STRUCT TTM_KMAP_ITER_LINEAR_IO(9)

okay so bestie, welcome to the Kernel API Manual page for struct ttm_kmap_iter_linear_io(9) — yes, the title is a whole keyboard smash, but it's literally about an iterator specialization and it's lowkey iconic. 💅✨

🌸 NAME 🌸

struct ttm_kmap_iter_linear_io — Iterator specialization for linear io. That's the whole name, no cap. 🫶

✨ SYNOPSIS ✨

quick vibe check: here's the struct, exactly as it's defined. don't touch the spelling, bestie. 😭

struct ttm_kmap_iter_linear_io {
    struct ttm_kmap_iter base;
    struct iosys_map dmap;
    bool needs_unmap;
};

🎀 Members 🎀

• base — the base iterator. literally the foundation of this whole situation. 🧚
• dmap — points to the starting address of the region. think "first stop on the map" energy. 🗺️
• needs_unmap — whether we need to unmap on fini. so on fini, this bool is the vibe check. 🙈

🌈 SEE ALSO 🌈

Kernel file: ./include/drm/ttm/ttm_resource.h — go read the source, bestie, it's giving main character documentation. 📚
