2015-05-31hpsa: factor out hpsa_init_cmd functionStephen Cameron
Factor out hpsa_cmd_init from cmd_alloc(). We also need this for resubmitting commands down the default RAID path when they have returned from the ioaccel paths with errors. In particular, reinitialize the cmd_type and busaddr fields as these will not be correct for submitting down the RAID stack path after ioaccel command completion. This saves time when submitting commands.

2015-05-31hpsa: hpsa decode sense data for io and tmfStephen Cameron
In hba mode, we could get sense data in descriptor format so we need to handle that. It's possible for CommandStatus to have value 0x0D "TMF Function Status", which we should handle. We will get this from a P1224 when aborting a non-existent tag, for example. The "ScsiStatus" field of the errinfo field will contain the TMF function status value.

2015-05-31hpsa: clean up abortsStephen Cameron
Do not send aborts to logical devices that do not support aborts Instead of relying on what the Smart Array claims for supporting logical drives, simply try an abort and see how it responds at device discovery time. This way devices that do support aborts (e.g. MSA2000) can work and we do not waste time trying to send aborts to logical drives that do not support them (important for high IOPS devices.) While rescanning devices only test whether devices support aborts the first time we encounter a device rather than every time. Some Smart Arrays required aborts to be sent with tags in the wrong endian byte order. To avoid having to know about this, we would send two aborts with tags with each endian order. On high IOPS devices, this turns out to be not such a hot idea. So we now have a list of the devices that got the tag backwards, and we only send it one way. If all available commands are outstanding and the abort handler is invoked, the abort handler may not be able to allocate a command and may busy-wait excessivly. Reserve a small number of commands for the abort handler and limit the number of concurrent abort requests to the number of reserved commands.

2015-05-31hpsa: rework controller command submissionWebb Scales
Allow driver initiated commands to have a timeout. It does not yet try to do anything with timeouts on such commands. We are sending a reset in order to get rid of a command we want to abort. If we make it return on the same reply queue as the command we want to abort, the completion of the aborted command will not race with the completion of the reset command. Rename hpsa_scsi_do_simple_cmd_core() to hpsa_scsi_do_simple_cmd(), since this function is the interface for issuing commands to the controller and not the "core" of that implementation. Add a parameter to it which allows the caller to specify the reply queue to be used. Modify existing callers to specify the default reply queue. Rename __hpsa_scsi_do_simple_cmd_core() to hpsa_scsi_do_simple_cmd_core(), since this routine is the "core" implementation of the "do simple command" function and there is no longer any other function with a similar name. Modify the existing callers of this routine (other than hpsa_scsi_do_simple_cmd()) to instead call hpsa_scsi_do_simple_cmd(), since it will now accept the reply_queue paramenter, and it provides a controller lock-up check. (Also, tweak two related message strings to make them distinct from each other.) Submitting a command to a locked up controller always results in a timeout, so check for controller lock-up before submitting. This is to enable fixing a race between command completions and abort completions on different reply queues in a subsequent patch. We want to be able to specify which reply queue an abort completion should occur on so that it cannot race the completion of the command it is trying to abort. The following race was possible in theory: 1. Abort command is sent to hardware. 2. Command to be aborted simultaneously completes on another reply queue. 3. Hardware receives abort command, decides command has already completed and indicates this to the driver via another different reply queue. 4. driver processes abort completion finds that the hardware does not know about the command, concludes that therefore the command cannot complete, returns SUCCESS indicating to the mid-layer that the scsi_cmnd may be re-used. 5. Command from step 2 is processed and completed back to scsi mid layer (after we already promised that would never happen.) Fix by forcing aborts to complete on the same reply queue as the command they are aborting. Piggybacking device rescanning functionality onto the lockup detection thread is not a good idea because if the controller locks up during device rescanning, then the thread could get stuck, then the lockup isn't detected. Use separate work queues for device rescanning and lockup detection. Detect controller lockup in abort handler. After a lockup is detected, return DO_NO_CONNECT which results in immediate termination of commands rather than DID_ERR which results in retries. Modify detect_controller_lockup() to return the result, to remove the need for a separate check.

2015-05-31hpsa: add masked physical devices into h->dev[] arrayStephen Cameron
Cache the ioaccel handle so that when we need to abort commands sent down the ioaccel2 path, we can look up the LUN ID in h->dev[] instead of having to do I/O to the controller. Add a field to elements in h->dev[] to keep track of how the device is exposed to the SCSI mid layer: Not at all, without an upper level driver (no_uld_attach) or normally exposed. Since masked physical devices are now present in h->dev[] array it would be perfectly possible to do echo scsi add-single-device 2 2 0 0 > /proc/scsi/scsi and bring them online. This was previously not allowed for masked physical devices. Ensure that the mapping of physical disks to logical drives gets updated in a consistent way when a RAID migration occurs and is not touched until updates to it are complete. now instead of doing CISS_REPORT_PHYSICAL to get the LUNID for the physical disk in hpsa_get_pdisk_of_ioaccel2(), just get it out of h->dev[] where we already have it cached. do not touch phys_disk[] for ioaccel enabled logical drives during rescan Reviewed-by: Scott Teel <scott.teel@pmcs.com> Reviewed-by: Kevin Barnett <kevin.barnett@pmcs.com> Reviewed-by: Tomas Henzl <thenzl@redhat.com> Reviewed-by: Hannes Reinecke <hare@Suse.de> Signed-off-by: Don Brace <don.brace@pmcs.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <JBottomley@Odin.com>
