VkDeviceGroupBindSparseInfo

If the pNext chain of VkBindSparseInfo includes a VkDeviceGroupBindSparseInfo structure, then that structure includes device indices specifying which instance of the resources and memory are bound.

The VkDeviceGroupBindSparseInfo structure is defined as:

typedef struct VkDeviceGroupBindSparseInfo {
    VkStructureType sType;
    const void* pNext;
    uint32_t resourceDeviceIndex;
    uint32_t memoryDeviceIndex;
} VkDeviceGroupBindSparseInfo;

or the equivalent

typedef VkDeviceGroupBindSparseInfo VkDeviceGroupBindSparseInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• resourceDeviceIndex is a device index indicating which instance of the resource is bound.
• memoryDeviceIndex is a device index indicating which instance of the memory the resource instance is bound to.

These device indices apply to all buffer and image memory binds included in the batch pointing to this structure. The semaphore waits and signals for the batch are executed only by the physical device specified by the resourceDeviceIndex.

If this structure is not present, resourceDeviceIndex and memoryDeviceIndex are assumed to be zero.
