This patch adds TCG BIOS extensions to the high memory area along with some often-used libc utility functions. The TCG extensions are described here: https://www.trustedcomputinggroup.org/specs/PCClient/TCG_PCClientImplementationforBIOS_1-20_1-00.pdf I have tried to keep the patching with rombios.c to a minimum, but some amount of code needs to be inserted at various locations. The code is currently deactivated, but can be activated by setting BX_TCGBIOS to ''1'...

...implementation of the TCG BIOS extensions to the Bochs BIOS and enables logging of boot measurements using the previously implemented support for TCPA ACPI tables. A low-level driver for a TPM TIS device and an Atmel device is provided. The implemented specification is described here: https://www.trustedcomputinggroup.org/specs/PCClient/TCG_PCClientImplementationforBIOS_1-20_1-00.pdf I added a #define ''BX_TCGBIOS'' to rombios.c that enables or disables these extensions. It''s currently disabled so none of the code is compiled into the BIOS. The implementation passes the tests implement...

...t will require changes to the virtual TPM spawned by the vTPM manager to offer an additional message interface. The TIS interface itself then needs to have an additional transport implemented. (see vTPMTransmit array).

Hello everyone, I am sorry for interrupting your work I am following the correspondence in silence. I am trying to build a vtpm implementation into xen 6.2 but I was not able to find all the means to do it. What can be found is just abstract knowledge. Most of the info always forwards me to this doc

whats the state of support for self-encrypting drives in CentOS 6 ? these are becoming increasingly common on both laptops and for enterprise storage (particularlly nearline), with features like instant-erase via key destruction. -- john r pierce N 37, W 122 santa cruz ca mid-left coast

That's a great question, actually, I should have remembered to mention that! You can control what factors are used for the TPM's integrity check to release the bitlocker key on boot. Depending on whether your on a BIOS or EFI machine, there are slight differences, but definitely controllable by group policy. http://technet.microsoft.com/en-us/library/ee706521(v=ws.10).aspx#BKMK_depopt3 I
