✨ sifive_prci_..._use_corepll(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 — yes the page header says sifive_prci_..._use_corepll(9) and the actual function is sifive_prci_corepllsel_use_corepll, that's just how the title got truncated, no cap, we move.

🎀 NAME 🎀

sifive_prci_corepllsel_use_corepll — switch the COREPLL mux to output COREPLL 💅

🌸 SYNOPSIS 🌸

void sifive_prci_corepllsel_use_corepll (struct __prci_data *pd );

🦋 ARGUMENTS 🦋

  • pd — a struct __prci_data * for the PRCI that's holding the COREPLL mux reg. that's it, that's the whole argument list, she's lowkey minimalist 🫶

⭐ DESCRIPTION ⭐

So what does she actually do? She switches the COREPLL mux over to the COREPLL output clock, and then returns once that's done. like, done done. ✨ no lingering, no "just one more thing", she completes the switch and bounces.

💜 CONTEXT 💜

Any context. literally any. 🌈

but bestie, listen — the caller must prevent concurrent changes to the PRCI_COREPLLSEL_OFFSET register. that part is on you, not on her. protect that register like it's your iced coffee in a heatwave 🧊😭

🔥 SEE ALSO 🔥

Kernel file ./drivers/clk/sifive/sifive-prci.c — go read it, iykyk 👑

that's the whole clique, they all ate 💅

anyway bestie that's the page 🎀 it lives under ./drivers/clk/sifive, the version vibes are October 2026, and the manual is the Kernel API Manual for sifive_prci_..._use_corepll(9) — go switch that mux, love u, bye! 👋💖✨
