From: Joerg Roedel Date: Wed, 6 Apr 2011 15:26:49 +0000 (+0200) Subject: x86/amd-iommu: Cleanup completion-wait handling X-Git-Tag: v3.0-rc1~407^2~1^2~1^4~7 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=815b33fdc279d34ab40a8bfe1866623a4cc5669b;p=pandora-kernel.git x86/amd-iommu: Cleanup completion-wait handling This patch cleans up the implementation of completion-wait command sending. It also switches the completion indicator from the MMIO bit to a memory store which can be checked without IOMMU locking. As a side effect this patch makes the __iommu_queue_command function obsolete and so it is removed too. Signed-off-by: Joerg Roedel --- Reading git-diff-tree failed
