# hv_gic_config_set_redistributor_base(_:_:)

Sets the generic interrupt controller (GIC) redistributor region base address.

## Declaration

```swift
func hv_gic_config_set_redistributor_base(_ config: hv_gic_config_t, _ redistributor_base_address: hv_ipa_t) -> hv_return_t
```

## Parameters

- `config`: A GIC configuration object.
- `redistributor_base_address`: The guest’s physical address for the redistributor.

## Return Value

Return Value HV_SUCCESS on success; otherwise, an error code

## Discussion

Discussion Guest physical address for redistributor base aligned to byte value returned by hv_gic_get_redistributor_base_alignment(_:). The redistributor region contains redistributors for all vCPUs that the virtual machine supports.
