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.
