Re: [PATCH v4 0/5] iommu/amd: Convert the AMD iommu driver to the dma-iommu api
Done, I just sent it there. I don't have any AMD hardware to test on while I'm traveling. However the rebase was very straightforward and the code was tested a month ago on the old linux-next. I only have the AMD conversion done. I will work on rebasing the intel one when I get a chance.

It isn't in any strict sense urgent. I just have various DMA API plans that I'd rather just implement in dma-direct and dma-iommu rather than also in two additional commonly used iommu drivers.

Hi Christoph, I quit my job and am having a great time traveling South East Asia. I definitely don't want this work to go to waste and I hope to repost it later this week but I can't guarantee it. Let me know if you need this urgently.

[PATCH v4 0/5] iommu/amd: Convert the AMD iommu driver to the dma-iommu api
Convert the AMD iommu driver to the dma-iommu api. Remove the iova handling and reserve region code from the AMD iommu driver. Change-log: V4: -Rebase on top of linux-next -Split the removing of the unnecessary locking in the amd iommu driver into a seperate patch -refactor the "iommu/dma-iommu: Handle deferred devices" patch and address comments v3: -rename dma_limit to dma_mask -exit handle_deferred_device early if (!is_kdump_kernel()) -remove pointless calls to handle_deferred_device v2: -Rebase on top of this series: http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/dma-iommu-ops.3 -Add a gfp_t parameter to the iommu_ops::map function. -Made use of the reserve region code inside the dma-iommu api Tom Murphy (5): iommu/amd: Remove unnecessary locking from AMD iommu driver iommu: Add gfp parameter to iommu_ops::map iommu/dma-iommu: Handle deferred devices iommu/dma-iommu: Use the dev->coherent_dma_mask iommu/amd: Convert AMD iommu driver to the dma-iommu api drivers/iommu/Kconfig | 1 + drivers/iommu/amd_iommu.c | 690 drivers/iommu/amd_iommu_types.h | 1 - drivers/iommu/arm-smmu-v3.c | 2 +- drivers/iommu/arm-smmu.c| 2 +- drivers/iommu/dma-iommu.c | 45 ++- drivers/iommu/exynos-iommu.c| 2 +- drivers/iommu/intel-iommu.c | 2 +- drivers/iommu/iommu.c | 43 +- drivers/iommu/ipmmu-vmsa.c | 2 +- drivers/iommu/msm_iommu.c | 2 +- drivers/iommu/mtk_iommu.c | 2 +- drivers/iommu/mtk_iommu_v1.c| 2 +- drivers/iommu/omap-iommu.c | 2 +- drivers/iommu/qcom_iommu.c | 2 +- drivers/iommu/rockchip-iommu.c | 2 +- drivers/iommu/s390-iommu.c | 2 +- drivers/iommu/tegra-gart.c | 2 +- drivers/iommu/tegra-smmu.c | 2 +- drivers/iommu/virtio-iommu.c| 2 +- include/linux/iommu.h | 21 +- 21 files changed, 179 insertions(+), 652 deletions(-) -- 2.20.1 ___ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization

Tom, please rebase and resubmit this series after the next merge window and I will do more performance testing on it. If all goes well I and no other issues show up I can apply it for v5.4.

Tom, next time please cc Jerg as the AMD IOMMU maintainer. Joerg, any chance you could review this? Toms patches to convert the AMD and Intel IOMMU drivers to the dma-iommu code are going to make my life in DMA land significantly easier, so I have a vested interest in this series moving forward :) ___ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
