kvm_vgic_early_init(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ kvm_vgic_early_init ✨

okay so bestie, welcome to the Kernel API Manual β€” this is the page for kvm_vgic_early_init(9), and honestly? it's giving "tiny function, big responsibilities" energy πŸ’…


🌸 NAME 🌸

kvm_vgic_early_init β€” Initialize static VGIC VCPU data structures

like, it sets up the static stuff. the foundational vibes. the scaffolding πŸŽ€


πŸ’– SYNOPSIS πŸ’–

void kvm_vgic_early_init (struct kvm *kvm );

no return value, just vibes and one argument, slay ✨


πŸ¦‹ ARGUMENTS πŸ¦‹

  • kvm β€” The VM whose VGIC districutor should be initialized πŸ‘‘

(yes, the manpage literally spells it "districutor" β€” that's not me being chaotic, that's canon, iykyk 😭)


🌈 DESCRIPTION 🌈

okay so the whole entire point here: this function only does initialization of static structures β€” the ones that don't require any allocation, and don't need any sizing information from userspace. none. zero. not a single byte of user input required, no cap πŸ™…β€β™€οΈ

the rest of the work? that's handled elsewhere. specifically, vgic_init calls kvm_vgic_dist_init, and that one takes care of the rest πŸ’… so don't come for this function asking why it didn't do everything β€” it was never the main character of that particular plotline, it's the opening act πŸ‘‘
