💖 __i915_active_fence_init 💖

okay so this is a page from the Kernel API Manual (yes bestie, the kernel, we're in the big leagues now 👑) and it's all about getting an activity tracker ready to, like, exist. let's get into it ✨

---

✨ NAME ✨

__i915_active_fence_init — literally prepares the activity tracker for use 🎀

---

🦋 SYNOPSIS 🦋

void __i915_active_fence_init (struct i915_active_fence *active , void
*fence , dma_fence_func_t fn );

---

💅 ARGUMENTS 💅

• active — the active tracker itself, the main character of this whole function 🫶
• fence — the initial fence to track, and it can be NULL (no cap, NULL is valid here)
• fn — a callback that fires when the tracker is retired (aka when it becomes idle), and it can be NULL too 🙈

---

🌸 DESCRIPTION 🌸

so i915_active_fence_init prepares the embedded active struct for use as an activity tracker — meaning it's the thing that keeps tabs on the last known active fence associated with it. like, that's its whole job. it's giving record-keeper energy 💀

and when the last fence becomes idle — which happens when it's retired after completion — the optional callback func gets invoked. the way that works is genuinely iconic ngl ✨
