    Member documentation

    • sType – the type of this structure.
    • pNextNULL or a pointer to an extension-specific structure.
    • physicalDeviceCount – the number of physical devices in the group.
    • physicalDevices – an array of physical device handles representing all physical devices in the group. The first physicalDeviceCount 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 the deviceMask member of the VkMemoryAllocateFlagsInfo. If this is FALSE, then all device memory allocations are made across all physical devices in the group. If physicalDeviceCount is 1, then subsetAllocation must be FALSE.
