ttm_tt_is_swapped(9)

✨ ttm_tt_is_swapped(9) ✨

okay so this is a page straight out of the Kernel API Manual, and it's lowkey one of the smallest pages ever but it's still kinda iconic? it's literally just vibes + one little bool 💅 no cap, we're checking a status here, nothing more.

---

🌸 NAME 🌸

ttm_tt_is_swapped — tells you whether the ttm_tt is swapped out or backed up 🫶

like, that's the whole job. it's a vibe check for a ttm_tt. periodt.

---

🦋 SYNOPSIS 🦋

bool ttm_tt_is_swapped (const struct ttm_tt *tt );

it returns a bool, it takes one const struct ttm_tt * named tt, and no, it's not gonna touch your stuff — it's const, bestie, it's just looking 👀✨

---

🎀 ARGUMENTS 🎀

• tt — the struct ttm_tt. that's it. that's the whole argument. hand it the struct and let it cook 🍓

---

🌈 RETURN 🌈

• true — if it's swapped or backed up 💀 (in a good way)
• false — otherwise 🙈

binary queen. two outcomes only, no in-between, we love a decisive function 👑

⭐ SEE ALSO ⭐

okay this is where it gets fun, because there's a whole little ttm_tt friend group and you will be meeting them 🧚‍♀️ they all live in the kernel file ./include/drm/ttm/ttm_tt.h:

• struct ttm_tt(9) — the main character itself fr fr
• struct ttm_kmap_iter_tt(9)
• ttm_tt_is_backed_up(9)
• ttm_tt_clear_backed_up(9)
• ttm_tt_create(9)
• ttm_tt_init(9)

• struct ttm_backup_flags(9)
• ttm_agp_tt_create(9)

iykyk. go read them, they're all part of the same squad 💜

ngl the whole page is basically "ask the struct if it's swapped" and honestly? sometimes that's enough. not every manpage needs to be a whole saga ✨
