💅 ice_ptp_write_perout(9)

okay so bestie, welcome to the Kernel API Manual ✨ this one's a function page, it lives in section 9 (that's the kernel-API girlies), and it's all about pushing your periodic wave settings down into the actual hardware. no cap, that's the whole vibe.

🌸 NAME 🌸

ice_ptp_write_perout — literally just Write periodic wave parameters to HW 🫶

✨ SYNOPSIS ✨

int ice_ptp_write_perout (struct ice_hw *hw , unsigned int chan ,
       unsigned int gpio_pin , u64 start , u64 period );

like, look at her. five args, returns an int, iconic. 👑

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW struct 💜 that's your hardware, your main character.
  • chan — target channel 🦋 yes, which channel. you gotta pick one.
  • gpio_pin — target GPIO pin 📍 the actual pin that's getting this wave.
  • start — target time to start periodic output ⏰ when the wave kicks off.
  • period — target period 🌈 the length of one full cycle.

⭐ RETURN ⭐

0 on success, negative error code otherwise 💀 so fr fr, check that return value. zero means slay, anything negative means something went sideways.

the whole friend group, honestly. like, this page is not doing it alone:

and that's the page!! 🍓 this cutie came out of ./drivers/net/ethernet/intel/ice and it's dated October 2026 — go off, intel ice driver, we love a timestamps-and-periodic-output moment. mwah 💋✨
