dma_resv_init(9)

✨ dma_resv_init(9) ✨

okay so bestie, welcome to the Kernel API Manual — this is dma_resv_init(9) and it's literally the glow-up ritual for a reservation object. like, the "getting ready" montage but for kernel structs 💅

---

🎀 NAME 🎀

dma_resv_init — bestie, it initializes a reservation object. that's the whole vibe. it sets it up. it makes it ready. periodt.

---

🌸 SYNOPSIS 🌸

void dma_resv_init (struct dma_resv *obj );

no cap, that's the whole signature. returns void — nothing to catch, nothing to check, it just does the thing 🦋

---

🧚 ARGUMENTS 🧚

• obj — the reservation object in question. that's your main character right there 👑 you hand it over and it gets initialized. iconic behavior honestly.

💜 SEE ALSO 💜

okay this is the friend group, the whole crew, the group chat roster 🫶 all of these live in the kernel file ./drivers/dma-buf/dma-resv.c, and you should absolutely go read Reservation Object Overview(9) first if you want the lore:

• dma_resv_fini(9) — the breakup counterpart, the cleanup 😭
• dma_resv_reserve_fences(9)
• dma_resv_reset_max_fences(9)
• dma_resv_add_fence(9)
• dma_resv_replace_fences(9)
• dma_resv_iter_first_unlocked(9)
• dma_resv_iter_next_unlocked(9)
• dma_resv_iter_first(9)
• dma_resv_iter_next(9)
• dma_resv_copy_fences(9)
• dma_resv_get_fences(9)
• dma_resv_get_singleton(9)
• dma_resv_wait_timeout(9)
• dma_resv_set_deadline(9)
• dma_resv_test_signaled(9)
• dma_resv_describe(9)

ngl, if you call dma_resv_init you are lowkey signing up to eventually call dma_resv_fini(9) too. that's the circle of life, bestie 🌈
