Subject: [PATCH v2 3/7] platforms/pseries: Set eeh_pe of EEH_PE_VF type
Date: Mon, 18 Dec 2017 16:38:04 -0600	[thread overview]
Message-ID: <20171218223808.83928-4-bryantly@linux.vnet.ibm.com> (raw)
In-Reply-To: <20171218223808.83928-1-bryantly@linux.vnet.ibm.com>

To correctly use EEH code one has to make
sure that the EEH_PE_VF is set for dynamic created
VFs. Therefore this patch allocates an eeh_pe of
eeh type EEH_PE_VF and associates PE with parent.
