Classified GPU generation

mmio_base: u64

BAR0 MMIO base address

mmio_size: u64

BAR0 MMIO region size

vram_size: u64

VRAM size in bytes (from BAR or discovery)

vram_base: u64

Implementations

impl AmdGpuDevice

pub fn classify_generation(device_id: u16) -> AmdGeneration

Classify GPU generation from PCI device ID.

Device ID ranges are derived from the upstream amdgpu driver chip identification tables.

pub fn has_raytracing(&self) -> bool

Return true if this GPU supports hardware raytracing (RDNA2+).
