# CallGraph function skip list

#

# This file contains a list of functions which are

# meant to be skipped in the callgraph trace. It reduces

# the callgraph html file size by treating these functions

# as leaves with no child calls. It can be editted by

# adding or removing function symbol names.

#

# The sleepgraph tool automatically pulls this file in when

# it is found in the config folder. It can be ignored if

# the tool is called with "-cgskip off".

[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]

#
