[Qemu-devel] [PATCH v2 0/5] [RFC] Add HAX support |

I took a stab at trying to rebase/upstream the support for Intel HAXM.
(Hardware Accelerated Execution Manager).
Intel HAX is kernel-based hardware acceleration module for Windows and MacOSX.
I have based my work on the last version of the source code I found:
the emu-2.2-release branch in the external/qemu-android repository as used by
the Android emulator.
In patch 2/5, I have forward-ported the core HAX code mostly unmodified from
there, I just did some minor touch up to make it build and run properly,
and fixed the style issues to go through checkpatch.pl.
I have not included the Darwin support.
It might contain some outdated constructs and probably requires more
attention (thus the 'RFC' for this patchset).
In patch 3/5, I'm removing a good chunk of the support for CPUs without UG mode
as advised by Paolo to simplify the initial version.
In patch 5/5, I have put the plumbing into the QEMU code base, I did some clean
up there and it is reasonably intrusive: i.e.

The qemu_cpu_kick_thread mess in cpus.c is probably still not perfact though.
The patch 1/5 just extracts from KVM specific header the cpu_synchronize_
functions that HAX is also using.
I have tested the end result on a Windows 10 Pro machine (with UG support)
with the Intel HAXM module 6.0.4 and a large ChromiumOS x86_64 image to
exercise various code paths. It looks stable.
I also did a quick regression testing of the integration by running a Linux
build with KVM enabled.
Changes from v1 to v2:
- fix all style issues in the original code to get it through checkpatch.pl.
- remove Darwin support, it was barely tested and not fully functional.
- remove the support for CPU without UG mode.
- fix most review comments
Vincent Palatin (5):
kvm: move cpu synchronization code
target-i386: Add Intel HAX files
hax: remove non UG code
hax: simplify init
Plumb the HAXM-based hardware acceleration support
