Subject: [PATCH 2/3] powerpc/eeh: Don't remove passed VFs
Date: Fri, 26 Feb 2016 11:04:51 +1100 [thread overview]
Message-ID: <1456445092-18337-3-git-send-email-gwshan@linux.vnet.ibm.com> (raw)
In-Reply-To: <1456445092-18337-1-git-send-email-gwshan@linux.vnet.ibm.com>
When we have partial hotplug as part of the error recovery on PF,
the VFs that are bound with vfio-pci driver will experience hotplug.
That's not allowed.
This checks if the VF PE is passed or not. If it does, we leave
the VF without removing it.
