•Large
Intel VT-d Pages
•Adds
2 MB and 1 GB page sizes to Intel VT-d implementations
•Matches
current support for Extended Page Tables (EPT)
•Ability
to share CPU’s EPT
page-table(with super-pages) with Intel VT-d
•Benefits:
•Less
memory foot-print for I/O page-tables when using super-pages
•Potential
for improved performance – Due to shorter page-walks, allows hardware
optimization for IOTLB
•Transition
latency reductions expected to improve virtualization performance without the
need for VMM enabling. This reduces the VMM overheads further and increase
virtualization performance
