Subject: iommu/vt-d: Add build dependency on IOASID
X-Git-Tag: v5.7-rc1~46^2^7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4a663dae47316ae8b97d5b77025fe7dfd9d3487f;p=thirdparty%2Fkernel%2Flinux.git

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.
