[SCSI] qla2xxx: Add LLD target-mode infrastructure for >= 24xx series 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: Add LLD target-mode infrastructure for >= 24xx series 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.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

qla2xxx: Add framework for async fabric discovery Currently code performs a full scan of the fabric for every RSCN. Its an expensive process in a noisy large SAN. This patch optimizes expensive fabric discovery process by scanning switch for the affected port when RSCN is received. Currently Initiator Mode code makes login/logout decision without knowledge of target mode. This causes driver and firmware to go out-of-sync. This framework synchronizes both initiator mode personality and target mode personality in making login/logout decision. This patch adds following capabilities in the driver - Send Notification Acknowledgement asynchronously. - Update session/fcport state asynchronously. - Create a session or fcport struct asynchronously. - Send GNL asynchronously. The command will ask FW to provide a list of FC Port entries FW knows about. - Send GPDB asynchronously. The command will ask FW to provide detail data of an FC Port FW knows about or perform ADISC to verify the state of the session. - Send GPNID asynchronously. The command will ask switch to provide WWPN for provided NPort ID. - Send GPSC asynchronously. The command will ask switch to provide registered port speed for provided WWPN. - Send GIDPN asynchronously. The command will ask the switch to provide Nport ID for provided WWPN. - In driver unload path, schedule all session for deletion and wait for deletion to complete before allowing driver unload to proceed.

This framework synchronizes both initiator mode personality and target mode personality in making login/logout decision. This patch adds following capabilities in the driver - Send Notification Acknowledgement asynchronously. - Update session/fcport state asynchronously. - Create a session or fcport struct asynchronously. - Send GNL asynchronously. The command will ask FW to provide a list of FC Port entries FW knows about. - Send GPDB asynchronously. The command will ask FW to provide detail data of an FC Port FW knows about or perform ADISC to verify the state of the session. - Send GPNID asynchronously. The command will ask switch to provide WWPN for provided NPort ID. - Send GPSC asynchronously. The command will ask switch to provide registered port speed for provided WWPN. - Send GIDPN asynchronously. The command will ask the switch to provide Nport ID for provided WWPN. - In driver unload path, schedule all session for deletion and wait for deletion to complete before allowing driver unload to proceed.

[SCSI] qla2xxx: Add LLD target-mode infrastructure for >= 24xx series 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.

qla2xxx: Add framework for async fabric discovery Currently code performs a full scan of the fabric for every RSCN. Its an expensive process in a noisy large SAN. This patch optimizes expensive fabric discovery process by scanning switch for the affected port when RSCN is received. Currently Initiator Mode code makes login/logout decision without knowledge of target mode. This causes driver and firmware to go out-of-sync. This framework synchronizes both initiator mode personality and target mode personality in making login/logout decision. This patch adds following capabilities in the driver - Send Notification Acknowledgement asynchronously. - Update session/fcport state asynchronously. - Create a session or fcport struct asynchronously. - Send GNL asynchronously. The command will ask FW to provide a list of FC Port entries FW knows about. - Send GPDB asynchronously. The command will ask FW to provide detail data of an FC Port FW knows about or perform ADISC to verify the state of the session. - Send GPNID asynchronously. The command will ask switch to provide WWPN for provided NPort ID. - Send GPSC asynchronously. The command will ask switch to provide registered port speed for provided WWPN. - Send GIDPN asynchronously. The command will ask the switch to provide Nport ID for provided WWPN. - In driver unload path, schedule all session for deletion and wait for deletion to complete before allowing driver unload to proceed.
