* perf trace scripting: Fix extern struct definitionsStephane Eranian2010-10-04
| | | | | | | | | | | | | | | | | | | | | | | Both python_scripting_ops and perl_scripting_ops have two global definitions. One in trace-event-scripting.c and one in their respective scripting-engine modules. The issue is that depending on the linker order one definition or the other is chosen. One is uninitialized (bss), while the other is initialized. If the uninitialized version is chosen, then perf does not function properly. This patch fixes this by adding the extern prefix to the definitions in trace-event-scripting.c. Cc: David S.

* perf: Initialize callchains roots's childen hitsFrederic Weisbecker2010-08-26
| | | | | | | | | | | | | | | | | | | | | | | | Each histogram entry has a callchain root that stores the callchain samples. However we forgot to initialize the tracking of children hits of these roots, which then got random values on their creation. The root children hits is multiplied by the minimum percentage of hits provided by the user, and the result becomes the minimum hits expected from children branches. If the random value due to the uninitialization is big enough, then this minimum number of hits can be huge and eventually filter every children branches. The end result was invisible callchains. All we need to fix this is to initialize the children hits of the root.

* perf tools: Fix build error on read only source.Kusanagi Kouichi2010-08-18
| | | | | | | | | | | | | | | | | | | 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 annotate tui: Fix exit and RIGHT keys handlingArnaldo Carvalho de Melo2010-08-16
| | | | | | | | | | | | | | | | | As part of ongoing effort to reduce the coupling with libnewt, browsers are being changed to return the exit key. The annotate browser is not returning it as expected by builtin-annotate when annotating multiple symbols (when 'perf annotate' is called without specifying a symbol name). Fix it by returning the exit key and also adding the RIGHT key as a exit key so that going to the next symbol in the TUI can work again.

This will support power frequency tracing by all cpufreq drivers trace_power_frequency did not trace frequency changes correctly when the userspace governor was used or when CPU cores' frequency depend on each other. -> Moving this into the CPUFREQ_POSTCHANGE notifier and pass the cpu which gets switched automatically fixes this.

It will be at the center of the screen and later TAB/shift-TAB will cycle thru the hottest lines.

This can cause confusing output from the perf tools, especially for partially stripped binaries, or binaries containing user-added zero-sized symbols (which may occur in hand-written assembler which hasn't been fully annotated with .size directives). This patch filters out these symbols at load time.
