Date: 2009-11-24 19:32 Sender: nelchael_kp I think you've just made my point clear: it needs configuration.
Date: 2009-11-24 08:53 Sender: skshandilya currently it is /dev/tpm0, If /dev/tmp0 fails we dont use the tpm. There is no configuration required.
Date: 2009-11-23 19:29 Sender: nelchael_kp Which device? /dev/tpm0, /dev/tpm1, /dev/tpm2... ?? It requires configuration anyway.

Date: 2009-11-23 19:13 Sender: nobody I disagree. If the hardware is present, enabled by BIOS, and capable of being used for this purpose, it should by default do so. People with specific concerns may disable this capability in a number of ways, but it should not be encumbant on the average user, those with no concerns about using the TPM, to recognize that it is present and take extra steps to enable it.
Date: 2009-11-23 19:11 Sender: nelchael_kp One major flaw: it should default to not using TPM, right now it's the opposite: it defaults to using it.

Date: 2009-09-25 07:38 Sender: nobody Hello jeff Please review this patch. This patch uses the random number generator inside the tpm as an entropy source in addition to the already existing sources. The ID of the patch is 2261605 http://sourceforge.net/tracker/?func=detail&aid=2261605&group_id=3242&atid=303242 regards, sandeep.
