snd_soc_add_pcm_runtime(9)

✨ snd_soc_add_pcm_runtime(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one's a little function from ./sound/soc that does exactly what its name says, and honestly? it's giving "small but mighty" 💅

🌸 NAME 🌸

snd_soc_add_pcm_runtime — the girl that adds a pcm_runtime dynamically via dai_link, no cap 🫶

⭐ SYNOPSIS ⭐

int snd_soc_add_pcm_runtime (struct snd_soc_card *card , struct
snd_soc_dai_link *dai_link );

like, that's the whole signature, keep it exactly like that pls 😭

🎀 ARGUMENTS 🎀

• card — the ASoC card that the pcm_runtime gets added to. it's the main character here 👑
• dai_link — the DAI link we use to find the pcm_runtime. iykyk

🦋 DESCRIPTION 🦋

so basically this function adds a pcm_runtime to an ASoC card, and it does it by using dai_link. that's it, that's the vibe. lowkey elegant, fr fr ✨

💜 NOTE 💜

bestie, write this one down 📝

Topology can use this API to add pcm_runtime when it's probing the topology component. and machine drivers? they can still define static DAI links in the dai_link array. both things, no conflict, we love to see it 💖
