d31babd7 - ASoC: dapm-graph: set fill colour of turned on nodes

Fri, 21 Feb 2025 20:39:32 +0000

ASoC: dapm-graph: set fill colour of turned on nodesSome tools like KGraphViewer interpret the "ON" nodes not having anexplicitly set fill colour as them being entirely black, which obscuresthe text on them and looks funny. In fact, I thought they were off forthe longest time. Comparing to the output of the `dot` tool, I assumethey are supposed to be white.Instead of speclawyering over who's in the wrong and must immediatelyatone for their wickedness at the altar of RFC2119, just be explicitabout it, set the fillcolor to white, and nobody gets confused.Signed-off-by: Nicolas Frattaroli Tested-by: Luca Ceresoli Reviewed-by: Luca Ceresoli Link: https://patch.msgid.link/20250221-dapm-graph-node-colour-v1-1-514ed0aa7069@collabora.comSigned-off-by: Mark Brown List of files: /linux-6.15/tools/sound/dapm-graph

a14b278a - ASoC: dapm-graph: show path name for non-static routes

Fri, 23 Aug 2024 07:46:01 +0000

ASoC: dapm-graph: show path name for non-static routesMany routes are just static, not modifiable at runtime. Show the route namefor all the other routes as an edge label in the generated graph.Signed-off-by: Luca Ceresoli Link: https://patch.msgid.link/20240823-dapm-graph-v1-3-989a47308c4c@bootlin.comSigned-off-by: Mark Brown List of files: /linux-6.15/tools/sound/dapm-graph

ASoC: dapm-graph: visualize component On/Off bias levelRead the bias_level debugfs files (ignored so far) and visualize the On/Offstate of each component using different graphic attributes in the generatedgraph.Signed-off-by: Luca Ceresoli Link: https://patch.msgid.link/20240823-dapm-graph-v1-2-989a47308c4c@bootlin.comSigned-off-by: Mark Brown List of files: /linux-6.15/tools/sound/dapm-graph

5a98c2e5 - ASoC: dapm-graph: remove the "ROOT" cluster

Fri, 23 Aug 2024 07:45:59 +0000

ASoC: dapm-graph: remove the "ROOT" clusterWidgets not belonging to any component are currently represented inside acluster labeled "ROOT". This is not a correct representation of the actualstructure, as these widgets are not necessarily related to each other asthe ones inside actual components are.Improve the graphical representation by not adding a cluster around thesewidgets. Now a dot cluster represents a card component faithfully. Thiswill be particularly important with the upcoming improvements which willvisualize the component bias_level.Signed-off-by: Luca Ceresoli Link: https://patch.msgid.link/20240823-dapm-graph-v1-1-989a47308c4c@bootlin.comSigned-off-by: Mark Brown List of files: /linux-6.15/tools/sound/dapm-graph

e7bb4389 - ASoC: dapm-graph: new tool to visualize DAPM state

Tue, 16 Apr 2024 06:00:26 +0000

ASoC: dapm-graph: new tool to visualize DAPM stateAdd a tool to generate a picture of the current DAPM state for a soundcard.dapm-graph is inspired by vizdapm which used to be published on a WolfsonMicro git repository now disappeared, and has a few forks around: https://github.com/mihais/asoc-tools https://github.com/alexandrebelloni/asoc-toolsdapm-graph is a full reimplementation with several improvements while stillbeing 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 bashUsability 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 scriptUsage 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 cardSigned-off-by: Luca Ceresoli Reviewed-by: Alexandre Belloni Link: https://lore.kernel.org/r/20240416-vizdapm-ng-v1-3-5d33c0b57bc5@bootlin.comSigned-off-by: Mark Brown List of files: /linux-6.15/tools/sound/dapm-graph
