Enum SessionGpuId 

pub enum SessionGpuId {
    Drm {
        render_minor: u32,
    },
    Luid(u64),
    Metal {
        registry_id: u64,
    },
    Pci {
        vendor_id: u32,
        device_id: u32,
    },
    Default,
}

The backend’s handle for an adapter in this session.

Variants

Drm

A DRM render node (Linux). The node number is assigned per boot and is not a hardware id.

Fields

render_minor: u32

The node’s minor number: renderD<minor>.

Luid(u64)

A DXGI adapter LUID (Windows), packed from Luid.HighPart/LowPart. It lasts for the adapter’s lifetime and changes on reboot, driver upgrade, or device disable/enable.

Metal

A Metal registry id (macOS) — an IOKit registry entry id, valid only until reboot.

Fields

registry_id: u64

The IOKit registry id.

Pci

The PCI pair, where the backend has no per-boot handle; identical cards share it.

Fields

vendor_id: u32

The PCI vendor id.

device_id: u32

The PCI device id.

Default

A platform with one GPU, or a backend whose enumeration cannot name one.
