That is where development now # takes place and myself and Namhyung Kim have write access, more # people to come as we emulate other maintainer groups. # # perf record: # # - Record kernel data maps when 'perf record --data' is used, so that # global variables can be resolved and used in tools that do data # profiling. # # perf trace: # # - Remove the old, experimental support for BPF events in which a .c # file was passed as an event: "perf trace -e hello.c" to then get # compiled and loaded. # # The only known usage for that, that shipped with the kernel as an # example for such events, augmented the raw_syscalls tracepoints and # was converted to a libbpf skeleton, reusing all the user space # components and the BPF code connected to the syscalls. # # In the end just the way to glue the BPF part and the user space # type beautifiers changed, now being performed by libbpf skeletons. # # The next step is to use BTF to do pretty printing of all syscall # types, as discussed with Alan Maguire and others. # # Now, on a perf built with BUILD_BPF_SKEL=1 we get most if not all # path/filenames/strings, some of the networking data structures, # perf_event_attr, etc, i.e. systemwide tracing of nanosleep calls # and perf_event_open syscalls while 'perf stat' runs 'sleep' for 5 # seconds: # # # perf trace -a -e nanosleep,perf perf stat -e cycles,instructions sleep 5 # 0.000 ( 9.034 ms): perf/327641 perf_event_open(attr_uptr: { type: 0 (PERF_TYPE_HARDWARE), size: 136, config: 0 (PERF_COUNT_HW_CPU_CYCLES), sample_type: IDENTIFIER, read_format: TOTAL_TIME_ENABLED\|TOTAL_TIME_RUNNING, disabled: 1, inherit: 1, enable_on_exec: 1, exclude_guest: 1 }, pid: 327642 (perf), cpu: -1, group_fd: -1, flags: FD_CLOEXEC) = 3 # 9.039 ( 0.006 ms): perf/327641 perf_event_open(attr_uptr: { type: 0 (PERF_TYPE_HARDWARE), size: 136, config: 0x1 (PERF_COUNT_HW_INSTRUCTIONS), sample_type: IDENTIFIER, read_format: TOTAL_TIME_ENABLED\|TOTAL_TIME_RUNNING, disabled: 1, inherit: 1, enable_on_exec: 1, exclude_guest: 1 }, pid: 327642 (perf-exec), cpu: -1, group_fd: -1, flags: FD_CLOEXEC) = 4 # ?

This seems just a # tool limitation, the kernel probably has all that is needed. # # perf tests: # # - Fix a reference count related leak in the dlfilter v0 API where the # result of a thread__find_symbol_fb() is not matched with an # addr_location__exit() to drop the reference counts of the resolved # components (machine, thread, map, symbol, etc). Add a dlfilter test # to make sure that doesn't regresses. # # - Lots of fixes for the 'perf test' written in shell script related # to problems found with the shellcheck utility. # # - Fixes for 'perf test' shell scripts testing features enabled when # perf is built with BUILD_BPF_SKEL=1, such as 'perf stat' bpf # counters. # # - Add perf record sample filtering test, things like the following # example, that gets implemented as a BPF filter attached to the # event: # # # perf record -e task-clock -c 10000 --filter 'ip < 0xffffffff00000000' # # - Improve the way the task_analyzer test checks if libtraceevent is # linked, using 'perf version --build-options' instead of the more # expensinve 'perf record -e "sched:sched_switch"'. # # - Add support for riscv in the mmap-basic test. (This went as well # via the RiscV tree, same contents). # # libperf: # # - Implement riscv mmap support (This went as well via the RiscV tree, # same contents). # # perf script: # # - New tool that converts perf.data files to the firefox profiler # format so that one can use the visualizer at # https://profiler.firefox.com/. Done by Anup Sharma as part of this # year's Google Summer of Code. # # One can generate the output and upload it to the web interface but # Anup also automated everything: # # perf script gecko -F 99 -a sleep 60 # # - Support syscall name parsing on arm64. # # - Print "cgroup" field on the same line as "comm". # # perf bench: # # - Add new 'uprobe' benchmark to measure the overhead of uprobes # with/without BPF programs attached to it. # # - breakpoints are not available on power9, skip that test. # # perf stat: # # - Add #num_cpus_online literal to be used in 'perf stat' metrics, and # add this extra 'perf test' check that exemplifies its purpose: # # TEST_ASSERT_VAL("#num_cpus_online", # expr__parse(&num_cpus_online, ctx, "#num_cpus_online") == 0); # TEST_ASSERT_VAL("#num_cpus", expr__parse(&num_cpus, ctx, "#num_cpus") == 0); # TEST_ASSERT_VAL("#num_cpus >= #num_cpus_online", num_cpus >= num_cpus_online); # # Miscellaneous: # # - Improve tool startup time by lazily reading PMU, JSON, sysfs data. # # - Improve error reporting in the parsing of events, passing YYLTYPE # to error routines, so that the output can show were the parsing # error was found. # # - Add 'perf test' entries to check the parsing of events # improvements. # # - Fix various leak for things detected by -fsanitize=address, mostly # things that would be freed at tool exit, including: # # - Free evsel->filter on the destructor. # # - Allow tools to register a thread->priv destructor and use it in # 'perf trace'. # # - Free evsel->priv in 'perf trace'. # # - Free string returned by synthesize_perf_probe_point() when the # caller fails to do all it needs. # # - Adjust various compiler options to not consider errors some # warnings when building with broken headers found in things like # python, flex, bison, as we otherwise build with -Werror. Some for # gcc, some for clang, some for some specific version of those, some # for some specific version of flex or bison, or some specific # combination of these components, bah. # # - Allow customization of clang options for BPF target, this helps # building on gentoo where there are other oddities where BPF targets # gets passed some compiler options intended for the native build, so # building with WERROR=0 helps while these oddities are fixed. # # - Dont pass ERR_PTR() values to perf_session__delete() in 'perf top' # and 'perf lock', fixing some segfaults when handling some odd # failures. # # - Add LTO build option. # # - Fix format of unordered lists in the perf docs # (tools/perf/Documentation) # # - Overhaul the bison files, using constructs such as YYNOMEM. # # - Remove unused tokens from the bison .y files. # # - Add more comments to various structs. # # - A few LoongArch enablement patches. # # Vendor events (JSON): # # - Add JSON metrics for Yitian 710 DDR (aarch64).
