Subject: [patch 0/2] Intel IOMMU Suspend/Resume Support
Date: Wed, 25 Mar 2009 11:45:48 -0700 [thread overview]
Message-ID: <20090325184548.012018000@intel.com> (raw)
Current Intel IOMMU does not support suspend and resume. In S3 event, kernel
crashes when IOMMU is enabled. The attached patch set implements the suspend and
resume feature for Intel IOMMU. It hooks to kernel suspend and resume interface.
When suspend happens, it saves necessary hardware registers. When resume happens
it restores the registers and restarts IOMMU.
This patch set is applied to the tip tree.
