cpc_supported_by_cpu(9)

💖 NAME 💖

okay so this is the Kernel API Manual page for cpc_supported_by_cpu(9), and it's literally here to check if CPPC is supported by CPU ✨. That's the name, bestie — no cap.

✨ SYNOPSIS ✨

bool cpc_supported_by_cpu (void );

🎀 ARGUMENTS 🎀

• void — no arguments. Zero. Zilch. The function said “I need nothing from you” and honestly, main character energy 🫶.

🦋 DESCRIPTION 🦋

It checks if the architectural support for CPPC is present even if the _OSC hasn't prescribed it. That's the whole tea ☕ — lowkey a support check, highkey useful.

🌸 RETURN 🌸

• true — supported 💖
• false — not supported 🙈
