## C Specification

The VkPhysicalDeviceVulkan11Properties structure is defined as:

// Provided by VK_VERSION_1_2
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];
VkBool32                   deviceLUIDValid;
uint32_t                   subgroupSize;
VkSubgroupFeatureFlags     subgroupSupportedOperations;
VkPointClippingBehavior    pointClippingBehavior;
uint32_t                   maxMultiviewViewCount;
uint32_t                   maxMultiviewInstanceIndex;
VkBool32                   protectedNoFault;

VkDeviceSize               maxMemoryAllocationSize;
} VkPhysicalDeviceVulkan11Properties;

## Members

• sType is the type of this structure.

• pNext is NULL or a pointer to a structure extending this structure.

## Description

• 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 the behavior of the implementation when protected memory access rules are broken. If protectedNoFault is VK_TRUE, breaking those rules will not result in process termination or device loss.

• 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.
