Subject: [PATCH 15/16] AMD IOMMU: fix device table entry size
Date: Fri, 11 Jul 2008 17:14:34 +0200 [thread overview]
Message-ID: <1215789275-20975-16-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1215789275-20975-1-git-send-email-joerg.roedel@amd.com>
A device table entry is actually only 256 *bits* large. Not 256 bytes.
