STRUCT TTM_BO_SWAPOUT_WALK(9)

💅 struct ttm_bo_swapout_walk(9) — Kernel API Manual

okay bestie, welcome to the Kernel API Manual for struct ttm_bo_swapout_walk ✨ this one's short and sweet, so grab your lil boba and let's get into it 🧋🫶

🌸 NAME 🌸

struct ttm_bo_swapout_walk — literally just the parameters for the swapout walk, no cap 💅

✨ SYNOPSIS ✨

struct ttm_bo_swapout_walk {
    struct ttm_lru_walk walk;
    gfp_t gfp_flags;
    bool hit_low, evict_low;
 };

look at her, she's iconic 🎀

🦋 Members 🦋

• walk — the walk base parameters. the foundation, the main character energy 👑
• gfp_flags — the gfp_flags to use for ttm_tt_swapout. yes bestie, those flags 🌈
• hit_low — whether we should attempt to swap BO's with low watermark threshold. like, should we even try with the low ones? 🙈
• evict_low — if we cannot swap a bo when try_low is false (first pass). so like, plan B behaviour, iykyk 💀
