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

okay so bestie, you're in the Kernel API Manual and today's main character is cvs_csi_enable_streams(9). it's giving "press play on the bridge" energy and honestly? iconic. let's get into it 🎀

✨ NAME ✨

cvs_csi_enable_streams — Start streaming through the bridge. that's it, that's the vibe. it turns the stream ON 🔥

🌸 SYNOPSIS 🌸

int cvs_csi_enable_streams (struct v4l2_subdev *sd , struct
v4l2_subdev_state *state , u32 pad , u64 streams_mask );

copy it exactly like that, no cap, don't touch the spacing, she's perfect the way she is 💖

🦋 ARGUMENTS 🦋

  • sd — the Sub-device pointer. literally the sub-device, pointing at stuff 🫶
  • state — the Active state. the state that is, yk, active ✨
  • pad — the Pad identifier. and bestie, listen, it must be ICVS_CSI_PAD_SOURCE — that's not a suggestion, that's the rule 💅
  • streams_mask — the Streams to enable. and the tea is: bit 0 supported 👑

💜 DESCRIPTION 💜

so what does she actually do? buckle up:

she Runtime-resumes the bridge — which triggers cvs_runtime_resume to claim CSI-2 link ownership (yes, claiming ownership, main character behavior fr fr). then she fetches the link frequency, programs the MIPI configuration, and forwards the enable request downstream. like a whole little relay race and she wins every leg 🏆

no skipping steps, okay? resume → fetch → program → forward. the pipeline is the pipeline 💀

🍓 RETURN 🍓

  • 0 on success 🎉
  • negative errno if it doesn't slay 😭
