If the board ID lookup function fails, return the return code rather than return -ENODEV. The only board ID failure reason right now is -ENODEV, so this just provides more informative prints in kdump and adapts to future changes. Tested with error injection while booting with reset_devices on the kernel command line: [ 62.804324] injecting error in inj_hpsa_lookup_board_id: 1 11 [ 62.804423] hpsa 0000:04:00.0: Board ID not found (the pci probe layer does not print an additional message if -ENODEV is the reason) Reviewed-by:

In MSI and MSI-X mode, where hpsa asks for more than one interrupt, hpsa_request_irqs forgets if the first request_irq call failed if later ones succeed. It needs to exit the loop on any failure rather than continue, freeing all irqs that were requested until that point. Also, it needs to clear out the q numbers up to MAX_REPLY_QUEUES. The same is true for the general hpsa_free_irqs function. Tested with error injection of -ENOSYS on the 4th call: [ 9.277691] injecting error in inj_request_irq: 1 4 [ 9.277780] hpsa 0000:02:00.0: failed to get irq 35 for hpsa1 [ 10.711623] scsi host1: Error handler scsi_eh_1 exiting [ 10.739170] hpsa: probe of 0000:02:00.0 failed with error -38 Reviewed-by:

HP now uses RAID-6 rather than RAID-ADG (Advanced Data Guarding) as the marketing name for our implementation of RAID-6. The driver considers RAID-1 and RAID-1+0 to be the same level, and considers RAID-1ADM and RAID-1+0ADM to be the same level. Parenthesis can be used to reflect the optional +0 portion of both those RAID levels. Rename: RAID-ADG to RAID-6 RAID-1(1+0) to RAID-1(+0) RAID-1(ADM) to RAID-1(+0)ADM Also, add another const after the pointer type as suggested by checkpatch.pl so the array is: static const char * const raid_label[] Reviewed-by:

Change how SA controllers are reset by changing PCI power levels. The hpsa driver was finding the PCI_PM_CTRL_STATE_MASK offset then reading/writing a bitmask to change the power state. There are kernel functions that do the same operations. Better to use the kernel functions. Signed-off-by:

Sometimes when the card is restarted it may cause - "irq 16: nobody cared (try booting with the "irqpoll" option)" that is likely caused so, that the card, after the hard reset finishes, pulls on the irq. Disabling the ints before or after the hpsa_kdump_hard_reset_controller fixes it. At this point we can't know in which state the card is, so using SA5_INTR_OFF + SA5_REPLY_INTR_MASK_OFFSET defines directly, instead of the function the drivers provides, seems to be apropriate.

Added a support to set cpu affinity mask for each MSIX vector enabled by the HBA. So that, running the irqbalancer will balance interrupts among the cpus. Change_set: 1. Added affinity_hint varable of type cpumask_var_t in adapter_reply_queue structure. And allocated a memory for this varable by calling alloc_cpumask_var. 2. Call the API irq_set_affinity_hint for each MSIx vector to affiniate it with calculated cpus at driver inilization time. 3. While freeing the MSIX vector, call this same API to release the cpu affinity mask for each MSIx vector by providing the NULL value in cpumask argument. 4. then call the free_cpumask_var API to free the memory allocated in step 2.

For any SCSI command, if the driver receives IOC status = SCSI_IOC_TERMINATED and log info = 0x32010081 then that command will be completed with DID_RESET host status. The definition of this log info value is "Virtual IO has failed and has to be retried". Firmware will provide this log info value with IOC Status "SCSI_IOC_TERMINATED", whenever a drive (with is a part of a volume) is pulled and pushed back within some minimal delay. With this log info value, firmware informs the driver to retry the failed IO command infinite times, so to provide some time for the firmware to discover the reinserted drive successfully instated of just retrying failed command for five times( doesn't giving enough time for firmware to complete the drive discovery) and failing the IO permanently even though drive came back successfully.

Change Set: 1. Extended the upper boundary restriction for the module parameter max_sgl_entries. Earlier, the max_sgl_entries was capped at the SCSI_MAX_SG_SEGMENTS kernel definition. With this change, the user would be able to set the max_sgl_entries to any value which is greater than SCSI_MAX_SG_SEGMENTS and less than the minimum of SCSI_MAX_SG_CHAIN_SEGMENTS & hardware limit (Calculated using IOCFacts's MaxChainDepth). 2. Added a print for the message log whenever the user sets the max_sgl_entries to a value greater than SCSI_MAX_SG_SEGMENTS to warn about the kernel definition overriding. Signed-off-by:

mpt2sas, mpt3sas: Fail the host reset initiated due to discovery related I/O timeouts at driver load time When a flaky disk is there in a topology then during driver load, discovery related I/O times out; which results in SCSI error recovery initiating host reset and then the controller won't see any disk. In this patch, The driver would return FAILED status to the host reset initiated due to discovery related I/O timeout if ioc->is_driver_loading is set. This flag would be set until we exit out of scsih_scan_finished(). i.e. During device discovery if one of the disk is flaky (which responds to some discovery commands and doesn't respond to some) the driver wouldn't perform host reset for discovery related I/O timeout. Instead it would return Failure for the host reset resulting in the flaky disk getting removed by the SCSI Mid layer, so other disks would be added correctly. Signed-off-by:

This patch will log a message when driver receives "Temperature Threshold exceeded" event from any temperature sensor. The message will look similar to like: mpt3sas0: Temperature Threshold flags a b c d exceeded for Sensor: x !!! mpt3sas0: Current Temp In Celsius: y where a b c d are threshold flags 0 1 2 3 Change_set: 1. Get the number of sensor count of this IOC by reading IO Unit page 8 at driver initialization time. 2. Also unmask the Temperature Threshold Event at driver initialization time 3. Whenever a MPI2_EVENT_TEMP_THRESHOLD event is received from the firmware, then print the sensor number, the maximum threshold number it has exceed and the current temperature of this sensor.

1) For fusion adapters, limit reserved frames for non SCSI commands to 8 (3 for parallel IOCTLs + 5 for driver's internal DCMDs). Earlier reserved commands for non SCSI IO frames was set to 32, so with this implementation, increased per controller "can_queue". Behavior of MFI controllers will remain unchanged. 2) Optimize the code related to per controller's 'can_queue' setting. Signed-off-by:

Driver calls megasas_complete_cmd() to call wake_up() for each MFI frame that was issued through the ioctl() interface prior to the kill adapter. This ensures userspace ioctl() system calls issued just before a kill adapter don't get stuck in wait state and IOCTLs are returned to the application. Cc: <stable@vger.kernel.org> Signed-off-by:

This patch will address the issue of SCSI device created at OS level for non existing VD. ldTgtIdtoLd[] array has size 256 for Extended VD firmware and 128 for legacy firmware. Accessing indices beyond array size (OS will send TUR, INQUIRY.. commands upto device index 255), may return valid LD value and that particular SCSI command will be SUCCESS and creating SCSI device for non existing target(VD). For legacy firmware (64 VD firmware), invalidates LD (by setting LD value to 0xff) in LdTgtIdtoLd[] array for device index beyond 127, so that invalid LD(0xff) value should be returned beyond device index beyond 127.

It is not good practice to display the kernel pointer in any message logs, and it doesn't display any additional information. And as we know have block-layer assigned tags we can use them to differentiate the messages. So remove any pointer references from the displayed messages. Signed-off-by:
