Subject: [PATCH v11 08/10] powerpc/powernv: Thread IMC events detection
Date: Thu, 29 Jun 2017 00:27:11 +0530 [thread overview]
Message-ID: <1498676232-23841-7-git-send-email-anju@linux.vnet.ibm.com> (raw)
In-Reply-To: <1498676232-23841-1-git-send-email-anju@linux.vnet.ibm.com>
Code to add support for detection of thread IMC events. It adds a new
domain IMC_DOMAIN_THREAD and it is determined with the help of the
"type" property in the imc device-tree.
