The queue-depth for libsas-attached devices initializes to 32 and can only be increased manually via sysfs to a max of 64, while mpt2sas attached devices initialize to 254 and dynamically float via the midlayer ->change_queue_depth interface. No performance regression was observed with this change on the isci driver.

Pass queue_depth change requests to libata, and prevent queue_type changes for ATA devices. Otherwise: 1/ we do not honor the libata specific restrictions on the queue depth 2/ libsas drivers that do not set sdev->tagged_supported are unable to change the queue_depth of ata devices via sysfs Signed-off-by: NDan Williams <dan.j.williams@intel.com> Acked-by: NJeff Garzik <jgarzik@redhat.com> Signed-off-by: NJames Bottomley <JBottomley@Parallels.com>

Currently mvsas and pm8001 have custom ->slave_alloc implementations to achieve this. Uplevel it for all libsas drivers as isci encounters problems with atapi devices when scanning past lun0. Just do what Darrick suggested [1], and limit the scan for ata devices.

When the ipr driver decides to dump the adapter, it changes the sdt_state to GET_DUMP, then prepares the adapter so that the dump can be read. However, if the ipr worker thread wakes up for some reason before the driver has put the adapter in a state where it can succesfully dump the adapter, the driver will start dumping the adapter too early, which can potentially trigger a BUG check in the pci config blocking API. Fix this by adding a new sdt_state to differentiate between the ipr driver wanting to dump the adapter in the near future and wanting to dump the adapter now.

Support added for controllers capable of multi reply queues. The following are the modifications to the driver to support NUMA. 1) Create the new structure adapter_reply_queue to contain the reply queue info for every msix vector. This object will contain a reply_post_host_index, reply_post_free for each instance, msix_index, among other parameters. We will track all the reply queues on a link list called ioc->reply_queue_list. Each reply queue is aligned with each IRQ, and is passed to the interrupt via the bus_id parameter. (2) The driver will figure out the msix_vector_count from the PCIe MSIX capabilities register instead of the IOC Facts->MaxMSIxVectors. This is because the firmware is not filling in this field until the driver has already registered MSIX support. (3) If the ioc_facts reports that the controller is MSIX compatible in the capabilities, then the driver will request for multiple irqs. This count is calculated based on the minimum between the online cpus available and the ioc->msix_vector_count. This count is reported to firmware in the ioc_init request. (4) New routines were added _base_free_irq and _base_request_irq, so registering and freeing msix vectors were done thru simple function API. (5) The new routine _base_assign_reply_queues was added to align the msix indexes across cpus. This will initialize the array called ioc->cpu_msix_table. This array is looked up on every MPI request so the MSIxIndex is set appropriately. (6) A new shost sysfs attribute was added to report the reply_queue_count. (7) User needs to set the affinity cpu mask, so the interrupts occur on the same cpu that sent the original request.

Basic support to initialize the gpio unit, accept an incomming SAS_GPIO_REG_TX_GP bitstream, and translate it to the ODx.n fields in the hardware registers. If register indexes outside the supported range are specified in the SMP frame we simply accept the write and return how many registers (SFF-8485) were written (libsas reports this as residue in the request).

Add SFF-8485 v0.7 / SAS-1 smp-write-gpio register support to libsas. Defer SAS-2 support unless/until it defines an sgpio interface. Minimum implementation needed to get the lights blinking. try_test_sas_gpio_gp_bit() provides a common method to parse the incoming write data (raw bitstream), and the to_sas_gpio_gp_bit() helper routine can be used as a basis for the set/clear operations for the 'read' implementation. Host implementations parse as many bits (ODx.[012]) as are locally supported and report the number of registers successfully written. If the submitted data overruns the internal number of registers available report the write as a success with the number of bytes remaining reported in ->resid_len. Example (assuming an active backplane) set the "identify" pattern for the first 21 devices: smp_write_gpio --count=2 --data=92,49,24,92,24,92,49,24 -t 4 --index=1 /dev/bsg/sas_hostX Signed-off-by: NDan Williams <dan.j.williams@intel.com> Signed-off-by: NJames Bottomley <JBottomley@Parallels.com>

For Target Portal Group IDs occupying the full 2 bytes in the RTPG response, the following group_id check in the alua_rtpg routine always fails in scsi_dh_alua.c: if (h->group_id == (ucp[2] << 8) + ucp[3]) { This causes the ALUA handler to wrongly identify the AAS of a specified device as well as incorrectly interpreting the supported AAS of the target as seen by the following entries in the /var/log/messages: "alua: port group 3ea state A supports tousna" "alua: port group 3e9 state A supports tousna" This is because 'ucp' is wrongly declared in alua_rtpg as a character pointer instead of an unsigned character pointer.

->queuecommand must return either 0, or one of the SCSI_MLQUEUE_* return values. Non-transient errors are indicated by setting cmd->result before calling ->scsi_done and returning 0. Fix libsas to adhere to this calling convention. Note that the DID_ERROR for returns from the low-level driver might not be correct for all cases, but it's the best we can do with the current layering in libsas. I also suspect that the pre-existing handling of -SAS_QUEUE_FULL should really be SCSI_MLQUEUE_HOST_BUSY, but I'll leave that for a separate change.
