printk: Rename resume_console to console_resume_all

2025-03-11T10:51:27+00:00

The function resume_console has a misleading name, since it resumes all consoles, so rename it accordingly.

pm-graph: Make git ignore sleepgraph.py artifacts

2024-09-04T12:32:09+00:00

By default, sleepgraph.py creates suspend-{date}-{time} directories to store artifacts, or suspend-{date}-{time}-xN if the --multi option is used. Ignore those directories by adding a .gitignore file.

PM: tools: sleepgraph: Recognize "CPU killed" messages

2023-03-27T17:24:08+00:00

On the arm64 platform with PSCI, the core log of CPU offline is as follows: [ 100.431501] CPU1: shutdown [ 100.454820] psci: CPU1 killed (polled 20 ms) [ 100.459266] CPU2: shutdown [ 100.482575] psci: CPU2 killed (polled 20 ms) [ 100.486057] CPU3: shutdown [ 100.513974] psci: CPU3 killed (polled 28 ms) [ 100.518068] CPU4: shutdown [ 100.541481] psci: CPU4 killed (polled 24 ms) Prevent sleepgraph from mistakenly treating the "CPU up" message as part of the suspend flow (because it should be regarded as part of the resume flow) by making it recognize the "CPU* killed" messages above.

pm-graph: Update to v5.11

2023-03-27T17:19:14+00:00

install_latest_from_github.sh: - Added a new script which allows users to install the latest pm-graph from the upstream github repo. This is useful if the kernel source version has issues that have already been fixed in github. sleepgraph.py: - Updated all the dmesg suspend/resume PM print formats to be able to process recent timelines using dmesg only. - Added ethtool output to the log for the system's ethernet device id the ethtool exists. This helps in debugging network issues. - Made the tool more robustly handle events where mangled dmesg or ftrace outputs do not include all the requisite data. The tool fails gracefully instead of creating a garbled timeline. Signed-off-by: Todd Brandt [ rjw: Changelog edits ] Signed-off-by: Rafael J. Wysocki
