i915_deps_sync(9)

💅 i915_deps_sync — the Kernel API Manual moment 💅

okay bestie, buckle up, because this is i915_deps_sync(9) and it's basically the "wait for everybody in the group chat to finish typing" of the kernel 💖

✨ NAME ✨

i915_deps_sync — wait for all the fences in the dependency collection 🎀

---

🌸 SYNOPSIS 🌸

int i915_deps_sync (const struct i915_deps *deps , const struct
       ttm_operation_ctx *ctx );

---

🦋 ARGUMENTS 🦋

• deps — pointer to the i915_deps structure, like, specifically the one whose fences you're waiting on. that's the whole assignment, no cap 👑
• ctx — pointer to a struct ttm_operation_ctx, and it's the one telling us how the waits should be performed. it's giving "set the vibe for the waiting" ngl ✨

---

💜 DESCRIPTION 💜

so the way this works: this function waits for fences in the dependency collection. iconic behaviour, honestly 🫶

but here's the plot twist 😭 — if it encounters an error during the wait, or a fence error, then the wait for further fences is aborted and the error gets returned. like it's not gonna sit around waiting on the rest of them, it's closing the app and going home 💀

bestie please note: it aborts the whole thing and hands you back the error. no silent suffering, we love a clean exit 💅

---

⭐ RETURN ⭐

• Zero if successful 🌈
• Negative error code on error 💀
