2010-11-10perf, ui: Eliminate stack-smashing protection compiler complaintCyrill Gorcunov
The gcc complains about small auto-var strings being allocated from stack space. Make them const to avoid this: | CC util/ui/util.o | cc1: warnings being treated as errors | util/ui/util.c: In function ‘ui__dialog_yesno’: | util/ui/util.c:108: error: not protecting function: no buffer at least 8 bytes long | make: *** [util/ui/util.o] Error 1 The real bug is in the newtWinChoice() ABI - but that's an externality we cannot fix here, so we use this workaround.

2010-10-21perf probe: Add basic module supportMasami Hiramatsu
Add basic module probe support on perf probe. This introduces "--module <MODNAME>" option to perf probe for putting probes and showing lines and variables in the given module. Currently, this supports only probing on running modules. Supporting off-line module probing is the next step. e.g.) [show lines] # ./perf probe --module drm -L drm_vblank_info <drm_vblank_info:0> 0 int drm_vblank_info(struct seq_file *m, void *data) 1 { struct drm_info_node *node = (struct drm_info_node *) m->private 3 struct drm_device *dev = node->minor->dev; ... [show vars] # ./perf probe --module drm -V drm_vblank_info:3 Available variables at drm_vblank_info:3 @<drm_vblank_info+20> (unknown_type) data struct drm_info_node* node struct seq_file* m [put a probe] # ./perf probe --module drm drm_vblank_info:3 node m Add new event: probe:drm_vblank_info (on drm_vblank_info:3 with node m) You can now use it on all perf tools, such as: perf record -e probe:drm_vblank_info -aR sleep 1 [list probes] # ./perf probe -l probe:drm_vblank_info (on drm_vblank_info:3@drivers/gpu/drm/drm_info.c with ...

2010-10-04perf trace scripting: Fix extern struct definitionsStephane Eranian
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.

2010-08-27perf: Initialize callchains roots's childen hitsFrederic Weisbecker
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.

When looking at a callchains enabled perf data file one can find it tiresome to start with all callchains collapsed and then to have to go one by one expanding them. So associate 'E' with "Expand all callchains" and 'C' with "Collapse all callchains". This way now one can have the top level view and then switch to/from having all callchains expanded.

2010-08-22perf: Support for callchains mergeFrederic Weisbecker
If we sort the histograms by comm, which is the default, we need to merge some of them, typically different thread histograms of a same process, or just same comm. But during this merge, we forgot to merge callchains. So imagine we have three threads (tids: 1000, 1001, 1002) that belong to comm "foo". tid 1000 got 100 events tid 1001 got 10 events tid 1002 got 3 events Once we merge these histograms to get a per comm result, we'll finally get: "foo" got 113 events The problem is if we merge 1000 and 1001 histograms into 1002, then the end merge result, wrt callchains, will be only callchains that belong to 1002. This is because we haven't handled callchains in the merge. Only those from one of the threads inside a common comm survive. It means during this merge, we can lose a lot of callchains. Fix this by implementing callchains merge and apply it on histograms that collapse.

Right now it will just sort and position at the hottest line, i.e. the one where more samples were taken. It will be at the center of the screen and later TAB/shift-TAB will cycle thru the hottest lines.

2010-08-10perf symbols: Ignore mapping symbols on ARMDave Martin
ARM ELF files use symbols with special names $a, $t, $d to identify regions of ARM code, Thumb code and data within code sections. 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.
