Pekka Enberg 981c125269 perf symbols: Check '/tmp/perf-' symbol file ownership
The external symbol files are generated by JIT compilers, for example, but we
need to make sure they're ours before injecting them to 'perf report'.

Jiri Olsa 4c09bafae3 perf sched: Do not delete session object prematurely
The session object is released prematurely when processing events for
latency command. The session's thread objects are used within the
output_lat_thread function.

Runnning following commands:

 # perf sched record
 # perf sched latency

the latter displays incorrect data and might cause access violation.

Jiri Olsa 9941c96ad8 perf tools: Add support to install perf python extension
Adding install-python_ext target to install python extension related
files.  Installation directory is governed by python distutils package
and follows the DESTDIR variable settings.

Also moving python extension build output into '$(O)python_ext_build'
directory and making it configurable via PYTHON_EXTBUILD variable.

Keeping the '$(O)python/perf.so' file, so it could be used for testing
as of until now.

Jonathan Nieder aba8d05607 perf tools: do not look at ./config for configuration
In addition to /etc/perfconfig and $HOME/.perfconfig, perf looks for
configuration in the file ./config, imitating git which looks at
$GIT_DIR/config.  If ./config is not a perf configuration file, it
fails, or worse, treats it as a configuration file and changes behavior
in some unexpected way.

"config" is not an unusual name for a file to be lying around and perf
does not have a private directory dedicated for its own use, so let's
just stop looking for configuration in the cwd.  Callers needing
context-sensitive configuration can use the PERF_CONFIG environment
variable.

So that we get a proper warning in the TUI in cases like:

 $ perf report --stdio -g fractal,0.5,caller --sort pid
 Selected -g but no callchain data. Did you call 'perf record' without -g?
 $

The --stdio case is ok because it uses fprintf, ui__warning is needed to
figure out if --stdio or --tui is being used.

Thomas Renninger 029e9f7366 cpupower: Do detect IDA (opportunistic processor performance) via cpuid
IA32-Intel Devel guide Volume 3A - 14.3.2.1
-------------------------------------------
...
Opportunistic processor performance operation can be disabled by setting bit 38 of
IA32_MISC_ENABLES. This mechanism is intended for BIOS only. If
IA32_MISC_ENABLES[38] is set, CPUID.06H:EAX[1] will return 0.

Better detect things via cpuid, this cleans up the code a bit
and the MSR parts were not working correctly anyway.

Whether the HW really enters these boost modes can be verified via

Dominik Brodowski 7fe2f6399a cpupowerutils - cpufrequtils extended with quite some features
CPU power consumption vs performance tuning is no longer
limited to CPU frequency switching anymore: deep sleep states,
traditional dynamic frequency scaling and hidden turbo/boost
frequencies are tied close together and depend on each other.
The first two exist on different architectures like PPC, Itanium and
ARM, the latter (so far) only on X86. On X86 the APU (CPU+GPU) will
only run most efficiently if CPU and GPU has proper power management
in place.

Users and Developers want to have *one* tool to get an overview what
their system supports and to monitor and debug CPU power management
in detail. The tool should compile and work on as many architectures
as possible.

Once this tool stabilizes a bit, it is intended to replace the
Intel-specific tools in tools/power/x86

Jiri Olsa 13b62567e9 perf tools: Add automated tests for events parsing
Adding builtin test for parse_events function, which is
responsible for parsing/processing "-e" option for
stat/top/record commands.

This new test will run within the builtin test command suite
(perf test).

One or several tests were added for each type of event.
More tests could be added easily if needed.

Jiri Olsa f120f9d51b perf tools: De-opt the parse_events function
Moving out the option parameter from parse_events function,
and adding new parse_events_option function instead.

The option parameter is used only to carry "struct perf_evlist"
pointer for chaining new events. Putting it away, enable us
to call parse_events from other places without using the
option parameter.

David Ahern eda3913bb7 perf tools: Fix endian conversion reading event attr from file header
The perf_event_attr struct has two __u32's at the top and
they need to be swapped individually.

With this change I was able to analyze a perf.data collected in a
32-bit PPC VM on an x86 system. I tested both 32-bit and 64-bit
binaries for the Intel analysis side; both read the PPC perf.data
file correctly.

-v2:
 - changed the existing perf_event__attr_swap() to swap only elements
   of perf_event_attr and exported it for use in swapping the
   attributes in the file header
 - updated swap_ops used for processing events

Jiri Olsa 0111919da2 perf tools: Add missing 'node' alias to the hw_cache[] array
Add "node" as a simple alias for NODE cache events.

The addition of NODE cache events broke the parse_alias
function, so any mismatched event caused the segfault, like:

  # ./perf stat -e krava ls

The hw_cache/hw_cache_op/hw_cache_result arrays needs to follow
PERF_COUNT_HW_CACHE_*MAX enums. Adding those MAXs to be size
of those arrays, so possible ommision in future wil not lead to
segfault.

Adding read/write/prefetch as allowed operations for node cache
event.

Steven Rostedt 250bae8be0 ktest: Fix bug when ADD_CONFIG is set but MIN_CONFIG is not
The MIN_CONFIG is a single config that is considered to have all the
configs that are required to boot the box.

ADD_CONFIG is a list of configs that we add that may contain configs
known to be broken (set off) or just configs that we want every box to
have and this can include shared configs.

If a config has no MIN_CONFIG defined, but has multiple files defined
for the ADD_CONFIG, the test will die, because the MIN_CONFIG will
default to ADD_CONFIG. The problem is the code to open MIN_CONFIG
expects a string of one file, not multiple, and the open will fail.

Since the real minconfig that is used is a concatination of MIN_CONFIG
and ADD_CONFIG files, we change the code to open that instead of
whatever MIN_CONFIG defaults to.

Steven Rostedt 43d1b6518e ktest: Keep fonud configs separate from default configs
The IGNORE_CONFIG file holds the configs that we don't want to change
(with their proper settings). But on start up, the make noconfig is
executed, and the configs that are on are also put into the ignore
config category. But these are configs that were forced on by the
kconfig scripts and not something that we found must be enabled to boot
our machine. By keeping the configs that are forced on by default,
separate from the configs we found that are required to boot the box, we
can get a much more interesting IGNORE_CONFIG. In fact, the
IGNORE_CONFIG can usually end up being the must have configs to boot,
and only have 6 or 7 configs set.

Steven Rostedt 35ce5952e6 ktest: Add prompt to use OUTPUT_MIN_CONFIG
If the defined OUTPUT_MIN_CONFIG in the make_min_config test exists,
then give a prompt to ask the user if they want to use that config
instead, as it is very often the case, especially when the test has been
interrupted. The OUTPUT_MIN_CONFIG is usually the config that one wants
to use to continue the test where they left off.

But if START_MIN_CONFIG is defined (thus the MIN_CONFIG is not the
default), then do not prompt, as it will be annoying if the user has
this as one of many tests, and the test pauses waiting for input, while
the user is sleeping.

Steven Rostedt b9066f6c0e ktest: Use Kconfig dependencies to shorten time to make min_config
To save time, the test does not just grab any option and test
it. The Kconfig files are examined to determine the dependencies
of the configs. If a config is chosen that depends on another
config, that config will be checked first. By checking the
parents first, we can eliminate whole groups of configs that
may have been enabled.

For example, if a USB device config is chosen and depends on
CONFIG_USB, the CONFIG_USB will be tested before the device.
If CONFIG_USB is found not to be needed, it, as well as all
configs that depend on it, will be disabled and removed from
the current min_config.

Note, the code from streamline_config (make localmodconfig)
was copied and used to find the dependencies in the Kconfig file.

Steven Rostedt 4c4ab1204f ktest: Add test type make_min_config
After doing a make localyesconfig, your kernel configuration may
not be the most useful minimum configuration. Having a true minimum
config that you can use against other configs is very useful if
someone else has a config that breaks on your code. By only forcing
those configurations that are truly required to boot your machine
will give you less of a chance that one of your set configurations
will make the bug go away. This will give you a better chance to
be able to reproduce the reported bug matching the broken config.

Note, this does take some time, and may require you to run the
test over night, or perhaps over the weekend. But it also allows
you to interrupt it, and gives you the current minimum config
that was found till that time.

Note, this test automatically assumes a BUILD_TYPE of oldconfig
and its test type acts like boot.

TODO: add a test version that makes the config do more than just
      boot, like having network access.
