Subject: Install qemu and create agl-egvirt machine feature
X-Git-Tag: 4.99.1~3
X-Git-Url: https://gerrit.automotivelinux.org/gerrit/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F47%2F10547%2F2;p=AGL%2Fmeta-agl-devel.git

Install qemu and create agl-egvirt machine feature

qemu is the userspace emulator needed to run KVM virtual machines.
This patch adds a bbappend for qemu in the meta-egvirt layer, and
includes it in the packages to be installed in the AGL distro.
To do this, the new agl-egvirt machine feature has been created
and is used to enable virtualization specific extensions
created by the EG-VIRT group for AGL.

In order to reduce its impact on the AGL image, the qemu targets
have been limited to aarch64 and x86_64 only.

Changelog v2:
- agl-egvirt added to MACHINE_FEATURES
- use of class_target to not create conflict by the QEMU version
  used in the SDK and the one used by KVM
- README file updated accordingly

Bug-AGL: SPEC-718

+How to enable agl virtualization feature
+------------------------------------------------------
+In order to enable the agl virtualization features (agl-egvirt),
+each supported board needs to add in one of its configuration
+files (see for instance meta-agl/meta-agl-bsp/conf/include)
+the following line:
+
+MACHINE_FEATURES += "agl-egvirt"
