Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure.
Description
-
deviceUUIDis an array ofVK_UUID_SIZEuint8_tvalues representing a universally unique identifier for the device. -
driverUUIDis an array ofVK_UUID_SIZEuint8_tvalues representing a universally unique identifier for the driver build in use by the device. -
deviceLUIDis an array ofVK_LUID_SIZEuint8_tvalues representing a locally unique identifier for the device. -
deviceNodeMaskis auint32_tbitfield identifying the node within a linked device adapter corresponding to the device. -
deviceLUIDValidis a boolean value that will beVK_TRUEifdeviceLUIDcontains a valid LUID anddeviceNodeMaskcontains a valid node mask, andVK_FALSEif they do not.
-
subgroupSizeis the default number of invocations in each subgroup.subgroupSizeis at least 1 if any of the physical device’s queues supportVK_QUEUE_GRAPHICS_BITorVK_QUEUE_COMPUTE_BIT.subgroupSizeis a power-of-two. -
subgroupSupportedStagesis a bitfield of VkShaderStageFlagBits describing the shader stages that group operations with subgroup scope are supported in.subgroupSupportedStageswill have theVK_SHADER_STAGE_COMPUTE_BITbit set if any of the physical device’s queues supportVK_QUEUE_COMPUTE_BIT. -
subgroupSupportedOperationsis a bitmask of VkSubgroupFeatureFlagBits specifying the sets of group operations with subgroup scope supported on this device.subgroupSupportedOperationswill have theVK_SUBGROUP_FEATURE_BASIC_BITbit set if any of the physical device’s queues supportVK_QUEUE_GRAPHICS_BITorVK_QUEUE_COMPUTE_BIT. -
subgroupQuadOperationsInAllStagesis a boolean specifying whether quad group operations are available in all stages, or are restricted to fragment and compute stages. -
pointClippingBehavioris a VkPointClippingBehavior value specifying the point clipping behavior supported by the implementation. -
maxMultiviewViewCountis one greater than the maximum view index that can be used in a subpass. -
maxMultiviewInstanceIndexis 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. -
protectedNoFaultspecifies 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 isVK_TRUE, such writes will be discarded or have undefined values written, reads and queries will return undefined values. If this limit isVK_FALSE, applications must not perform these operations. See [memory-protected-access-rules] for more information. -
maxPerSetDescriptorsis 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. -
maxMemoryAllocationSizeis the maximum size of a memory allocation that can be created, even if there is more space available in the heap. If VkMemoryAllocateInfo::allocationSizeis larger the errorVK_ERROR_OUT_OF_DEVICE_MEMORYmay be returned.
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.
