pvr_queue_prepare_job(9)

📦 version 7.3.1, in nixpkgs unstable

💅 pvr_queue_prepare_job(9) — the Kernel API Manual glow-up ✨

okay so we're in the Kernel API Manual today bestie, and the main character is pvr_queue_prepare_job(9). she's a little function with one job (literally) and she eats every time 🫶

🌸 NAME 🌸

pvr_queue_prepare_job — hand back the next internal dependencies, all dressed up as a dma_fence.

like yes, the next ones. one at a time. she's not gonna dump the whole list on you 💅

✨ SYNOPSIS ✨

struct dma_fence * pvr_queue_prepare_job (struct drm_sched_job
*sched_job , struct drm_sched_entity *s_entity );

that's it, that's the whole vibe. two args in, one struct dma_fence * out 🔥

🎀 ARGUMENTS 🎀

  • sched_job — the job we're asking about, aka "which internal dependency comes next, bestie?" 👀
  • s_entity — the entity this job is queued on. yes, that's queue on, that's what the page says, we don't argue with the page 🫡

💖 DESCRIPTION 💖

okay so picture this: drm_sched has already done its little loop over drm_sched_job::dependencies, right? and then it's like "hey driver, you got anything of your own to add?" and that is literally where we come in 🦋

we use this function to return our internal dependencies. that's the whole thing. not me being obsessed with a callback but here we are 😭

no cap, that's the entire description. short queen energy 👑
