DRA821U: DRA821(j7200)是否支持SMMU?

Part Number: DRA821U


你们好:

在k3-j721e-main.dtsi的设备书中有关于smmu的描述:

smmu0: smmu@36600000 {
compatible = "arm,smmu-v3";
reg = <0x0 0x36600000 0x0 0x100000>;
power-domains = <&k3_pds 229 TI_SCI_PD_EXCLUSIVE>;
interrupt-parent = <&gic500>;
interrupts = <GIC_SPI 772 IRQ_TYPE_EDGE_RISING>,
<GIC_SPI 768 IRQ_TYPE_EDGE_RISING>;
interrupt-names = "eventq", "gerror";
#iommu-cells = <1>;
dma-coherent;
};

但是在j7200的设备树中,没有看到关于smmu的描述,是j7200不支持smmu吗?在虚拟化环境下,j7200如何实现设备直通?
