gen6_rps_get_freq_caps(9)

💖 gen6_rps_get_freq_caps(9) 💖

okay bestie, so this is a page straight outta the Kernel API Manual and it's literally about pulling the frequency caps that the hardware itself is exposing. no cap. it's a tiny little function but it's giving "important plumbing" energy, so let's get into it 🫶

---

✨ NAME ✨

gen6_rps_get_freq_caps — Get freq caps exposed by HW 💅

like, the hardware tells you what it can do, and this function is the lil messenger that hands you that info. iconic behavior honestly 🎀

---

🌸 SYNOPSIS 🌸

void gen6_rps_get_freq_caps (struct intel_rps *rps , struct
intel_rps_freq_caps *caps );

she takes two things and returns nothing (void, queen of not needing to prove herself) ✨

---

🦋 ARGUMENTS 🦋

• rps — the intel_rps structure. this is your main character right here 👑 she's the RPS state and she's carrying the whole vibe.
• caps — returned freq caps. yes, "returned" — this is where the caps come back out to you. it's an out-param situation, iykyk 🧚

---

🔥 DESCRIPTION 🔥

So the caps come back to you through caps, and here's the one thing you literally cannot skip, bestie:

Returned "caps" frequencies should be converted to MHz using intel_gpu_freq ⭐

like do NOT just read the raw number and assume it's MHz, okay?? convert first, then celebrate. the frequencies come back raw and intel_gpu_freq is the glow-up that turns them into actual MHz 💖

no extra lore, no secret tricks — that's the whole description, and it ate 🍓
