From: Joerg Roedel Date: Tue, 27 Jul 2010 15:14:24 +0000 (+0200) Subject: x86/amd-iommu: Export cache-coherency capability X-Git-Tag: v2.6.36-rc1~534^2^3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=80a506b8fdcfa868bb53eb740f928217d0966fc1;p=pandora-kernel.git x86/amd-iommu: Export cache-coherency capability This patch exports the capability of the AMD IOMMU to force cache coherency of DMA transactions through the IOMMU-API. This is required to disable some nasty hacks in KVM when this capability is not available. Signed-off-by: Joerg Roedel --- Reading git-diff-tree failed
