perf trace: Use the fd->name beautifier as default for "fd" args · b6565c90

由 Arnaldo Carvalho de Melo 提交于 5月 23, 2016

Noticed when the 'setsockopt' 'fd' arg wasn't being formatted via
the SCA_FD beautifier, so just remove the setting of "fd" args to
SCA_FD and do it when reading the syscall info, like we do for
args of type "pid_t", i.e. "fd" as the name should be enough as
the decision to use the SFA_FD beautifier. For odd cases we can
just do it explicitely.

perf tools: Fix usage of max_stack sysctl · fe176085

由 Arnaldo Carvalho de Melo 提交于 5月 19, 2016

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.

perf trace: Do not print raw args list for syscalls with no args · 4c4d6e51

由 Arnaldo Carvalho de Melo 提交于 5月 05, 2016

The test to check if the arg format had been read from the
syscall:sys_enter_name/format file was looking at the list of non-commom
fields, and if that is empty, it would think it had failed to read it,
because it doesn't exist, for instance, for the clone() syscall.

So instead before dumping the raw syscall args list check
IS_ERR(sc->tp_format), if that is true, then an attempt was made to read
the format file and failed, in which case dump the raw arg list values.

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.

The variable is initialized and then conditionally set to a different

perf trace: Make --(min,max}-stack imply "--call-graph dwarf" · 05614993

由 Arnaldo Carvalho de Melo 提交于 4月 15, 2016

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

  Or more compactly:

  # trace -m 32768 --filt 2711 --call dwarf,16384 --min-st 66

perf trace: Do not print interrupted syscalls when using --duration · e519bd9a

由 Arnaldo Carvalho de Melo 提交于 4月 15, 2016

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.

This way the print routine merely does printing, not requiring access to
the resolving machinery, which helps disentangling the object files and
easing creating subsets with a limited functionality set.

perf trace: Add seccomp beautifier related defines for older systems · 6fb35b95

由 Arnaldo Carvalho de Melo 提交于 4月 13, 2016

Were the detached tarball (make perf-tar-src-pkg) build was failing because
those definitions aren't available in the system headers.

On RHEL7, for instance:

  builtin-trace.c: In function ‘syscall_arg__scnprintf_seccomp_op’:
  builtin-trace.c:1069:7: error: ‘SECCOMP_SET_MODE_STRICT’ undeclared (first use in this function)
    P_SECCOMP_SET_MODE_OP(STRICT);
         ^
  builtin-trace.c:1069:7: note: each undeclared identifier is reported only once for each function it appears in
  builtin-trace.c:1070:7: error: ‘SECCOMP_SET_MODE_FILTER’ undeclared (first use in this function)
    P_SECCOMP_SET_MODE_OP(FILTER);
         ^
  builtin-trace.c: In function ‘syscall_arg__scnprintf_seccomp_flags’:
  builtin-trace.c:1091:14: error: ‘SECCOMP_FILTER_FLAG_TSYNC’ undeclared (first use in this function)
    P_FLAG(TSYNC);
                ^
