Subject: [PATCH 16/16] amd64_edac: Disable DRAM ECC injection on K8
Date: Fri, 26 Nov 2010 20:04:23 +0100 [thread overview]
Message-ID: <1290798263-13074-17-git-send-email-bp@amd64.org> (raw)
In-Reply-To: <1290798263-13074-1-git-send-email-bp@amd64.org>
From: Borislav Petkov <borislav.petkov@amd.com>
K8 does not allow for an atomic RMW to a cacheline as GH does so disable
the error injection interface for it.
