💅 pvr_queue_get_job_kccb_fence — Kernel API Manual ✨

okay so bestie, welcome to the pvr_queue_get_job_kccb_fence(9) page — this is a Kernel API Manual entry and it's honestly so much easier than the name makes it look, i promise 🫶

---

🌸 NAME 🌸

pvr_queue_get_job_kccb_fence — get the KCCB fence that's attached to a job. that's it. that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

struct dma_fence * pvr_queue_get_job_kccb_fence (struct pvr_queue *queue
, struct pvr_job *job );

like, you hand it a queue and a job, and it hands you back a struct dma_fence *. slay 💅

---

🦋 ARGUMENTS 🦋

• queue — the queue this job is gonna be submitted to. that's the one, bestie 👑
• job — the job we're getting the KCCB fence on. main character energy fr fr ✨

---

💖 DESCRIPTION 💖

so the KCCB fence is a synchronization primitive — iconic behaviour honestly — and its whole thing is letting us delay job submission until there's enough space in the KCCB to actually submit the job 🌈

the way that works: if the KCCB is full, we don't just barge in, we wait our turn like a polite little fairy 🧚 it's giving patience, it's giving synchronization, it's giving no cap 💜

---

⭐ RETURN ⭐

• NULL — if there's enough space in the KCCB to submit this job 🍓 (you're good, go ahead)
• a valid dma_fence object — otherwise 😭 (wait your turn bestie)
