* [SCSI] qla2xxx: Add LLD target-mode infrastructure for >= 24xx seriesNicholas Bellinger2012-05-221-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (nab: Convert to qlini_mode='enabled' by default in qla_target.c) (joern: Remove loop_id from qla_tgt_make_local_sess() arguments + Remove unused s_id + fix s_id endianness bug + simplify qla_tgt_abort_work) (gerard: fix section __exit mismatch in qla_tgt_exit) (arun: Capture ATIO queue during firmware dump + Send SCR in target mode + Target mode review comments) (roland: Don't create duplicate target sessions to address tearing down ACLs with IO in flight + Add missing call to qlt_fc_port_deleted call during qla2x00_schedule_rport_del timeout) Signed-off-by: Nicholas A.

* [SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting.Arun Easi2011-08-271-34/+21Star
| | | | | | | | | | | | | | | | | | | | | This fix: - Disables app tag peeking; correct tag check will be added when the SCSI API is available. - Always derive ref_tag from scsi_get_lba() - Removes incorrect swap of FCP_LUN in FCP_CMND - Moves app-tag error check before ref-tag check. The reason being, currently there is no interface in SCSI to retrieve the app-tag for protection I/Os, so driver puts zero for app-tag in the firmware interface, but requests not to validate it, but when a ref-tag error is detected by firmware, it would put expected/actual tags for all the protection tags (guard/app/ref). As driver checks for app tag error first, a ref-tag error is incorrectly flagged as app-tag error. - Convert HBA specific checks to capability based.

* [SCSI] qla2xxx: add support for multi-queue adapterAnirban Chakraborty2008-12-291-58/+100
| | | | | | | | | | | | | | | | | | Following changes have been made. 1. qla_hw_data structure holds an array for request queue pointers, and an array for response queue pointers. 2. The base request and response queues are created by default. 3. Additional request and response queues are created at the time of vport creation. If queue resources are exhausted during vport creation, newly created vports use the default queue. 4. Requests are sent to the request queue that the vport was assigned in the beginning. 5. Responses are completed on the response queue with which the request queue is associated with.
