snd_hdac_bus...e_stream_irq(9)

✨ NAME ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this page is all about snd_hdac_bus_handle_stream_irq , and what it does is literally the interrupt handler for streams. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int snd_hdac_bus_handle_stream_irq (struct hdac_bus *bus , unsigned int
status , void (*ack)(struct hdac_bus *, struct hdac_stream *) );

that's the signature, no cap — copy it exactly, don't get creative with it 🫶

---

🦋 ARGUMENTS 🦋

• bus — the HD-audio core bus, your main character ✨
• status — the INTSTS register value. yes, that one. 💅
• ack — a callback that gets called for the woken streams — like a little "hey you're up" tap on the shoulder 🌸

---

💜 DESCRIPTION 💜

so what does it actually do?? it returns the bits of handled streams, or zero if no stream is handled. that's it, that's the whole function, and honestly? iconic. 💀✨
