STRUCT XILINX_CDMA_DESC_HW(9)

💅 struct xilinx_cdma_desc_hw(9) — Kernel API Manual, bestie ✨

okay so this is the Kernel API Manual page for struct xilinx_cdma_desc_hw(9), and it’s giving hardware descriptor but make it a whole struct. No cap. If you’re in the Xilinx DMA corner of the kernel, this is your little card. 💖

🌸 NAME

struct xilinx_cdma_desc_hw — Hardware Descriptor. That’s the whole vibe: it’s the hardware descriptor struct. 🎀

✨ SYNOPSIS

struct xilinx_cdma_desc_hw {
    u32 next_desc;
    u32 next_desc_msb;
    u32 src_addr;
    u32 src_addr_msb;
    u32 dest_addr;
    u32 dest_addr_msb;
    u32 control;
    u32 status;
};

🧚 Members (the whole cast, with offsets) 💅

• next_desc — Next Descriptor Pointer, at offset 0x00. The pointer to the next descriptor, living its best life at the very top. 👑
• next_desc_msb — Next Descriptor Pointer MSB, at offset 0x04. The MSB half of that next-descriptor pointer, highkey important. ⭐
• src_addr — Source address, at offset 0x08. The source address field, periodt. 🌈
• src_addr_msb — Source address MSB, at offset 0x0C. The most significant bits for the source address. ✨
• dest_addr — Destination address, at offset 0x10. Destination address, front and center. 🎯
• dest_addr_msb — Destination address MSB, at offset 0x14. Destination address’s MSB half. 🦋
• control — Control field, at offset 0x18. The control field. It’s giving control. 💅
• status — Status field, at offset 0x1C. The status field, last but never least. 🌸
