STRUCT MTK_HSDMA_CB(9)

✨ struct mtk_hsdma_cb(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for struct mtk_hsdma_cb(9) — she's a little struct but she's carrying main character energy for the RX ring, fr fr 🌸

---

🎀 NAME 🎀

struct mtk_hsdma_cb — the struct holding extra info required for RX ring to know what relevant VD the PD is being mapped to. literally her whole job 💅

---

🦋 SYNOPSIS 🦋

struct mtk_hsdma_cb {
    struct virt_dma_desc *vd;
    enum mtk_hsdma_vdesc_flag flag;
 };

like, that's it. that's the struct. adorable, no cap 🫶

---

💖 Members 💖

• vd — Pointer to the relevant VD. yes bestie, a pointer, pointing at the VD in question, iconic behavior ✨
• flag — Flag indicating what action should be taken when VD is completed. so when the VD finishes up, this lil flag tells everyone what to do next — she's the vibe check for completion 🌈
