Zach Reizner 79b2a73272 sys_util: move handle_eintr!() to sys_util so it can be reused 
This CL takes the handle_intr!() macro, changes its name to
handle_eintr!(), and overloads it so it can handle EINTR embedded in
other kinds of Result types.

BUG=None
TEST=cargo test

Chrome OS KVM

This component, known as crosvm, runs untrusted operating systems along with virtualized devices. No actual hardware is emulated. This only runs VMs through the Linux's KVM interface. What makes crosvm unique is a focus on safety within the programming language and a sandbox around the virtual devices to protect the kernel from attack in case of an exploit in the devices.

Overview

The crosvm source code is organized into crates, each with their own unit tests. These crates are:

  • kvm-sys low-level (mostly) auto-generated structures and constants for using KVM
  • kvm unsafe, low-level wrapper code for using kvm-sys
  • crosvm the top-level binary front-end for using crosvm

Usage

Currently there is no front-end, so the best you can do is run cargo test in each crate.
