Changeset 106957 in vbox for trunk/include/VBox/platforms/vbox-armv8.h

Timestamp:

165884

Message:

Main/ResourceAssignmentManager: Rewrite to accomodate for the fact that Windows guests have several requirements on where devices are located (TPM needs to be at fixed 0xfed40000, PL061 GPIO driver doesn't support 64bit MMIO, the GIC re-disitributor emulated by Hyper-V requires 128KiB of MMIO space rather than the 64KiB we currently reserve). This will break saved state compatibility (whether we want to restore this functionality is up for discussion), bugref:10732
