From 4a663dae47316ae8b97d5b77025fe7dfd9d3487f Mon Sep 17 00:00:00 2001 From: Jacob Pan Date: Thu, 19 Mar 2020 21:32:31 -0700 Subject: iommu/vt-d: Add build dependency on IOASID 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.
