💅 ttm_kmap_iter_tt_init(9) — the kernel API manual, bestie edition 🎀

okay so this is the page for ttm_kmap_iter_tt_init, straight out of the Kernel API Manual (section 9, iykyk). it's a short one and honestly she's iconic for it ✨

🌸 NAME 🌸

ttm_kmap_iter_tt_init — literally just initialize a struct ttm_kmap_iter_tt 🫶 that's the whole job. that's the assignment.

✨ SYNOPSIS ✨

struct ttm_kmap_iter * ttm_kmap_iter_tt_init (struct ttm_kmap_iter_tt
*iter_tt , struct ttm_tt *tt );

no cap, that's the exact signature — copy it character for character or she will not compile 💀

🦋 ARGUMENTS 🦋

  • iter_tt — the struct ttm_kmap_iter_tt you're initializing bestie 💖 this is the one getting the glow-up.
  • tt — a struct ttm_tt that's holding the page pointers of the struct ttm_resource. she's carrying the pages, she's main character energy 👑

⭐ RETURN ⭐

you get back a pointer to the embedded struct ttm_kmap_iter 🎀 so like... it's embedded, and you get the pointer to it. periodt.

go look at the kernel file ./drivers/gpu/drm/ttm/ttm_tt.c and also these three besties, they're all in the group chat together:

🫶 friendly reminder: all the flags, args and function names above are verbatim — do not "fix" them, do not rename them, the kernel does not accept vibes-based refactors 😭

and that's the page!! 💜 this one lives down in ./drivers/gpu/drm/ttm, dated October 2026, under the very cute name ttm_kmap_iter_tt_init(9) — mwah, go forth and initialize your iterators 🌸💅🍓
