ppc440spe_adma_free_slots(9)

✨ NAME ✨

okay bestie, welcome to the ppc440spe_adma_free_slots(9) page from the Kernel API Manual 💅 — this one is literally about flagging descriptor slots for reuse ✨. That’s the whole lil’ mission statement, no cap.

🌸 SYNOPSIS 🌸

void ppc440spe_adma_free_slots (struct ppc440spe_adma_desc_slot *slot ,
       struct ppc440spe_adma_chan *chan );

🎀 ARGUMENTS 🎀

• slot — Slot to free. Caller must hold ppc440spe_chan->lock while calling this function. That lock requirement is the whole vibe check, bestie 🫶.
• chan — literally -- undescribed --. No invented lore, just mystery 🙈.
