X86_MATCH_VFM_FEATURE(9)

🌸 NAME 🌸

okay bestie, welcome to the Kernel API Manual page for X86_MATCH_VFM_FEATURE(9) — this macro is here to match the encoded vendor/family/model/feature combo, and it’s lowkey giving CPU-detection main character energy 💅✨

✨ SYNOPSIS ✨

X86_MATCH_VFM_FEATURE (vfm , feature , data );

🎀 ARGUMENTS 🎀

• vfm — the encoded combo: 8-bits each for vendor, family, and model 🫶
• feature — a X86_FEATURE bit ⭐
• data — driver specific data or NULL. The internal storage format is unsigned long. The supplied value, pointer etc. is cast to unsigned long internally 😭

ngl, that unsigned long internal-storage detail is the whole vibe check for this argument — don’t forget it 🧚
