Ok done.. bisect points to:
What is the failure mode you are seeing? Can't find anything in the mail unfortunately.
As far as I analyzed it we now get an -ENOMEM from dma_alloc_attrs() in drivers/gpu/drm/ttm/ttm_page_alloc_dma.c when IOMMU is enabled.
Still need to figure out which parameters we want to use for the allocation, but I think it is only 4k or 8k.
When you guys need me to test something , or run debug patches or patches of any sort just let me know..
