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 <luca.ceresoli@bootlin.com> Reviewed-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Link: https://lore.kernel.org/r/20240416-vizdapm-ng-v1-3-5d33c0b57bc5@bootlin.com Signed-off-by: Mark Brown <broonie@kernel.org> |
