to_pvr_queue_job_fence(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 NAME 🎀

okay so bestie, welcome to the Kernel API Manual 💖 — this page is all about to_pvr_queue_job_fence(9), and honestly? it's giving "little helper that knows exactly who's who at the party." 🦋

to_pvr_queue_job_fence — Return a pvr_queue_fence object if the fence is already backed by a UFO. 👽✨

✨ SYNOPSIS ✨

struct pvr_queue_fence * to_pvr_queue_job_fence (struct dma_fence *f );

🌸 ARGUMENTS 🌸

  • f — the dma_fence you wanna turn into a pvr_queue_fence. that's the whole input, bestie, no hidden extras 💅

💅 DESCRIPTION 💅

so like, this function could be called on a few different things, and it handles each one differently depending on the vibe check it gets 👑

  • a job fence, directly — in which case it simply returns the containing pvr_queue_fence. easy, no cap, it just hands you the thing 🫶
  • a drm_sched_fence's scheduled or finished fence — in which case it will first try to follow the parent pointer to find the job fence. ⚠️ important caveat, bestie: note that the parent pointer is initialized only after the run_job callback is called on the drm_sched_fence's owning job. so like, timing matters, fr fr 😭
  • any other dma_fence — in which case it will return NULL. not every fence is main character energy, and that's fine 💀

🔥 RETURN 🔥

  • A non-NULL pvr_queue_fence object if the dma_fence is backed by a UFO 👽, or
  • NULL otherwise 🙈
