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:
typedef struct VkDeviceGroupBindSparseInfo {
VkStructureType sType;
const void* pNext;
uint32_t resourceDeviceIndex;
uint32_t memoryDeviceIndex;
} VkDeviceGroupBindSparseInfo;
or the equivalent
typedef VkDeviceGroupBindSparseInfo VkDeviceGroupBindSparseInfoKHR;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to an extension-specific 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.
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.
