okay so this is a page from the Kernel API Manual (gsi_trans_pool_alloc_dma(9)), and honestly it's short and sweet — we love a low-effort icon 🎀

🌸 NAME 🌸

gsi_trans_pool_alloc_dma — allocate an element from a DMA pool. that's it, that's the whole vibe 🫶

---

✨ SYNOPSIS ✨

void * gsi_trans_pool_alloc_dma (struct gsi_trans_pool *pool ,
dma_addr_t *addr );

---

🦋 ARGUMENTS 🦋

• pool — the DMA pool pointer, aka where you're grabbing the element from 💖
• addr — the DMA address "handle" that comes along with the allocation. lowkey it's the element's little name tag 🏷️

---

👑 RETURN 👑

the virtual address of the element you just allocated out of the pool. slay, you got a pointer ✨

---
