💖 dma_pool_zalloc(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes this is that dma_pool_zalloc(9) page, the one you've been scrolling past. sit down, hydrate, let's get into it 🫶

✨ NAME ✨

dma_pool_zalloc — get a zero-initialized block of DMA coherent memory. it's giving "allocation but make it clean" 💅

---

🌸 SYNOPSIS 🌸

void * dma_pool_zalloc (struct dma_pool *pool , gfp_t mem_flags ,
       dma_addr_t *handle );

literally that's the whole call, no cap.

---

🎀 ARGUMENTS 🎀

• pool — the dma pool that will produce the block. it's the main character here, it's the one handing out the memory 👑
• mem_flags — a GFP_* bitmask. you know the drill, flags go here 🌈
• handle — pointer to the dma address of the block. so it can tell you where the thing landed 📍

---

🦋 DESCRIPTION 🦋

same as dma_pool_alloc, but the returned memory is zeroed. that's it, that's the whole personality — it's the identical twin of dma_pool_alloc except this one shows up with a clean slate ✨ zeroed memory, no leftover vibes, periodt.
