💖 pvr_queue_fence_is_native(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a lil' function from the Imagination GPU driver and it is, lowkey, doing a whole vibe check on your fences. Let's get into it 🫶

🌸 NAME 🌸

pvr_queue_fence_is_native — the girl whose entire job is checking whether a dma_fence is native to this driver 💅 fr fr, that's it, that's the whole plot.

✨ SYNOPSIS ✨

bool pvr_queue_fence_is_native (struct dma_fence *f );

🎀 ARGUMENTS 🎀

  • f — the fence we're testing. yes literally just hand her a fence and she'll tell you what's up 💖

🦋 DESCRIPTION 🦋

So the way this works: you pass in a fence, and she checks if it's a drm_sched_fence that's actually coming from this driver. Not some random other driver's fence trying to sneak into the group chat — ours. periodt. 👑

And here's the cute part — it might be a UFO-backed fence, iykyk. Meaning a fence that can be signaled or waited upon FW-side. Think pvr_job::done_fence objects, which are backed by the timeline UFO attached to the queue they get pushed to 🌈⭐

So yeah, she's out here doing important work, no cap 😭
