virtsnd_pcm_period_elapsed(9)

🌸 NAME 🌸

virtsnd_pcm_period_elapsed — from the Kernel API Manual, bestie: the Kernel work function to handle the elapsed period state. 💖

---

✨ SYNOPSIS ✨

void virtsnd_pcm_period_elapsed (struct work_struct *work );

That's the signature, and yes, the spacing is part of the look. Slay. 💅

---

🎀 ARGUMENTS 🎀

• work — the elapsed period work. That's the thing getting passed in, periodt. ✨

---

🦋 DESCRIPTION 🦋

The main purpose of this function is to call snd_pcm_period_elapsed in a process context, not in an interrupt context. That's literally the whole assignment, no cap. 🫶

This is necessary because PCM devices operate in non-atomic mode. So yeah, context matters — it's giving very "process context only, bestie." 😭✨

---

🌈 CONTEXT 🌈

Process context. That's the vibe check — this one belongs in process context. 💅
