💖 intel_guc_slpc_set_min_freq(9) 💖

okay so bestie, we're in the Kernel API Manual and this one is specifically the intel_guc_slpc_set_min_freq(9) page — yes, the whole page is named after the function, main character energy fr fr. Let's get into it ✨

---

🌸 NAME 🌸

intel_guc_slpc_set_min_freq — literally just here to Set min frequency limit for SLPC. That's the whole vibe. 💅

---

🎀 SYNOPSIS 🎀

int intel_guc_slpc_set_min_freq (struct intel_guc_slpc *slpc , u32 val
);

That's the signature, copy it exactly, don't @ me 🫶

---

🦋 ARGUMENTS 🦋

• slpc — pointer to intel_guc_slpc. yeah. a pointer. to one of those. 😌
• val — frequency (MHz). that's it, that's the number, in megahertz 🍓

---

✨ DESCRIPTION ✨

So what does it do? This function will invoke GuC SLPC action to update the min unslice frequency. That's the entire description, no cap — it goes and pokes the GuC SLPC so the min unslice frequency gets updated. iconic behavior honestly 🌈

---

⭐ RETURN ⭐

• 0 on success 🎉
• non-zero error code on failure 😭 (so like, check it. always check it. bestie please.)

💜 SEE ALSO 💜

• Kernel file ./drivers/gpu/drm/i915/gt/uc/intel_guc_slpc.c — that's where the source lives, go read it if you're nosy (i love that for you) 💖

• intel_guc_slpc_set_max_freq(9)
• intel_guc_slpc_get_max_freq(9)

like, the whole min/max family, they're all linked, it's giving found family 🧚

lowkey reminder: this page lives under the ./drivers/gpu/drm/i915/gt/uc path and the manual is dated October 2026, so if you're reading this from the future... hi 👑 also everything above is verbatim from the page, i did not make a single thing up 💅

okay that's the whole page, mwah, go set that min frequency bestie 💖✨🎀
