|
|
vkInvalidateMappedMemoryRanges - Invalidate ranges of mapped memory objects.
|
|
|
|
C Specification
|
|
---------------
|
|
|
|
// refBegin vkInvalidateMappedMemoryRanges Invalidate ranges of mapped memory objects.
|
|
|
|
To invalidate ranges of non-coherent memory from the host caches, call:
|
|
|
|
include::../api/protos/vkInvalidateMappedMemoryRanges.txt[]
|
|
|
|
|
|
Parameters
|
|
----------
|
|
|
|
* pname:device is the logical device that owns the memory ranges.
|
|
* pname:memoryRangeCount is the length of the pname:pMemoryRanges array.
|
|
* pname:pMemoryRanges is a pointer to an array of
|
|
slink:VkMappedMemoryRange structures describing the memory ranges to
|
|
invalidate.
|
|
|
|
|
|
Description
|
|
-----------
|
|
|
|
fname:vkInvalidateMappedMemoryRanges must: be used to guarantee that device writes to
|
|
non-coherent memory are visible to the host. It must: be called after command buffers
|
|
that execute and flush (via memory barriers) the device writes have completed, and
|
|
before the host will read or write any of those locations. If a range of non-coherent
|
|
memory is written by the host and then invalidated without first being flushed, its
|
|
contents are undefined.
