Intel i5-2435M AV8062700995706 Data Sheet

•

Memory controller and processor graphics comply with the Intel VT-d 1.2

Specification

•

Two Intel VT-d DMA remap engines
— iGFX DMA remap engine
— Default DMA remap engine (covers all devices except iGFX)

•

Support for root entry, context entry, and default context

•

39-bit guest physical address and host physical address widths

•

Support for 4 KB, 2 MB, and 1 GB page sizes

•

Support for register-based fault recording only (for single entry only) and support

for MSI interrupts for faults

•

Support for both leaf and non-leaf caching

•

Support for boot protection of default page table

•

Support for non-caching of invalid page table entries

•

Support for hardware-based flushing of translated but pending writes and pending

reads, on IOTLB invalidation

•

Support for Global, Domain specific, and Page specific IOTLB invalidation

•

MSI cycles (MemWr to address FEEx_xxxxh) not translated
— Translation faults result in cycle forwarding to VBIOS region (byte enables

masked for writes). Returned data may be bogus for internal agents; PEG/DMI

interfaces return unsupported request status

•

Interrupt remapping is supported

•

Queued invalidation is supported

•

Intel VT-d translation bypass address range is supported (Pass Through)

The processor supports the following added new Intel VT-d features:
•

Intel VT-d superpage: support of Intel VT-d superpage (2 MB, 1 GB) for the

default Intel VT-d engine and Intel VT-D IGD engine (iGFX DMA remap engine

•

Support for LPSS device virtualization

Intel VT-d Technology may not be available on all SKUs.

Intel Trusted Execution Technology (Intel TXT) defines platform-level enhancements

that provide the building blocks for creating trusted platforms.

The Intel TXT platform helps to provide the authenticity of the controlling environment

such that those wishing to rely on the platform can make an appropriate trust

decision. The Intel TXT platform determines the identity of the controlling environment

by accurately measuring and verifying the controlling software.

Another aspect of the trust decision is the ability of the platform to resist attempts to

change the controlling environment. The Intel TXT platform will resist attempts by

software processes to change the controlling environment or bypass the bounds set by

the controlling environment.
