Channel offer parameters.

Fields

interface_name: String

An informational string describing the channel type.

instance_id: Guid

The unique instance ID for the channel.

interface_id: Guid

The interface ID describing the type of channel.

mmio_megabytes: u16

The amount of MMIO space needed by the channel, in megabytes.

mmio_megabytes_optional: u16

The amount of optional MMIO space used by the channel, in megabytes.

channel_type: ChannelType

The channel’s type.

subchannel_index: u16

The subchannel index. Index 0 indicates a primary (normal channel).

mnf_interrupt_latency: Option<Duration>

Indicates whether the channel’s interrupts should use monitor pages, and the interrupt latency if it’s enabled.

offer_order: Option<u32>

The order in which channels with the same interface will be offered to the guest (optional).

allow_confidential_external_memory: bool

Indicates whether the channel supports using encrypted memory for any external GPADLs and GPA direct ranges. This is only used when hardware isolation is in use.
