Jian Jun Chen 94dadc1d14 dm: virtio-input: ignore MSC_TIMESTAMP from guest (EV_MSC, MSC_TIMESTAMP) is added to each frame just before the SYN event since kernel 4.15. EV_MSC is configured as INPUT_PASS_TO_ALL. In the use case of virtio-input, there is a loop as follows: - A mt frame with (EV_MSC, MSC_TIMESTAMP) is passed to FE. - FE will call virtinput_status to pass (EV_MSC, MSC_TIMESTAMP) back to BE. - BE writes this event to evdev. Because (EV_MSC, MSC_TIMESTAMP) is configured as INPUT_PASS_TO_ALL, it will be written into the event buffer of evdev then be read out by BE without SYN followed. - Each mt frame will introduce one (EV_MSC, MSC_TIMESTAMP). Later the frame becomes larger and larger... This patch fixed above issue by ignoring MSC_TIMESTAMP from guest. Besides that timestamp is added for every status event from guest before writing to evdev.

ACRN Device Model
#################

Introduction
============
The ACRN Device Model provides **device sharing** capabilities between the Service OS and Guest OSs. It is a component that is used in conjunction with the `ACRN Hypervisor`_ and this is installed within the Service OS. You can find out more about Project ACRN on the `Project ACRN documentation`_ website.
