2019-03-28perf scripts python: exported-sql-viewer.py: Fix python3 supportAdrian Hunter1-4/+13
Unlike python2, python3 strings are not compatible with byte strings. That results in disassembly not working for the branches reports. Fixup those places overlooked in the port to python3.

2019-02-06perf thread-stack: Represent jmps to the start of a different symbolAdrian Hunter2-2/+2
The compiler might optimize a call/ret combination by making it a jmp. However the thread-stack does not presently cater for that, so that such control flow is not visible in the call graph. Make it visible by recording on the stack a branch to the start of a different symbol. Note, that means when a ret pops the stack, all jmps must be popped off first. Example: $ cat jmp-to-fn.c __attribute__((noinline)) int bar(void) { return -1; } __attribute__((noinline)) int foo(void) { return bar() + 1; } int main() { return foo(); } $ gcc -ggdb3 -Wall -Wextra -O2 -o jmp-to-fn jmp-to-fn.c $ objdump -d jmp-to-fn <SNIP> 0000000000001040 <main>: 1040: 31 c0 xor %eax,%eax 1042: e9 09 01 00 00 jmpq 1150 <foo> <SNIP> 0000000000001140 <bar>: 1140: b8 ff ff ff ff mov $0xffffffff,%eax 1145: c3 retq <SNIP> 0000000000001150 <foo>: 1150: 31 c0 xor %eax,%eax 1152: e8 e9 ff ff ff callq 1140 <bar> 1157: 83 c0 01 add $0x1,%eax 115a: c3 retq <SNIP> $ perf record -o jmp-to-fn.perf.data -e intel_pt/cyc/u ./jmp-to-fn [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0,017 MB jmp-to-fn.perf.data ] $ perf script -i jmp-to-fn.perf.data --itrace=be -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py jmp-to-fn.db branches calls 2019-01-08 13:24:58.783069 Creating database... 2019-01-08 13:24:58.794650 Writing records... 2019-01-08 13:24:59.008050 Adding indexes 2019-01-08 13:24:59.015802 Done $ ~/libexec/perf-core/scripts/python/exported-sql-viewer.py jmp-to-fn.db Before: main -> bar After: main -> foo -> bar Committer testing: Install the python2-pyside package, then select these menu options on the GUI: "Reports" "Context sensitive callgraphs" Then go on expanding the symbols, to get, full picture when doing this on a fedora:29 with gcc version 8.2.1 20181215 (Red Hat 8.2.1-6) (GCC): jmp-to-fn PID:TID _start (ld-2.28.so) __libc_start_main main foo bar To verify that indeed, this fixes the problem.

2019-01-25perf script python: Remove explicit shebang from Python scriptsTony Jones3-4/+0
The scripts in scripts/python are intended to be run from 'perf script' and the Python version used is dictated by how perf was built (PYTHON=). Also most distros follow pep-0394 which recommends that /usr/bin/python refer to Python2 and so may not exist on the system (if PYTHON=python3). - Remove the explicit shebang - Install the scripts as mode 644 Signed-off-by: Tony Jones <tonyj@suse.de> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jonathan Corbet <corbet@lwn.net> Cc: Ravi Bangoria <ravi.bangoria@linux.ibm.com> Cc: Seeteena Thoufeek <s1seetee@linux.vnet.ibm.com> Link: http://lkml.kernel.org/r/20190124005229.16146-6-tonyj@suse.de Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

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>

Displaying all the database tables can help make the database easier to understand.

CREATE VIEW threads_view AS SELECT id,machine_id,(SELECT host_or_guest FROM machines_view WHERE id = machine_id) AS host_or_guest,process_id,pid,tid FROM threads Humm, nope, just one of the cells got copied, even with everything selected :-) Anyway, works as advertised, useful for perusing the data.
