STRUCT VMW_SG_TABLE(9)

💖 struct vmw_sg_table(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for struct vmw_sg_table — this is the scatter/gather table you use for binding, except it's got extra device-specific info tucked in. it's giving "sg_table but make it vmwgfx" ✨

---

🌸 NAME 🌸

struct vmw_sg_table — the scatter/gather table for binding, with additional device-specific information. literally what it says on the tin, no cap 🫶

---

🎀 SYNOPSIS 🎀

struct vmw_sg_table {
    enum vmw_dma_map_mode mode;
    struct page **pages;
    const dma_addr_t *addrs;
    struct sg_table *sgt;
    unsigned long num_pages;
 };

---

🦋 Members 🦋

• mode — which page mapping mode to use. the main character of this struct ngl 💅
• pages — array of page pointers to the pages.
• addrs — DMA addresses to the pages, but only if coherent pages are used. conditional queen 👑
• sgt — pointer to a struct sg_table that's holding the binding information.
• num_pages — number of pages. the count. the receipts. 🔥
