Subject: [PATCH 3/6] tpm_tis: set timeouts before calling request_locality
Date: Tue, 30 Jun 2009 18:04:12 -0700 [thread overview]
Message-ID: <1246410255-6839-4-git-send-email-adi@vmware.com> (raw)
In-Reply-To: <1246410255-6839-1-git-send-email-adi@vmware.com>
On Intel iTPM implementations, the timeouts must be set before
calling request_locality.
Based on a patch from Colin Didier and the tpmdd-devel mailing list:
http://cybione.org/~cdidier/log/data/200812020841/itpm.diff
