STRUCT SND_SOC_ACPI_ADR_DEVICE(9)

💖 NAME 💖

struct snd_soc_acpi_adr_device — the descriptor bestie for a device that gets enumerated through _ADR, no cap ✨

So this is from the Kernel API Manual (yes, the kernel has lore too 🎀), and it's basically the little ID card a device carries around when it shows up via ACPI _ADR instead of the usual ways. Slay.

🌸 SYNOPSIS 🌸

struct snd_soc_acpi_adr_device {
    u64 adr;
    u8 num_endpoints;
    const struct snd_soc_acpi_endpoint *endpoints;
    const char *name_prefix;
 };

Look at her. Four members. Iconic. 💅

✨ Members ✨

• adr — a 64 bit ACPI _ADR value. Literally the device's whole address vibe check, in 64 bits of glory 🦋
• num_endpoints — how many endpoints this device has. The headcount, the roster size, the "how many besties are we talking" number 🫶
• endpoints — an array of endpoints. Pointing at the whole squad of struct snd_soc_acpi_endpoint, one after another 💜
• name_prefix — a string used for codec controls. It's the little name tag that gets stuck on the codec controls so everyone knows whose they are 🎀

That's the whole page babes, go forth and enumerate your _ADR devices with main character energy 🌈💖💅
