From mboxrd@z Thu Jan 1 00:00:00 1970 From: mathieu.poirier@linaro.org (mathieu.poirier at linaro.org) Date: Wed, 20 Aug 2014 11:03:50 -0600 Subject: [PATCH 10/11 v4] coresight: adding basic support for Vexpress TC2 In-Reply-To: <1408554231-24321-1-git-send-email-mathieu.poirier@linaro.org> References: <1408554231-24321-1-git-send-email-mathieu.poirier@linaro.org> Message-ID: <1408554231-24321-11-git-send-email-mathieu.poirier@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Mathieu Poirier Support for the 2 PTMs, 3 ETMs, funnel, TPIU and replicator connected to the ETB are included. Proper handling of the ITM and the replicator linked to it along with the CTIs and SWO are not included.
