Wrapping the kernel headers is dangerous when it comes to arch headers. Once we wrap asm/types.h, it will also replace the glibc asm/types.h, not only the kernel one. This results in build errors on some machines. Drop this wrapper and do its work from linux/types.h wrapper, also the glibc asm/types.h can already handle most of the type definition it was doing (typedef __u64, __u32, etc...). Todo: Check the others asm/*.h wrappers to prevent from other conflicts. Reported-by:

When using gdb to debug perf, it is practically impossible to use when perf is compiled with -O6. For developers, this patch adds the DEBUG feature to the make command line so that a developer can easily remove the optimization flag. LKML-Reference: <1255590330.8392.446.camel@twins> Signed-off-by:

Randy Dunlap reported that 'make NO_64BIT=1' fails to build a pure 32-b it binary on 64-bit/64-bit x86 systems. The reason is that we dont pass in the -m32 and GCC defaults to -m64. So pass it in - and also extend the warning message about libelf dependencies - glibc-dev[el] is needed as well beyond the libelf library. Reported-by:

Representing modules as struct map entries, backed by a DSO, etc, using /proc/modules to find where the module is loaded. DSOs now can have a short and long name, so that in verbose mode we can show exactly which .ko or vmlinux image was used. As kernel modules now are a DSO separate from the kernel, we can ask for just the hits for a particular set of kernel modules, just like we can do with shared libraries: [root@doppio linux-2.6-tip]# perf report -n --vmlinux /home/acme/git/build/tip-recvmmsg/vmlinux --modules --dsos \[drm\] | head -15 84.58% 13266 Xorg [k] drm_clflush_pages 4.02% 630 Xorg [k] trace_kmalloc.clone.0 3.95% 619 Xorg [k] drm_ioctl 2.07% 324 Xorg [k] drm_addbufs 1.68% 263 Xorg [k] drm_gem_close_ioctl 0.77% 120 Xorg [k] drm_setmaster_ioctl 0.70% 110 Xorg [k] drm_lastclose 0.68% 106 Xorg [k] drm_open 0.54% 85 Xorg [k] drm_mm_search_free [root@doppio linux-2.6-tip]# Specifying --dsos /lib/modules/2.6.31-tip/kernel/drivers/gpu/drm/drm.ko would have the same effect. Allowing specifying just 'drm.ko' is left for another patch. Processing kallsyms so that per kernel module struct map are instantiated was also left for another patch. That will allow removing the module name from each of its symbols. struct symbol was reduced by removing the ->module backpointer and moving it (well now the map) to struct symbol_entry in perf top, that is its only user right now. The total linecount went down by ~500 lines. Signed-off-by:

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:

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.

This adds perf trace into the set of perf tools. It is written to fetch the tracepoint samples from perf events and display them, according to the events information given by the debugfs files through the util/trace* tools. It is a rough first shot and doesn't yet handle the cpu, timestamps fields and some other things. Example: perf record -f -e workqueue:workqueue_execution:record -F 1 -a perf trace kblockd/0-236 [000] 0.000000: workqueue_execution: thread=:236 func=cfq_kick_queue+0x0 kondemand/0-360 [000] 0.000000: workqueue_execution: thread=:360 func=do_dbs_timer+0x0 kondemand/0-360 [000] 0.000000: workqueue_execution: thread=:360 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 Todo: - A lot of things!

The soon coming perf trace needs to use printf with dynamically built formats. But we are using -Wformat=2 which is a shortcut for the following set: -Wformat -Wformat-security -Wformat-y2k -Wformat-nonliteral -Wformat-nonliteral warns when it can't check formats because they are not builtin constant strings, but we want to feature dynamic formats. What we want instead is Wformat=2 minus -Wformat-nonliteral, which is what this patch does. Signed-off-by:

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:

Improve and fix the handling of per-thread counter stats recorded via perf record -s. Previously we only displayed it in debug printouts (-D) and even that output was hard to disambiguate. I moved everything to utils/values.[ch] so that we may reuse it in perf stat. We get something like this now: # PID TID cache-misses cache-references 4658 4659 495581 3238779 4658 4662 498246 3236823 4658 4663 499531 3243162 Then it'll be easy to add --pretty=raw to display a single line per thread/event.

The copy we were using came from another copy I did for the dwarves (pahole) package, that came from the kernel years ago. The only function that is used by the perf tools and that isn't in the kernel is list_del_range, that I'm leaving in the perf tools only for now. Signed-off-by:

The tools/perf/util/rbtree.c copy already drifted by three csets: 4b324126 4c601178 16c047ad So remove the copy and use the lib/rbtree.c directly, sharing the source code while still generating a separate object file, since tools/perf uses a far more agressive -O6 switch. Signed-off-by:

Enable -Wextra. This found a few real bugs plus a number of signed/unsigned type mismatches/uncleanlinesses. It also required a few annotations All things considered it was still worth it so lets try with this enabled for now.

The zlib devel libraries may not be installed and since we aren't using zlib we may as well remove it. Signed-off-by:

We plan to display the callchains depending on some user-configurable parameters. To gather the callchains stats from the recorded stream in a fast way, this patch introduces an ad hoc radix tree adapted for callchains and also a rbtree to sort these callchains once we have gathered every events from the stream.
