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.

Synopsis

data PhysicalDeviceMemoryPriorityFeaturesEXT Source #

VkPhysicalDeviceMemoryPriorityFeaturesEXT - Structure describing memory priority features that can be supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceMemoryPriorityFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceMemoryPriorityFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

data MemoryPriorityAllocateInfoEXT Source #

VkMemoryPriorityAllocateInfoEXT - Specify a memory allocation priority

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.

Fields

  • priority :: Float

    priority is a floating-point value between 0 and 1, indicating the priority of the allocation relative to other memory allocations. Larger values are higher priority. The granularity of the priorities is implementation-dependent.

    priority must be between 0 and 1, inclusive
