From cc5e719e2c8086c61bdd9114f42095f8d5b1b0db Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 17 Oct 2023 13:24:33 +0200 Subject: kvm: require KVM_CAP_SIGNAL_MSI This was introduced in KVM in Linux 3.5, we can require it unconditionally in kvm_irqchip_send_msi(). However, not all architectures have to implement it so check it only in x86, the only architecture that ever had MSI injection but not KVM_CAP_SIGNAL_MSI. ARM uses it to detect the presence of the ITS emulation in the kernel, introduced in Linux 4.8. Assume that it's there and possibly fail when realizing the arm-its-kvm device.
