sst_fill_module_list(9)

💖 sst_fill_module_list(9) 💖

okay bestie, we're in the Kernel API Manual today and this one is a lil C function that literally just introduces people to each other — it's giving matchmaker energy, no cap 🫶

---

✨ NAME ✨

sst_fill_module_list — populate the list of modules/gains for a pipe

like it literally fills in the list of modules and gains for a pipe, that's the whole job, periodt 💅

---

🦋 SYNOPSIS 🦋

int sst_fill_module_list (struct snd_kcontrol *kctl , struct
       snd_soc_dapm_widget *w , int type );

---

🎀 ARGUMENTS 🎀

• kctl — kcontrol pointer 🎛️ (yes it's a pointer, yes it's a struct snd_kcontrol *)
• w — dapm widget 🌸
• type — widget type 🏷️

---

💜 DESCRIPTION 💜

So here's the tea, bestie: this function fills the widget pointer in the kcontrol private data, and also fills the kcontrol pointer in the widget private data. Mutual. Two-way. Iconic. 💞

The widget pointer is used to send the algo/gain in the .put handler if the widget is powerd on. 🔥

The kcontrol pointer is used to send the algo/gain in the widget power ON/OFF event handler. And here's the important bit: each widget (pipe) has multiple algos stored in the algo_list. 👑

ngl this is the kind of function that's small but the whole pipe situation lowkey falls apart without it 🙈
