Re: [tboot-devel] Nehalem and TXT roadmap

[Cihula, J. <jos...@in...>]

Martin,

 

Intel(r) TXT is one of the component of the vPro(tm) brand, beginning
with this year's client platforms.  So any vPro client (mobile or
desktop) this year will have TXT.  We did not have any TXT-specific
sessions at this Fall's IDF, though we did have a panel discussion on
Trusted Computing, which included a lot of discussion about TXT.

 

As the '08 vPro platforms are not yet available, the only ones that
support TXT now are the Weybridge-based (Q35/X38 Express chipset)
systems.  Both the new mobile and desktop chipsets (codenames Cantiga
and Eaglelake; not sure what their official names will be) that will
come out in a few months will support TXT.

 

You are right that TXT requires a TPM on the platform.  The TPM could
either be discrete (a separate part as currently used) or integrated.
The new chipsets will include an integrated TPM, though it is up to the
system manufacturer to decided whether to enable it.

Subject: [tboot-devel] Nehalem and TXT roadmap

 

Hello,

 

Unfortunately I wasn't able to attend the IDF but I understand there was
a lot of talk about Nehalem. Was there any talk about TXT in this
context? Is TXT supported by Nehalem and is there any enhancements to
the technology? Also, what chipsets supports TXT and does Intel plan to
ship any motherboards with those chipsets equipped for TXT? I suppose
the latter would be with a TPM onboard although there have been rumours
that future Intel chipsets will feature integrated TPM's (however it is
easy to see how a journalist could confuse chipset support for TXT/TPM
with an integrated TPM).

Perhaps some of the people from Intel could reveal a bit about Intel's
"roadmap" for TXT, both from the hardware and software side of things.
Thanks! :)

 

 

Best regards,
