ixgbe_i2c_bus_clear(9)
πΈ NAME πΈ
ixgbe_i2c_bus_clear β clears the I2C bus, bestie. This is the ixgbe_i2c_bus_clear(9) page from the Kernel API Manual, and we're gonna get you comfy with it.
β¨ SYNOPSIS β¨
void ixgbe_i2c_bus_clear (struct ixgbe_hw *hw );
π ARGUMENTS π
hwβ pointer to hardware structure. That's the whole vibe, no cap.
π¦ DESCRIPTION π¦
okay so here's the tea: this function clears the I2C bus by sending nine clock pulses. Nine. Not eight, not ten β nine, periodt. It's the move for when the data line is stuck low. You know that mood? The line's just sitting there, lowkey refusing to move, and ixgbe_i2c_bus_clear comes in with the clock pulses like "girl, get up." π
That's the stated use case: data line stuck low. Don't invent extra drama about what else it fixes β the page says what it says.
