STRUCT DDCB_REQU(9)

🌸 NAME 🌸

okay so bestie, struct ddcb_requ is literally the kernel's own internal glow-up of the DDCB request 💅 like, user space has its version, and this is the kernel-internal representation of the DDCB request — same request, but backstage, with main character energy.

✨ SYNOPSIS ✨

no cap, here's the whole struct, verbatim, don't touch a single character 🫶

struct ddcb_requ {
    enum genwqe_requ_state req_state;
    int num;
    struct ddcb_queue *queue;
    struct dma_mapping  dma_mappings[DDCB_FIXUPS];
    struct genwqe_sgl sgls[DDCB_FIXUPS];
    struct genwqe_ddcb_cmd cmd;
    struct genwqe_debug_data debug_data;
 };

🎀 Members 🎀

• cmd — the user space representation of the DDCB execution request 💖 it's giving "the vibe from userspace," sitting right there inside the kernel struct. iconic.
