snd_soc_new_ac97_component(9)

💅 snd_soc_new_ac97_component 💅

okay so real talk, this is a page straight out of the Kernel API Manual — literally the snd_soc_new_ac97_component(9) entry, and we're gonna get you through it bestie, no cap.

---

✨ NAME ✨

snd_soc_new_ac97_component — initailise AC97 device 🎀 (yes that's how it's spelled in the header, we don't gatekeep typos here, it means "initialise")

---

🦋 SYNOPSIS 🦋

struct snd_ac97 * snd_soc_new_ac97_component (struct snd_soc_component
*component , unsigned int id , unsigned int id_mask );

like, that's the whole signature, she's a little long but she eats 💅

---

🌸 ARGUMENTS 🌸

• component — the audio component, bestie. that's your main character right there 👑
• id — the expected device ID. the one you're manifesting ✨
• id_mask — mask that gets applied to the device ID before it's compared with id. it's giving "vibe check but with bitwise math" 🧚

---

💖 DESCRIPTION 💖

So this function initialises AC97 component resources — but literally only for use by ad-hoc devices. that's the whole scope, no cap. 🙈

Now here's the important bit (lowkey the tea ☕): if id is not 0, this function will reset the device first, then read the ID from the device and check whether it matches the expected ID. if it doesn't match? an error gets returned and the device will not be registered. periodt. 💀

---

🔥 RETURN 🔥

An ERR_PTR on failure 😭 — or a valid snd_ac97 struct on success 🎉🫶
