Description of Vulkan 1.1 properties.

See VkPhysicalDeviceVulkan11Properties manual page.

Fields

device_uuid: [u8; 16]

An array of VK_UUID_SIZE u8 values representing a universally unique identifier for the device

driver_uuid: [u8; 16]

An array of VK_UUID_SIZE u8 values representing a universally unique identifier for the driver build in use by the device.

device_luid: [u8; 8]

An array of VK_LUID_SIZE u8 values representing a locally unique identifier for the device

device_node_mask: u32

A u32 bitfield identifying the node within a linked device adapter corresponding to the device.

device_luid_valid: bool

A bool value that will be true if device_luid contains a valid LUID and device_node_mask contains a valid node mask, and false if they do not.

subgroup_size: u32

The default number of invocations in each subgroup. subgroup_size is at least 1 if any of the physical device’s queues support VK_QUEUE_GRAPHICS_BIT or VK_QUEUE_COMPUTE_BIT. subgroup_size is a power-of-two.

subgroup_supported_stages: ShaderStageFlags

A bitfield of vk::ShaderStageFlagBits describing the shader stages that group operations with subgroup scope are supported in. subgroup_supported_stages will have the VK_SHADER_STAGE_COMPUTE_BIT bit set if any of the physical device’s queues support VK_QUEUE_COMPUTE_BIT.

subgroup_supported_operations: SubgroupFeatureFlags

A bitmask of vk::SubgroupFeatureFlagBits specifying the sets of group operations with subgroup scope supported on this device. subgroup_supported_operations will have the VK_SUBGROUP_FEATURE_BASIC_BIT bit set if any of the physical device’s queues support VK_QUEUE_GRAPHICS_BIT or VK_QUEUE_COMPUTE_BIT.

subgroup_quad_operations_in_all_stages: bool

A bool specifying whether quad group operations are available in all stages, or are restricted to fragment and compute stages.

point_clipping_behavior: PointClippingBehavior

A vk::PointClippingBehavior value specifying the point clipping behavior supported by the implementation.

max_multiview_view_count: u32

max_multiview_view_count is one greater than the maximum view index that can be used in a subpass.

max_multiview_instance_index: u32

The maximum valid value of instance index allowed to be generated by a drawing command recorded within a subpass of a multiview render pass instance.

protected_no_fault: bool

Specifies how an implementation behaves when an application attempts to write to unprotected memory in a protected queue operation, read from protected memory in an unprotected queue operation, or perform a query in a protected queue operation.

If this limit is true, such writes will be discarded or have undefined values written, reads and queries will return undefined values.

If this limit is false, applications must not perform these operations.

See memory-protected-access-rules for more information.

max_per_set_descriptors: u32

A maximum number of descriptors (summed over all descriptor types) in a single descriptor set that is guaranteed to satisfy any implementation-dependent constraints on the size of a descriptor set itself.

Applications can query whether a descriptor set that goes beyond this limit is supported using vkGetDescriptorSetLayoutSupport.

max_memory_allocation_size: DeviceSize

The maximum size of a memory allocation that can be created, even if there is more space available in the heap.

Trait Implementations
