__fimc_pipeline_open(9)

📦 version 7.3.1, in nixpkgs unstable

✨ __fimc_pipeline_open ✨

okay so bestie, we're in the Kernel API Manual today and this one is a function called __fimc_pipeline_open — it's the lil glow-up moment where the pipeline info gets updated, power gets flipped on for all the pipeline subdevs, and the sensor clock wakes up too. like, everybody gets their power, no one's left on read 💅

🌸 SYNOPSIS 🌸

int __fimc_pipeline_open (struct exynos_media_pipeline *ep , struct
       media_entity *me , bool prepare );

that's it, that's the whole vibe check. three args, one int coming back at you ✨

🎀 ARGUMENTS 🎀

  • ep — the fimc device that terminates the pipeline. like, the end of the line, the final boss of this particular pipeline 🫶
  • me — the media entity where the graph walk kicks off. this is where we start strolling through the graph, bestie 🌈
  • prepare — the bool of destiny: pass true to walk the current pipeline and acquire all the subdevs. no shortcuts, we're collecting everyone 😭

🦋 DESCRIPTION 🦋

So the tea is: this function gets called with the graph mutex held. yes, that mutex. so don't go doing anything weird in there, okay? the lock's already taken, iykyk 🔒

ngl the source path in the footer got truncated to ./drivers/media/platform/samsu... in the original — that's literally how it was printed, so i'm not about to invent the rest of it, bestie 🙈

and that's the page!! 🍓 brought to you by that truncated ./drivers/media/platform/samsu... source path, dated October 2026 — slay, see you in the next manpage 👑💖
