💅 dfll_scale_dvco_rate(9) ✨

okay so this is a Kernel API Manual page, and it's literally about turning a DVCO rate into a scaled rate. bestie, it's short, it's sweet, it's giving "small function, big responsibilities" energy 🎀

🌸 SYNOPSIS 🌸

unsigned long dfll_scale_dvco_rate (int scale_bits , unsigned long
       dvco_rate );

like, yes, that's the whole signature. she's not complicated 💅

🦋 ARGUMENTS 🦋

  • scale_bits — the clock scaler value, aka the bits chillin' in the DFLL_FREQ_REQ_SCALE field. that's her whole personality 🫶
  • dvco_rate — the DVCO rate itself. the raw material. the moment before the glow-up ✨

💖 DESCRIPTION 💖

so what does it actually do? it applies the same scaling formula that the DFLL hardware uses to scale the DVCO rate. that's it. that's the whole thing. no cap 💀

it's giving "software matching hardware, frame for frame" — you're not inventing a new math, you're just doing the exact same math the silicon does, so the numbers agree. iconic behavior honestly 👑

⭐ SEE ALSO ⭐

the whole fam, and yes we're listing every single one because nobody gets left out 💜

Kernel file ./drivers/clk/tegra/clk-dfll.c

ngl if you're reading all 40 of those, you're a real one. drink some water 🍓

and that's the page!! this lives over in ./drivers/clk/tegra, dated October 2026, and it's page dfll_scale_dvco_rate(9) — mwah, go forth and scale those rates bestie 💅🌈✨
