2018-10-24selftests/ftrace: Use loopback address instead of localhostMasami Hiramatsu

2018-10-24selftests/ftrace: Fix to test kprobe $comm arg only if availableMasami Hiramatsu
Test $comm in kprobe-event argument syntax testcase only if it is supported on the kernel because $comm has been introduced 4.8 kernel. So on older stable kernel, it should be skipped. Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org>
2018-10-24selftests/ftrace: Remove unneeded per-test init/cleanup ftraceMasami Hiramatsu
Since ftracetest framework calls initialize_ftrace() right before each test and after all tests, we don't need to init/cleanup ftrace for each test case. Just remove such unneeded init/cleanup code because it can increase logfile size. Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org>
2018-10-24selftests/ftrace: Cleanup ftrace after running testMasami Hiramatsu
Cleanup ftrace by initialize_ftrace() after running all test cases. This means we also don't need cleanup ftrace on each test case, except for some special options. Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org>
2018-10-24selftests/ftrace: Add SPDX License Identifier to templateMasami Hiramatsu

2018-10-24selftests/ftrace: Add --console hidden optionMasami Hiramatsu
Add --console hidden option for debug test cases. This option allows to put "sh" or something else when the test case hits a bug. For example, if you find a testcase which doesn't pass, you can insert sh for interactive debug as below ----- #!/bin/sh # description: sample test case good-command suspicious-wrong-command sh # <- add this for interactive debug ----- Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org>

2018-10-24perf script: Make itrace script default to all callsAndi Kleen
By default 'perf script' for itrace outputs sampled instructions or branches. In my experience this is confusing to users because it's hard to correlate with real program behavior. The sampling makes sense for tools like 'perf report' that actually sample to reduce the run time, but run time is normally not a problem for 'perf script'. It's better to give an accurate representation of the program flow. Default 'perf script' to output all calls for itrace. That's a much saner default.

2018-10-23perf scripts python: exported-sql-viewer.py: Add All branches reportAdrian Hunter
Add a report to display branches in a similar fashion to perf script. The main purpose of this report is to display disassembly, however, presently, the only supported disassembler is Intel XED, and additionally the object code must be present in perf build ID cache. To use Intel XED, libxed.so must be present. To build and install libxed.so: git clone https://github.com/intelxed/mbuild.git mbuild git clone https://github.com/intelxed/xed cd xed ./mfile.py --share sudo ./mfile.py --prefix=/usr/local install sudo ldconfig Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/r/20181023075949.18920-1-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

class TreeItem represents items at all levels of the call-graph tree. However, not all the levels represent the same data i.e. the top-level is comms, the next level is threads, and subsequent levels are functions. Consequently it is simpler to have separate classes for different levels with commonality in a base class. Refactor TreeItem class accordingly.
