    Subject[PATCH AUTOSEL 5.6 108/129] iommu/vt-d: Add build dependency on IOASID
    Date
    From: Jacob Pan <jacob.jun.pan@linux.intel.com>

    [ Upstream commit 4a663dae47316ae8b97d5b77025fe7dfd9d3487f ]

    IOASID code is needed by VT-d scalable mode for PASID allocation.
    Add explicit dependency such that IOASID is built-in whenever Intel
    IOMMU is enabled.
    Otherwise, aux domain code will fail when IOMMU is built-in and IOASID
    is compiled as a module.

    Fixes: 59a623374dc38 ("iommu/vt-d: Replace Intel specific PASID allocator with IOASID")
