It is built for embedded IOT with small footprint and real-time features. More details can be found in https://projectacrn.org/ This is the patch set that add the ACRN driver module on ACRN guest, which acts as the router to communciate with ACRN hypervisor. The user-space applications can use the provided ACRN ioctls to interact with ACRN hypervisor through different hypercalls. After the ACRN module is loaded, the device file of /dev/acrn_hsm can be accessed in user-space. It includes the management of virtualized CPU/memory/ device/interrupt/MMIO emulation for other ACRN guest. The first three patches are the changes under x86/acrn, which adds the required APIs for the driver and reports the X2APIC caps. The remaining patches add the ACRN driver module, which accepts the ioctl from user-space and then communicate with the low-level ACRN hypervisor by using hypercall.
