ice_tspll_cfg_e825c(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to ice_tspll_cfg_e825c(9) from the Kernel API Manual — we're configuring the TSPLL for E825-C and honestly it's giving main-character clock energy. 💅✨

💖 NAME 💖

ice_tspll_cfg_e825c — Configure the TSPLL for E825-C. 🎀

✨ SYNOPSIS ✨

int ice_tspll_cfg_e825c (struct ice_hw *hw , enum ice_tspll_freq
       clk_freq , enum ice_clk_src clk_src );

🎀 ARGUMENTS 🎀

  • hw — Pointer to the HW struct. 🫶
  • clk_freq — Clock frequency to program. ⏰
  • clk_src — Clock source to select (TIME_REF, or TCXO). 🌸

🦋 DESCRIPTION 🦋

Okay so here's the actual glow-up: this configures the Clock Generation Unit with the desired clock frequency and time reference, enabling the PLL which drives the PTP hardware clock. ✨ No cap, that's the whole vibe.

💅 RETURN 💅

  • 0 — success 🎉
  • -EINVAL — input parameters are incorrect 🙈
  • -EBUSY — failed to lock TSPLL 💀
  • other — CGU read/write failure 😭
