clk_hw_init_rate_request(9)

💅 clk_hw_init_rate_request(9) — from the Kernel API Manual, bestie

okay so this is a page about one tiny function that sets up your rate request before you go ask the clock core for a favour. it's a void function, meaning it does the thing and gives you nothing back — and honestly? iconic behaviour. no return value, no drama, just vibes and a correctly-initialised struct. 🎀

✨ NAME ✨

clk_hw_init_rate_request — Initializes a clk_rate_request

like literally that's it, that's the whole job. it takes your empty little struct and fills it in so you can go submit it. 🦋

🌸 SYNOPSIS 🌸

void clk_hw_init_rate_request (const struct clk_hw *hw , struct
       clk_rate_request *req , unsigned long rate );

three things go in, nothing comes out. void main character energy fr fr. 💫

🎀 ARGUMENTS 🎀

  • hw — the clk you're repping, aka the one you wanna submit a rate request for 👑
  • req — the clk_rate_request structure you want to initialise. this is the glow-up target, she's about to get all her fields filled in 💅
  • rate — the rate you're requesting. the number. the goal. the dream. ⭐

💖 DESCRIPTION 💖

so what it does: Initializes a clk_rate_request structure to submit to __clk_determine_rate or similar functions.

that's the whole flex, bestie — it's the setup step, not the main event. you prep the clk_rate_request here, then hand it off to __clk_determine_rate or whatever similar function is on duty that day. think of it as doing your hair before the party: the party is __clk_determine_rate, and this function is you with the curling iron. ✨🫶

ngl it's a small function but it's load-bearing, so don't skip it. 🙈

🦋 SEE ALSO 🦋

first up, the source, so you can go read the real thing: Kernel file ./drivers/clk/clk.c

and now the full link-up, no cap, every single one:

like… that's the whole clock family reunion right there. every cousin showed up. 💀🔥

seriously though bestie, that's a lot of neighbours — if you're poking at rate stuff, at least skim __clk_determine_rate(9) and clk_hw_forward_rate_request(9) so you know where your freshly-initialised struct is actually headed. 🫶

and that's the page!! mwah 💋 this one lives under ./drivers/clk and it's dated October 2026 — so go forth, init your clk_rate_request, and slay. 👑🌸✨
