And it is being successfull only when running alone, probably because there are some tests that add the vfs_getname probe that gets used by 'perf trace' and alter how it does syscall arg pathname resolution. This should be removed or made a fallback to the preferred BPF mode of getting syscall parameters, but till then, run this in exclusive mode. For reference, here are some of the tests that run close to this one: 127: perf record offcpu profiling tests : Ok 128: perf all PMU test : Ok 129: perf stat --bpf-counters test : Ok 130: Check Arm CoreSight trace data recording and synthesized samples: Skip 131: Check Arm CoreSight disassembly script completes without errors : Skip 132: Check Arm SPE trace data recording and synthesized samples : Skip 133: Test data symbol : Ok 134: Miscellaneous Intel PT testing : Skip 135: test Intel TPEBS counting mode : Skip 136: perf script task-analyzer tests : Ok 137: Check open filename arg using perf trace + vfs_getname : Ok 138: perf trace summary : Ok Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Howard Chu <howardchu95@gmail.com> Cc: Ian Rogers <irogers@google.com> Cc: James Clark <james.clark@linaro.org> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/aC-hHTgArwlF_zu9@x1 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
