We cannot limit processing stacks from the current value of the sysctl, as we may be processing perf.data files, possibly from other machines. Instead use the old PERF_MAX_STACK_DEPTH, the sysctl default, that can be overriden using --max-stack or equivalent.

There is an upper limit to what tooling considers a valid callchain, and it was tied to the hardcoded value in the kernel, PERF_MAX_STACK_DEPTH (127), now that this can be tuned via a sysctl, make it read it and use that as the upper limit, falling back to PERF_MAX_STACK_DEPTH for kernels where this sysctl isn't present.

To reduce the chances we'll overflow the mmap buffer, manual fine tuning trumps this.

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.

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]

Often, adding `-m 10M` to the `perf trace` invocation is enough. This feature is also available in strace when built with libunwind via `strace -k`. Performance wise, this solution is much better: $ time find path/to/linux &> /dev/null real 0m0.051s user 0m0.013s sys 0m0.037s $ time perf trace -m 800M --call-graph dwarf find path/to/linux &> /dev/null real 0m2.624s user 0m1.203s sys 0m1.333s $ time strace -k find path/to/linux &> /dev/null real 0m35.398s user 0m10.403s sys 0m23.173s Note that it is currently not possible to configure the print output. Adding such a feature, similar to what is available in `perf script` via its `--fields` knob can be added later on.

This comes from the desire of having -e/--expr to have the same meaning as for 'strace', while other perf tools use it for --event, which 'trace' honours, i.e. all perf tools have --event in common, but trace uses -e for strace's --expr.

When tracing in X we get event loops due to the tracing activity, i.e. updates to a gnome-terminal that generate syscalls for X.org, etc. To get a more useful view of what is happening, syscall wise, system wide, we need to filter those, like in: # ps ax|egrep '981|2296|1519' | grep -v egrep 981 tty1 Ss+ 5:40 /usr/bin/Xorg :0 -background none ... 1519 ?

Initially it tries to find a probe:vfs_getname that should be setup with: perf probe 'vfs_getname=getname_flags:65 pathname=result->name:string' or with slight changes to cope with code flux in the getname_flags code. In the future, if a "vfs:getname" tracepoint becomes available, then it will be preferred. This is not strictly required and more expensive method of reading the /proc/pid/fd/ symlink will be used when the fd->path array entry is not populated by a previous vfs_getname + open syscall ret sequence. As with any other 'perf probe' probe the setup must be done just once and the probe will be left inactive, waiting for users, be it 'perf trace' of any other tool.

Adding possibility to specify mmap size via -m/--mmap-pages by appending unit size character (B/K/M/G) to the number, like: $ perf record -m 8K ls $ perf record -m 2M ls The size is rounded up appropriately to follow perf mmap restrictions.

Initially should look loosely like the venerable 'strace' tool, but using the infrastructure in the perf tools to allow tracing extra targets: [acme@sandy linux]$ perf trace --hell Error: unknown option `hell' usage: perf trace <PID> -p, --pid <pid> trace events on existing process id --tid <tid> trace events on existing thread id --all-cpus system-wide collection from all CPUs --cpu <cpu> list of cpus to monitor --no-inherit child tasks do not inherit counters --mmap-pages <n> number of mmap data pages --uid <user> user to profile [acme@sandy linux]$ Those should have the same semantics as when using with 'perf record'. It gets stuck sometimes, but hey, it works sometimes too! In time it should support perf.data based workloads, i.e. it should have a: -o filename Command line option that will produce a perf.data file that can then be used with 'perf trace' or any of the other perf tools (script, report, etc). It will also eventually have the set of functionalities described in the previous 'trace' prototype by Thomas Gleixner: "Announcing a new utility: 'trace'" http://lwn.net/Articles/415728/ Also planned is to have some of the features suggested in the comments of that LWN article.

'perf trace -s list' prints a list of the supported scripting languages. One problem with it is that it falls through and prints the trace as well. The use of 'list' for this also makes it easy to confuse with 'perf trace -l', used for listing available scripts. So change 'perf trace -s list' to 'perf trace -s lang' and fixes the fall-through problem.
