2020-01-02scsi: mpt3sas: Optimize mpt3sas driver loggingSreekanth Reddy
This improves mpt3sas driver default debug information collection and allows for a higher percentage of issues being able to be resolved with a first-time data capture. However, this improvement to balance the amount of debug data captured with the performance of driver. Enabled below print messages with out affecting the IO performance, 1. When task abort TM is received then print IO commands's timeout value and how much time this command has been outstanding. 2. Whenever hard reset occurs then print from where this hard reset has been issued. 3. Failure message should be displayed for failure scenarios without any logging level. 4. Added a print after driver successfully register or unregistered a target drive with the SML. This print will be useful for debugging the issue where the drive addition or deletion is hanging at SML. 5. During driver load time print request, reply, sense and config page pool's information such as its address, length and size. Also printed sg_tablesize information.

2020-01-02scsi: mpt3sas: Handle CoreDump state from watchdog threadSreekanth Reddy
Watchdog thread polls for IOC state every 1 second. If it detects that IOC state is in CoreDump state then it immediately stops the IOs and also clears the outstanding commands issued to the HBA firmware and then it will poll for IOC state to be out of CoreDump state and once it detects that IOC state is changed from CoreDump state to Fault state (or) CoreDumpTOSec number of seconds are elapsed then it will issue host reset operation and moves the IOC state to Operational state and resumes the IOs. Whenever any TM is received from SML then if driver detects the IOC state is in CoreDump state then it will wait for CoreDump state to be cleared and will host reset operation.

2020-01-02scsi: mpt3sas: Add support IOCs new state named COREDUMPSreekanth Reddy
New feature is added in HBA firmware where it copies the collected firmware logs in flash region named 'CoreDump' whenever HBA firmware faults occur. For copying the logs to CoreDump flash region firmware needs some time and hence it has introduced a new IOC state named "CoreDump" State. Whenever driver detects the CoreDump state then it means that some firmware fault has occurred and firmware is copying the logs to the coredump flash region. During this time driver should not perform any operation with the HBA, driver should wait for HBA firmware to move the IOC state from 'CoreDump' state to 'Fault' state once it's done with copying the logs to coredump region. Once driver detects the Fault state then it will issue the diag reset/host reset operation to move the IOC state from Fault to Operational state. Here the valid IOC state transactions w.r.t to this CoreDump state feature, Operational -> Fault: The IOC transitions to the Fault state when an operational error occurs AND CoreDump is not supported (or disabled) by the firmware(FW). Operational -> CoreDump: The IOC transitions to the CoreDump state when an operational error occurs AND CoreDump is supported & enabled by the FW. CoreDump -> Fault: A transition from CoreDump state to Fault state happens when the FW completes the CoreDump collection. CoreDump -> Reset: A transition out of the CoreDump state happens when the host sets the Reset Adapter bit in the System Diagnostic Register (Hard Reset). This reset action indicates that CoreDump took longer than the host time out. Firmware informs the driver about the maximum time that driver has to wait for firmware to transition the IOC state from 'CoreDump' to 'FAULT' state through 'CoreDumpTOSec' field of ManufacturingPage11 page. if this 'CoreDumpTOSec' field value is zero then driver will wait for max 15 seconds. Driver informs the HBA firmware that it supports this new IOC state named 'CoreDump' state by enabling COREDUMP_ENABLE flag in ConfigurationFlags field of ioc init request message. Current patch handles the CoreDump state only during HBA initialization and release scenarios where watchdog thread (which polls the IOC state in every one second) is disabled. Next subsequent patch handle the CoreDump state when watchdog thread is enabled. During HBA initialization or release execution time if driver detects the CoreDump state then driver will wait for maximum CoreDumpTOSec value seconds for FW to copy the logs. After that it will issue the diag reset operation to move the IOC state to Operational state.

2020-01-02scsi: mpt3sas: Add support for NVMe shutdownSreekanth Reddy
Introduce function _scsih_nvme_shutdown() to issue IO Unit Control message to IOC firmware with operation code 'shutdown'. This causes IOC firmware to issue NVMe shutdown commands to all NVMe drives attached to it. NVMe Shutdown: NVMe devices need to have a specific shutdown sequence performed before power is removed. For this, the IOC firmware needs to be notified when the system is being shutdown. So during the system shutdown time, driver issues an IO Unit Control request with operation code MPI26_CTRL_OP_SHUTDOWN to inform firmware that a shutdown is initiated. This shutdown command is issued only if NVMe devices are attached to the controller. During each NVMe device addition, driver reads pcie device page2 to get shutdown latency (e.g. drive's RTD3 Entry Latency) and updates the max latency value among the added NVMe drives in ioc->max_shutdown_latency. This is used as the timeout value for IO Unit Control command at the time of shutdown. When a NVMe drive is removed and its shutdown latency matches which ioc->max_shutdown_latency then ioc->max_shutdown_latency is updated to next max value (by iterating over the list of available devices). If the shutdown latency is 0, then default timeout is set to six seconds.

2019-12-27riscv: export flush_icache_all to modulesOlof Johansson
This is needed by LKDTM (crash dump test module), it calls flush_icache_range(), which on RISC-V turns into flush_icache_all(). On other architectures, the actual implementation is exported, so follow that precedence and export it here too. Fixes build of CONFIG_LKDTM that fails with: ERROR: "flush_icache_all" [drivers/misc/lkdtm/lkdtm.ko] undefined!

Running "stress-ng --enosys 4 -t 20 -v" showed a large number of kernel oops with "Unable to handle kernel paging request at virtual address" message. This happens when enosys stressor starts testing random non-valid syscalls. I forgot to redirect any syscall below -1 to sys_ni_syscall. With the patch kernel oops messages are gone while running stress-ng enosys stressor.

2019-12-27riscv: fix compile failure with EXPORT_SYMBOL() & !MMULuc Van Oostenryck
When support for !MMU was added, the declaration of __asm_copy_to_user() & __asm_copy_from_user() were #ifdefed out hence their EXPORT_SYMBOL() give an error message like: .../riscv_ksyms.c:13:15: error: '__asm_copy_to_user' undeclared here .../riscv_ksyms.c:14:15: error: '__asm_copy_from_user' undeclared here Since these symbols are not defined with !MMU it's wrong to export them. Same for __clear_user() (even though this one is also declared in include/asm-generic/uaccess.h and thus doesn't give an error message). Fix this by doing the EXPORT_SYMBOL() directly where these symbols are defined: inside lib/uaccess.S itself.

2019-12-25ata: ahci_brcm: Add missing clock management during recoveryFlorian Fainelli
The downstream implementation of ahci_brcm.c did contain clock management recovery, but until recently, did that outside of the libahci_platform helpers and this was unintentionally stripped out while forward porting the patch upstream. Add the missing clock management during recovery and sleep for 10 milliseconds per the design team recommendations to ensure the SATA PHY controller and AFE have been fully quiesced.

Set AHCI_HFLAG_DELAY_ENGINE for the BCM7425 AHCI controller thus making it conforming to the 'strict' AHCI implementation which this controller is based on. This solves long link establishment with specific hard drives (e.g.: Seagate ST1000VM002-9ZL1 SC12) that would otherwise have to complete the error recovery handling before finally establishing a succesful SATA link at the desired speed. We re-order the hpriv->flags assignment to also remove the NONCQ quirk since we can set the flag directly.
