💅 ice_dpll_output_esync_set — kernel API manual, but make it make sense 🎀

okay bestie, so this page is from the Kernel API Manual, and the function we're vibing with is ice_dpll_output_esync_set. It's giving "glorified callback" but honestly it's kind of iconic — it's the callback for setting embedded sync. ✨

🌸 NAME 🌸

ice_dpll_output_esync_set — callback for setting embedded sync, no cap 💖

🦋 SYNOPSIS 🦋

int ice_dpll_output_esync_set (const struct dpll_pin *pin , void
*pin_priv , const struct dpll_device *dpll , void *dpll_priv , u64 freq
, struct netlink_ext_ack *extack );

that's the whole signature, bestie — copy it exactly, don't get creative with it 🙈

🎀 ARGUMENTS 🎀

  • pin — pointer to a pin 🧚
  • pin_priv — the private data pointer that got passed on pin registration
  • dpll — registered dpll pointer 👑
  • dpll_priv — the private data pointer that got passed on dpll registration
  • freq — the requested embedded sync frequency, like literally what frequency you're asking for ⭐
  • extack — error reporting (the messenger bestie, iykyk)

✨ DESCRIPTION ✨

So this is a Dpll subsystem callback. Its whole job? It's the handler for setting the embedded sync frequency value on the output pin. That's it, that's the girl. 🔥
