2012-05-22perf tools: Add union u64_swap type for swapping u64 dataJiri Olsa
The following union: union { u64 val64; u32 val32[2]; } u; is used on more than one place in perf code and will be used more in upcomming patches. Adding union u64_swap to have it defined globaly so we dont need to redefine it all the time.

2012-05-22perf tools: Carry perf_event_attr bitfield throught different endiansJiri Olsa
When the perf data file is read cross architectures, the perf_event__attr_swap function takes care about endianness of all the struct fields except the bitfield flags. The bitfield flags need to be transformed as well, since the bitfield binary storage differs for both endians. ABI says: Bit-fields are allocated from right to left (least to most significant) on little-endian implementations and from left to right (most to least significant) on big-endian implementations. The above seems to be byte specific, so we need to reverse each byte of the bitfield. 'Internet' also says this might be implementation specific and we probably need proper fix and carry perf_event_attr bitfield flags in separate data file FEAT_ section. Thought this seems to work for now. Note, running following to test perf endianity handling: test 1) - origin system: # perf record -a -- sleep 10 (any perf record will do) # perf report > report.origin # perf archive perf.data - copy the perf.data, report.origin and perf.data.tar.bz2 to a target system and run: # tar xjvf perf.data.tar.bz2 -C ~/.debug # perf report > report.target # diff -u report.origin report.target - the diff should produce no output (besides some white space stuff and possibly different date/TZ output) test 2) - origin system: # perf record -ag -fo /tmp/perf.data -- sleep 1 - mount origin system root to the target system on /mnt/origin - target system: # perf script --symfs /mnt/origin -I -i /mnt/origin/tmp/perf.data \ --kallsyms /mnt/origin/proc/kallsyms - complete perf.data header is displayed Signed-off-by: Jiri Olsa <jolsa@redhat.com> Reviewed-by: David Ahern <dsahern@gmail.com> Tested-by: David Ahern <dsahern@gmail.com> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1337151548-2396-3-git-send-email-jolsa@redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2012-05-22[SCSI] tcm_qla2xxx: Add >= 24xx series fabric module for target-coreNicholas Bellinger
This patch adds support for tcm_qla2xxx fabric module for target-core using the new qla_target.c LLD logic. This includes support for explict NodeACLs via configfs using tcm_qla2xxx_setup_nacl_from_rport() from libfc struct fc_host->rports, and demo-mode support for virtual LUN=0 access. This patch also adds support for using tcm_qla2xxx_lport->lport_fcport_map and ->lport_loopid_map of btree_head32 to track struct se_node_acl pointers for individual 24-bit Port ID and 16-bit Loop ID values w/ qla_target_template ->find_sess_by_s_id() and ->find_sess_by_loop_id() used in a number of locations into the primary I/O dispatch logic in qla_target.c LLD code. The main piece for FC Nexus setup is in tcm_qla2xxx_check_initiator_node_acl(), which calls tcm_qla2xxx_set_sess_by_[s_id,loop_id]() to setup our lport->lport_fcport_map and lport_loopid_map pointers respectively, and register the new nexus with TCM via __transport_register_session(). (nab: Add qla_tgt_mgmt_cmd usage with TARGET_SCF_ACK_KREF during TMRs + change tcm_qla2xxx_nacl->nport_id to u32 (DanC)) (danc: tcm_qla2xxx: checking for NULL instead of IS_ERR()) (roland: Fix up v3.5 breakage for removal of transport_do_task_sg_chain + Add hook so qla_target code can shutdown sessions) (steveh: Convert FC address map from flat array to btree) (randy: fix qla2xxx printk format warnings for size_t) (joern: Make most of tcm_qla2xxx static + remove unnecessary workqueue_struct prototypes + use WWN_SIZE instead of hard-coded constants) Signed-off-by: Nicholas A.

2012-05-22[SCSI] qla2xxx: Add LLD target-mode infrastructure for >= 24xx seriesNicholas Bellinger
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.

Optimized queuecommand handler's to eliminate double head-room checks. The checks are moved inside the 1st if-loop otherwise you would end up checking twice when there is enough head room.

2012-05-22[SCSI] scsi_pm: resume device if suspend failedAaron Lu
For scsi devices which use scsi bus runtime callback, runtime suspend will call scsi_dev_type_suspend, and if the drv->suspend failed, the device will still be in active state. But since scsi_device_quiesce is called, the device will not be able to respond any more commands. So add a check here to see if err occured, if so, bring the device back to normal state with scsi_device_resume.

2012-05-22sh: intc: Kill off special reservation interface.Paul Mundt
At present reserving the IRLs in the IRQ bitmap in addition to the dropping of the legacy IRQ pre-allocation prevent IRL IRQs from being allocated for the x3proto board. The only reason to permit reservations was to lock down possible hardware vectors prior to dynamic IRQ scanning, but this doesn't matter much given that the hardware controller configuration is sorted before we get around to doing any dynamic IRQ allocation anyways. Beyond that, all of the tables are __init annotated, so quite a bit more work would need to be done to support reconfiguring things like IRL controllers on the fly, much more than would ever make it worth the hassle.
