Revision 8aafaaf2212192012f5bae305bb31cdf7681d777 authored by Joerg Roedel on 28 March 2019, 10:44:59 UTC, committed by Joerg Roedel on 29 March 2019, 16:12:57 UTC
If a device has an exclusion range specified in the IVRS
table, this region needs to be reserved in the iova-domain
of that device. This hasn't happened until now and can cause
data corruption on data transfered with these devices.
Treat exclusion ranges as reserved regions in the iommu-core
to fix the problem.
Fixes: be2a022c0dd0 ('x86, AMD IOMMU: add functions to parse IOMMU memory mapping requirements for devices')
