🌸 NAME 🌸

okay bestie, meet kvm_riscv_vcpu_mmio_load(9) — we're in the Kernel API Manual 💖 This one is literally about emulating an MMIO load instruction, no cap.

✨ SYNOPSIS ✨

int kvm_riscv_vcpu_mmio_load (struct kvm_vcpu *vcpu , struct kvm_run
       *run , gpa_t fault_addr , unsigned long htinst );

🎀 ARGUMENTS 🎀

• vcpu — the VCPU pointer, aka the vCPU bestie you're working with 🫶
• run — the VCPU run struct containing the mmio data, iconic.
• fault_addr — guest physical address to load 👑
• htinst — transformed encoding of the load instruction, periodt.

💅 DESCRIPTION 💅

Return-code vibe check, because this function is giving choices:

• < 0 — report failure and exit the run-loop 😭
