Subject: [PATCH v3 2/6] powerpc/powernv: Allow to freeze PE
Date: Mon, 21 Jul 2014 14:42:31 +1000 [thread overview]
Message-ID: <1405917755-28830-3-git-send-email-gwshan@linux.vnet.ibm.com> (raw)
In-Reply-To: <1405917755-28830-1-git-send-email-gwshan@linux.vnet.ibm.com>
The patch synchronizes header file with firmware to have new OPAL
API opal_pci_eeh_freeze_set(), which is used to freeze the specified
PE in order to support "compound" PE.
Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com>
