i915_deps_add_resv(9)

💅 i915_deps_add_resv(9) 💅

okay so bestie, welcome to the i915_deps_add_resv page — this is a Kernel API Manual situation, and honestly? it's a little baby function with a big job. it grabs fences and shoves them into your dependency collection. iconic behavior, no notes. 🦋

---

✨ NAME ✨

i915_deps_add_resv — Add the fences of a reservation object to a dependency collection. that's literally it. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int i915_deps_add_resv (struct i915_deps *deps , struct dma_resv *resv ,
const struct ttm_operation_ctx *ctx );

look at those three little params holding hands 🫶 copy them exactly, okay? commas and spacing and all. the compiler does not care about your aesthetic. 💀

👑 ARGUMENTS 👑

• deps — Pointer to the i915_deps structure a fence is to be added to. this is the collection, the little basket you're dropping fences into. main character energy fr fr. 🧺
• resv — The reservation object, then fences of which to add. yes, "then fences of which to add" — that's the page's grammar, not mine, i'm just the messenger 🙈 this is your source of fences.
• ctx — Pointer to a struct ttm_operation_ctx indicating how waits are to be performed if waiting. iykyk — this is the "how do we wait, if we're waiting" manual. 💅

---

🦋 DESCRIPTION 🦋

Calls i915_deps_add_depencency on the indicated fences of resv.

and yes, i915_deps_add_depencency is spelled exactly like that on the page — extra "enc" and all. don't come for me, i'm just transcribing the icon ✨ (the real one you're thinking of is over in SEE ALSO, mind the spelling there too 👀).

so like: take the fences marked out on resv, hand each one to that function, and they land in your deps collection. that's the whole plot. short page, short function, highkey slay. 🎀

🔥 RETURN 🔥

• Zero on success. 🟢
• Negative error code on error. 🔴

bestie please actually check this one. a negative return is not a vibe, it's a signal that something went sideways. do not ignore it. 😭

and that's the page, bestie!! 🌸 this little darling lives in ./drivers/gpu/drm/i915, and the page itself is dated October 2026 — so go forth, add those fences, check those return codes, and stan a well-documented dependency collection. 💖✨👑
