C Specification
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:
// Provided by VK_VERSION_1_1
typedef struct VkDeviceGroupBindSparseInfo {
VkStructureType sType;
const void* pNext;
uint32_t resourceDeviceIndex;
uint32_t memoryDeviceIndex;
} VkDeviceGroupBindSparseInfo;
or the equivalent
// Provided by VK_KHR_device_group
typedef VkDeviceGroupBindSparseInfo VkDeviceGroupBindSparseInfoKHR;
Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
resourceDeviceIndexis a device index indicating which instance of the resource is bound. -
memoryDeviceIndexis a device index indicating which instance of the memory the resource instance is bound to.
Description
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.
