sci_clk_recalc_rate(9)

💅 sci_clk_recalc_rate (Kernel API Manual energy)

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is sci_clk_recalc_rate(9), and honestly? she's a tiny little function with one job and she does it. no cap.

---

🎀 NAME 🎀

sci_clk_recalc_rate — get the clock rate for a TI SCI clock 🌸

like. that's it. that's the whole vibe. she recalculates the rate. iconic behavior.

---

✨ SYNOPSIS ✨

unsigned long sci_clk_recalc_rate (struct clk_hw *hw , unsigned long
       parent_rate );

yup, she takes two things, she returns an unsigned long. simple. elegant. ate. 🫶

---

🦋 ARGUMENTS 🦋

• hw — the clock you wanna get the rate for 👑 this is the one that actually matters
• parent_rate — the parent rate, handed to you by the common clock framework, and ngl… it is literally not used 🙈 the framework is just being polite

---

💖 DESCRIPTION 💖

so what she does is: she gets the current clock rate of a TI SCI clock. that's the whole bit. 💅

she returns the current clock rate 🌟 — or zero if it fails 😭 (yes, zero is the "something went wrong" number here, so if you see a 0 coming out of this, do a little vibe check on your error handling, fr fr).
