Hi,

I think it is a good idea to have a way to check for the presence of
TXT in your machine without having to look at BIOS setup.

Enclosed is a small module named "txt". You can compile it, and load
it in ("insmod txt.ko"). Check for the presence of TXT by looking for
the message "TXT chipset and all needed capabilities present" in
output of "dmesg". If you don't see that, your machine doesn't support
TXT. See a little README in the attachment.

Note: load the module inside native Linux kernel, but *not* in Xen.

The module code is shamelessly lifted from Joseph's patch :-)


This module is helpful, and it can detect TXT on my machine. Thanks!

Jun.
