Message:

VMM/NEMR3Native-darwin-armv8.cpp: Need to implement our own simplistic dirty page tracking for MMIO2 regions as Hypervisor.framework doesn't work with guest page sizes but only with host page sized regions so it conflicts with our generic implementation in PGM. With that it is possible to get screen updates for guests which access the standard framebuffer and don't use the SVGA 3 interface to notify the device about dirty regions, bugref:10390
