Abstract
A system and method including, in some embodiments, receiving a request for a graphics memory address for an input/output (I/O) device assigned to a virtual machine in a system that supports virtualization, and installing, in a graphics memory translation table, a physical guest graphics memory address to host physical memory address translation.
Claims28
A method comprising:
- receiving a request for a guest graphics memory address for an input/output (I/O) device assigned to a virtual machine in a system that supports virtualization;
- and
- installing, in a graphics memory translation table, a physical guest graphics memory address to host physical memory address translation.
A system comprising:
- an input/output (I/O) device assigned to a virtual machine in a system that supports virtualization;
- a graphics memory translation table to associate a physical guest graphics memory address with a host physical address;
- a graphics memory unit;
- and
- a memory associated with the graphics memory unit and storing instructions that when executed by a machine result in the following:
- installing, in the graphics memory translation table, a physical guest graphics memory address to host physical memory address translation.
