Linux kernel source tree

Now mmio switch between vGPUs need to switch to host first then to expected vGPU, it waste one time mmio save/restore. r/w mmio usually is time-consuming, and there are so many mocs registers need to save/restore during vGPU switch. Combine the switch_to_host and switch_to_vgpu can reduce 1 time mmio save/restore, it will reduce the CPU utilization and performance while there is multi VMs with heavy work load.

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.
