From 131c123abec375afc819da89925dbce97590278e Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Tue, 30 Sep 2014 12:38:56 +1000 Subject: powerpc/eeh: Introduce eeh_ops::err_inject The patch introduces eeh_ops::err_inject(), which allows to inject specified errors to indicated PE for testing purpose. The functionality isn't support on pSeries platform. On PowerNV, the functionality relies on OPAL API opal_pci_err_inject().
