sigmadsp_attach(9)

💖 sigmadsp_attach(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's a lil function from the kernel side of the sigmadsp world, and honestly? it's giving "small function, big responsibilities" energy. let's get into it 🫶

---

✨ NAME ✨

sigmadsp_attach — attach a sigmadsp instance to a ASoC component 🎀

---

🌸 SYNOPSIS 🌸

int sigmadsp_attach (struct sigmadsp *sigmadsp , struct
snd_soc_component *component );

---

🦋 ARGUMENTS 🦋

• sigmadsp — the sigmadsp instance you're attaching, bestie. the one being hooked up 💅
• component — the component you're attaching it to. the destination. the main character it's getting paired with ✨

---

💜 DESCRIPTION 💜

so like, typically you call this in the component's probe callback. that's the vibe — probe time, hookup time, no cap 🧚

⚠️ okay this is the important part, don't skip it ⚠️ note: once this function has been called, the firmware must not be released until after the ALSA snd_card that the component belongs to has been disconnected. and yes — even if sigmadsp_attach returns an error. 😭 like, an error return does not get you out of this. the firmware stays locked in until the card is disconnected. periodt. 🔥
