Sergio Andres Gomez Del Real c97d6d2cdf i386: hvf: add code base from Google's QEMU repository This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State ' instead of 'CPUState ' so we don't have to get the 'env'.
