device_id: u16

PCI device ID

generation: IntelGeneration

Classified GPU generation

mmio_base: u64

BAR0 MMIO base address

mmio_size: u64

BAR0 MMIO region size

gtt_size: u64

GTT aperture size (detected during init)

Implementations

impl I915Device

pub fn classify_generation(device_id: u16) -> IntelGeneration

Classify GPU generation from PCI device ID.

Device ID ranges are derived from the upstream i915 and xe driver source tables.

pub fn is_discrete(&self) -> bool

Return true if this is a discrete GPU (Arc).
