Iglesias" , Prem Mallappa RFC -> v1: - As per SMMUv3 spec 16.0 (only is_ste_consistant() is noticeable) - Reworked register access/update logic - Factored out translation code for - single point bug fix - sharing/removal in future - (optional) Unit tests added, with PCI test device - S1 with 4k/64k, S1+S2 with 4k/64k - (S1 or S2) only can be verified by Linux 4.7 driver - (optional) Priliminary ACPI support RFC: - Implements SMMUv3 spec 11.0 - Supported for PCIe devices, - Command Queue and Event Queue supported - LPAE only, S1 is supported and Tested, S2 not tested - BE mode Translation not supported - IRQ support (legacy, no MSI) - Tested with DPDK and e1000 Patch 1: Adds SMMUv3 model to QEMU Multiple files, big ones, translate functionality is split across to accomodate SMMUv2 model, and to remove when common translation feature (if) becomes available. Patch 2: Adds SMMU build support Patch 3: Some devicetree function to add support for SMMU's multiple interrupt assignment with names Patch 4: Adds support in virt.c to create both SMMUv3 device and dts entries << optional patches >> Optional patches are posted for completeness or for those who wants to test. Patch 5: A simple PCI device which does DMA from 'src' to 'dst' given src_addr, dst_addr and size, and is used by unit test, uses pci_dma_read and pci_dma_write in a crude way but serves the purpose. Patch 6: Current libqos PCI helpers are x86 only, this addes a generic interface Patch 7: Unit tests for SMMU, - initializes SMMU device - initializes Test device - allocates page tables 1:1 mapping va == pa - allocates STE/CD accordingly for S1, S2, S1+S2 - initiates DMA via PCI test device - verifies transfered data Patch 8: Added ACPI IORT tables, was needed for internal project purpose, but posting here for anyone looking for testing ACPI on ARM platforms. (P.S: Linux side IORT patches are WIP) Repo: https://github.com/pmallappa/qemu/tree/develop To Test: $ make tests/smmuv3-test $ QTEST_QEMU_BINARY=aarch64-softmmu/qemu-system-aarch64 tests/smmuv3-test << expect lot of prints >> Any comments welcome..
