X86_MATCH_VENDOR_FAM(9)

📦 version 7.3.1, in nixpkgs unstable

✨ X86_MATCH_VENDOR_FAM ✨

okay so bestie, welcome to the X86_MATCH_VENDOR_FAM(9) page from the Kernel API Manual 💅 this one is short and sweet and honestly iconic — it's literally the macro that matches a CPU by vendor and family, and it eats every single time 🍓

🌸 NAME 🌸

X86_MATCH_VENDOR_FAM — match vendor and family, no cap 🫶

🎀 SYNOPSIS 🎀

X86_MATCH_VENDOR_FAM (vendor , family , data );

like yes, that's the whole vibe check right there ✨ three args, zero drama.

💖 ARGUMENTS 💖

  • vendor — the vendor name, bestie! things like INTEL, AMD, HYGON, ..., and ANY 🦋 and here's the cute part: the name gets expanded to X86_VENDOR_vendor 🔥 so it's giving "you write the short version, the macro does the glow-up."
  • family — the family number, or X86_FAMILY_ANY if you're in your "idc, any family works" era 💀
  • data — driver-specific data, or NULL if you've got nothing to say 🙈 the internal storage format is unsigned long, and whatever you supply — value, pointer, etc. — gets casted to unsigned long internally ⭐ so just know it's all getting squished into an unsigned long on the inside, iykyk.
