Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

#
# 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)
verbose: false

# Suspend Mode
# e.g. standby, mem, freeze, disk (default: mem)
mode: mem

# 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)
addlogs: false

# Display function calls
# graph source functions in the timeline (default: false)
dev: true

# Callgraph
# gather detailed ftrace callgraph data on all timeline events (default: false)
callgraph: false

# Back to Back Suspend/Resume
# Run two suspend/resumes back to back (default: false)
x2: false

# Back to Back Suspend Delay
# Time delay between the two test runs in ms (default: 0 ms)
x2delay: 0

# Minimum Device Length
# graph only devices longer than min in the timeline (default: 0.001 ms)
mindev: 1

# 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
override-timeline-functions: true

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

Annotation

• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: atlas-only.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
