For now the type based scnprintf routines (pid_t, umode_t, etc) and the ones based in well known arg name based ("fd", etc) gets associated with tracepoint args of that type. A tracepoint only arg, "msr", for the msr:{write,read}_msr gets added as an initial step. - Introduce syscall_arg_fmt->strtoul() methods to be the reverse operation of ->scnprintf(), i.e. to go from a string to an integer. - Implement --filter, just like in 'perf record', that affects the tracepoint events specied thus far in the command line, use the ->strtoul() methods to allow strings in tables associated with beautifiers to the integers the in-kernel tracepoint (eBPF later) filters expect, e.g.: # perf trace --max-events 1 -e sched:*ipi --filter="cpu==1 || cpu==2" 0.000 as/24630 sched:sched_wake_idle_without_ipi(cpu: 1) # # perf trace --max-events 1 --max-stack=32 -e msr:* --filter="msr==IA32_TSC_DEADLINE" 207.000 cc1/19963 msr:write_msr(msr: IA32_TSC_DEADLINE, val: 5442316760822) do_trace_write_msr ([kernel.kallsyms]) do_trace_write_msr ([kernel.kallsyms]) lapic_next_deadline ([kernel.kallsyms]) clockevents_program_event ([kernel.kallsyms]) hrtimer_interrupt ([kernel.kallsyms]) smp_apic_timer_interrupt ([kernel.kallsyms]) apic_timer_interrupt ([kernel.kallsyms]) [0x6ff66c] (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) [0x7047c3] (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) [0x707708] (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) execute_one_pass (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) [0x4f3d37] (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) [0x4f3d49] (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) execute_pass_list (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) cgraph_node::expand (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) [0x2625b4] (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) symbol_table::finalize_compilation_unit (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) [0x5ae8b9] (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) toplev::main (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) main (/usr/lib/gcc-cross/alpha-linux-gnu/8/cc1) [0x26b6a] (/usr/lib/x86_64-linux-gnu/libc-2.29.so) # # perf trace --max-events 8 -e msr:* --filter="msr==IA32_SPEC_CTRL" 0.000 :13281/13281 msr:write_msr(msr: IA32_SPEC_CTRL, val: 6) 0.063 migration/3/25 msr:write_msr(msr: IA32_SPEC_CTRL) 0.217 kworker/u16:1-/4826 msr:write_msr(msr: IA32_SPEC_CTRL) 0.687 rcu_sched/11 msr:write_msr(msr: IA32_SPEC_CTRL) 0.696 :13280/13280 msr:write_msr(msr: IA32_SPEC_CTRL, val: 6) 0.305 :13281/13281 msr:write_msr(msr: IA32_SPEC_CTRL, val: 6) 0.355 :13274/13274 msr:write_msr(msr: IA32_SPEC_CTRL, val: 6) 2.743 kworker/u16:0-/6711 msr:write_msr(msr: IA32_SPEC_CTRL) # # perf trace --max-events 8 --cpu 1 -e msr:* --filter="msr!=IA32_SPEC_CTRL && msr!=IA32_TSC_DEADLINE && msr != FS_BASE" 0.000 mtr-packet/30819 msr:write_msr(msr: 0x830, val: 68719479037) 0.096 :0/0 msr:read_msr(msr: IA32_TSC_ADJUST) 238.925 mtr-packet/30819 msr:write_msr(msr: 0x830, val: 8589936893) 511.010 :0/0 msr:write_msr(msr: 0x830, val: 68719479037) 1005.052 :0/0 msr:read_msr(msr: IA32_TSC_ADJUST) 1235.131 CPU 0/KVM/3750 msr:write_msr(msr: 0x830, val: 4294969595) 1235.195 CPU 0/KVM/3750 msr:read_msr(msr: IA32_SYSENTER_ESP, val: -2199023037952) 1235.201 CPU 0/KVM/3750 msr:read_msr(msr: IA32_APICBASE, val: 4276096000) # - Default to not using libtraceevent and its plugins for beautifying tracepoint arguments, since now we're reusing the strace-like beautifiers.

tools/perf/util/spark.h Test results: The first ones are container based builds of tools/perf with and without libelf support. Where clang is available, it is also used to build perf with/without libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang when clang and its devel libraries are installed. The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure. Get in contact if interested in helping having this in place. Clearlinux is failing when building with libpython, but that is not a perf regression, will try to remove one compiler warning that is causing the problem when building some of the glue code files in the python files, outside perf. # export PERF_TARBALL=http://192.168.124.1/perf/perf-5.4.0-rc2.tar.xz # dm 1 alpine:3.4 : Ok gcc (Alpine 5.3.0) 5.3.0, clang version 3.8.0 (tags/RELEASE_380/final) 2
