Subject: [PATCH EDAC 08/13] ghes_edac: add support for reporting errors via EDAC
Date: Fri, 15 Feb 2013 10:44:56 -0200 [thread overview]
Message-ID: <7f8d2d0491f2abdba43bc2a8123ae360eaeb64c2.1360931635.git.mchehab@redhat.com> (raw)
In-Reply-To: <cover.1360931635.git.mchehab@redhat.com>
Now that the EDAC core is capable of just forward the errors via
the userspace API, add a report mechanism for the GHES errors.
