✨ drm_syncobj_find_fence(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a lil helper function from the DRM world and honestly? she's giving convenience queen. let's get into it 🎀

---

🌸 NAME 🌸

drm_syncobj_find_fence — lookup and reference the fence in a sync object 🦋

---

💅 SYNOPSIS 💅

int drm_syncobj_find_fence (struct drm_file *file_private , u32 handle ,
u64 point , u64 flags , struct dma_fence **fence );

like, that's the whole vibe right there ✨

---

🧚 ARGUMENTS 🧚

• file_private — the drm file private pointer, aka the lil context thing you hand over 🙈
• handle — the sync object handle to look up. this is the one you're hunting for, iykyk 🔍
• point — the timeline point ⏳
• flags — DRM_SYNCOBJ_WAIT_FLAGS_WAIT_FOR_SUBMIT or not. that's literally the choice, no cap 🫶
• fence — the out parameter for the fence, where the good stuff lands 📥

---

🔥 DESCRIPTION 🔥

so basically this is just a convenience function that combines drm_syncobj_find and drm_syncobj_fence_get — like a two-for-one combo meal, obsessed 🍓

it returns 0 on success, or a negative error value on failure 😭 and here's the important bit, bestie: on success, fence contains a reference to the fence, and you must release it by calling dma_fence_put. don't leave her hanging, that's a leak and it's not cute 💀
