💅 ixgbe_lower_i2c_clk(9)

okay so bestie, welcome to the Kernel API Manual entry for ixgbe_lower_i2c_clk — yes that's the whole manual name, no cap, it's a kernel API manual and we're gonna read it together 🫶

✨ NAME ✨

ixgbe_lower_i2c_clk — lowers the I2C SCL clock. that's it. that's the whole gig. literally one job and she does it 💅

🌸 SYNOPSIS 🌸

void ixgbe_lower_i2c_clk (struct ixgbe_hw *hw , u32 *i2cctl );

returns nothing (void, queen of not giving anything back) and takes two args. periodt.

🎀 ARGUMENTS 🎀

  • hw — pointer to hardware structure. like, the actual hardware vibe check, you pass her the whole struct and she knows what to do ✨
  • i2cctl — the current value of the I2CCTL register. you hand her the register value, she's gonna do something with it (it's a u32 *, so it's a pointer, iykyk) 🔥

🦋 DESCRIPTION 🦋

so what does she do. okay. she lowers the I2C clock line, going '1'->'0'. that's the entire move. SCL goes from high to low, iconic 🌈

also — and this is the part people forget — on X550 hardware she asserts the I2C clock output enable. so if you're on X550, that's happening too. not me forgetting that detail, because I would never 🙈
