Re: [RFC][PATCH v3 1/4] alsa: jack: implement software jack injection via debugfs

Dne 28. 12. 20 v 9:00 Hui Wang napsal(a):

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?
