PT to be used over GID_FT to enable faster storage failover detection. Includes addition of new module parameter to select between GID_PT and GID_FT (GID_FT is default). Signed-off-by:

An address change for a remote port cause PRLI for the wrong protocol to be sent. The node copy done in the discovery code skipped copying the fc4 protocols supported as well. Fix the copy logic for the address change. Beefed up log messages in this area as well. Signed-off-by:

Testing a point-to-point topology and a case of re-FLOGI without intervening link bouncing, showed an odd interaction with firmware and a resulting scenario where the driver no longer probed after accepting the new FLOGI. Work around the firmware issue by issuing a link bounce if a FLOGI is received after the link is already up and FLOGI's accepted. While debugging the issue, realized that some debug traces should be clarified to help in the future. 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: -

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:
