Problem: Broken bios creates inaccurate DMAR tables, reporting some bridges as having endpoint types. This causes IOMMU initialization to bail out early with an error code, the result of which is vfio not working correctly. This is seen on some Skylake based Wolfpass server platforms with up-to-date bios installed. Solution: Instead of just bailing out of IOMMU initialization when such a condition is found, we report it and continue. The IOMMU ends up successfully initialized anyway. We do this only on platforms that have the Skylake bridges where this issue has been seen. This change is inspired by a similar one posted by Lu Baolu of Intel Corp to lkml https://lkml.org/lkml/2019/12/24/15 Change-Id: Ief2df7099b6118eab7f99d5531616926a7a3eb27 Closes-Bug: 1847335 Signed-off-by: Jim Somerville <Jim.Somerville@windriver.com>
