From: Alex Williamson Date: Fri, 21 Oct 2011 19:56:24 +0000 (-0400) Subject: iommu: Add option to group multi-function devices X-Git-Tag: v3.3-rc1~120^2^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bcb71abe7d4c5a0d0368c67da0a7def4fc73497a;p=pandora-kernel.git iommu: Add option to group multi-function devices The option iommu=group_mf indicates the that the iommu driver should expose all functions of a multi-function PCI device as the same iommu_device_group. This is useful for disallowing individual functions being exposed as independent devices to userspace as there are often hidden dependencies. Virtual functions are not affected by this option.
