I've got patches pending to replace all that code with dma_direct_alloc, which will do the right thing. They were submitted for 4.16, and I will resend them after -rc1.I see, thanks Christoph !Hi Christoph It seems 4.16 has shipped ( :) ) , and intel_alloc_coherent() still has no NUMA awareness.
Actually, that code went in and then got reverted again..
Should I respin https://lore.kernel.org/patchwork/patch/884326/
Maybe. We are still hoping to convert intel-iommu to the dma-iommu framework, but I'm not sure how long that is going to take, so maybe just respin it for now.
