Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure.
Description
-
deviceUUID
is an array ofVK_UUID_SIZE
uint8_t
values representing a universally unique identifier for the device. -
driverUUID
is an array ofVK_UUID_SIZE
uint8_t
values representing a universally unique identifier for the driver build in use by the device. -
deviceLUID
is an array ofVK_LUID_SIZE
uint8_t
values representing a locally unique identifier for the device. -
deviceNodeMask
is auint32_t
bitfield identifying the node within a linked device adapter corresponding to the device. -
deviceLUIDValid
is a boolean value that will beVK_TRUE
ifdeviceLUID
contains a valid LUID anddeviceNodeMask
contains a valid node mask, andVK_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 supportVK_QUEUE_GRAPHICS_BIT
orVK_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 theVK_SHADER_STAGE_COMPUTE_BIT
bit set if any of the physical device’s queues supportVK_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 theVK_SUBGROUP_FEATURE_BASIC_BIT
bit set if any of the physical device’s queues supportVK_QUEUE_GRAPHICS_BIT
orVK_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 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. -
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 VkMemoryAllocateInfo::allocationSize
is larger the errorVK_ERROR_OUT_OF_DEVICE_MEMORY
may 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.
