2016-04-18perf report: Use callchain_param.enabled instead of tool specific knobArnaldo Carvalho de Melo1-5/+6
We have callchain_param.enabled, so no need to have something just for 'perf report' to do the same thing.

2016-04-18perf callchain: Set callchain_param.enabled when parsing --call-graphArnaldo Carvalho de Melo1-0/+2
Trying to move in the direction of using callchain_param for all callchain parameters, eventually ditching them from symbol_conf.

2016-04-15perf evlist: Expose perf_event_mlock_kb_in_pages() helperArnaldo Carvalho de Melo2-17/+27
When the user doesn't set --mmap-pages, perf_evlist__mmap() will do it by reading the maximum possible for a non-root user from the /proc/sys/kernel/perf_event_mlock_kb file. Expose that function so that 'perf trace' can, for root users, to bump mmap-pages to a higher value for root, based on the contents of this proc file.

2016-04-15perf trace: Make --(min,max}-stack imply "--call-graph dwarf"Arnaldo Carvalho de Melo2-1/+18
If one uses: # perf trace --min-stack 16 Then it implicitly means that callgraphs should be enabled, and the best option in terms of widespread availability is "dwarf". Further work needed to choose a better alternative, LBR, in capable systems.

2016-04-15perf trace: Introduce --min-stack filterArnaldo Carvalho de Melo2-18/+41
Counterpart to --max-stack, to help focusing on deeply nested calls. Can be combined with --duration, etc. E.g.: System wide syscall tracing looking for call stacks longer than 66: # trace --mmap-pages 32768 --filter-pid 2711 --call-graph dwarf,16384 --min-stack 66 Or more compactly: # trace -m 32768 --filt 2711 --call dwarf,16384 --min-st 66 363.027 ( 0.002 ms): gnome-shell/2287 poll(ufds: 0x7ffc5ea24230, nfds: 1, timeout_msecs: 4294967295 ) = 1 [0xf6fdd]

2016-04-15perf trace: Do not print interrupted syscalls when using --durationArnaldo Carvalho de Melo1-1/+1
With multiple threads, e.g. a system wide trace session, and one syscall is midway in a thread and another thread starts another syscall we must print the start of the interrupted syscall followed by ..., but that can't be done that way when we use the --duration filter, as we have to wait for the syscall exit to calculate the duration and decide if it should be filtered, so we have to disable the interrupted logic and only print at syscall exit, duh.

2016-04-13perf trace: Support callchains for --event tooArnaldo Carvalho de Melo1-15/+26
We already were able to ask for callchains for a specific event: # trace -e nanosleep --call dwarf --event sched:sched_switch/call-graph=fp/ usleep 1 This would enable tracing just the "nanosleep" syscall, with callchains at syscall exit and would ask the kernel for frame pointer callchains to be enabled for the "sched:sched_switch" tracepoint event, its just that we were not resolving the callchain and printing it in 'perf trace', do it: # trace -e nanosleep --call dwarf --event sched:sched_switch/call-graph=fp/ usleep 1 0.425 ( 0.013 ms): usleep/6718 nanosleep(rqtp: 0x7ffcc1d16e20) ... 0.425 ( ): sched:sched_switch:usleep:6718 [120] S ==> swapper/2:0 [120]) __schedule+0xfe200402 ([kernel.kallsyms]) schedule+0xfe200035 ([kernel.kallsyms]) do_nanosleep+0xfe20006f ([kernel.kallsyms]) hrtimer_nanosleep+0xfe2000dc ([kernel.kallsyms]) sys_nanosleep+0xfe20007a ([kernel.kallsyms]) do_syscall_64+0xfe200062 ([kernel.kallsyms]) return_from_SYSCALL_64+0xfe200000 ([kernel.kallsyms]) __nanosleep+0xffff008b8cbe2010 (/usr/lib64/libc-2.22.so) 0.486 ( 0.073 ms): usleep/6718 ...

Now it is just a matter of calling any perf tool, such as 'trace', with a C source file that references the __bpf_stdout__ output channel and that channel will be created and connected to the script: # trace -e nanosleep --event test_bpf_stdout.c usleep 1 0.013 ( 0.013 ms): usleep/2818 nanosleep(rqtp: 0x7ffcead45f40 ) ... 0.013 ( ): __bpf_stdout__:Raise a BPF event!..) 0.015 ( ): perf_bpf_probe:func_begin:(ffffffff81112460)) 0.261 ( ): __bpf_stdout__:Raise a BPF event!..) 0.262 ( ): perf_bpf_probe:func_end:(ffffffff81112460 <- ffffffff81003d92)) 0.264 ( 0.264 ms): usleep/2818 ... [continued]: nanosleep()) = 0 # Further work is needed to reduce the number of lines in a perf bpf C source file, this being the part where we greatly reduce the command line setup (Wang Nan) - 'perf trace' now supports callchains, with 'trace --call-graph dwarf' using libunwind, just like 'perf top', to ask the kernel for stack dumps for CFI processing. This reduces the overhead by asking just for userspace callchains and also only for the syscall exit tracepoint (raw_syscalls:sys_exit) (Milian Wolff, Arnaldo Carvalho de Melo) Try it with, for instance: # perf trace --call dwarf ping 127.0.0.1 An excerpt of a system wide 'perf trace --call dwarf" session is at: https://fedorapeople.org/~acme/perf/perf-trace--call-graph-dwarf--all-cpus.txt You may need to bump the number of mmap pages, using -m/--mmap-pages, but on a Broadwell machine the defaults allowed system wide tracing to work without losing that many records, experiment with just some syscalls, like: # perf trace --call dwarf -e nanosleep,futex All the targets available for 'perf record', 'perf top' (--pid, --tid, --cpu, etc) should work. Also --duration may be interesting to try. To get filenames from in various syscalls pointer args (open, ettc), add this to the mix: # perf probe 'vfs_getname=getname_flags:72 pathname=filename:string' Making this work is next in line: # trace --call dwarf --ev sched:sched_switch/call-graph=fp/ usleep 1 I.e. honouring per-tracepoint callchains in 'perf trace' in addition to in raw_syscalls:sys_exit.
