Subject: [PATCH v4 20/21] KVM: arm64: Export SDEI capability
Date: Sun, 15 Aug 2021 08:13:51 +0800 [thread overview]
Message-ID: <20210815001352.81927-21-gshan@redhat.com> (raw)
In-Reply-To: <20210815001352.81927-1-gshan@redhat.com>
The SDEI functionality is ready to be exported so far. This adds
new capability (KVM_CAP_ARM_SDEI) and exports it.
