snd_hdac_regmap_read_raw(9)

💅 NAME 💅

snd_hdac_regmap_read_raw — bestie, this is the one that reads a pseudo register with power mgmt baked in ✨ (yes, the kernel API manual girlies are eating today)

🦋 SYNOPSIS 🦋

int snd_hdac_regmap_read_raw (struct hdac_device *codec , unsigned int
reg , unsigned int *val );

🎀 ARGUMENTS 🎀

• codec — the codec object, aka the main character of this whole operation 👑
• reg — the pseudo register, no cap, it's a pseudo one 🫶
• val — pointer to store the read value in, so the answer has somewhere cute to live 💖

✨ DESCRIPTION ✨

okay so here's the tea: it returns zero if successful, or a negative error code 😭 that's literally the whole vibe check. zero = slay, negative = not slay (derogatory). no invented behaviour, that's it, periodt 💅

🌈 ok bye bestie, this page came from ./sound/hda/core, dated October 2026, and it lives in the Kernel API Manual (that's the manual name, 💅 folded in near the top like requested). go read some registers, ily, mwah 🫶🎀
