🦋 pch_i2c_xfer — from the Kernel API Manual, bestie 💅

Ok so real talk, this is a page straight out of the Kernel API Manual, and it's literally about moving bytes around on an I2C bus. Reading, writing, the whole vibe. Let's get into it ✨

🌸 NAME 🌸

pch_i2c_xfer — reading and writing data through the I2C bus. That's it, that's the whole job. She transfers, she slays, she goes home. 👑

✨ SYNOPSIS ✨

s32 pch_i2c_xfer (struct i2c_adapter *i2c_adap , struct i2c_msg *msgs ,
s32 num );

Like, this is the whole signature. Three args, one s32 coming back at you. Copy it exactly, no cap. 🫶

🎀 ARGUMENTS 🎀

  • i2c_adap — a pointer to the struct i2c_adapter. That's your adapter, your whole little I2C world. 🌍
  • msgs — a pointer to the i2c_msg structure. Your messages live here. 💌
  • num — the number of messages. Yes bestie, you have to say how many. 🔢

Alright, this is the part where I introduce you to the whole friend group. The kernel file they all hang out in is ./drivers/i2c/busses/i2c-eg20t.c — go say hi. 🏠

Like, the entire cast. Go read them all, iykyk. 📚✨

ok that's the whole page and honestly? she ate. no crumbs. 🍓

Bye bestie, this one came from ./drivers/i2c/busses, dated October 2026 — and that's pch_i2c_xfer(9), signing off 💖🧚‍♀️🌈
