From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alexander Steffen Subject: [PATCH v2 1/3] tpm2-cmd: Trigger only missing self tests Date: Thu, 24 Aug 2017 10:30:04 +0200 Message-ID: <20170824083006.7704-2-Alexander.Steffen@infineon.com> References: <20170824083006.7704-1-Alexander.Steffen@infineon.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <20170824083006.7704-1-Alexander.Steffen-d0qZbvYSIPpWk0Htik3J/w@public.gmane.org> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: tpmdd-devel-bounces-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org To: jarkko.sakkinen-VuQAYsv1563Yd54FQh9/CA@public.gmane.org, tpmdd-devel-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org List-Id: tpmdd-devel@lists.sourceforge.net tpm2_do_selftest is only used during initialization of the TPM to ensure that the device functions correctly. Therefore, it is sufficient to request only missing self tests (parameter full_test=0), not a reexecution of all self tests, as was done before. This allows for a faster execution of this command.
