Ben, It looks like this patch has bit rot. I have a system now where I can test the latest version. Any chance you can rediff and resend and I can test? Thanks, Brian ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org

[PATCH 3/3] powerpc/iommu: Support hybrid iommu/direct DMA ops for coherent_mask dma_mask

2015-06-23 Thread Benjamin Herrenschmidt
This patch adds the ability to the DMA direct ops to fallback to the IOMMU ops for coherent alloc/free if the coherent mask of the device isn't suitable for accessing the direct DMA space and the device also happens to have an active IOMMU table. Signed-off-by: Benjamin Herrenschmidt
