💅 ice_write_cgu_reg(9) 💅

okay so this is the Kernel API Manual page for ice_write_cgu_reg, and we're about to make CGU register-writing make sense, bestie. 💖

🌸 NAME 🌸

ice_write_cgu_reg — write a CGU register. That's the whole errand, no cap. ✨

🦋 SYNOPSIS 🦋

here's the exact signature, character for character:

int ice_write_cgu_reg (struct ice_hw *hw , u32 addr , u32 val );

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW struct, aka the hardware context.
  • addr — register address to write.
  • val — value to write into the register.

✨ DESCRIPTION ✨

Write the specified value to a register of the Clock Generation Unit. Only applicable to E82X devices, so if you're not on E82X this is not your era, bestie. 💅

🌈 RETURN 🌈

0 on success, other error codes when failed to write to CGU. A 0 is the slay; anything else means the CGU write did not go through. 😭

👑 SEE ALSO 👑

Kernel file ./drivers/net/ethernet/intel/ice/ice_common.c is the home base, and the whole function squad is right here — no gatekeeping:

before you go, the source/version footer energy is ./drivers/net/ethernet/intel/ice, the date is October 2026, and this page is literally ice_write_cgu_reg(9). bye bestie, go write that CGU register with main character energy 💖✨
