vgic_target_oracle(9)

💅 vgic_target_oracle(9) — Kernel API Manual ✨

okay bestie, welcome to the vgic_target_oracle(9) page in the Kernel API Manual. it's giving kernel-internals realness, and we're keeping every detail. 🫶

🌸 NAME 🌸

vgic_target_oracle — compute the target vcpu for an irq. no cap. 🎯

✨ SYNOPSIS ✨

struct kvm_vcpu * vgic_target_oracle (struct vgic_irq *irq );

🎀 ARGUMENTS 🎀

• irq — the irq to route. bestie, it must be already locked. 🔒

🦋 DESCRIPTION 🦋

okay so: based on the current state of the interrupt (enabled, pending, active, vcpu and target_vcpu), this function computes the next vcpu this should be given to. literally the matchmaker for interrupts. 💖

it returns NULL if this shouldn't be injected at all. not every irq gets a rose on this season, and that's valid. 🌹

🚨 requires the IRQ lock to be held. like, do not skip this. the lock is the vibe check. 🔒
