From 2cb81af0b1add4fa4f3582a913e0f8aaf1e77eb8 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 17 Oct 2023 13:47:21 +0200 Subject: [PATCH] kvm: unify listeners for PIO address space Since we now assume that ioeventfds are present, kvm_io_listener is always registered. Merge it with kvm_coalesced_pio_listener in a single listener. Since PIO space does not have KVM memslots attached to it, the priority is irrelevant.
