About the 2 MM IOMMU HW, the connection could be something like this: IOMMU(VDO) IOMMU(VPP) | | SMI_COMMON(VDO) SMI_COMMON(VPP) --------------- ---------------- | | ... | | ... larb0 larb2 ... larb1 larb3 ... INFRA IOMMU does not have SMI, the master connects to IOMMU directly. Although multiple banks supported in MT8188, we only use one of them, which means PCIe is put in bank0 of INFRA IOMMU. So we have two pgtable for MT8188, specifically, these two MM IOMMU HW share a pgtable while INFRA IOMMU HW use a independent pgtable. Another change is that we add some SMC command for INFRA master to enable/disable INFRA IOMMU in ATF considering security concerns. We also adjust the flow of mtk_iommu_config to reduce indention. change since v8: - Base on v6.3-rc1 and mtk-iommu-dma-range-v5: https://lore.kernel.org/linux-mediatek/20230307023507.13306-1-yong.wu@mediatek.com/ - Add a new patch set_dma_mask since mt8188 support the PA of pgtable 35bits. changes since v7: - Base on mtk-iommu-dma-range-v4: https://lore.kernel.org/linux-mediatek/20230215062544.8677-1-yong.wu@mediatek.com/ - Add a new patch for two IOMMU share pagetable issue. - Add a new patch for adding iova_region_larb_msk for mt8188. - Add the comment in the dt-binding header file about larb index. This is for readable when updating the iova_region_larb_msk. Since there is something wrong for chengci's mail account when sending to devicetree mail list, we don't know why.
