💖 ISMT(4) 💖

okay so real talk, this is the ismt page from the Kernel Interfaces Manual and it's short but it's mighty, bestie. buckle up, it's like four sections and every single one of them ate 🎀

✨ NAME ✨

ismt — the Intel SMBus Message Transport (SMBus 2.0) driver, no cap 💅

🌸 SYNOPSIS 🌸

the way you summon this thing is literally just these four lines in your kernel config, in this exact order, don't be weird about it:

device pci
device smbus
device smb
device ismt

like yes you need pci first because it's an interface child, and yes you need smbus and smb because they're different things and the driver needs both, iykyk 🦋

💫 DESCRIPTION 💫

so this driver gives you access to the SMBus 2.0 controller device that lives inside the Intel Atom S1200, C2000 and C3000 CPUs. that's it. that's the whole vibe. it's the little bridge between your kernel and the smbus controller that's baked right into those Atom chips 🫶

highkey iconic that it just. lives in the CPU. main character energy fr 🔥
