VkMemoryPropertyFlags(3)
|
|
========================
|
|
|
|
Name
|
|
----
|
|
VkMemoryPropertyFlags - Memory pool properties.
|
|
|
|
C Specification
|
|
---------------
|
|
|
|
include::../enums/VkMemoryPropertyFlagBits.txt[]
|
|
include::../flags/VkMemoryPropertyFlags.txt[]
|
|
|
|
Constants
|
|
---------
|
|
|
|
ename:VK_MEMORY_PROPERTY_DEVICE_ONLY::
|
|
Unless any other flag is used to enable other uses this constant
|
|
identifies memory that's only accessible by the device.
|
|
|
|
ename:VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT::
|
|
Identifies a memory pool that can be mapped into host memory address
|
|
space and thus is accessible by the host.
|
|
|
|
ename:VK_MEMORY_PROPERTY_HOST_NON_COHERENT_BIT::
|
|
Identifies a memory pool where accesses beteen the host and the
|
|
coherency domain are not conherent. Memory with this property needs
|
|
explicit use of flink:vkFlushMappedMemoryRanges after host writes to
|
|
this type of memory, and use of flink:vkInvalidateMappedMemoryRanges
|
|
before host reads from that memory.
|
|
|
|
ename:VK_MEMORY_PROPERTY_HOST_UNCACHED_BIT::
|
|
Identifies memory that is not cached by the host.
|
|
|
|
ename:VK_MEMORY_PROPERTY_LAZILY_ALLOCATED_BIT::
|
|
Identifies memory where an object's backing may be provided lazily
|
|
(when needed) by the implementation.
|
|
|
|
Description
|
|
-----------
|
|
|
|
These flags are used in the slink:VkMemoryAllocateInfo structure passed as parameter to flink:vkAllocateMemory
|
|
to define the properties of the memory pool the memory object should be allocated from.
|
|
|
|
Additionally, when querying the memory requirements of objects using
|
|
flink:vkGetBufferMemoryRequirements or flink:vkGetImageMemoryRequirements,
|
|
the ptext:memoryTypeBits member returned in the slink:VkMemoryRequirements
|
|
structure takes its values from these set of flags.
