No restriction should be placed on the IRQ number assigned to a given ISP. Original code incorrectly assumed a non-zero IRQ number assignment by the system. In these circumstances the proper freeing of the IRQ (via free_irq()) would not take place. Signed-off-by:

This patch removes a duplicate device id from the IPR driver. Based on the ipr.h file, I'm not so sure this was intended to be a duplicate, and if so, the .h file should be modified to use the proper sub-device id instead.

Register libsas's default device reset code with the scsi. Signed-off-by:

Darrick J. Wong authored
This patch moves the code that handles SAS failures out of the main EH function and into a separate function. It also detects commands that have no sas_task (i.e. they completed, but with error data) and sends them into scsi_error for processing. This allows us to handle SCSI errors (and enables auto-spinup as a side effect) instead of dropping them on the floor and falling into an infinite loop. It also requires the implementation of a device reset function, which the SAS failure code has been modified to employ for REQ_DEVICE_RESET. Signed-off-by:

sas_rphy_delete does two things: it removes the sas_rphy from the transport layer and frees the sas_rphy. This can be broken down into two functions, sas_rphy_remove and sas_rphy_free; sas_rphy_remove is of interest to sas_discover_root_expander because it calls functions that require sas_rphy_add as a prerequisite and can fail (namely sas_discover_expander). In that case, sas_discover_root_expander needs to be able to undo the effects of sas_rphy_add yet leave the job of freeing the sas_rphy to the caller of sas_discover_root_expander. This patch also removes some unnecessary code from sas_discover_end_dev to eliminate an unnecessary cycle of sas_notify_lldd_gone/found for SAS devices, thus eliminating a sas_rphy_remove call (and fixing a race condition where a SCSI target scan can come in between the gone and found call). It also moves the sas_rphy_free calls into sas_discover_domain and sas_ex_discover_end_dev to complement the sas_rphy_allocation via sas_get_port_device. This patch does not change the semantics of sas_rphy_delete. Signed-off-by:

Currently, sas_form_port checks the given asd_sas_phy's sas_phy to see if there's already a port attached. If so, the SAS addresses of the port and the phy are compared to determine if we need to detach from the port because the addresses don't match or if we can stop; the SAS address stored in the sas_port reflects whatever device _was_ attached to the port/phy, and the SAS address stored in the sas_port reflects whatever device we just discovered. As written, the code detaches from the port if the addresses _do_ match, and prints an error if they do _not_ match. I believe this to be incorrect, as it seems more logical to keep the port if the addresses match (i.e. the phy was reset but the device didn't change), and detach it they do not (i.e. the device changed).

Received from Mark Salyzyn, Take the expose_physicals flag and allow the user to select default (physicals available via /dev/sg), exposed (physicals available via /dev/sd for experimental reasons) and hidden (physicals blocked from all access). This expands the functionality of the previous expose_physicals insmod parameter which was added to support some experimental configurations.

Received from Mark Salyzyn, Replace all if/else communication transports with a platform function call. This is in recognition of the need to migrate to up-and-coming transports. Currently the Linux driver does not support two available communication transports provided by our products, these will be added in future patches, and will expand the platform function set.

Allowing the phy reset controls to be world-triggerable does not seem like a terribly good idea because SAS devices can be disrupted (and ATA devices are really disrupted) by a phy reset. By default only root should be able to do things like that. Signed-off-by:

Extend the use of the DDB lock to include all DDB accesses, because DDB updates now occur from multiple threads. This fixes the SMP timeout problems that we were occasionally seeing with a x260, because the controller got confused when the DDBs got corrupted. Signed-off-by:

Now that task aborts and device port resets are done by the EH, we can remove all the code that set up workqueues and such and simply call sas_task_abort and let libsas figure things out. Signed-off-by: -
Darrick J. Wong authored
sas_task_abort() should simply abort the upper-level SCSI command and wait until the error handler to send the actual ABORT TASK command. By deferring things to the EH we simplify the concurrency coordination and eliminate some race conditions. Note that sas_task_abort has a few hooks to handle libsas internal commands properly too. Also rename do_sas_task_abort to __sas_task_abort just in case we really want to abort the task *right now* and we don't have a scsi_cmnd attached to the command. This is a hook for libata internal commands to abort. Signed-off-by:

When a SAS LLDD needs to request a device port reset, it needs to have all commands aborted before it can reset the port. Since commands are put on the EH's list in the order that they were queued, the LLDD can set a "need reset" flag in the last task to be aborted so that the EH can reset the port after all commands are aborted. Signed-off-by:
-
Darrick J. Wong authored
This flag is no longer necessary because we push tasks to be aborted into the EH as soon as we possibly can, and let the SCSI EH code take care of the coordination for which this flag was used. Signed-off-by:

In this driver, TMF_QUERY_TASK translates to QUERY_SSP_TASK. The sequencer, it seems, is perfectly happy sending us a SSP response, which this function promptly "converts" into TMF_RESP_FUNC_FAILED. This leads to the SAS EH making bad decisions based on bad data, so we should not perform the conversion in this case. Signed-off-by:

The aic94xx module has a parameter that looks like it should set lldd_max_execute_num in the sas_ha, but it never sets this value. Either we should set it or remove the parameter. This allows us to enable task collector mode for this driver, though it is still off by default. Signed-off-by:

Darrick J. Wong authored
If we use task collector mode, we can end up destroying the task collector thread before we release the ports, which is bad if a port release causes a disk I/O (such as cache flushing). Signed-off-by:
