STRUCT TEGRA_CSI_OPS(9)

💅 struct tegra_csi_ops(9) — Tegra CSI operations 💅

okay bestie, so this is a page straight out of the Kernel API Manual, and it's all about struct tegra_csi_ops — the operation table for Tegra CSI stuff. it's short, it's sweet, and it's literally the blueprint for how the CSI driver talks to the hardware. let's get into it 🎀

---

✨ NAME ✨

struct tegra_csi_ops — Tegra CSI operations. that's it, that's the whole vibe. it's a struct full of function pointers and it runs the show for CSI streaming. periodt 🫶

---

🌸 SYNOPSIS 🌸

here's the shape of it, character for character, no cap:

struct tegra_csi_ops {
    int (*csi_start_streaming)(struct tegra_csi_channel *csi_chan);
    void (*csi_stop_streaming)(struct tegra_csi_channel *csi_chan);
    void (*csi_err_recover)(struct tegra_csi_channel *csi_chan);
 };

three function pointers, each one taking a struct tegra_csi_channel *csi_chan. notice the first one returns an int and the other two return void — that's not a typo, that's just how it is 💀

🦋 Members 🦋

okay so let's meet the members one by one, they're all kinda iconic in their own way:

• csi_start_streaming — this one programs the csi hardware to enable streaming. it's the "go go go" button 🏁 and it returns an int, so it can tell you how it went.
• csi_stop_streaming — programs the csi hardware to disable streaming. the "ok we're done here" button, returns void, no notes 💅
• csi_err_recover — this is the glow-up/repair era 🧚 it does csi hardware block recovery in case of any capture errors. and when do those happen? the page says it's due to a missing source stream or due to improper csi input from the external source. so basically when the input situation is a mess, this bad boy recovers the hardware block. returns void, of course.

ngl, if you're implementing these, remember: the descriptions above are exactly the behaviour the manual gives you — don't go inventing extra magic and then blaming me 🙈

• struct tegra_csi_channel(9)
• struct tpg_framerate(9)
• struct tegra_csi_soc(9)
• struct tegra_csi(9)

all of them, in that order, iykyk 🌈
