From: Jonathan Cameron <jonathan.came...@huawei.com> Only add one very simple example as all the i386/pc examples will work for arm/virt with a change to appropriate executable and appropriate standard launch line for arm/virt. Note that max cpu is used to ensure we have plenty of physical address space.
