A first implementation of this IOMMU is available on the Rockchip RK3588 SoC. Rockchip provides a driver for this hardware in their 6.1 kernel branch: https://github.com/rockchip-linux/kernel/blob/develop-6.1/drivers/iommu/rockchip-iommu-av1d.c This series includes: - a new binding for the Verisilicon IOMMU - a basic driver implementation - DT updates for RK3588 The driver was forward-ported from Rockchip’s 6.1 implementation, the prefix was renamed to vsi for generality, and several fixes were applied. AV1 decoding was tested using the stateless VPU driver and Fluster. The test results show a score of 205/239, which confirms that no regressions were introduced by this series. Feedback and testing welcome. changes in version 2: - Add a compatible "rockchip,rk3588-av1-iommu" - Fix clock-names in binding - Remove "vsi_mmu" label in binding example. - Rework driver probe function - Remove double flush - Rework driver internal structures and avoid allocate in xlate function. - Do not touch to VPU driver anymore (path removed) - Add a patch to enable the driver in arm64 defconfig Thanks, Benjamin Benjamin Gaignard (5): dt-bindings: vendor-prefixes: Add Verisilicon dt-bindings: iommu: verisilicon: Add binding for VSI IOMMU iommu: Add verisilicon IOMMU driver arm64: dts: rockchip: Add verisilicon IOMMU node on RK3588 arm64: defconfig: enable Verisilicon IOMMU .../bindings/iommu/verisilicon,iommu.yaml | 72 ++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + arch/arm64/boot/dts/rockchip/rk3588-base.dtsi | 11 + arch/arm64/configs/defconfig | 1 + drivers/iommu/Kconfig | 12 + drivers/iommu/Makefile | 1 + drivers/iommu/vsi-iommu.c | 841 ++++++++++++++++++ 7 files changed, 940 insertions(+) create mode 100644 Documentation/devicetree/bindings/iommu/verisilicon,iommu.yaml create mode 100644 drivers/iommu/vsi-iommu.c -- 2.43.0
