This module is expected to be a better tool to access below resources - TXT config space - TXT heap - Tboot log mem - SMX parameter
Intel TXT (Trusted Execution Technology) will provide higher assurance of system configuration and initial state as well as data reset protection. It also helps solve real end user concerns about having confidence that their hardware is running the VMM or kernel that it was configured with, especially since they may be responsible for providing such assurances to VMs and services running on it. See <http://www.intel.com/technology/security/> for more information about Intel(R) TXT. Intel TXT configuration registers are a subset of chipset registers. These chipset registers that interact with SMX are accessed from two regions of memory, which represent the public and private configuration spaces, by system software using memory read/write protocols. Intel TXT Heap memory is a region of physically contiguous memory which is set aside by BIOS for the use of Intel TXT hardware and software. With this module, it will be easier to access TXT/tboot related information/logs.
