NVME Initiator: Base modifications This patch adds base modifications for NVME initiator support. The base modifications consist of: - Formal split of SLI3 rings from SLI-4 WQs (sometimes referred to as rings as well) as implementation now widely varies between the two. - Addition of configuration modes: SCSI initiator only; NVME initiator only; NVME target only; and SCSI and NVME initiator. The configuration mode drives overall adapter configuration, offloads enabled, and resource splits. NVME support is only available on SLI-4 devices and newer fw. - Implements the following based on configuration mode: - Exchange resources are split by protocol; Obviously, if only 1 mode, then no split occurs. Default is 50/50. module attribute allows tuning. - Pools and config parameters are separated per-protocol - Each protocol has it's own set of queues, but share interrupt vectors. SCSI: SLI3 devices have few queues and the original style of queue allocation remains. SLI4 devices piggy back on an "io-channel" concept that eventually needs to merge with scsi-mq/blk-mq support (it is underway). For now, the paradigm continues as it existed prior. io channel allocates N msix and N WQs (N=4 default) and either round robins or uses cpu # modulo N for scheduling. A bunch of module parameters allow the configuration to be tuned. NVME (initiator): Allocates an msix per cpu (or whatever pci_alloc_irq_vectors gets) Allocates a WQ per cpu, and maps the WQs to msix on a WQ # modulo msix vector count basis. Module parameters exist to cap/control the config if desired. - Each protocol has its own buffer and dma pools. I apologize for the size of the patch. Signed-off-by: -

Dan Carpenter <dan.carpenter@oracle.com> reported this: The patch 9c46b867: "scsi: ufs-qcom: dump additional testbus registers" from Feb 3, 2017, leads to the following static checker warning: drivers/scsi/ufs/ufs-qcom.c:1531 ufs_qcom_testbus_cfg_is_ok() warn: impossible condition '(host->testbus.select_minor > 255) => (0-255 > 255)' drivers/scsi/ufs/ufs-qcom.c 1517 static bool ufs_qcom_testbus_cfg_is_ok(struct ufs_qcom_host *host) 1518 { 1519 if (host->testbus.select_major >= TSTBUS_MAX) { 1520 dev_err(host->hba->dev, 1521 "%s: UFS_CFG1[TEST_BUS_SEL} may not equal 0x%05X\n", 1522 __func__, host->testbus.select_major); 1523 return false; 1524 } 1525 1526 /* 1527 * Not performing check for each individual select_major 1528 * mappings of select_minor, since there is no harm in 1529 * configuring a non-existent select_minor 1530 */ 1531 if (host->testbus.select_minor > 0xFF) { ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ It might make sense to keep this check. I don't know. But it's confusing that 0xFF is a magic number.

This change removes it. Reported-by:

When we have turned off RTC support, the smartpqi driver fails to build: ERROR: "rtc_time64_to_tm" [drivers/scsi/smartpqi/smartpqi.ko] undefined! This is easily avoided by using the generic 'struct tm' based helper rather than the RTC specific one. While fixing this, I noticed that even though the driver uses time64_t for storing seconds, it gets them from the old 32-bit struct timeval. To address this, we can simplify the code by calling ktime_get_real_seconds() directly. Fixes: 6c223761 ("smartpqi: initial commit of Microsemi smartpqi driver") Signed-off-by:

The driver does not unlock the reply queue spin lock after handling SMART adapter events. Instead it might attempt to unlock an already unlocked spin lock. Fixed by making sure the driver locks the spin lock before freeing it. Thank you dan for finding this issue out. Fixes: 6223a39f (scsi: aacraid: Added support for hotplug) Reported-by:

Currently the adapter firmware does not save outstanding I/O's log information when an IOP reset is triggered. This is problematic when trying to root cause and debug issues. Fixed by adding sync command to trigger I/O log file save in the adapter firmware before issuing an IOP reset. Signed-off-by:

The driver currently checks the SELF_TEST_FAILED first and then KERNEL_PANIC next. Under error conditions(boot code failure) both SELF_TEST_FAILED and KERNEL_PANIC can be set at the same time. The driver has the capability to reset the controller on an KERNEL_PANIC, but not on SELF_TEST_FAILED. Fixed by first checking KERNEL_PANIC and then the others.

Currently driver checks the health status of the adapter once every 24 hours. When that happens the driver becomes dependent on the kernel to figure out if the adapter is misbehaving. This might take some time (when the adapter is idle). The driver currently has support to restart/recover the controller when it fails, and decreasing the time interval will help. Fixed by decreasing check interval from 24 hours to 1 minute Signed-off-by:

During the IOP reset stress testing, it was found that the drives can be marked offline when the adapter controller crashes and IO's are running in parallel. When the controller does come back from the reset, the drive that is marked offline is not exposed. Fixed by removing and adding drives that are marked offline. In addition invoke a scsi host bus rescan to capture any additional configuration changes. Signed-off-by:

aac_command_thread checks on the health of controller periodically, using aac_check_health. If the status is an error state KERNEL_PANIC or anything else. The driver will attempt to restart the adapter, but the response is not checked in aac_command_thread. This allows the periodic sync to go thru and lead the driver to a hung state. Fixed by terminating the periodic loop(intended per original design), if the controller is not restored to a healthy state.

This issue showed up on a kdump debug(single CPU on powerkvm), when EEH errors rendered the adapter unusable. The driver correctly detected the issue and attempted to restart the controller, in doing so the driver attempted to read the status registers of the controller. This triggered additional eeh errors which continued for a good 6 minutes. Fixed by returning without waiting when EEH error is reported. Signed-off-by:

The channel being used for raw srb commands is retrieved from the utility sent fibs and is converted into physical channel id. The driver does not need to to do this since the management utility sends the correct channel id in the first place and in addition the driver sets inaccurate information in the cmd sent to the firmware and gets an invalid response. Fixed by using channel id from srb command. Cc: stable@vger.kernel.org Fixes: 423400e6 ("scsi: aacraid: Include HBA direct interface") Signed-off-by:
