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.

Documentation
data PhysicalDeviceMemoryPriorityFeaturesEXT Source #
VkPhysicalDeviceMemoryPriorityFeaturesEXT - Structure describing memory priority features that can be supported by an implementation
Members
The members of the PhysicalDeviceMemoryPriorityFeaturesEXT
structure
describe the following features:
Description
If the PhysicalDeviceMemoryPriorityFeaturesEXT
structure is included
in the pNext
chain of
PhysicalDeviceFeatures2
,
it is filled with values indicating whether the feature is supported.
PhysicalDeviceMemoryPriorityFeaturesEXT
can also be included in the
pNext
chain of DeviceCreateInfo
to enable
features.

Instances
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
.
