Subject: [PATCH 0/4] Intel TXT driver
Date: Tue, 7 May 2013 22:55:15 +0800 [thread overview]
Message-ID: <1367938519-840-1-git-send-email-qiaowei.ren@intel.com> (raw)
This module is expected to be a better tool to access below resources
- TXT config space
- 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.
With this module, it will be easier to access TXT/tboot related
information/logs.
Qiaowei Ren (4):
driver: add TXT driver in kernel
driver: provide sysfs interfaces to access TXT config space
driver: provide sysfs interfaces to access TXT log
driver: provide sysfs interfaces to access SMX parameter
