2021-02-09scsi: mpt3sas: Add support for shared host tagset for CPU hotplugSreekanth Reddy3-18/+75
MPT Fusion adapters can steer completions to individual queues and we now have support for shared host-wide tags in the I/O stack. The addition of the host-wide tags allows us to enable multiqueue support for MPT Fusion adapters. Once host-wise tags are enabled, the CPU hotplug feature is also supported. Allow use of host-wide tags to be disabled through the "host_tagset_enable" module parameter. Once we do not have any major performance regressions using host-wide tags, we will drop the hand-crafted interrupt affinity settings. Performance is meeting expectations. About 3.1M IOPS using 24 Drive SSD on Aero controllers.

2021-02-09scsi: mpt3sas: Fix ReplyPostFree pool allocationSreekanth Reddy1-1/+2
Currently the driver allocates memory for ReplyPostFree queues in chunks of 16. In resource constrained environments--such as VM with 1 GB RAM and 2 CPUs--memory allocation for ReplyPostFree pools may fail because the driver tries to allocate a memory for 16 ReplyPostFree queues even though the actual number needed is 2. Change the driver to allocate memory for only the actual number of queues needed if the ReplyPostFree queue count is less than 16.

2020-12-09scsi: mpt3sas: Add persistent trigger pages supportSuganath Prabu S4-0/+303
The user can set trigger values in order to collect the IOC's host trace buffer automatically upon detecting certain conditions. However, the trigger values that the user sets are not persistent across system reboot or reload of the driver. In order to make the user trigger settings persistent, these trigger values need to be saved in the IOC's NVRAM pages: - Driver Persistent Trigger Page 0: This page is used to store list of trigger types that are enabled - Driver Persistent Trigger Page 1: This page stores the list of Master triggers that are enabled - Driver Persistent Trigger Page 2: This page stores the list of MPI Event Triggers that are enabled - Driver Persistent Trigger Page 3: This page stores the list of SCSI Sense Triggers that are enabled - Driver Persistent Trigger Page 4: This page stores the list of IOCStatus-LogInfo Triggers that are enabled. Whenever user configures triggers, the driver persists the values in the corresponding trigger pages. When the driver is subsequently reloaded, the driver reads the values from the trigger pages and configures the triggers accordingly. During firmware upload operation, if the newer firmware supports the trigger page feature, then driver persists the configured diag trigger values to NVRAM.

2020-12-09scsi: mpt3sas: Sync time periodically between driver and firmwareSuganath Prabu S2-3/+104
The controller time currently gets updated with host time during driver load or when a controller reset is issued. I.e. when host issues the IOCInit request message to the HBA firmware. This IOCInit message has a field named 'TimeStamp' with which the host updates the controller time. Sometimes controller time drifts with respect to the host and it is difficult to correlate host logs with controller logs. Issuing a controller reset to sync the time would impact in-flight I/O and is not a viable option. Instead the driver now sends an IO_UNIT_CONTROL Request to sync the time periodically. This is done from the watchdog thread which gets invoked every second. The time synchronization interval is specified in the 'TimeSyncInterval' field in Manufacturing Page11 by the controller: TimeSyncInterval - 8 bits bits 0-6: Time stamp Synchronization interval value bit 7: Time stamp Synchronization interval unit, (if this bit is one then Timestamp Synchronization interval value is specified in terms of hours else Timestamp Synchronization interval value is specified in terms of minutes). The driver keeps track of the timer using IOC's timestamp_update_count field. This field value gets incremented whenever the watchdog thread gets invoked. And whenever this field value is greater than or equal to the Time Stamp Synchronization interval value, the driver sends the IO_UNIT_CONTROL Request message to controller to update the time and then it resets the timestamp_update_count field to zero.

2020-12-01scsi: mpt3sas: Remove in_interrupt()Ahmed S. Darwish1-1/+3
_scsih_fw_event_cleanup_queue() waits for all outstanding firmware events wokrqueue handlers to finish. If in_interrupt() is true, it cancels itself and return early. That in_interrupt() check is ill-defined and does not provide what the name suggests: it does not cover all states in which it is safe to block and call functions like cancel_work_sync(). That check is also not needed: _scsih_fw_event_cleanup_queue() is always invoked from process context. Below is an analysis of its callers: - scsih_remove(), bound to PCI ->remove(), process context - scsih_shutdown(), bound to PCI ->shutdown(), process context - mpt3sas_scsih_clear_outstanding_scsi_tm_commands(), called by => _base_clear_outstanding_commands(), called by =>_base_fault_reset_work(), workqueue => mpt3sas_base_hard_reset_handler(), locks mutex Remove the in_interrupt() check.

2020-11-26scsi: mpt3sas_scsih: Use generic power managementVaibhav Gupta1-21/+13
Drivers should do only device-specific jobs. But in general, drivers using legacy PCI PM framework for .suspend()/.resume() have to manage many PCI PM-related tasks themselves which can be done by PCI Core itself. This brings extra load on the driver and it directly calls PCI helper functions to handle them. Switch to the new generic framework by updating function signatures and define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove unnecessary calls to the PCI Helper functions along with the legacy .suspend & .resume bindings.

2020-11-05scsi: mpt3sas: Handle vSES vphy object during HBA resetSreekanth Reddy1-0/+233
During HBA reset the Port ID of vSES device may change. As a result, it is necessary to refresh virtual_phy objects after reset. Each Port's vphy_list table needs to be updated after updating the HBA port table. The algorithm is as follows: - Loop over each port entry from HBA port table * Loop over each virtual phy entry from port's vphys_list table - Mark virtual phy entry as dirty by setting dirty bit in virtual phy entry's flags field - Read SASIOUnitPage0 page - Loop over each HBA Phy's Phy data from SASIOUnitPage0 * If phy's remote attached device is not SES device then continue with processing next HBA Phy's Phy data; * Read SASPhyPage0 data for this Phy number and determine whether current phy is a virtual phy or not. If it is not a virtual phy then continue with next Phy data; * Get the current phy's remote attached vSES device's SAS Address; * Loop over each port entry from HBA port table - If Port's vphys_mask field is zero then continue with next Port entry, - Loop over each virtual phy entry from Port's vphy_list table - If the current phy's remote SAS Address is different from virtual phy entry's SAS Address then continue with next virtual phy entry, - Set bit corresponding to current phy number in virtual phy entry's phy_mask field, - Get the HBA port table's Port entry corresponding to Phy data's 'Port' value, * If there is no Port entry corresponding to Phy data's 'Port' value in HBA port table then create a new port entry and add it to HBA port table. - If this retrieved Port entry is the same as the current Port entry then don't do anything, just clear the dirty bit from virtual phy entry's flag field and continue with processing next HBA Phy's Phy data. - If this retrieved Port entry is different from the current Port entry then move the current virtual phy entry from current Port's vphys_list to retrieved Port entry's vphys_list. * Clear current phy bit in current Port entry's vphys_mask and set the current phy bit in the retrieved Port entry's vphys_mask field. * Clear the dirty bit from virtual phy entry's flag field and continue with next HBA Phy's Phy data. - Delete the 'virtual phy' entries and HBA's 'Port table' entries which are still marked as 'dirty'.

2020-11-05scsi: mpt3sas: Handling HBA vSES deviceSreekanth Reddy3-11/+198
Each direct attached device will have a unique Port ID, but with an exception. HBA vSES may use the same Port ID of another direct attached device Port's ID. As a result, special handling is needed for vSES. Create a virtual_phy object when a new HBA vSES device is detected and add this virtual_phy object to vphys_list of port ID's hba_port object. When the HBA vSES device is removed then remove the corresponding virtual_phy object from its parent's hba_port's vphy_list and free this virtual_vphy object. In hba_port object add vphy_mask field to hold the list of HBA phy bits which are assigned to vSES devices. Also add vphy_list list to hold list of virtual_phy objects which holds the same portID of current hba_port's portID. Also, add a hba_vphy field in _sas_phy object to determine whether this _sas_phy object belongs to vSES device or not. - Allocate a virtual_phy object whenever a virtual phy is detected while processing the SASIOUnitPage0's phy data. And this allocated virtual_phy object to corresponding PortID's hba_port's vphy_list. - When a vSES device is added to the SML then initialize the corresponding virtual_phy objects's sas_address field with vSES device's SAS Address. - Free this virtual_phy object during driver unload time and when this vSES device is removed.

2020-11-05scsi: mpt3sas: Update hba_port objects after host resetSreekanth Reddy1-0/+338
During host reset there is a chance that the Port number allocated by the firmware for the attached devices may change. Also, it may be possible that some HBA phy's can go down/come up after reset. As a result, the driver can't just trust the HBA Port table that it has populated before host reset as valid. Instead it has to update the HBA Port table in such a way that it shouldn't disturb the drives which are still accessible even after host reset. Use the following algorithm to update the HBA Port table during host reset: I. After host reset operation and before marking the devices as responding/non-responding, create a temporary Port table called "New Port table" by parsing each of the HBA phy's Phy data info read from SAS IOUnit Page0: a. Check whether Phy's negotiated link rate is greater than 1.5Gbps, if not go to next Phy; b. Get the SAS Address of the attached device; c. Create a new entry in the "New Port table" with SAS Address field filled with attached device's SAS Address, port number with Phy's Port number (read from SAS IOUnit Page0) and enable bit in the 'Phy mask' field corresponding to current Phy number. New entry is created only if the driver can't find an entry in the "New Port table" which matches with attached device 'SAS Address' & 'Port Number'. If it finds an entry with matches with attached device 'SAS Address' & 'Port Number' then the driver takes that matched entry and will enable current Phy number bit in the 'Phy mask' field; d. After parsing all the HBA phy's info, the driver will have complete Port table info in "New Port table". II. Mark all the existing sas_device & sas_expander device structures as 'dirty'. III. Mark each entry of the HBA Port lists as 'dirty'. IV. Take each entry from 'New Port table' one by one and check whether the entry has any corresponding matched entry (which is marked as 'dirty') in the HBA Port table or not. While looking for a corresponding matched entry, look for matched entry in the sequence from top row to bottom row listed in the following table. If you find any matched entry (according to any of the rules tabulated below) then perform the action mentioned in the 'Action' column in that matched rule. =========================================================================== |Search |SAS | Phy Mask | Port | Possibilities| Action | |every |Address | or | Number | | required | |entry |matched?| subset of| matched?| | | |in below| | phy mask | | | | |sequence| | matched? | | | | =========================================================================== | 1 |matched | matched | matched | nothing |* unmark HBA port | | | | | | changed |table entry as | | | | | | |dirty | --------------------------------------------------------------------------- | 2 |matched | matched | not | port number |* Update port | | | | | matched | is changed |number in the | | | | | | |matched port table | | | | | | |entry | | | | | | |* unmask HBA port | | | | | | |table entry as | | | | | | |dirty | --------------------------------------------------------------------------- | 3.a |matched | subset of| matched |some phys |* Add these new | | | | phy mask | (or) |might have |phys to current | | | | matched | not |enabled which |port in STL | | | | | matched |are previously|* Update phy mask | | | | | (but |disabled |field in HBA's port| | | | | first | |table's matched | | | | | look for| |entry, | | | | | matched | |* Update port | | | | | one) | |number in the | | | | | | |matched port | | | | | | |table entry (if | | | | | | |port number is | | | | | | |changed), | | | | | | |* Unmask HBA port | | | | | | |table entry as | | | | | | |dirty | --------------------------------------------------------------------------- | 3.b |matched | subset of| matched |some phys |*Remove these phys | | | | phy mask | (or) |might have |from current port | | | | matched | not |disabled which|in STL | | | | | matched |are previously|* Update phy mask | | | | | (but |enabled |field in HBA's port| | | | | first | |tables's matched | | | | | look for| |entry, | | | | | matched | |*Update port number| | | | | one) | |in the matched port| | | | | | |table entry (if | | | | | | |port number is | | | | | | |changed), | | | | | | |* Unmask HBA port | | | | | | |table entry as | | | | | | |dirty | --------------------------------------------------------------------------- | 4 |matched | not | matched |A cable |*Remove old phys & | | | | matched | (or) |attached to an|new phys to current| | | | | not |expander is |port in STL | | | | | matched |changed to |* Update phy mask | | | | | |another HBA |field in HBA's port| | | | | |port during |tables's matched | | | | | |reset |entry, | | | | | | |*Update port number| | | | | | |in the matched port| | | | | | |table entry (if | | | | | | |port number is | | | | | | |changed), | | | | | | |* Unmask HBA port | | | | | | |table entry as | | | | | | |dirty | --------------------------------------------------------------------------- V.
