Subject: [PATCH] Intel IOMMU: RMRRs do not necessarily have to be present on all VT-d capable platforms
Date: Tue, 1 Jul 2008 05:13:54 -0400 [thread overview]
Message-ID: <20080701091354.GA12969@ywang-dev> (raw)
RMRRs do not necessarily have to be present on all VT-d capable platforms.
The printk is just informational and does not need to be followed by an
error return.
