SVM Atomic is unsupported

Hello,

Several days ago, programs with SVM atomic buffer worked correctly on my Kaveri platform.

But recently, after I use a 10Gbps NIC, IOMMU reports IO_PAGE_FAULT and the network becomes unavailable.

And when I try to run the program with SVM atomic buffer, it reports that "Unsupported device! Device does not support SVM Atomics".

I enter the BIOS and find that the IOMMU is disabled, so I enable the IOMMU. But unfortunately, the program still reports SVM atomic is unsupported.

My platform is Kaveri + ubuntu15.04 (64-bit), and any help will be greatly appreciated !
