Fixed by making fast path trace functions as NOP as it was getting included in the inline functions of ethdev,mempool, cryptodev, etc(David) 4) Removed DALLOW_EXPERIMENTAL_API definition from individual driver files. Now it set as global using http://patches.dpdk.org/patch/67758/ patch (David) 5) Added new meson option(-Denable_trace_dp=true)for enabling the datapath trace point (David, Bruce) 6) Changed the authorship and Rewrote the programmer's guide based on the below feedback(Thomas) http://patches.dpdk.org/patch/67352/ v3: ~~ 1) Fix the following build issues reported by CI http://mails.dpdk.org/archives/test-report/2020-March/122060.html a) clang + i686 meson build issue(Fixed in the the patch meson: add libatomic as a global dependency for i686 clang) b) fixed build issue with FreeBSD with top of tree change. c) fixed missing experimental API for iavf and ice with meson build in avx512 files. v2: ~~ Addressed the following review comments from Mattias Rönnblom: 1) Changed from: typedef uint64_t* rte_trace_t; to typedef uint64_t rte_trace_t; Initially thought to make the handle as struct rte_trace { uint64_t val; } but changed to uint64_t for the following reasons a) It is opaque to the application and it will fix the compile-time type check as well. b) The handle has an index that will point to an internal slow-path structure so no ABI change required in the future. c) RTE_TRACE_POINT_DEFINE need to expose trace object. So it is better to keep as uint64_t and avoid one more indirection for no use. 2) Changed: from: enum rte_trace_mode_e { to: enum rte_trace_mode { 3) removed [out] "found" param from rte_trace_pattern() and rte_trace_regexp() 4) Changed rte_trace_from_name to rte_trace_by_name 5) rte_trace_is_dp_enabled() return bool now 6) in __rte_trace_point_register() the argument fn change to register_fn 7) removed !! from rte_trace_is_enabled() 8) Remove uninitialized "rc warning" from rte_trace_pattern() and rte_trace_regexp() 9) fixup bool return type for trace_entry_compare() 10) fixup calloc casting in trace_mkdir() 11) check fclose() return in trace_meta_save() and trace_mem_save() 12) rte_trace_ctf_* macro cleanup 13) added release notes 14) fix build issues reported by CI http://mails.dpdk.org/archives/test-report/2020-March/121235.html This patch set contains ~~~~~~~~~~~~~~~~~~~~~~~~ # The native implementation of common trace format(CTF)[1] based tracer # Public API to create the trace points. # Add tracepoints to eal, ethdev, mempool, eventdev and cryptodev library for tracing support # A unit test case # Performance test case to measure the trace overhead. (See eal/trace: # add trace performance test cases, patch) # Programmers guide for Trace support(See doc: add trace library guide, # patch) # Tested OS: ~~~~~~~~~~~ - Linux - FreeBSD # Tested open source CTF trace viewers ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Babeltrace - Tracecompass # Trace overhead comparison with LTTng ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ trace overhead data on x86:[2] # 236 cycles with LTTng(>100ns) # 18 cycles(7ns) with Native DPDK CTF emitter.(See eal/trace: add trace # performance test cases patch) trace overhead data on arm64: # 312 cycles to 1100 cycles with LTTng based on the class of arm64 CPU. # 11 cycles to 13 cycles with Native DPDK CTF emitter based on the class of arm64 CPU. 18 cycles(on x86) vs 11 cycles(on arm64) is due to rdtsc() overhead in x86. It seems rdtsc takes around 15cycles in x86. More details: ~~~~~~~~~~~~~ # The Native DPDK CTF trace support does not have any dependency on third-party library. The generated output file is compatible with LTTng as both are using CTF trace format. The performance gain comes from: 1) exploit dpdk worker thread usage model to avoid atomics and use per core variables 2) use hugepage, 3) avoid a lot function pointers in fast-path etc 4) avoid unaligned store for arm64 etc Features: ~~~~~~~~~ - No specific limit on the events. A string-based event like rte_log for pattern matching - Dynamic enable/disable support. - Instructmention overhead is ~1 cycle. i.e cost of adding the code wth out using trace feature. - Timestamp support for all the events using DPDK rte_rtdsc - No dependency on another library. Clean room native implementation of CTF.
