GRLIB GRIOMMU Model

The GRIOMMU model is available in the GrIoMmu plugin.

Loading the Plugin

import GrIoMmu

Configuration

The model should be attached in two directions:

Firstly, IO-devices need to have their memory access interface references routed through the IOMMU. To do this, connect the memory access iface ref in the device to IOMMUAccessIface in the IOMMU.

Secondly, the IOMMU needs to get access to the device’s AMBA PNP info. The info is used to populate the MasterConfig registers. To set the PNP info, attach it to the devicePnp array.

The IOMMUAccessIface and devicePnp array assumes that the same device indexes are used. Not connecting devices the correct way is undefined behaviour.

Connecting the GRIOMMU
// Connect command
connect a=iommu.devicePnp[0] b=device:ApbIface (1)
connect a=device.mem b=iommu:IOMMUAccessIface[0] (2)

// Or with assigmment syntax
iommu.devicePnp[0] = device:ApbIface (1)
device.mem = iommu:IOMMUAccessIface[0] (2)
1 Index should match index on next line.
2 Index should match index on previous line.

Limitations

  • Read and write combining is not simulated

  • Bus select is ignored, only one memory space is used for memory and processor.

  • APV and TLB caches are not implemented at the moment.

  • Flushes are instantaneous. This means that the FLI and FCI will only result in one actual interrupt being raised.
