<blockquote> This patch series adds support for SMMU passthrough using the default domain,
the patch series implements a kernel command-line option iommu.passthrough=0/1
1 - Bypass the IOMMU for DMA, 0 - Use IOMMU translation for DMA. This feature
is desired on both Qualcomm Centriq 2400 and Thunder-X platforms.
The bug report <a href="http://bugs.launchpad.net/bugs/1688158">http://bugs.launchpad.net/bugs/1688158</a> has detailed test results
from Qualcomm demonstrating performance improvements using passthrough. I have
also tested the kernel on Thundex-X for any regressions, for both boot test and
pci passthrough.
Please review and consider for SRU.
