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;
or the equivalent
// Provided by VK_KHR_device_group_creation
typedef VkPhysicalDeviceGroupProperties VkPhysicalDeviceGroupPropertiesKHR;
Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
physicalDeviceCountis the number of physical devices in the group. -
physicalDevicesis an array ofVK_MAX_DEVICE_GROUP_SIZEVkPhysicalDevice handles representing all physical devices in the group. The firstphysicalDeviceCountelements of the array will be valid. -
subsetAllocationspecifies whether logical devices created from the group support allocating device memory on a subset of devices, via thedeviceMaskmember of the VkMemoryAllocateFlagsInfo. If this isVK_FALSE, then all device memory allocations are made across all physical devices in the group. IfphysicalDeviceCountis1, thensubsetAllocationmust beVK_FALSE.
