ADD-IN MANAGEMENT CONTROLLER (AMC)(9)

💅 Add-In Management Controller (AMC) 💅

okay so this one lives in the Kernel API Manual, section 9 (kernel API, bestie — we're deep in the kernel here 🧚), and the page header calls it, and I quote, Add-In Manag...roller (AMC). Yes the header got chopped mid-word, she's a little truncated, it happens to the best of us 💀. The full name is Add-In Management Controller, aka AMC. Slay.

✨ NAME ✨

Add-In Management Controller (AMC) — the handler for the SMBus Alerts coming off the AMC. 🦋

🌸 DESCRIPTION 🌸

okay so picture this: the AMC is out here sending SMBus Alerts, and this thing? this little icon 👑 right here is the handler for them. that's literally her whole job. she catches the alerts. that's the gig. no cap 🫶

and here's the part you actually need to know, bestie, so listen up 🔥 — all the alerts from AMC will cause the device to be declared wedged.

all of them. every single one. it's giving zero tolerance, it's giving no chill whatsoever 😭. one alert comes in and the device is officially wedged, periodt. that's the behaviour, that's canon, don't @ me 💅

literally not me warning you: this is the documented behaviour fr fr — an AMC alert = the device gets declared wedged. plan accordingly, bestie 🙈
