STRUCT HANTRO_AUX_BUF(9)

✨ struct hantro_aux_buf(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 and today's main character is struct hantro_aux_buf — literally just an auxiliary DMA buffer for hardware data 🎀 like that's the whole vibe.

---

🌸 NAME 🌸

struct hantro_aux_buf — auxiliary DMA buffer for hardware data ✨ no cap, that's it, that's the girl.

---

🦋 SYNOPSIS 🦋

ok so here's the whole struct, copied exactly, do not touch the formatting or she will come for you:

struct hantro_aux_buf {
    void *cpu;
    dma_addr_t dma;
    size_t size;
    unsigned long attrs;
 };

---

👑 Members 👑

• cpu — the CPU pointer to the buffer. like, the vibe from the CPU's point of view 🫶
• dma — the DMA address of the buffer. bestie's other address, the device-facing one 💫
• size — size of the buffer. yes it's the size, we been knew 💅
• attrs — the attributes of the DMA mapping. the little personality traits of the mapping, iykyk ✨
