cpuid_leaf_raw(9)

🌸 NAME 🌸

cpuid_leaf_raw — Access parsed CPUID data in raw format. Okay bestie, this is from the Kernel API Manual, and it's giving raw-data realness for CPUID 👑✨

🎀 SYNOPSIS 🎀

cpuid_leaf_raw (_cpuinfo , _leaf );

💅 ARGUMENTS 💅

• _cpuinfo — the CPU capability structure reference ('struct cpuinfo_x86') 🫶
• _leaf — the CPUID leaf, in compile-time 0xN format. Yes, literally compile-time 0xN, iykyk 🧚

✨ DESCRIPTION ✨

So it's similar to cpuid_leaf, but here's the plot twist: it returns a raw struct cpuid_regs pointer to the parsed CPUID data instead of a “typed” <asm/cpuid/leaf_types.h> pointer. That's the whole flex — raw format, no typed wrapper, periodt 💅🔥
