C Specification
If the pNext chain includes a VkMemoryPriorityAllocateInfoEXT
structure, then that structure includes a priority for the memory.
The VkMemoryPriorityAllocateInfoEXT structure is defined as:
typedef struct VkMemoryPriorityAllocateInfoEXT {
VkStructureType sType;
const void* pNext;
float priority;
} VkMemoryPriorityAllocateInfoEXT;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure. -
priorityis a floating-point value between0and1, indicating the priority of the allocation relative to other memory allocations. Larger values are higher priority. The granularity of the priorities is implementation-dependent.
Description
Memory allocations with higher priority may be more likely to stay in device-local memory when the system is under memory pressure.
If this structure is not included, it is as if the priority value were
0.5.
