[PATCH v2 1/8] hvf: Add hypervisor entitlement to output binaries


From: Alexander Graf
Subject: [PATCH v2 1/8] hvf: Add hypervisor entitlement to output binaries
Date: Mon, 30 Nov 2020 04:07:16 +0100

In macOS 11, QEMU only gets access to Hypervisor.framework if it has the
respective entitlement. Add an entitlement template and automatically self
sign and apply the entitlement in the build.
