VkPhysicalDeviceVulkan11Properties

The VkPhysicalDeviceVulkan11Properties structure is defined as:

typedef struct VkPhysicalDeviceVulkan11Properties {
    VkStructureType sType;
    void* pNext;
    uint8_t deviceUUID[VK_UUID_SIZE];
    uint8_t driverUUID[VK_UUID_SIZE];
    uint8_t deviceLUID[VK_LUID_SIZE];
    uint32_t deviceNodeMask;
    VkBool32 deviceLUIDValid;
    uint32_t subgroupSize;
    VkShaderStageFlags subgroupSupportedStages;
    VkSubgroupFeatureFlags subgroupSupportedOperations;
    VkBool32 subgroupQuadOperationsInAllStages;
    VkPointClippingBehavior pointClippingBehavior;
    uint32_t maxMultiviewViewCount;
    uint32_t maxMultiviewInstanceIndex;
    VkBool32 protectedNoFault;
    uint32_t maxPerSetDescriptors;
    VkDeviceSize maxMemoryAllocationSize;
} VkPhysicalDeviceVulkan11Properties;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• deviceUUID is an array of VK_UUID_SIZE uint8_t values representing a universally unique identifier for the device.
• driverUUID is an array of VK_UUID_SIZE uint8_t values representing a universally unique identifier for the driver build in use by the device.
• deviceLUID is an array of VK_LUID_SIZE uint8_t values representing a locally unique identifier for the device.
• deviceNodeMask is a uint32_t bitfield identifying the node within a linked device adapter corresponding to the device.
• deviceLUIDValid is a boolean value that will be VK_TRUE if deviceLUID contains a valid LUID and deviceNodeMask contains a valid node mask, and VK_FALSE if they do not.
• subgroupSize is the default number of invocations in each subgroup. subgroupSize is at least 1 if any of the physical device’s queues support VK_QUEUE_GRAPHICS_BIT or VK_QUEUE_COMPUTE_BIT. subgroupSize is a power-of-two.
• subgroupSupportedStages is a bitfield of VkShaderStageFlagBits describing the shader stages that group operations with subgroup scope are supported in. subgroupSupportedStages will have the VK_SHADER_STAGE_COMPUTE_BIT bit set if any of the physical device’s queues support VK_QUEUE_COMPUTE_BIT.
• subgroupSupportedOperations is a bitmask of VkSubgroupFeatureFlagBits specifying the sets of group operations with subgroup scope supported on this device. subgroupSupportedOperations 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.
• subgroupQuadOperationsInAllStages is a boolean specifying whether quad group operations are available in all stages, or are restricted to fragment and compute stages.
• pointClippingBehavior is a VkPointClippingBehavior value specifying the point clipping behavior supported by the implementation.
• maxMultiviewViewCount is one greater than the maximum view index that can be used in a subpass.
• maxMultiviewInstanceIndex is 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.
• protectedNoFault 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 VK_TRUE, such writes will be discarded or have undefined: values written, reads and queries will return undefined: values. If this limit is VK_FALSE, applications must not perform these operations. See xref::name::memory-protected-access-rules for more information.
• maxPerSetDescriptors is 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.
• maxMemoryAllocationSize is the maximum size of a memory allocation that can be created, even if there is more space available in the heap.

If the VkPhysicalDeviceVulkan11Properties structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

These properties correspond to Vulkan 1.1 functionality.

The members of VkPhysicalDeviceVulkan11Properties have the same values as the corresponding members of VkPhysicalDeviceIDProperties, VkPhysicalDeviceSubgroupProperties, VkPhysicalDevicePointClippingProperties, VkPhysicalDeviceMultiviewProperties, VkPhysicalDeviceProtectedMemoryProperties, and VkPhysicalDeviceMaintenance3Properties.
