This is a small example virtual machine monitor, that uses the base-hw kernel
|
|
as TrustZone micro-hypervisor on the ARM Versatile Express CT A9x4 platform.
|
|
The VMM configures TrustZone Protection Controller and Address Space Controller
|
|
in a way, that allows a guest to access nearly all devices, and the DDR-RAM.
|
|
Only few resources needed by the kernel (timer, SRAM) aren't accessable by the
|
|
virtual-machine.
|
|
|
|
Moreover, the VMM prepares the guest memory with a Linux image, and ramdisk,
|
|
and boots it. For the Linux guest to work properly a small patch, and tweaked
|
|
configuration is needed. Please checkout the following branch to test it:
