ae89daab818d0b948399026392d2ab871da8ad47 - trace: add concept of "owner" to trace files

Sat, 30 Mar 2024 00:00:32 +0000

trace: add concept of "owner" to trace filesAn "owner" is now represented by a textual string describing the owner ofa trace event.A trace file can have up to 16K outstanding owners at any given time. We needthis many to be able to track all of the various NVMe-oF qpairs, bdevs,NVMe driver qpairs, accel channels, etc. A library creating trace eventscan call spdk_trace_register_owner() with a description string to allocate aa 16-bit owner_id. This owner_id is then passed as a parameter tospdk_trace_record().Libraries can change the description of a registered owner by callingspdk_trace_owner_set_description(). This can be useful for cases like NVMe-oF,where where a newly established qpair may only have a source IP/port, but latercan be changed to also add the subsystem nqn once the CONNECT command arrives.A library is responsible for calling spdk_trace_unregister_owner() once theassociated object is destroyed (i.e. a qpair disconnects or a bdev isunregistered).An owner lifetime is tracked by recording the tsc when the owner wasregistered. This allows the trace app to handle the case where an owner_idgets reused during the span of a trace file.Signed-off-by: Jim Harris Change-Id: I79c9979a0769c32a85ee646c8237fe8329993c45Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/22646Tested-by: SPDK CI Jenkins Reviewed-by: Shuhei Matsumoto Community-CI: Mellanox Build BotReviewed-by: Konrad Sztyber List of files: /spdk/lib/trace/spdk_trace.map

Fri, 29 Mar 2024 23:58:35 +0000

trace: rename owner to owner_typeWe will be adding the real concept of an "owner" in upcoming patches. So changethe existing "owner" to "owner_type" which more accurate reflects its meaning.For example, an "owner_type" can be OWNER_BDEV, but an actual "owner" wouldbe some specific bdev identified by its name.Signed-off-by: Jim Harris Change-Id: Ieb25eb5a574a88b3812291f2345796e5bb66a54fReviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/22645Reviewed-by: Konrad Sztyber Community-CI: Mellanox Build BotReviewed-by: Shuhei Matsumoto Tested-by: SPDK CI Jenkins List of files: /spdk/lib/trace/spdk_trace.map

trace: enable adding relations between tracesCurrently we do not have any way to connect traces from differentmodules in SPDK. This change modifies our trace libraryand app/trace to handle adding relations between trace pointsand a trace object.Additionally this patch adds classes and fields to structsinside trace.py to prepare it for future patches implementingprinting relation information.Change-Id: Ia09d01244d923957d589fd37e6d4c98f9f7bbd07Signed-off-by: Krzysztof Karas Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/9620Reviewed-by: Tomasz Zawadzki Reviewed-by: Konrad Sztyber Reviewed-by: Jim Harris Tested-by: SPDK CI Jenkins Community-CI: Broadcom CI List of files: /spdk/lib/trace/spdk_trace.map

f301d156f1e38fba27cba850d05ab221dd3574c8 - lib/trace: variable number of tracepoint arguments

Mon, 17 May 2021 13:10:39 +0000

lib/trace: variable number of tracepoint argumentsThis patch allows tracepoint to record a variable number of arugments.An additional function has been added,`spdk_trace_register_description_ext()`, which allows the user toregister definitions for tracepoints specifying all the arugments thatthey accept. Users can also call `spdk_trace_register_description()` toregister tpoints with a single argument (or none).Currently, all of the tracepoint arguments need to be passed asuint64_t.The trace record functions use variable arguments and rely on tracepointdescription to know the order and the format of the arguments passed.That means that the user needs to take care that they're always in sync.Moreover, this patch extends the tracepoint entry size from 32B to 64B,meaning that there are 40B that can be utilized for passing arguments,which in turn means that there can be up to 5 arguments per tracepoint.Signed-off-by: Konrad Sztyber Change-Id: I9993eabb2663078052439320e6d2f6ae607a47ffReviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/7956Tested-by: SPDK CI Jenkins Reviewed-by: Aleksey Marchuk Reviewed-by: Jim Harris Community-CI: Mellanox Build Bot List of files: /spdk/lib/trace/spdk_trace.map
