      powerpc/vfio: Enable on PowerNV platform · 4e13c1ac
      Alexey Kardashevskiy authored
      This initializes IOMMU groups based on the IOMMU configuration
      discovered during the PCI scan on POWERNV (POWER non virtualized)
      platform.  The IOMMU groups are to be used later by the VFIO driver,
      which is used for PCI pass through.
      It also implements an API for mapping/unmapping pages for
      guest PCI drivers and providing DMA window properties.
      This API is going to be used later by QEMU-VFIO to handle
      h_put_tce hypercalls from the KVM guest.
      The iommu_put_tce_user_mode() does only a single page mapping
      as an API for adding many mappings at once is going to be
      added later.
      Although this driver has been tested only on the POWERNV
      platform, it should work on any platform which supports
      TCE tables.  As h_put_tce hypercall is received by the host
      kernel and processed by the QEMU (what involves calling
      the host kernel again), performance is not the best -
      circa 220MB/s on 10Gb ethernet network.
      To enable VFIO on POWER, enable SPAPR_TCE_IOMMU config
      option and configure VFIO as required.

      POWERPC: drivers: remove __dev* attributes. · cad5cef6
      Greg Kroah-Hartman authored
      CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
      markings need to be removed.
      This change removes the use of __devinit, __devexit_p, __devinitdata,
      __devinitconst, and __devexit from these drivers.
      Based on patches originally written by Bill Pemberton, but redone by me
      in order to handle some of the coding style issues better, by hand.
