drm_sched_job_done_cb(9)

✨ drm_sched_job_done_cb ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's a tiny little kernel page — like, one function, two arguments, and then a SEE ALSO list that absolutely ate and left no crumbs 👑

---

💖 NAME 💖

drm_sched_job_done_cb — literally the callback for a done job 🎀

---

🦋 SYNOPSIS 🦋

void drm_sched_job_done_cb (struct dma_fence *f , struct dma_fence_cb
*cb );

no cap, that's the whole signature. it returns void, so don't go looking for a return value, there isn't one, periodt ✨

---

🌸 ARGUMENTS 🌸

• f — fence 🧚 like, the struct dma_fence * fence. that's it, that's the whole description.
• cb — fence callbacks 💫 the struct dma_fence_cb *, i.e. the callback struct.

ngl the original page is extremely chill about describing these two. it just says "fence" and "fence callbacks" and dips 😭 so i'm not gonna sit here and invent lore that isn't in the doc — iykyk 🫶

---

🔥 SEE ALSO 🔥

okay this is the main character section fr fr. the kernel file is ./drivers/gpu/drm/scheduler/sched_main.c — go read it, it's giving source of truth 🌈

🎀 the cute sign-off 🎀

this page lives in ./drivers/gpu/drm/scheduler, it's dated October 2026, and yes the header/footer kept saying drm_sched_job_done_cb(9) the whole time because that's the name, slay. anyway go call your callback when the job is done bestie, ily, bye 🫶💖⭐
