From 127770ac0d043435375ab86434f31a93efa88215 Mon Sep 17 00:00:00 2001 From: Aaron Lewis Date: Mon, 14 Feb 2022 21:29:51 +0000 Subject: KVM: x86: Add KVM_CAP_ENABLE_CAP to x86 Follow the precedent set by other architectures that support the VCPU ioctl, KVM_ENABLE_CAP, and advertise the VM extension, KVM_CAP_ENABLE_CAP. This way, userspace can ensure that KVM_ENABLE_CAP is available on a vcpu before using it.
