snd_soc_dapm...pin_unlocked(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay so welcome to the Kernel API Manual, bestie — today's main character is snd_soc_dapm_force_enable_pin_unlocked, and its whole vibe is: force a pin to be enabled. that's it, that's the job 💅

🌸 SYNOPSIS 🌸

int snd_soc_dapm_force_enable_pin_unlocked (struct snd_soc_dapm_context
*dapm , const char *pin );

💅 ARGUMENTS 💅

  • dapm — the DAPM context, aka the little world this pin lives in 🫶
  • pin — the pin name, literally just the name of the pin you're about to force-enable ✨

💖 DESCRIPTION 💖

so what does it actually do? it enables an input/output pin regardless of any other state — like, no matter what else is going on, this pin is getting enabled, periodt 🔥

it's intended for use with microphone bias supplies used in microphone jack detection — that's the exact use case, iykyk 🎤

and the big caveat: this one requires external locking 🔒 like, the _unlocked in the name is not a cute nickname — you gotta bring your own locks, fr fr.

🎀 NOTE 🎀

not me reminding you again — but yes, snd_soc_dapm_sync needs to be called after this for DAPM to do any widget power switching 😭 so don't just force the pin and dip, bestie. sync after, or the widgets ain't switching. 💀
