💅 struct ttm_bo_evict_walk(9)

okay so bestie, welcome to the Kernel API Manual ✨ this one's all about struct ttm_bo_evict_walk — literally the parameters for the evict walk. no cap, that's the whole vibe.

🌸 NAME 🌸

struct ttm_bo_evict_walk — Parameters for the evict walk. that's it, that's the tweet 🫶

✨ SYNOPSIS ✨

struct ttm_bo_evict_walk {
    struct ttm_lru_walk walk;
    const struct ttm_place *place;
    struct ttm_buffer_object *evictor;
    struct ttm_resource **res;
    unsigned long evicted;
    bool try_low;
    bool hit_low;
    struct ttm_bo_alloc_state *alloc_state;
 };

look at her. iconic struct. 🎀

🦋 Members 🦋

here's the cast of characters, and honestly? every single one of them eats 💅

  • walk — the walk base parameters. the foundation, the main character energy, the whole starting point fr.
  • place — the place that gets passed to the resource allocation. where we're tryna be, lowkey.
  • evictor — the buffer object we're literally trying to make room for. king behaviour honestly, everything else is getting moved for you 👑
  • res — the allocated resource, if any. and yes bestie, "if any" is doing a lot of work in that sentence 🙈
  • evicted — the number of successful evictions. a little counter, a little trophy case, we love to see it.
  • try_low — whether we should attempt to evict BO's with low watermark threshold. like, should we go for the low ones? that's the question 🫶
  • hit_low — if we cannot evict a bo when try_low is false (first pass). so like, the first-pass drama, noted 💀
  • alloc_state — state associated with the allocation attempt. keeping receipts on the whole allocation moment, periodt.

okay that's the whole manpage, mwah, go forth and evict responsibly 🧚💖
