STRUCT NOUVEAU_I2C_ENCODER(9)

💖 STRUCT NOUVEAU_I2C_ENCODER(9) 💖

okay bestie, buckle up, because this is a page from the Kernel API Manual — yes, the <pink>struct nouveau_i2c_encoder(9)</pink> one specifically — and it's actually kind of a slay once you get past the C syntax 💅

---

✨ NAME ✨

struct nouveau_i2c_encoder — the I2C encoder struct, and yes she's exactly what she sounds like 🎀

---

🌸 SYNOPSIS 🌸

bestie, here's the whole vibe, copy-pasted exactly because I would NEVER mess with your struct:

struct nouveau_i2c_encoder {
    struct drm_encoder base;
    const struct nouveau_i2c_encoder_funcs *encoder_i2c_funcs;
    void *encoder_i2c_priv;
    struct i2c_client *i2c_client;
 };

look at her. four members. iconic. 😌

---

🦋 Members 🦋

• base — the DRM encoder object, like the main character she literally is 👑
• encoder_i2c_funcs — the I2C encoder callbacks. her little entourage of function pointers ✨
• encoder_i2c_priv — the I2C encoder private data. lowkey her diary, nobody else's business 🙈
• i2c_client — the corresponding I2C client structure. her plus-one 🫶

---

💜 Description 💜

so here's the tea, and it's genuinely interesting ngl ☕

A nouveau_i2c_encoder lowkey has two sets of callbacks: encoder_i2c_funcs and the ones chilling inside base. and here's the thing bestie — the ones in encoder_i2c_funcs are never actually called by the common CRTC code 😭 not once. they're not there to be called, they're just a convenience thing 💅

the whole point is splitting the encoder functions into two layers:

• an upper, GPU-specific layer 🔥
• and a (hopefully) GPU-agnostic lower layer 🌈

and because nothing in life is free, it's the GPU driver's responsibility to call the nouveau_i2c_encoder methods when appropriate. so like, nobody's gonna do it for you, bestie. that's your job now 🫡

also, nouveau_i2c_encoder_init provides a way to get an implementation of this whole thing. that's your entry point, iykyk ⭐

🎀 SEE ALSO 🎀

go look at these, fr fr:

• the kernel file ./drivers/gpu/drm/nouveau/include/dispnv04/i2c/encoder_i2c.h

ngl the source attribution got cut off in the footer — all that survives is ./drivers/gpu/drm/nouveau/incl... — but it's dated October 2026 and it's from the struct nouveau_i2c_encoder(9) page in the Kernel API Manual, so jot that down bestie 📝

and that's the whole page, periodt 💅✨ tysm for reading, go forth and call your encoder methods responsibly, mwah 🫶💖
