Subject: [PATCH v2 6/9] docs: kvm: devices/arm-vgic-v3: enhance KVM_DEV_ARM_VGIC_CTRL_INIT doc
Date: Thu, 14 Jan 2021 11:37:05 +0100	[thread overview]
Message-ID: <20210114103708.26763-7-eric.auger@redhat.com> (raw)
In-Reply-To: <20210114103708.26763-1-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.

Signed-off-by: Eric Auger <eric.auger@redhat.com>


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