STRUCT SND_SOC_ACPI_CODECS(9)

💅 struct snd_soc_acpi_codecs(9)

okay so you're in the Kernel API Manual, section 9, and the star of the show is struct snd_soc_acpi_codecs 🎀

---

✨ NAME ✨

struct snd_soc_acpi_codecs — bestie, this is the struct that holds the secondary codec info, y'know, the extras that aren't the one you already matched 🫶. That data gets handed off to the quirk function so it can match up against the devices that ACPI actually detected. it's giving "supporting cast, but make it essential" 👑

---

🌸 SYNOPSIS 🌸

struct snd_soc_acpi_codecs {
    int num_codecs;
    u8 codecs[SND_SOC_ACPI_MAX_CODECS][ACPI_ID_LEN];
 };

look at her. so compact. so iconic. literally the whole vibe in two fields 💜

🦋 Members 🦋

• num_codecs — the number of secondary codecs chillin' in this platform. like, how many plus-ones are we bringing 🔥
• codecs — this is the one holding the codec IDs, no cap. it's a 2D array: SND_SOC_ACPI_MAX_CODECS rows of ACPI_ID_LEN — so it's a whole lil roster of IDs, and every single one is exactly ACPI_ID_LEN wide 💅

ngl bestie, if you're matching ACPI-detected devices against secondary codecs, this struct is your main character. go off 👑
