Subject: [PATCH v5 15/17] ARM64: XEN: Add a function to initialize Xen specific UEFI runtime services
Date: Fri, 4 Mar 2016 14:37:33 +0800 [thread overview]
Message-ID: <1457073455-11516-16-git-send-email-zhaoshenglong__21411.761819809$1457073687$gmane$org@huawei.com> (raw)
In-Reply-To: <1457073455-11516-1-git-send-email-zhaoshenglong@huawei.com>
From: Shannon Zhao <shannon.zhao@linaro.org>
When running on Xen hypervisor, runtime services are supported through
hypercall. Add a Xen specific function to initialize runtime services.
