2018-03-06WHPX improve interrupt notification registrationJustin Terry (VM) via Qemu-devel
Improves the usage of the InterruptNotification registration by skipping the additional call to WHvSetVirtualProcessorRegisters if we have already registered for the window exit.

2018-03-06WHXP Removes the use of WHvGetExitContextSizeJustin Terry (VM) via Qemu-devel
The use of WHvGetExitContextSize will break ABI compatibility if the platform changes the context size while a qemu compiled executable does not recompile. To avoid this we now use sizeof and let the platform determine which version of the struction was passed for ABI compatibility.

2018-03-06Fix WHPX issue leaking tpr valuesJustin Terry (VM) via Qemu-devel
Fixes an issue where if the tpr is assigned to the array but not a different value from what is already expected on the vp the code will skip incrementing the reg_count. In this case its possible that we set an invalid memory section of the next call for DeliverabilityNotifications that was not expected. The fix is to use a local variable to store the temporary tpr and only update the array if the local tpr value is different than the vp context.

2018-03-06Fix WHPX additional lock acquisitionJustin Terry (VM) via Qemu-devel
The code already is holding the qemu_mutex for the IO thread. We do not need to additionally take the lock again in this case.

2018-03-06Remove unnecessary WHPX __debugbreak();Justin Terry (VM) via Qemu-devel
Minor code cleanup. The calls to __debugbreak() are not required and should no longer be used to prevent unnecessary breaks.

2018-03-06Fixing WHPX casing to match SDKJustin Terry (VM) via Qemu-devel
Fixes an issue where the SDK that was releases had a different casing for the *.h and *.lib files causing a build break if linked directly from Windows Kits.

2018-02-07Introduce the WHPX implJustin Terry (VM)
Implements the Windows Hypervisor Platform accelerator (WHPX) target. Which acts as a hypervisor accelerator for QEMU on the Windows platform. This enables QEMU much greater speed over the emulated x86_64 path's that are taken on Windows today. 1. Adds support for vPartition management. 2. Adds support for vCPU management. 3. Adds support for MMIO/PortIO. 4. Registers the WHPX ACCEL_CLASS.
