[PATCH 02/22] [SCSI] mpt2sas, mpt3sas: Added support to log message when Temperature Threshold exceeds for any Sensor

[Sreekanth Reddy]

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.

Re: [PATCH 02/22] [SCSI] mpt2sas, mpt3sas: Added support to log message when Temperature Threshold exceeds for any Sensor

Sreekanth> where a b c d are threshold flags 0 1 2 3

Changes look fine. However, I'm a bit concerned about the unbounded
nature of this. What prevents the log from being flooded with
temperature warnings?

[PATCH 03/22] [PATCH] mpt2sas, mpt3sas: Fail the host reset initiated due to discovery related I/O timeouts at driver load time

[Sreekanth Reddy]

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.

[PATCH 06/22] [SCSI] mpt2sas, mpt3sas: Removing uppper boundary restriction for the module parameter max_sgl_entries

[Sreekanth Reddy]

1. Removed 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.
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.

Shouldn't you be capping at SCSI_MAX_SG_CHAIN_SEGMENTS (or the actual hw

The meaning 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 with 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.

Regards,
Sreekanth.

[PATCH 09/22] [SCSI] mpt2sas, mpt3sas: Added a support to set cpu affinity for each MSIX vector enabled by the HBA

[Sreekanth Reddy]

Added a support to set cpu affinity mask for each MSIX vector enabled by the HBA,
So that by runnig the irqbalancer, interrupts can be balanced among the cpus.

Change_set:
1. Call the API irq_set_affinity_hint for each MSIX vector to affiniate it with avalibale online cpus at driver inilization time.
2. At the driver unload time, call this same API to release the cpu affinity mask for each MSIx vector by providing the NULL value in cpumask argument.

Wouldn't it be better to do this in _base_assign_reply_queues since
we're already iterating there?

[PATCH 11/22] [SCSI] mpt3sas: Added Combined Reply Queue feature to extend up-to 96 MSIX vector support

[Sreekanth Reddy]

In this patch, increased the number of MSIX vector support for SAS3 C0 HBAs to up-to 96.

Following are changes that are done in this patch
1. Support this feature only for SAS3 C0 cards and also only when reply post free queue count is greater than 8.
2. Instead of using single ReplyPostHostIndex system interface, here 12 ReplyPostHostIndex system interfaces are used. reply post free queues numbered from 0 to 7 use the first ReplyPostHostIndex system interface to update its corresponding ReplyPostHostIndex values, reply post free queues numbered from 8 to 15 will use the second ReplyPostHostIndex system interface and so on. These 12 ReplyPostHostIndex system interfaces address are saved in the array replyPostRegisterIndex[].
3. Update the ReplyPostHostIndex value of corresponding reply post free queue in the (its msix_index/8)th entry of replyPostRegisterIndex[] array after processing the reply post descriptor.

Driver initialization fails if driver tries to send IOC facts request message when the IOC is in reset or in a fault state.

This patch will make sure that
 1.Driver to send IOC facts request message only if HBA is in operational or ready state.
 2.If IOC is in fault state, a diagnostic reset would be issued.
 3.If IOC is in reset state then driver will wait for 10 seconds to exit out of reset state.
   If the HBA continues to be in reset state, then the HBA wouldn't be claimed by the driver.

[PATCH 13/22] [SCSI] mpt3sas: Added module parameter 'unblock_io' to unblock IO's during disk addition

[Sreekanth Reddy]

During hot-plugging of a disk(having a flaky link), the disk addition
stops and any further disk addition or removal doesn't happen on that controller.

This is because, when driver receives DELAY_NOT_RESPONDING for a disk when it is undergoing
addition in the SCSI Mid layer, the driver would block the I/O to that disk
resulting in a deadlock. i.e the disk addition work couldn't be completed
as it can't send any I/O to the disk as I/Os are blocked. Any device removal (TARGET_NOT_RESPONDING)
or link update(RC_PHY_CHANGED) couldn't be processed as they are in the queue
to get processed after disk addition.

Description of Change:
To handle such cases, unblock the I/Os to the disk in ISR context if the disk is undergoing
addition. The I/Os would get unblocked only if the driver receives RC_PHY_CHANGED reason
code when the device addition is within the SAS Transport layer.

An module parameter 'unblock_io' is introduced which needs to be set to have this
functionality enabled. By default this functionality is disabled.

[PATCH 16/22] [SCSI] mpt3sas: Provides the physical location of sas drives

[Sreekanth Reddy]

This Patch will provide more details of the devices such as slot number, enclosure logical id, enclosure level & connector name in the following scenarios,

- When end device is added in the topology,
- When the end device is removed from the setup,
- When the SCSI mid layer issues TASK ABORT/ DEVICE RESET/ TARGET RESET during error handling,
- When any command to the device fails with Sense key Hardware error or Medium error or Unit Attention,
- When firmware returns device error or device not ready status for the end device,
- When a Predicted fault is detected on an end device.

This information can be used by the user to identify the location of the desired drive in the topology.

Driver will get these information by reading the sas device page0.

RE: [PATCH 06/22] [SCSI] mpt2sas, mpt3sas: Removing uppper boundary restriction for the module parameter max_sgl_entries

[Sreekanth Reddy]

> Shouldn't you be capping at SCSI_MAX_SG_CHAIN_SEGMENTS (or the actual hw
> limit)?

Agreed. And set the Upper limit to SCSI_MAX_SG_CHAIN_SEGMENTS.

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.

Wouldn't it be better to print the new scatterlist limit after it has
been clamped to reflect what it's actually being set to?

but Martin, I though to warn the user that the module parameter
max_sgl_entries value what they provided is greater than the kernel
defined SCSI_MAX_SG_SEGMENTS, whether if this module parameter value
is greater than or less than the SCSI_MAX_SG_CHAIN_SEGMENTS. Also I
thought, user may confuse if see observes SCSI_MAX_SG_CHAIN_SEGMENTS
value instead of max_sgl_entries value in the warning message.

Please let me known If my assumption is wrong. Then I will modify this
patch according to your suggestion i.e I will print the scatterlist
limit after it has been clamped.

Thanks,
Sreekanth

I would just prefer to see the value that is in effect. I know what I
provided as override value.

At the very least print a warning if you subsequently clamp the value to
MAX_SG_CHAIN_SEGMENTS. "Requested number of segments %u is bigger than
kernel max %u".

Hi Martin,

As per your suggestion I have modified the Warning message. Please review the change.
 
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.
