📦 version 7.3.1, in nixpkgs unstable

💅 clk_hw_round_rate(9) 💅

okay so bestie, welcome to the Kernel API Manual page for clk_hw_round_rate(9) — yes it's a real function, yes it's lowkey the moment your rate gets ✨glowed up✨ so the hardware can actually deal with it. let's get into it 🎀

🌸 NAME 🌸

clk_hw_round_rate — round the given rate for a hw clk ✨

🦋 SYNOPSIS 🦋

unsigned long clk_hw_round_rate (struct clk_hw *hw , unsigned long rate
);

💖 ARGUMENTS 💖

  • hw — the hw clk for which we are rounding a rate. this is the main character here 👑
  • rate — the rate which is to be rounded. she's giving raw input energy, about to get a makeover 💅

🌈 DESCRIPTION 🌈

So here's the vibe: you hand her a rate as input, and she rounds it to a rate that the clk can actually use. no cap, it's that simple — takes your number, gives it the vibe check, returns one that fits the hardware's whole situation 🫶

⭐ CONTEXT ⭐

🚨 important bestie 🚨 prepare_lock must be held. fr fr, don't skip this one.

This is for clk providers to call from within clk_ops, like .determine_rate — iykyk 💜

🔥 RETURN 🔥

  • returns the rounded rate of the hw clk if the clk supports the determine_rate operation ✨
  • else, it returns the parent rate 💀 (still valid, just not the glow-up you asked for)

🎀 SEE ALSO 🎀

okay this list is long long — but every single one is here, no skips, periodt 💅
