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.
No other scripts use `perfexec_instdir'.

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: 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: 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

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: 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: 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. )

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 tool: Add cgroup support
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

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 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: 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: 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 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

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: 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.
No other scripts use `perfexec_instdir'.

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.
No other scripts use `perfexec_instdir'.

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.
