We want to perform remote audio auto test, need the audio jack to change from plugout to plugin or vice versa by software ways.
Here the design is creating a sound-core root folder in the debugfs dir, and each sound card will create a folder cardN under sound-core, then the sound jack will create folders by jack_ctrl->ctrl->id.name, and will create 2 file nodes jackin_inject and sw_inject_enable in the folder, this is the layout of folder on a machine with 2 sound cards: $tree $debugfs_mount_dir/sound-core sound-core/ ├── card0 │ ├── HDMI!DP,pcm=10 Jack │ │ ├── jackin_inject │ │ └── sw_inject_enable
- sound_core_debugfs_root = debugfs_create_dir("sound-core", NULL);
I would just use "sound" directory name here. Why "core" suffix?
OK, will change it to sound.
thx.
