This patch adds the information of the different values that can be used in the module parameter 'debug_logging', as it is shown below: $ modinfo bnx2fc [...] parm: debug_logging:Option to enable extended logging, Default is 0 - no logging. 0x01 - SCSI cmd error, cleanup. 0x02 - Session setup, cleanup, etc. 0x04 - lport events, link, mtu, etc. 0x08 - ELS logs. 0x10 - fcoe L2 fame related logs. 0xff - LOG all messages.

Update the SCSI hosts module to use ida to manage its host_no index instead of an atomic integer. This means that the SCSI host number will now be reclaimable. Use the ida "simple" mechanism, since there should be no need for a separate spin lock current usage. Ida was chosen over idr because the hosts module already has its own instance and locking mechanisms that aren't easily changed. Reviewed-by:

This patch will add capability in driver to tell firmware that it can throttle IOs in case controller's queue depth is downgraded post OFU (online firmware upgrade). This feature will ensure firmware can be downgraded from higher queue depth to lower queue depth without needing system reboot. Added throttling code in IO path of driver, in case OS tries to send more IOs than post OFU firmware's queue depth. Signed-off-by:

1. For iMR controllers, firmware will report two queue depths: - Controller-wide queue depth - LDIO queue depth (240) Controller-wide queue depth will be greater among the two. Using this new feature, iMR can provide larger Queue depth(QD) for JBOD and limited QD for Virtual Disk(VD). 2. megaraid_sas driver will throttle read/write LDIOs based on "LDIO Queue Depth". 3. Dual queue depth can be enabled/disabled via module parameter. It is enabled by default if the firmware supports it. Only specific firmware builds will enable the feature. 4. Added sysfs parameter "ldio_outstanding" which permits querying the number of outstanding LDIO requests at runtime. Signed-off-by:

build_and_issue_cmd should return SCSI_MLQUEUE_HOST_BUSY for a few error cases instead of returning 1. Signed-off-by:

This patch will create a reply queue pool for each MSI-X index and will provide an array of base addresses instead of the single address of legacy mode. Using this new interface the driver can support higher queue depths through scattered DMA pools. If array mode is not supported driver will fall back to the legacy method of reply pool allocation. This limits controller queue depth to 1K max. To enable a queue depth of more than 1K driver requires firmware to support array mode and scratch_pad3 will provide the new queue depth value. When RDPQ is used, downgrading to an older firmware release should not be permitted. This may cause firmware fault and is not supported. Signed-off-by:

Firmware will fill out per-LD data to tell driver whether a particular LD supports region lock bypass. If yes, then driver will send non-FP LDIO to region lock bypass FIFO. With this change in driver, firmware will optimize certain code to improve performance. Signed-off-by:

This patch will update device Queue depth based on interface type(SAS, SATA..) for sysPDs. For Virtual disks(VDs), there will be no change in queue depth (will remain 256). To fetch interface type (SAS or SATA or FC..) of syspD, driver will send DCMD MR_DCMD_PD_GET_INFO. Signed-off-by:

This patch adds task management for SCSI commands. Added functions are task abort and target reset. 1. Currently, megaraid_sas driver performs controller reset when any IO times out. With task management support added, task abort and target reset will be tried to recover timed out IO. If task management fails, then controller reset will be performaned. If the task management request times out, fail the request and escalate to the next level (controller reset). 2. mr_device_priv_data will be allocated for all generations of controller, but is_tm_capable flag will never be set for controllers (prior to Invader series) as firmware support is not available for task management. 3. Task management capable firmware will set is_tm_capable flag in firmware API. Signed-off-by:

This patch will do proper error handling for DCMD timeout failure cases for Fusion adapters: 1. For MFI adapters, in case of DCMD timeout (DCMD which must return SUCCESS) driver will call kill adapter. 2. What action needs to be taken in case of DCMD timeout is decided by function dcmd_timeout_ocr_possible(). DCMD timeout causing OCR is applicable to the following commands: MR_DCMD_PD_LIST_QUERY MR_DCMD_LD_GET_LIST MR_DCMD_LD_LIST_QUERY MR_DCMD_CTRL_SET_CRASH_DUMP_PARAMS MR_DCMD_SYSTEM_PD_MAP_GET_INFO MR_DCMD_LD_MAP_GET_INFO 3. If DCMD fails from driver init path there are certain DCMDs which must return SUCCESS. If those DCMDs fail, driver bails out. For optional DCMDs like pd_info etc., driver continues without executing certain functionality. Signed-off-by:

This patch will do synhronization between OCR function and AEN function using "reset_mutex" lock. reset_mutex will be acquired only in the first half of the AEN function which issues a DCMD. Second half of the function which calls SCSI API (scsi_add_device/scsi_remove_device) should be out of reset_mutex to avoid deadlock between scsi_eh thread and driver. During chip reset (inside OCR function), there should not be any PCI access and AEN function (which is called in delayed context) may be firing DCMDs (doing PCI writes) when chip reset is happening in parallel which will cause FW fault. This patch will solve the problem by making AEN thread and OCR thread mutually exclusive. Signed-off-by:

The hpsa driver uses this function to cleanup inquiry data. Our new pqi driver will also use this function. This function was copied into both drivers. This patch exports sanitize_inquiry_string so the hpsa and the pqi drivers can use this function directly. Suggested-by:

If we fail to queue an srb for an async login we should set the relogin flag so it will be retried as the reason for the queuing failure was most likely transient. Failure to do this can lead to failed paths as login is never retried if the relogin flag is not set. Signed-off-by:
