Adapter Properties

Memory Heaps

wgpu::FeatureName::AdapterPropertiesMemoryHeaps allows querying memory heap information from the adapter.

wgpu::AdapterPropertiesMemoryHeaps may be chained on wgpu::AdapterInfo in a call to wgpu::Adapter::GetInfo or wgpu::Device::GetAdapterInfo in order to query information about the memory heaps on the adapter. The implementation will write out the number of memory heaps and information about each heap.

If wgpu::FeatureName::AdapterPropertiesMemoryHeaps is not available, the struct will not be populated.

Adds wgpu::HeapProperty which is a bitmask describing the type of memory a heap is. Valid bits:

• DeviceLocal
• HostVisible
• HostCoherent
• HostUncached
• HostCached

Note that both HostUncached and HostCached may be set if a heap can allocate pages with either cache property.

Adds wgpu::MemoryHeapInfo which is a struct describing a memory heap.

struct MemoryHeapInfo {
    HeapProperty properties;
    uint64_t size;
};

wgpu::MemoryHeapInfo::size is the size that should be allocated out of this heap. Allocating more than this may result in poor performance or may deterministically run out of memory.

DRM properties

wgpu::FeatureName:AdapterPropertiesDRM, currently only available on Vulkan (but could be added on OpenGL / ES), allows querying Linux DRM information about the adapter.

wgpu::AdapterPropertiesDRM may be chained on wgpu::AdapterInfo in a call to wgpu::Adapter::GetInfo or wgpu::Device::GetAdapterInfo in order to query DRM information on the adapter.

D3D

wgpu::FeatureName::AdapterPropertiesD3D allows querying D3D information from the adapter.

wgpu::AdapterPropertiesD3D may be chained on wgpu::AdapterInfo in a call to wgpu::Adapter::GetInfo or wgpu::Device::GetAdapterInfo in order to query D3D information on the adapter.

Adds wgpu::AdapterPropertiesD3D which is a struct describing the D3D adapter.

struct AdapterPropertiesD3D {
    uint32_t shaderModel;  // The D3D shader model
};

Vulkan

wgpu::FeatureName::AdapterPropertiesVk allows querying Vulkan information from the adapter.

wgpu::AdapterPropertiesVk may be chained on wgpu::AdapterInfo in a call to wgpu::Adapter::GetInfo or wgpu::Device::GetAdapterInfo in order to query Vulkan information on the adapter.

Adds wgpu::AdapterPropertiesVk which is a struct describing the Vulkan adapter.

struct AdapterPropertiesVk {
    uint32_t driverVersion;  // The Vulkan driver version
};

WebGPU

wgpu::FeatureName::AdapterPropertiesWGPU allows querying inner backend information of the WebGPUBackend from the adapter.

wgpu::AdapterPropertiesWGPU may be chained on wgpu::AdapterInfo in a call to wgpu::Adapter::GetInfo or wgpu::Device::GetAdapterInfo in order to query WebGPU backend information on the adapter.

Adds wgpu::AdapterPropertiesWGPU which is a struct describing the WebGPU adapter.

struct AdapterPropertiesWGPU {
    wgpu::BackendType backendType;  // The inner backend type
};
