psc_dma_bcom..._next_buffer(9)

💖 psc_dma_bcom_enqueue_next_buffer — bestie's kernel API manual (section 9) 💖

okay so this is a page straight out of the Kernel API Manual, section 9, and it's lowkey one of those tiny functions that does exactly one thing and does it slay. no cap. let's get into it 🫶

---

✨ NAME ✨

psc_dma_bcom_enqueue_next_buffer — literally just enqueues another audio buffer. that's it. that's the whole job 💅

---

🌸 SYNOPSIS 🌸

void psc_dma_bcom_enqueue_next_buffer (struct psc_dma_stream *s );

like… she takes one pointer and returns nothing. void. no notes. iconic behaviour honestly ✨

---

🎀 ARGUMENTS 🎀

• s — pointer to the stream private data structure 💫 (yes bestie, it's a struct psc_dma_stream *, the private-data one, keep up 🦋)

---

🔥 DESCRIPTION 🔥

so what she actually does: she enqueues another audio period buffer into the bestcomm queue. that's the vibe. one more buffer, shoved into the queue, ready to go 🎧✨

not me being obsessed with how simple that is. main character energy fr fr 👑

---

💀 NOTE 💀

okay this is the important part, do not skip it 🙈

The routine must only be called when there is space available in the queue. Otherwise the enqueue will fail and the audio ring buffer will get out of sync.

like… if you call her when the queue is full, she will fail and your audio ring buffer is gonna be out of sync — and that is a whole mess you do not want 😭 so vibe check the queue first, bestie. periodt.

mwah 💋 that's a wrap! this lil beauty lives under ./sound/soc/fsl, dated October 2026, and the footer still says psc_dma_bcom..._next_buffer(9) on both sides — she's consistent, she's cute, she's done. 🍓🧚💖
