Subject: [PATCH kvmtool v3 04/17] arm: Stash kvm_vcpu_init for later use
Date: Wed, 2 Aug 2023 23:42:42 +0000 [thread overview]
Message-ID: <20230802234255.466782-5-oliver.upton@linux.dev> (raw)
In-Reply-To: <20230802234255.466782-1-oliver.upton@linux.dev>
A subsequent change will add support for resetting a vCPU, which
requires reissuing the KVM_ARM_VCPU_INIT ioctl. Save the kvm_vcpu_init
worked out for later use.
