ixgbe_i2c_start(9)

💅 ixgbe_i2c_start(9) — the I2C start-condition page, but make it cute 💅

okay so bestie, welcome to the ixgbe_i2c_start(9) page in the Kernel API Manual — yes, that Kernel API Manual, and yes, we're about to make an I2C start condition sound iconic. no cap. 🫶

🌸 NAME 🌸

ixgbe_i2c_start — sets I2C start condition. That's the whole name, and honestly it ate.

✨ SYNOPSIS ✨

void ixgbe_i2c_start (struct ixgbe_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. one pointer, one job, main-character energy. 💅

🦋 DESCRIPTION 🦋

okay so what does this function actually do? It sets the I2C start condition — literally High -> Low on SDA while SCL is High — and it sets bit-bang mode on X550 hardware. That's the vibe. 🫶
