💖 smu_v14_0_0_find_clk_level(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for smu_v14_0_0_find_clk_level(9) — yes that's the whole name, yes it's a mouthful, no we are not abbreviating it, it's iconic as-is 🎀

---

✨ NAME ✨

smu_v14_0_0_find_clk_level — finds the closest DPM level for a given frequency, no cap 💅

---

🦋 SYNOPSIS 🦋

uint8_t smu_v14_0_0_find_clk_level (const uint32_t *freqs , uint8_t
count , uint32_t target );

like literally that's the whole signature, she's compact and she knows it ✨

---

🌸 ARGUMENTS 🌸

• freqs — an array of frequencies, one per DPM level. think of it as the roster of every level's clock speed 📋
• count — how many entries in freqs are actually valid (the rest are not giving anything, so don't count them) 🔢
• target — the frequency you're trying to match. this is the main character of the whole function, periodt 👑

---

💜 DESCRIPTION 💜

So here's the tea 🍓: this function returns the index</> of the DPM level whose frequency is closest to target.

If an exact match exists — like, an actual perfect match — that one is preferred. slay. otherwise it falls back to the nearest level by absolute difference, which is lowkey just "whoever's closest wins" 💀

ngl it's giving "close enough is good enough" but in a mathematically rigorous way, and honestly? we respect it 🫶
