2024-08-23ASoC: dapm-graph: show path name for non-static routesLuca Ceresoli1-2/+8
Many routes are just static, not modifiable at runtime. Show the route name for all the other routes as an edge label in the generated graph. Signed-off-by: Luca Ceresoli <[email protected]> Link: https://patch.msgid.link/[email protected] Signed-off-by: Mark Brown <[email protected]>
2024-08-23ASoC: dapm-graph: visualize component On/Off bias levelLuca Ceresoli1-3/+18
Read the bias_level debugfs files (ignored so far) and visualize the On/Off state of each component using different graphic attributes in the generated graph.

2024-08-23ASoC: dapm-graph: remove the "ROOT" clusterLuca Ceresoli1-8/+13
Widgets not belonging to any component are currently represented inside a cluster labeled "ROOT". This is not a correct representation of the actual structure, as these widgets are not necessarily related to each other as the ones inside actual components are. Improve the graphical representation by not adding a cluster around these widgets. Now a dot cluster represents a card component faithfully. This will be particularly important with the upcoming improvements which will visualize the component bias_level.

2024-04-21ASoC: dapm-graph: new tool to visualize DAPM stateLuca Ceresoli1-0/+303
Add a tool to generate a picture of the current DAPM state for a sound card. dapm-graph is inspired by vizdapm which used to be published on a Wolfson Micro git repository now disappeared, and has a few forks around: https://github.com/mihais/asoc-tools https://github.com/alexandrebelloni/asoc-tools dapm-graph is a full reimplementation with several improvements while still being a self-contained shell script: Improvements to rendered output: - shows the entire card, not one component hierarchy only - each component is rendered in a separate box - shows widget on/off status based on widget information alone (the original vizdapm propagates the "on" green colour to the first input widget) - use bold line and gray background and not only green/red line to show on/off status (for the color blind) Improvements for embedded system developers: - remote mode: get state of remote device (possibly with minimal rootfs) via SSH, but parsing locally for faster operation - compatible with BusyBox shell, not only bash Usability improvements: - flexible command line (uses getopts for parsing) - detailed help text - flag to enable detailed debug logging - graphviz output format detected from file extension, not hard coded - a self-contained shell script Usage is designed to be simple: dapm-grpah -c CARD - get state from debugfs for CARD dapm-grpah -c CARD -r REMOTE_TARGET - same, but remotely via SSH dapm-grpah -d STATE_DIR - from a local copy of the debugfs tree for a card Signed-off-by: Luca Ceresoli <[email protected]> Reviewed-by: Alexandre Belloni <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Mark Brown <[email protected]>
