2011-08-08perf tools: Add support to install perf python extensionJiri Olsa2-7/+33
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.

2011-08-08perf tools: do not look at ./config for configurationJonathan Nieder1-7/+0
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.

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.

2011-07-29cpupowerutils - cpufrequtils extended with quite some featuresDominik Brodowski72-0/+14417
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 Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

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 Signed-off-by: David Ahern <dsahern@gmail.com> Acked-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: acme@ghostprotocols.net Cc: peterz@infradead.org Cc: paulus@samba.org Cc: <stable@kernel.org> Link: http://lkml.kernel.org/r/1310754849-12474-1-git-send-email-dsahern@gmail.com Signed-off-by: Ingo Molnar <mingo@elte.hu>
2011-07-21perf tools: Add missing 'node' alias to the hw_cache[] arrayJiri Olsa1-5/+8
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.

2011-07-15ktest: Fix bug when ADD_CONFIG is set but MIN_CONFIG is notSteven Rostedt1-12/+7
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.

2011-07-15ktest: Keep fonud configs separate from default configsSteven Rostedt1-4/+8
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. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-07-15ktest: Add prompt to use OUTPUT_MIN_CONFIGSteven Rostedt2-14/+59
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.

2011-07-15ktest: Use Kconfig dependencies to shorten time to make min_configSteven Rostedt2-22/+273
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. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2011-07-15ktest: Add test type make_min_configSteven Rostedt2-4/+301
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.
