See below.

Could you explain this document a bit. What git commands should I use to
retrive test kernel to build?
1 The vanilla boot. No IOMMU option, no SWIOTLB
http://sial.org/pbot/32038
2 with iommu=memaper=3
http://sial.org/pbot/32040
3 with iommu=memaper=3,noagp
http://sial.org/pbot/32041
4 with iommu=memaper=3,noagp,soft swiotlb=65535
http://sial.org/pbot/32042
I'm including the diff between [1] and [2]. The script I used is also
attached.
