ttm_kmap_ite...near_io_fini(9)

🎀 ttm_kmap_iter_linear_io_fini(9) 🎀

okay so this is a page from the Kernel API Manual, bestie — we're in kernel-land now, put your seatbelt on 💅

---

✨ NAME ✨

ttm_kmap_iter_linear_io_fini — literally just cleans up an iterator for linear io memory 🧹✨ that's it, that's the whole job

---

🌸 SYNOPSIS 🌸

void ttm_kmap_iter_linear_io_fini (struct ttm_kmap_iter_linear_io
*iter_io , struct ttm_device *bdev , struct ttm_resource *mem );

like, it returns void, so nothing comes back — it just does the thing and dips 🫶

---

🦋 ARGUMENTS 🦋

• iter_io — the iterator you're finalizing, bestie. this is the main character of the operation 👑
• bdev — the TTM device. yes, that one 💜
• mem — the ttm resource representing the iomap. icon behavior fr fr

---

💖 DESCRIPTION 💖

okay so real talk — this function is for internal TTM use only. not for you, not for me, only for TTM's private little circle 🙈

what it does: it cleans up a memcpy kmap iterator that was initialized by ttm_kmap_iter_linear_io_init. so like, ttm_kmap_iter_linear_io_init sets it up, and this one — ttm_kmap_iter_linear_io_fini — tears it down. the way that they're a matched set 😭💕

⚠️ reminder bestie: internal TTM use only. don't go calling this from your own code, i'm begging 🙏

okay that's the whole page, mwah 💋 — this gem lives in ./drivers/gpu/drm/ttm and it's dated October 2026, so mark your calendars 📅✨ slay, go clean up those iterators responsibly 🎀
