There is no good reason to not define ARCH_HAS_SG_CHAIN. To fix your immediate problem just select it from riscv, as riscv uses the generic dma-direct code which is chained S/G safe by definition. And if you want to get extra points do a quick audit of the remaning iommu drivers on architectures that don't define it so that we can kill the symbol. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
