Enum SmmuSsidSize 

pub enum SmmuSsidSize {
    Auto,
    Fixed(u8),
}

SubstreamID width (SSIDSIZE) policy for an emulated SMMUv3.

Variants

Auto

Disable substreams in software mode; under acceleration, adopt the host’s width before device start freezes the capabilities.

Fixed(u8)

Use a fixed width in bits (0..=20). Zero disables substreams. Under acceleration, this cannot exceed the host’s width.
