See the kern_hyp_va macro and kvm_update_va_mask function for more details. MMIO devices such as -GICv2 gets mapped next to the HYP idmap page. +GICv2 gets mapped next to the HYP idmap page, as do vectors when +ARM64_HARDEN_EL2_VECTORS is selected for particular CPUs. When using KVM with the Virtualization Host Extensions, no additional mappings are created, since the host kernel runs directly in EL2. |
