From: Nikhil Devshatwar <[email protected]> This series adds support for TI PVU as an iommu unit. PVU is a 2nd stage only IOMMU which provides realtime address translation.
J721e has 3 instances of PVU and all the DMA traffic can be routed via PVU when running inside a virtual machine. Changes from v1: * New patch1 for avoiding warning when unmap is called from cell_destroy * Split the patch affecting amd fields into separate one * SMMU fixes are sent in another series Nikhil Devshatwar (5): core: Update cell_state while destroying the cell configs: Introduce tipvu IOMMU specific fields in platform_data arm64: ti-pvu: Add support for ti-pvu iommu unit configs: arm64: k3-j721e-evm: Add PVU IOMMU devices in platform_data configs: arm64: k3-j721e-evm: Add stream ids for devices behind IOMMU configs/arm64/k3-j721e-evm-linux-demo.c | 7 + configs/arm64/k3-j721e-evm.c | 36 ++ hypervisor/arch/arm-common/include/asm/cell.h | 7 + .../arch/arm-common/include/asm/iommu.h | 1 + .../arch/arm-common/include/asm/ti-pvu.h | 129 ++++ hypervisor/arch/arm-common/iommu.c | 5 +- hypervisor/arch/arm64/Kbuild | 3 +- hypervisor/arch/arm64/ti-pvu.c | 581 ++++++++++++++++++ hypervisor/control.c | 2 + include/jailhouse/cell-config.h | 17 +- 10 files changed, 781 insertions(+), 7 deletions(-) create mode 100644 hypervisor/arch/arm-common/include/asm/ti-pvu.h create mode 100644 hypervisor/arch/arm64/ti-pvu.c -- 2.17.1 -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
