perf tools: Fix build error on read only source. Parts of the build process were generating files outside the specified O= directory, causing the build to fail on systems where the sources are in a read only file system. 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.

perf: Enable more compiler warnings Related to a shadowed variable bug fix Valdis Kletnieks noticed that perf does not get built with -Wshadow, which could have helped us avoid the bug. So enable -Wshadow and also enable the following warnings on perf builds, in addition to the already enabled -Wall -Wextra -std=gnu99 warnings: -Wcast-align -Wformat=2 -Wshadow -Winit-self -Wpacked -Wredundant-decls -Wstack-protector -Wstrict-aliasing=3 -Wswitch-default -Wswitch-enum -Wno-system-headers -Wundef -Wvolatile-register-var -Wwrite-strings -Wbad-function-cast -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wold-style-definition -Wstrict-prototypes -Wdeclaration-after-statement And change/fix the perf code to build cleanly under GCC 4.3.2. The list of warnings enablement is rather arbitrary: it's based on my (quick) reading of the GCC manpages and trying them on perf. I categorized the warnings based on individually enabling them and looking whether they trigger something in the perf build. If i liked those warnings (i.e. if they trigger for something that arguably could be improved) i enabled the warning. If the warnings seemed to come from language laywers spamming the build with tons of nuisance warnings i generally kept them off. Most of the sign conversion related warnings were in this category. (A second patch enabling some of the sign warnings might be welcome - sign bugs can be nasty.) I also kept warnings that seem to make sense from their manpage description and which produced no actual warnings on our code base. These warnings might still be turned off if they end up being a nuisance. I also left out a few warnings that are not supported in older compilers. [ Note that these changes might break the build on older compilers i did not test, or on non-x86 architectures that produce different warnings, so more testing would be welcome. ] Reported-by: Valdis.Kletnieks@vt.edu Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> LKML-Reference: <new-submission> Signed-off-by: Ingo Molnar <mingo@elte.hu>

perf tools: Reorganize the Makefile feature tests 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.

perf: Do the big rename: Performance Counters -> Performance Events Bye-bye Performance Counters, welcome Performance Events! In the past few months the perfcounters subsystem has grown out its initial role of counting hardware events, and has become (and is becoming) a much broader generic event enumeration, reporting, logging, monitoring, analysis facility. Naming its core object 'perf_counter' and naming the subsystem 'perfcounters' has become more and more of a misnomer. With pending code like hw-breakpoints support the 'counter' name is less and less appropriate. All in one, we've decided to rename the subsystem to 'performance events' and to propagate this rename through all fields, variables and API names. (in an ABI compatible fashion) The word 'event' is also a bit shorter than 'counter' - which makes it slightly more convenient to write/handle as well. Thanks goes to Stephane Eranian who first observed this misnomer and suggested a rename. User-space tooling and ABI compatibility is not affected - this patch should be function-invariant. (Also, defconfigs were not touched to keep the size down.) This patch has been generated via the following script: FILES=$(find * -type f | grep -vE 'oprofile|[^K]config') sed -i \ -e 's/PERF_EVENT_/PERF_RECORD_/g' \ -e 's/PERF_COUNTER/PERF_EVENT/g' \ -e 's/perf_counter/perf_event/g' \ -e 's/nb_counters/nb_events/g' \ -e 's/swcounter/swevent/g' \ -e 's/tpcounter_event/tp_event/g' \ $FILES for N in $(find . -name perf_counter.[ch]); do M=$(echo $N | sed 's/perf_counter/perf_event/g') mv $N $M done FILES=$(find . -name perf_event.*) sed -i \ -e 's/COUNTER_MASK/REG_MASK/g' \ -e 's/COUNTER/EVENT/g' \ -e 's/\<event\>/event_id/g' \ -e 's/counter/event/g' \ -e 's/Counter/Event/g' \ $FILES ... to keep it as correct as possible. This script can also be used by anyone who has pending perfcounters patches - it converts a Linux kernel tree over to the new naming. We tried to time this change to the point in time where the amount of pending patches is the smallest: the end of the merge window. Namespace clashes were fixed up in a preparatory patch - and some stylistic fallout will be fixed up in a subsequent patch. ( NOTE: 'counters' are still the proper terminology when we deal with hardware registers - and these sed scripts are a bit over-eager in renaming them. I've undone some of that, but in case there's something left where 'counter' would be better than 'event' we can undo that on an individual basis instead of touching an otherwise nicely automated patch. ) Suggested-by: Stephane Eranian <eranian@google.com> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Paul Mackerras <paulus@samba.org> Reviewed-by: Arjan van de Ven <arjan@linux.intel.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: David Howells <dhowells@redhat.com> Cc: Kyle McMartin <kyle@mcmartin.ca> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "David S.

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 test: Initial regression testing command First an example with the first internal test: [acme@doppio linux-2.6-tip]$ perf test 1: vmlinux symtab matches kallsyms: Ok So it run just one test, that is "vmlinux symtab matches kallsyms", and it was successful. If we run it in verbose mode, we'll see details about errors and extra warnings for non-fatal problems: [acme@doppio linux-2.6-tip]$ perf test -v 1: vmlinux symtab matches kallsyms: --- start --- Looking at the vmlinux_path (5 entries long) No build_id in vmlinux, ignoring it No build_id in /boot/vmlinux, ignoring it No build_id in /boot/vmlinux-2.6.34-rc4-tip+, ignoring it Using /lib/modules/2.6.34-rc4-tip+/build/vmlinux for symbols Maps only in vmlinux: ffffffff81cb81b1-ffffffff81e1149b 0 [kernel].init.text ffffffff81e1149c-ffffffff9fffffff 0 [kernel].exit.text ffffffffff600000-ffffffffff6000ff 0 [kernel].vsyscall_0 ffffffffff600100-ffffffffff6003ff 0 [kernel].vsyscall_fn ffffffffff600400-ffffffffff6007ff 0 [kernel].vsyscall_1 ffffffffff600800-ffffffffffffffff 0 [kernel].vsyscall_2 Maps in vmlinux with a different name in kallsyms: ffffffffff600000-ffffffffff6000ff 0 [kernel].vsyscall_0 in kallsyms as [kernel].0 ffffffffff600100-ffffffffff6003ff 0 [kernel].vsyscall_fn in kallsyms as: *ffffffffff600100-ffffffffff60012f 0 [kernel].2 ffffffffff600400-ffffffffff6007ff 0 [kernel].vsyscall_1 in kallsyms as [kernel].6 ffffffffff600800-ffffffffffffffff 0 [kernel].vsyscall_2 in kallsyms as [kernel].8 Maps only in kallsyms: ffffffffff600130-ffffffffff6003ff 0 [kernel].4 ---- end ---- vmlinux symtab matches kallsyms: Ok [acme@doppio linux-2.6-tip]$ In the above case we only know the name of the non contiguous kernel ranges in the address space when reading the symbol information from the ELF symtab in vmlinux. The /proc/kallsyms file lack this, we only notice they are separate because there are modules after the kernel and after that more kernel functions, so we need to have a module rbtree backed by the module .ko path to get symtabs in the vmlinux case. The tool uses it to match by address to emit appropriate warning, but don't considers this fatal. The .init.text and .exit.text ines, of course, aren't in kallsyms, so I left these cases just as extra info in verbose mode. The end of the sections also aren't in kallsyms, so we the symbols layer does another pass and sets the end addresses as the next map start minus one, which sometimes pads, causing harmless mismatches. But at least the symbols match, tested it by copying /proc/kallsyms to /tmp/kallsyms and doing changes to see if they were detected. This first test also should serve as a first stab at documenting the symbol library by providing a self contained example that exercises it together with comments about what is being done. More tests to check if actions done on a monitored app, like doing mmaps, etc, makes the kernel generate the expected events should be added next.

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. Build-ids are just the first user of perf-inject - potentially anything that needs userspace processing to augment the trace stream with additional information could make use of this facility.

perf tools: Reorganize the Makefile feature tests 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.

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: Reorganize the Makefile feature tests 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.

Also adds the Perl implementation of the generate_script() trace_scripting_op, which creates a ready-to-run perf trace Perl script based on existing trace data. Scripts generated by this implementation print out all the fields for each event mentioned in perf.data (and will detect and generate the proper scripting code for 'flag' and 'symbolic' fields), and will additionally generate handlers for the special 'trace_unhandled', 'trace_begin' and 'trace_end' handlers.

perf trace: Add Perl scripting support Implement trace_scripting_ops to make Perl a supported perf trace scripting language. Additionally adds code that allows Perl trace scripts to access the 'flag' and 'symbolic' (__print_flags(), __print_symbolic()) field information parsed from the trace format files. Also adds the Perl implementation of the generate_script() trace_scripting_op, which creates a ready-to-run perf trace Perl script based on existing trace data. Scripts generated by this implementation print out all the fields for each event mentioned in perf.data (and will detect and generate the proper scripting code for 'flag' and 'symbolic' fields), and will additionally generate handlers for the special 'trace_unhandled', 'trace_begin' and 'trace_end' handlers. Script authors can simply remove the printing code to implement their own custom event handling.

perf tools: Reorganize the Makefile feature tests 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.

perf tools: Reorganize the Makefile feature tests 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.

perf: Add the timechart tool timechart is a tool to visualize what is going on in the system. The user makes a trace of what is going on with > perf record --timechart /usr/bin/some_command and then can turn the output of this into an svg file > perf timechart which then can be viewed with any SVG view; inkscape works well enough for me. The idea behind timechart is to create a "infinitely zoomable" picture; something that has high level information on a 1:1 zoom level, but which exposes more details every time you zoom into a specific area.

perf trace: Add Perl scripting support Implement trace_scripting_ops to make Perl a supported perf trace scripting language. Additionally adds code that allows Perl trace scripts to access the 'flag' and 'symbolic' (__print_flags(), __print_symbolic()) field information parsed from the trace format files. Also adds the Perl implementation of the generate_script() trace_scripting_op, which creates a ready-to-run perf trace Perl script based on existing trace data. Scripts generated by this implementation print out all the fields for each event mentioned in perf.data (and will detect and generate the proper scripting code for 'flag' and 'symbolic' fields), and will additionally generate handlers for the special 'trace_unhandled', 'trace_begin' and 'trace_end' handlers. Script authors can simply remove the printing code to implement their own custom event handling.

To give scripts access to the other fields and/or any other data or metadata in the main perf executable that might be useful, a way to access the C data in perf from Perl is needed; this patch uses the Perl XS facility to do it for the common_xxx event fields not passed to handler functions. Context.pm exports three functions to Perl scripts that access fields for the current event by calling back into perf: common_pc(), common_flags() and common_lock_depth(). Support for common_flags() field values was added to Core.pm and a script used to sanity check these and other basic scripting features, check-perf-trace.pl, was also added.

perf_counter tools: Generate per command manpages (and pdf/html, etc.) Import Git's nice .txt => {man/html/pdf} generation machinery. Fix various errors in the Documentation/perf*.txt description as well. Also fix a bug in builtin-help: we'd map 'perf help top' to 'perftop' if only the 'perf' binary is in the default PATH - confusing the manpage logic. I dont fully understand why Git did it this way - but i suppose it's a migration artifact from their migration from standalone git-xyz commands to 'git xyz' commands. The perf tools were always using the modern form so it's not an issue there.

perf_counter tools: Generate per command manpages (and pdf/html, etc.) Import Git's nice .txt => {man/html/pdf} generation machinery. Fix various errors in the Documentation/perf*.txt description as well. Also fix a bug in builtin-help: we'd map 'perf help top' to 'perftop' if only the 'perf' binary is in the default PATH - confusing the manpage logic. I dont fully understand why Git did it this way - but i suppose it's a migration artifact from their migration from standalone git-xyz commands to 'git xyz' commands. The perf tools were always using the modern form so it's not an issue there.

perf trace: Add interface to access perf data from Perl handlers The Perl scripting support for perf trace allows most of a trace event's data to be accessed directly as handler arguments, but not all of it e.g. the less common fields aren't passed in. To give scripts access to the other fields and/or any other data or metadata in the main perf executable that might be useful, a way to access the C data in perf from Perl is needed; this patch uses the Perl XS facility to do it for the common_xxx event fields not passed to handler functions. Context.pm exports three functions to Perl scripts that access fields for the current event by calling back into perf: common_pc(), common_flags() and common_lock_depth(). Support for common_flags() field values was added to Core.pm and a script used to sanity check these and other basic scripting features, check-perf-trace.pl, was also added.
