[vbox-dev] How to access host vertical blanking intervals

Hello VBOX developers,
I recently contributed a patch to in-kernel vboxvideo DRM driver which
adds support for page flip. However the implementation does not
make any attempt to sync page flip with host vertical blanking
interval, so it's possible a DRM page flip will result in tearing artifacts.
So is there a call that can be made into the hypervisor that would allow
receiving an event when host display has entered a vblank interval?
Something in the VBOX Main API perhaps?
Thanks in advance,
