# 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
