intel_gvt_schedule check timer through a counter and is supposed to wake up to increase the counter every ms. In a system with heavy workload, gvt_service_thread can not get a chance to run right after wake up and will be delayed several milliseconds. As a result, one hundred counter interval means several hundred milliseconds in real time. This patch use real time instead of counter to do timer check. v2: remove static variable. (Zhenyu) v3: correct expire_time update.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
