The "depends on ARM_DMA_USE_IOMMU & IOMMU_API" was suggested by Arnd Bergmann during code review (originally they were selected). Removing them definitely fixes the dependency recursion. Also, since they are both already selected by ROCKCHIP_IOMMU, everything will build correctly. So, this sounds good to me, but I am no expert on Kconfig. -Dan > > - Mark _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
