perf tools: Makefile: Remove various and sundry cruft 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.

perf tools: Makefile: PYTHON{,_CONFIG} to bandage Python 3 incompatibility Currently, Python 3 is not supported by perf's code; this can cause the build to fail for systems that have Python 3 installed as the default python: python{,-config} The Correct Solution is to write compatibility code so that Python 3 works out-of-the-box. However, users often have an ancillary Python 2 installed: python2{,-config} Therefore, a quick fix is to allow the user to specify those ancillary paths as the python binaries that Makefile should use, thereby avoiding Python 3 altogether; as an added benefit, the Python binaries may be installed in non-standard locations without the need for updating any PATH variable. This commit adds the ability to set PYTHON and/or PYTHON_CONFIG either as environment variables or as make variables on the command line; the paths may be relative, and usually only PYTHON is necessary in order for PYTHON_CONFIG to be defined implicitly. Some rudimentary error checking is performed when the user explicitly specifies a value for any of these variables. In addition, this commit introduces significantly robust makefile infrastructure for working with paths and communicating with the shell; it's currently only used for handling Python, but I hope it will prove useful in refactoring the makefiles.

perf tools: Initial python binding 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.

perf tools: include wrapper for magic.h perf is currently including magic.h directly from the kernel. If the glibc magic.h is also included, this leads to warnings that the constants are redefined. This happens on some systems (e.g. Android). Redefinition errors on Android: In file included from util/util.h:79:0, from util/cache.h:5, from util/abspath.c:1: util/../../../include/linux/magic.h:5:0: error: "AFFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:53:0: note: this is the location of the previous definition util/../../../include/linux/magic.h:19:0: error: "EFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:61:0: note: this is the location of the previous definition util/../../../include/linux/magic.h:26:0: error: "HPFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:67:0: note: this is the location of the previous definition Only two constants from magic.h are used by perf (DEBUGFS_MAGIC and SYSFS_MAGIC). This fix provides a wrapper for magic.h that includes only these constants instead of including the kernel header file directly.

perf tools: Fix sparse CPU numbering related bugs At present, the perf subcommands that do system-wide monitoring (perf stat, perf record and perf top) don't work properly unless the online cpus are numbered 0, 1, ..., N-1. These tools ask for the number of online cpus with sysconf(_SC_NPROCESSORS_ONLN) and then try to create events for cpus 0, 1, ..., N-1. This creates problems for systems where the online cpus are numbered sparsely. For example, a POWER6 system in single-threaded mode (i.e. only running 1 hardware thread per core) will have only even-numbered cpus online. This fixes the problem by reading the /sys/devices/system/cpu/online file to find out which cpus are online. The code that does that is in tools/perf/util/cpumap.[ch], and consists of a read_cpu_map() function that sets up a cpumap[] array and returns the number of online cpus. If /sys/devices/system/cpu/online can't be read or can't be parsed successfully, it falls back to using sysconf to ask how many cpus are online and sets up an identity map in cpumap[]. The perf record, perf stat and perf top code then calls read_cpu_map() in the system-wide monitoring case (instead of sysconf) and uses cpumap[] to get the cpu numbers to pass to perf_event_open.

perf tools: Support for DWARF CFI unwinding on post processing This brings the support for DWARF cfi unwinding on perf post processing. Call frame informations are retrieved and then passed to libunwind that requests memory and register content from the applications. Adding unwind object to handle the user stack backtrace based on the user register values and user stack dump. The unwind object access the libunwind via remote interface and provides to it all the necessary data to unwind the stack. The unwind interface provides following function: unwind__get_entries And callback (specified in above function) to retrieve the backtrace entries: typedef int (*unwind_entry_cb_t)(struct unwind_entry *entry, void *arg); Signed-off-by: Jiri Olsa <jolsa@redhat.com> Original-patch-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: "Frank Ch.

perf tools: Back [vdso] DSO with real data Storing data for VDSO shared object, because we need it for the post unwind processing. The VDSO shared object is same for all process on a running system, so it makes no difference when we store it inside the tracer - perf. When [vdso] map memory is hit, we retrieve [vdso] DSO image and store it into temporary file. During the build-id processing phase, the [vdso] DSO image is stored in build-id db, and build-id reference is made inside perf.data. The build-id vdso file object is called '[vdso]'. We don't use temporary file name which gets removed when record is finished. During report phase the vdso build-id object is treated as any other build-id DSO object. Adding following API for vdso object: bool is_vdso_map(const char *filename) - returns true if the filename matches vdso map name struct dso *vdso__dso_findnew(struct list_head *head) - find/create proper vdso DSO object vdso__exit(void) - removes temporary VDSO image if there's any This change makes backtrace dwarf post unwind possible from [vdso] maps.

perf: add perf-inject builtin Currently, perf 'live mode' writes build-ids at the end of the session, which isn't actually useful for processing live mode events. What would be better would be to have the build-ids sent before any of the samples that reference them, which can be done by processing the event stream and retrieving the build-ids on the first hit. Doing that in perf-record itself, however, is off-limits. This patch introduces perf-inject, which does the same job while leaving perf-record untouched. Normal mode perf still records the build-ids at the end of the session as it should, but for live mode, perf-inject can be injected in between the record and report steps e.g.: perf record -o - ./hackbench 10 | perf inject -v -b | perf report -v -i - perf-inject reads a perf-record event stream and repipes it to stdout. At any point the processing code can inject other events into the event stream - in this case build-ids (-b option) are read and injected as needed into the event stream.

perf: Add perf probe subcommand, a kprobe-event setup helper Add perf probe subcommand that implements a kprobe-event setup helper to the perf command. This allows user to define kprobe events using C expressions (C line numbers, C function names, and C local variables). Usage ----- perf probe [<options>] -P 'PROBEDEF' [-P 'PROBEDEF' ...] -k, --vmlinux <file> vmlinux/module pathname -P, --probe <p|r:[GRP/]NAME FUNC[+OFFS][@SRC]|@SRC:LINE [ARG ...]> probe point definition, where p: kprobe probe r: kretprobe probe GRP: Group name (optional) NAME: Event name FUNC: Function name OFFS: Offset from function entry (in byte) SRC: Source code path LINE: Line number ARG: Probe argument (local variable name or kprobe-tracer argument format is supported.) Changes in v4: - Add _GNU_SOURCE macro for strndup(). Changes in v3: - Remove -r option because perf always be used for online kernel. - Check malloc/calloc results. Changes in v2: - Check synthesized string length. - Rename perf kprobe to perf probe. - Use spaces for separator and update usage comment. - Check error paths in parse_probepoint(). - Check optimized-out variables.

perf tools: Do not include PERF-VERSION-FILE to Makefile When make runs it tries to update the Makefile rules by reading all of included Makefiles. During the perf build it checks PERF-VERSION-FILE to get the current version number. But it triggers Makefile update so that make runs again with the update Makefile and, in turn, users will see duplicate CHK message on the second path. Running make with -d option for debugging tells me this: GNU Make 3.82 Built for x86_64-redhat-linux-gnu Copyright (C) 2010 Free Software Foundation, Inc.

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.

perf tools: Makefile: PYTHON{,_CONFIG} to bandage Python 3 incompatibility Currently, Python 3 is not supported by perf's code; this can cause the build to fail for systems that have Python 3 installed as the default python: python{,-config} The Correct Solution is to write compatibility code so that Python 3 works out-of-the-box. However, users often have an ancillary Python 2 installed: python2{,-config} Therefore, a quick fix is to allow the user to specify those ancillary paths as the python binaries that Makefile should use, thereby avoiding Python 3 altogether; as an added benefit, the Python binaries may be installed in non-standard locations without the need for updating any PATH variable. This commit adds the ability to set PYTHON and/or PYTHON_CONFIG either as environment variables or as make variables on the command line; the paths may be relative, and usually only PYTHON is necessary in order for PYTHON_CONFIG to be defined implicitly. Some rudimentary error checking is performed when the user explicitly specifies a value for any of these variables. In addition, this commit introduces significantly robust makefile infrastructure for working with paths and communicating with the shell; it's currently only used for handling Python, but I hope it will prove useful in refactoring the makefiles. Thanks to: Raghavendra D Prabhu <rprabhu@wnohang.net> for motivating this patch.
