# CONFIG_HIST_TRIGGERS_DEBUG: # # Add "hist_debug" file for each event, which when read will # dump out a bunch of internal details about the hist triggers # defined on that event. # # The hist_debug file serves a couple of purposes: # # - Helps developers verify that nothing is broken. # # - Provides educational information to support the details # of the hist trigger internals as described by # Documentation/trace/histogram-design.rst. # # The hist_debug output only covers the data structures # related to the histogram definitions themselves and doesn't # display the internals of map buckets or variable values of # running histograms. # # If unsure, say N. # # Symbol: HIST_TRIGGERS_DEBUG [=n] # Type : bool # Defined at kernel/trace/Kconfig:850 # Prompt: Hist trigger debug support # Depends on: TRACING_SUPPORT [=y] && FTRACE [=y] && HIST_TRIGGERS [=y] # Location: # -> Kernel hacking # -> Tracers (FTRACE [=y]) # # # # CONFIG_HIST_TRIGGERS_DEBUG is not set
