Description

This extension adds a priority value specified at memory allocation time. On some systems with both device-local and non-device-local memory heaps, the implementation may transparently move memory from one heap to another when a heap becomes full (for example, when the total memory used across all processes exceeds the size of the heap). In such a case, this priority value may be used to determine which allocations are more likely to remain in device-local memory.

New Enum Constants

  • VK_EXT_MEMORY_PRIORITY_EXTENSION_NAME

  • VK_EXT_MEMORY_PRIORITY_SPEC_VERSION

  • Extending VkStructureType:

    • VK_STRUCTURE_TYPE_MEMORY_PRIORITY_ALLOCATE_INFO_EXT

    • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MEMORY_PRIORITY_FEATURES_EXT
