Class EXTDeviceMemoryReport

java.lang.Object

org.lwjgl.vulkan.EXTDeviceMemoryReport

public final class EXTDeviceMemoryReport
extends java.lang.Object

This device extension allows registration of device memory event callbacks upon device creation, so that applications or middleware can obtain detailed information about memory usage and how memory is associated with Vulkan objects. This extension exposes the actual underlying device memory usage, including allocations that are not normally visible to the application, such as memory consumed by CreateGraphicsPipelines. It is intended primarily for use by debug tooling rather than for production applications.

VkDeviceMemoryReportEventTypeEXT - Events that can occur on a device memory object

Description

• DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATE_EXT specifies this event corresponds to the allocation of an internal device memory object or a VkDeviceMemory.
• DEVICE_MEMORY_REPORT_EVENT_TYPE_FREE_EXT specifies this event corresponds to the deallocation of an internally-allocated device memory object or a VkDeviceMemory.
• DEVICE_MEMORY_REPORT_EVENT_TYPE_IMPORT_EXT specifies this event corresponds to the import of an external memory object.
• DEVICE_MEMORY_REPORT_EVENT_TYPE_UNIMPORT_EXT specifies this event is the release of an imported external memory object.
• DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATION_FAILED_EXT specifies this event corresponds to the failed allocation of an internal device memory object or a VkDeviceMemory.
