🎀 snd_hda_pick_pin_fixup(9) 🎀

okay so real talk, bestie — you're reading a page out of the Kernel API Manual, and it's about snd_hda_pick_pin_fixup. yes it's a nine. yes that means kernel-space. no you cannot just malloc your way out of this one 💅

✨ NAME ✨

snd_hda_pick_pin_fixup — the function that picks up a fixup matching with the pin quirk list 🫶

like, it literally goes shopping through the quirk list and comes back with the fixup that matches. iconic behavior honestly

🌸 SYNOPSIS 🌸

void snd_hda_pick_pin_fixup (struct hda_codec *codec , const struct
snd_hda_pin_quirk *pin_quirk , const struct hda_fixup *fixlist , bool
match_all_pins );

no return value, it's a void, she just does her thing and leaves ✨

🦋 ARGUMENTS 🦋

  • codec — the HDA codec 💖 this is the main character of the whole operation, the device we're out here fixing up
  • pin_quirk — zero-terminated pin quirk list 🎀 yes, zero-terminated, so she knows where to stop — no cap, don't be out here forgetting your terminator
  • fixlist — the fixup list ⭐ the menu of fixups we're picking from
  • match_all_pins — all valid pins must match with the table entries 👑 so if this is set, it's giving "every single pin has to agree," not "one match and we're done." strict queen energy

lowkey reminder: this is kernel API documentation, so everything above is fr fr the actual contract — the arguments, the types, the terminator, all of it. no guessing, no vibes-based programming 🙈

mwah 💋 that's the whole page! and for the record, this lil masterpiece comes from ./sound/hda/common and it's dated October 2026 — so yeah, she's from the future, slay ⭐🌈👑
