# hv_gic_config_set_redistributor_base(_:_:)

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

```
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

[`HV_SUCCESS`](/documentation/Hypervisor/HV_SUCCESS) on success; otherwise, an error code

## Discussion

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