pvr_queue_ge...b_cccb_fence(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

ok so bestie, welcome to the Kernel API Manual, section 9 — this is pvr_queue_get_job_cccb_fence ✨ and it does exactly one iconic thing: it gets the CCCB fence that's attached to a job. that's it, that's the whole vibe 🎀

🔥 SYNOPSIS 🔥

struct dma_fence * pvr_queue_get_job_cccb_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 *, no cap 🫶

🌸 ARGUMENTS 🌸

  • queue — the queue this job is gonna be submitted to. yes, this queue. the one it belongs to 💖
  • job — the job whose CCCB fence you're trying to get. the main character of this function call, honestly 👑

🦋 DESCRIPTION 🦋

okay so picture this: the CCCB fence is a synchronization primitive — and the way that it works is it lets us delay job submission until there's enough space in the CCCB to actually submit the job. it's giving "bestie hold on, wait for your turn" energy 😭✨

it's literally just a little fence that says "not yet, not yet… okay NOW" 💅

⭐ RETURN ⭐

so what do you get back? two possibilities, and only two:

  • NULL if there's enough space in the CCCB to submit this job — slay, you're good to go 💖
  • a valid dma_fence object otherwise — i.e. nope, not yet, the fence is telling you to chill 🙈
