I hope someone can help to explain the difference Intel VT-d2 and Intel VT-d.
it confuse me.
As I know :
— Original Intel VT-d features
— Improved invalidation architecture
— End point caching support (ATS)
— Interrupt remapping
— 4K/2M/1G super page support
(From Grantley Haswell V3 EDS1)
Could I talk it, Intel VT-d2 is the improved Intel VT-d technology for Grantley platform, just like (Intel® I/OAT)4 for Grantley, is it right?
VT-d stands for Intel® Virtualization for Directed I/O. "VT-d2" appears to be an informal and internal name for Intel® Core i7 Processor VT-d capabilities. Included in these capabilities are (a) I/O device assignment, (b) DMA remapping, (c) interrupt remapping, and (d) reliability features.
