snd_hda_override_conn_list(9)

💖 NAME 💖

okay bestie, welcome to the snd_hda_override_conn_list(9) page — the vibe is add/modify the connection-list to cache, and honestly it’s giving main-character cache energy ✨

🌸 SYNOPSIS 🌸

int snd_hda_override_conn_list (struct hda_codec *codec , hda_nid_t nid
, int len , const hda_nid_t *list );

No cap, that’s the whole signature 🫶

🎀 ARGUMENTS 🎀

• codec — the HDA codec 🎧
• nid — NID to parse 🔍
• len — number of connection list entries 🔢
• list — the list of connection entries 📝

✨ DESCRIPTION ✨

So here’s the tea: this function adds or modifies the given connection-list in the cache. If the corresponding cache already exists, it invalidates it and appends a new one. Literally that’s the whole move 💅

Returns zero or a negative error code. Periodt.

Kernel file: ./sound/hda/common/codec.c — that’s the spot 👑
