💥 kvm_inject_dabt_excl_atomic(9) 💥

okay so this is a page from the Kernel API Manual, and honestly? It's giving "tiny but important" energy. We're talking about kvm_inject_dabt_excl_atomic, bestie — the function that injects a data abort when a guest tries an unsupported exclusive or atomic access. 💅

✨ NAME ✨

kvm_inject_dabt_excl_atomic — inject a data abort for unsupported exclusive or atomic access

🎀 SYNOPSIS 🎀

int kvm_inject_dabt_excl_atomic (struct kvm_vcpu *vcpu , u64 addr );

🫶 ARGUMENTS 🫶

• vcpu — the VCPU that's gonna receive the data abort. like, that's the whole point, bestie. 💖
• addr — the address to report in the DFAR. yes, exactly that address. no cap. 📍

🌸 DESCRIPTION 🌸

Bestie, there's an assumption here and we gotta respect it: this code is assumed to be called from the VCPU thread, and because of that, the VCPU is therefore not currently executing guest code. periodt. 💀✨
