Despite the widespread and complete failure of Broadwell integrated graphics when DMAR is enabled, known over the years, we have never been able to root cause the issue. Instead, we let the failure undermine our confidence in the iommu system itself when we should be pushing for it to be always enabled. Quirk away Broadwell and remove the rotten apple.
