C Specification
The VkPhysicalDeviceGroupProperties
structure is defined as:
// Provided by VK_VERSION_1_1
typedef struct VkPhysicalDeviceGroupProperties {
VkStructureType sType;
void* pNext;
uint32_t physicalDeviceCount;
VkPhysicalDevice physicalDevices[VK_MAX_DEVICE_GROUP_SIZE];
VkBool32 subsetAllocation;
} VkPhysicalDeviceGroupProperties;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
physicalDeviceCount
is the number of physical devices in the group. -
physicalDevices
is an array ofVK_MAX_DEVICE_GROUP_SIZE
VkPhysicalDevice handles representing all physical devices in the group. The firstphysicalDeviceCount
elements of the array will be valid. -
subsetAllocation
specifies whether logical devices created from the group support allocating device memory on a subset of devices, via thedeviceMask
member of the VkMemoryAllocateFlagsInfo. If this isVK_FALSE
, then all device memory allocations are made across all physical devices in the group. IfphysicalDeviceCount
is1
, thensubsetAllocation
must beVK_FALSE
.
