[RFC PATCH 04/15] drivers/acrn: add the basic framework of acrn char device driver

2019-08-15 Thread Zhao Yakui
ACRN hypervisor service module is the important middle layer that allows the Linux kernel to communicate with the ACRN hypervisor. It includes the management of virtualized CPU/memory/device/interrupt for other ACRN guest. The user-space applications can use the provided ACRN ioctls to interact wit
