From 17b6097753e926ca546189463070a7e94e7ea9fa Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Thu, 24 Sep 2009 12:14:00 -0700 Subject: [PATCH] intel-iommu: Decode (and ignore) RHSA entries I recently got a system where the DMAR table included a couple of RHSA (remapping hardware static affinity) entries. Rather than printing a message about an "Unknown DMAR structure," it would probably be more useful to dump the RHSA structure (as other DMAR structures are dumped).
