ACRN is a flexible, lightweight reference hypervisor, built with real-time and safety-criticality in mind, optimized to streamline embedded development through an open source platform. 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 allows the Linux to work on ACRN hypervisor and it can work with the following patch set to manage the Linux guest on acrn-hypervisor. It includes the detection of acrn_hypervisor, upcall notification vector from hypervisor, hypercall. The hypervisor detection is similar to Xen/VMWARE/Hyperv. ACRN also uses the upcall notification mechanism similar to that in Xen/Microsoft HyperV when it needs to send the notification to Linux OS. The hypercall provides the mechanism that can be used to query/configure the acrn-hypervisor by Linux guest.
Following this patch set, we will send acrn driver part, which provides the interface that can be used to manage the virtualized CPU/memory/device/interrupt for other guest OS after the acrn hypervisor is detected.
v1->v2: Change the CONFIG_ACRN to CONFIG_ACRN_GUEST, which makes it easy to understand. Remove the export of x86_hyper_acrn. Remove the unused API definition of acrn_setup_intr_handler and acrn_remove_intr_handler. Adjust the order of header file Add the declaration of acrn_hv_vector_handler and tracing definition of acrn_hv_callback_vector. Refine the comments for the function of acrn_hypercall0/1/2
