From: Gavin Shan Date: Thu, 20 Jun 2013 05:21:07 +0000 (+0800) Subject: powerpc/eeh: I/O chip post initialization X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=73370c662b4e453185201b44b775a49e95870009;p=deliverable%2Flinux.git powerpc/eeh: I/O chip post initialization The post initialization (struct eeh_ops::post_init) is called after the EEH probe is done. On the other hand, the EEH core post initialization is designed to call platform and then I/O chip backend on PowerNV platform. The patch adds the backend for I/O chip to notify the platform that the specific PHB is ready to supply EEH service.
