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 ...
