    SVM Atomic is unsupported




      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 !
