#
# This is the configuration file for sleepgraph. It contains
# all the tool arguments so that they don't have to be given on the
# command line. It also includes advanced settings for functions
# and kprobes. It is run like this
#
#    sudo ./sleepgraph.py -config thisfile.txt
#

[Settings]

# Verbosity
# print verbose messages (default: false)

# Automatic Wakeup
# Use rtcwake to autoresume after X seconds, or off to disable (default: 15)
rtcwake: 15

# Add Logs
# add the dmesg and ftrace log to the html output (default: false)

# Minimum Device Length
# graph only devices longer than min in the timeline (default: 0.001 ms)

# Minimum Callgraph Length
# provide callgraph data for blocks longer than min (default: 0.001 ms)
mincg: 1

# Suspend/Resume Gap
# insert a small visible gap between suspend and resume on the timeline (default: false)
srgap: false

# Output Directory Format
# output folder for html, ftrace, and dmesg. Use {date} and {time} for current values
output-dir: suspend-{hostname}-{date}-{time}-custom

# Override default timeline entries
# Do not use the internal default functions for timeline entries (default: false)
# Set this to true if you intend to only use the ones defined in this config

[timeline_functions_x86_64]
#
# Function calls to display in the timeline alongside device callbacks.
# The tool has an internal set of these functions which should cover the
# whole of kernel execution, but you can append or override here.
#
# This is a list of kprobes which use both symbol data and function arg data.
# The function calls are displayed on the timeline alongside the device blocks.
# The args are pulled directly from the stack using this architecture's registers
# and stack formatting. Three pieces of info are required. The function name,
# a format string, and an argument list
#
# Entry format:
#
#   function: format{fn_arg1}_{fn_arg2} fn_arg1 fn_arg2 ... [color=purple]
#
# Required Arguments:
#
#   function: The symbol name for the function you want probed, this is the
#             minimum required for an entry, it will show up as the function
#             name with no arguments.
#
#       example: _cpu_up:
#
# Optional Arguments:
#
#   format: The format to display the data on the timeline in. Use braces to
#           enclose the arg names.
#
#       example: CPU_ON[{cpu}]
#
#   color: The color of the entry block in the timeline. The default color is
#          transparent, so the entry shares the phase color. The color is an
#          html color string, either a word, or an RGB.
#
#       example: [color=#CC00CC]
#
#   arglist: A list of arguments from registers/stack addresses. See URL:
#            https://www.kernel.org/doc/Documentation/trace/kprobetrace.txt
#
#       example: cpu=%di:s32
#
# Example: Display cpu resume in the timeline
#
#       _cpu_up: CPU_ON[{cpu}] cpu=%di:s32 [color=orange]
#
_cpu_down: CPU_OFF[{cpu}] cpu=%di:s32
_cpu_up: CPU_ON[{cpu}] cpu=%di:s32

# Dev mode function calls to display inside timeline entries

#
#       example: ata{port}_port_reset
#
#   color: The color of the entry block in the timeline. The default color is
