crypto: ccp - Fix DMA operations when IOMMU is enabled 2017-02-14T23:25:33+00:00 Gary R Hook gary.hook@amd.com 2017-01-27T21:28:45+00:00 1105ccf25118894ffde5b50d43c52b9e39fe3fc9 commit 500c0106e638e08c2c661c305ed57d6b67e10908 upstream. An I/O page fault occurs when the IOMMU is enabled on a system that supports the v5 CCP. DMA operations use a Request ID value that does not match what is expected by the IOMMU, resulting in the I/O page fault. Setting the Request ID value to 0 corrects this issue.
