STRUCT VSP1_ISP_BUFFER_DESC(9)

💖 struct vsp1_isp_buffer_desc(9) 💖

okay so welcome to the Kernel API Manual, bestie — this is the glow-up page for struct vsp1_isp_buffer_desc, and it's literally just "describe a buffer allocated by VSPX." that's the whole vibe. one struct, three fields, main character energy. 🦋

✨ NAME ✨

struct vsp1_isp_buffer_desc — Describe a buffer allocated by VSPX. no cap, that's the job. 🎀

🌸 SYNOPSIS 🌸

struct vsp1_isp_buffer_desc {
    size_t size;
    void *cpu_addr;
    dma_addr_t dma_addr;
 };

like. look at her. three members, zero drama. 💅

👑 Members 👑

• size — the byte size of the buffer that VSPX allocated. yes, bytes, the unit of "how much of the buffer are we even talking about." 📏
• cpu_addr — the CPU-mapped address of a buffer allocated by VSPX. it's giving "your CPU's point of view." 🧠
• dma_addr — the bus address of a buffer allocated by VSPX. different address, different lane, same buffer. iykyk. 🚌

ngl bestie, keep these three straight — cpu_addr and dma_addr are not the same address in different fonts, they're genuinely different things. plot twist, but make it documented. 💀
