| | | | | | | | | | | | | | generating one. When we are intentionally generating a firmware dump by executing the MBC_GEN_SYSTEM_ERROR command, the command actually times out. The normal course of action when a mailbox command times out is to take a firmware dump. However, in this special case we do not want to do this since the MBA_SYSTEM_ERR AEN already generates a firmware dump.

* [SCSI] qla2xxx: Fix for locking issue between driver ISR and mailbox routinesgurinder.shergill@hp.com2013-05-121-2/+0
| | | | | | | | | | | | | | | The driver uses ha->mbx_cmd_flags variable to pass information between its ISR and mailbox routines, however, it does so without the protection of any locks. Under certain conditions, this can lead to multiple mailbox command completions being signaled, which, in turn, leads to a false mailbox timeout error for the subsequently issued mailbox command. The issue occurs frequently but intermittenly with the Qlogic 8GFC mezz card during card initialization, resulting in card initialization failure.

* [SCSI] qla2xxx: Add LLD target-mode infrastructure for >= 24xx seriesNicholas Bellinger2012-05-221-7/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add LLD target mode for >= 24xx series HW. This code was originally based on external qla2x00t module based on 8.02.01-k4, and has been refactored to push the bulk of code into mainline qla2xxx.ko LLD -> qla_target.c. The implementation uses internal workqueues for I/O context submission into tcm_qla2xxx code, and includes the struct qla_tgt_func_tmpl API for external interaction to allow qla2xxx LDD to function without direct target-core dependencies: It also enables qla_target.c usage within existing qla2xxx LLD code. This includes: *) Addition of target mode specific members to existing data structures in qla_def.h and struct qla_hw_data->tgt_ops using qla_target.h:struct qla_tgt_func_tmpl *) Addition of struct qla_tgt_func_tmpl and direct calls into qla_target.c logic w/ qlt_* prefixed functions. *) Addition of qla_iocb.c:qla2x00_req_pkt() for ring processing, and qla2x00_issue_marker() for handling request/response queue processing for target mode operation *) Addition of various qla_tgt_mode_enabled() logic checks in qla24xx_nvram_config(), qla2x00_initialize_adapter(), qla2x00_rff_id(), qla2x00_abort_isp(), qla24xx_modify_vp_config(), and qla2x00_vp_abort_isp(). By default the new qlini_mode module parameter is setting initiator-mode to 'enabled' in order for 'modprobe qla2xxx' to continue to function as expected in initiator only mode. Enabling target-mode operation will currently require a: modprobe qla2xxx qlini_mode="disabled" in order to explictly disabled initiator mode and allow target-mode to be enabled via tcm_qla2xxx configfs fabric callers.

* [SCSI] qla2xxx: Verify login-state has transitioned to PRLI-completed.Andrew Vasquez2011-05-011-5/+12
| | | | | | | | | | | | | | | | | | Before driver's own internal state is marked as PLOGI/PRLI complete. This additional check closes a window seen with dual-personality initiator/target devices where a driver's PLOGI/PRLI request occurs within the window after the target's PLOGI request has completed, but prior to the target's PRLI arriving and processed by the firmware. Without this additional check, the firmware will return port-information stating that the port neither supports target nor initiator functions, causing the driver to register the rport prematurely to the FC-transport without the proper 'roles' being set.
