Subject: [PATCH 3/3] iommu/vt-d: Add build dependency on IOASID
Date: Thu, 19 Mar 2020 21:32:31 -0700	[thread overview]
Message-ID: <1584678751-43169-4-git-send-email-jacob.jun.pan@linux.intel.com> (raw)
In-Reply-To: <1584678751-43169-1-git-send-email-jacob.jun.pan@linux.intel.com>

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.
