Subject: [PATCH v3 5/8] docs: kvm: devices/arm-vgic-v3: enhance KVM_DEV_ARM_VGIC_CTRL_INIT doc
Date: Fri, 12 Mar 2021 18:31:59 +0100 [thread overview]
Message-ID: <20210312173202.89576-6-eric.auger@redhat.com> (raw)
In-Reply-To: <20210312173202.89576-1-eric.auger@redhat.com>
kvm_arch_vcpu_precreate() returns -EBUSY if the vgic is
already initialized. So let's document that KVM_DEV_ARM_VGIC_CTRL_INIT
must be called after all vcpu creations.

v1 -> v2:
- Must be called after all vcpu creations ->
Must be called after all VCPUs have been created as per
Alexandru's suggestion
