2011-02-18perf tools: Makefile: Remove various and sundry cruftMichael Witten
This commit squashes several commits that remove: unnecessary uname calls `sh -c' BUILT_INS and QUIET_BUILT_IN They have no effect, and the `fixup-builtins' and `check-builtins.sh' scripts don't even exist. RUNTIME_PREFIX It's currently never anything but unset, and it's apparently only meaningful when Microsoft Windows is the operating system (according to the source for git). TEST_PROGRAMS EXTRA_PROGRAMS unused SHELL_PATH_SQ portions unused test for V=2 useless exports Only when `V' is undefined (that is, only when the value of `V' is empty) is `export V' performed, which just has the effect of placing the empty-valued variable `V' in the environment. The only other script to make use of `V' is `Documentation/Makefile', which only checks whether `V' is undefined (that is, whether the value of `V' is empty); hence, the `export V' has no effect whatsoever. Similarly, `export QUIET_GEN' is useless because it will only have a non-empty value when `V' has an empty-value, and when `V' has an empty-value, `QUIET_GEN' is always explicitly set in every script in which it is used. `DESTDIR' is only ever defined by the user via the environment or the command line, both of which are automatically exported to sub-make processes. Furthermore, no non-make sub-scripts make use of `DESTDIR' as an environment variable. No other scripts use `perfexec_instdir'. unused QUIET_SUBDIR{0,1} TAR and RPMBUILD PTHREAD_LIBS Maintainer's dist rules and commands distclean target Test suite coverage testing PRINT_DIR and NO_SUBDIR `configure' target NO_CURL @@PERF_VERSION@@ substitution Without the sed command, all of the rule's commands can be reduced to a single line that copies a file and sets the permissions properly in the process. `make test' echo line template_instdir PERF-BUILD-OPTIONS double-colon rules The use of double-colon rules seems misguided or vestigial git.

2011-02-16perf tool: Add cgroup supportStephane Eranian
This patch adds the ability to filter monitoring based on container groups (cgroups) for both perf stat and perf record. It is possible to monitor multiple cgroup in parallel. There is one cgroup per event. The cgroups to monitor are passed via a new -G option followed by a comma separated list of cgroup names. The cgroup filesystem has to be mounted. Given a cgroup name, the perf tool finds the corresponding directory in the cgroup filesystem and opens it. It then passes that file descriptor to the kernel. Example: $ perf stat -B -a -e cycles:u,cycles:u,cycles:u -G test1,,test2 -- sleep 1 Performance counter stats for 'sleep 1': 2,368,667,414 cycles test1 2,369,661,459 cycles <not counted> cycles test2 1.001856890 seconds time elapsed Signed-off-by: Stephane Eranian <eranian@google.com> Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> LKML-Reference: <4d590290.825bdf0a.7d0a.4890@mx.google.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2011-01-30perf tools: Initial python bindingArnaldo Carvalho de Melo
First clarifying that this kind of binding is not a replacement or an equivalent to the 'perf script' way of using python with perf. The 'perf script' way is to process events and look at a given script for some python function that matches the events to pass each event for processing. This is a python module, i.e. everything is driven from the python script, that merely uses "import perf" or "from perf import". perf script is focused on tracepoints, this binding is focused on profiling as an initial target. More work is needed to make available tracepoint specific variables as event variables accessible via this binding. There is one example of such usage model, in tools/perf/python/twatch.py, a tool to watch "cycles" events together with task (fork, exit) and comm perf events. For now, due to me not being able to grok how python distutils cope with building C extensions outside the sources dir the install target just builds it, I'm using it as: [root@emilia linux]# export PYTHONPATH=~acme/git/build/perf/lib.linux-x86_64-2.6/ [root@emilia linux]# tools/perf/python/twatch.py cpu: 4, pid: 30126, tid: 30126 { type: mmap, pid: 30126, tid: 30126, start: 0x4, length: 0x82e9ca03, offset: 0, filename: } cpu: 6, pid: 47, tid: 47 { type: mmap, pid: 47, tid: 47, start: 0x6, length: 0xbef87c36, offset: 0, filename: } cpu: 1, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0x1, length: 0x775d1904, offset: 0, filename: } cpu: 7, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0x7, length: 0xc750aeb6, offset: 0, filename: } cpu: 5, pid: 2255, tid: 2255 { type: mmap, pid: 2255, tid: 2255, start: 0x5, length: 0x76669635, offset: 0, filename: } cpu: 0, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0, length: 0x6422ef6b, offset: 0, filename: } cpu: 2, pid: 2255, tid: 2255 { type: mmap, pid: 2255, tid: 2255, start: 0x2, length: 0xe078757a, offset: 0, filename: } cpu: 1, pid: 5769, tid: 5769 { type: fork, pid: 30127, ppid: 5769, tid: 30127, ptid: 5769, time: 103893991270534} cpu: 6, pid: 30127, tid: 30127 { type: comm, pid: 30127, tid: 30127, comm: ls } cpu: 6, pid: 30127, tid: 30127 { type: exit, pid: 30127, ppid: 30127, tid: 30127, ptid: 30127, time: 103893993273024} The first 8 mmap events in this 8 way machine are a mistery that is still being investigated. More of the tools/perf/util/ APIs will be exposed via this python binding as the need arises. For now the focus is on creating events and processing them, symbol resolution is an obvious next step, with tracepoint variables as a close second step.

2011-01-28perf tools: Add strfilter for general purpose string filterMasami Hiramatsu
Add strfilter for general purpose string filter. Every filter rules are descrived by glob matching pattern and '!' prefix which means Logical NOT. A strfilter consists of those filter rules connected with '&' and '|'. A set of rules can be folded by using '(' and ')'. It also accepts spaces around rules and those operators. Format: <rule> ::= <glob-exp> | "!" <rule> | <rule> <op> <rule> | "(" <rule> ")" <op> ::= "&" | "|" e.g.: "(add* | del*) & *timer" filter rules pass strings which start with add or del and end with timer. This will be used by perf probe --filter. Changes in V2: - Fix to check result of strdup() and strfilter__alloc(). - Encapsulate and simplify interfaces as like regex(3).

2010-12-07perf makefile: Allow strong and weak functions in LIB_OBJSIan Munsie
When we build perf we place all of the .o files from the library files (util, arch/x/util, etc) into libperf.a which is then linked into perf. The problem is that the linker will by default only consider .o files within the .a archive if they are necessary to satisfy an unresolved symbol. As weak functions are not unresolved, it will not consider a .o file from the archive containing the strong versions of weak functions unless it requires it for another reason. This patch adds the --whole-archive flags to the linker when passing in the libperf.a file to ensure that it will consider every .o file in the archive, not just what it believes that it needs. The end result is that weak functions can now be overridden by strong variants of them in the libperf.a file.

2010-11-19perf tools: Remove hardcoded include paths for elfutilsRobert Morell
This change removes the use of hardcoded absolute "/usr/include/elfutils" paths from the perf build. The problem with hardcoded paths is that it prevents them from being overridden by $prefix or by -I in CFLAGS (e.g., for cross-compiling purposes). Instead, just include the "elfutils/" subdirectory as a relative path when files are needed from that directory. Tested by building perf: - Cross-compiled for ARM on x86_64 - Built natively on x86_64 - Built on x86_64 with /usr/include/elfutils moved to another location and manually included in CFLAGS Acked-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> Cc: Ingo Molnar <mingo@elte.hu> Cc: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> LKML-Reference: <1289945793-31441-1-git-send-email-rmorell@nvidia.com> Signed-off-by: Robert Morell <rmorell@nvidia.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Fix it by using $(OUTPUT) on these locations. Also check that $(OUTPUT) actually exists, just like the top level kernel Makefile does. Otherwise the failure message emitted is completely misleading.

2010-06-09perf tools: Reorganize the Makefile feature testsArnaldo Carvalho de Melo
Moving the tests to a separate file, feature-tests.mak and using a try-cc function similar to the try-run in Kbuild. This also makes the output more quiet as we can stop using the INTERMEDIATE target to remove the .perf.dev.null file needed for some gcc versions where /dev/null can't be used as the output file name. As the tests get shorter by uninlining the source code used to test for features, we can more properly use identation. The feature tests itself can be made more clear and reused, like when trying to see what is needed to have bfd_demangle. We also get a bit closer to reusing scripts/Kbuild.include, reducing the distance from the kernel build system.

2010-05-11perf report: Librarize the annotation code and use it in the newt browserArnaldo Carvalho de Melo
Now we don't anymore use popen to run 'perf annotate' for the selected symbol, instead we collect per address samplings when processing samples in 'perf report' if we're using the newt browser, then we use this data directly to do annotation. Done this way we can actually traverse the objdump_line objects directly, matching the addresses to the collected samples and colouring them appropriately using lower level slang routines. The new ui_browser class will be reused for the main, callchain aware, histogram browser, when it will be made generic and don't assume that the objects are always instances of the objdump_line class maintained using list_heads.

For Fedora, I want to force perf to link against libiberty.a for cplus_demangle, rather than libbfd.a for bfd_demangle due to licensing insanity on binutils. (libiberty is LGPL2, libbfd is GPL3.) If we just rely on autodetection, we'll end up with libbfd linked against us, since they're both in binutils-static in the buildroot.
