clk_determine_rate_noop(9)

✨ clk_determine_rate_noop(9) ✨

okay so bestie, this page is from the Kernel API Manual, and it’s all about the noop determine_rate hook. lowkey iconic, highkey useful. 🎀

🌸 NAME 🌸

clk_determine_rate_noop — the noop implementation of clk_ops::determine_rate. it’s giving “I don’t need to do anything, the rate is already handled.” 💅

✨ SYNOPSIS ✨

here’s the exact signature, no edits, no cap:

int clk_determine_rate_noop (struct clk_hw *hw , struct clk_rate_request
       *req );

💅 ARGUMENTS 💅

• hw — the clk you’re determining the rate on.
• req — the rate request.

🦋 DESCRIPTION 🦋

This is the noop determine-rate situation for clocks where the rate rounding is handled by the firmware/hardware, or where the clock is capable of any rate. The requested rate is passed through unchanged, and the actual rate will be learned via recalc_rate after the rate is set. so it’s not doing the math — it’s just letting the request through and trusting recalc_rate to spill the tea later. 🫶

🌸 RETURN 🌸

0 always. every single time. periodt. 💖
