This extension provides new entry points to query memory requirements of
|
|
images and buffers in a way that can be easily extended by other extensions,
|
|
without introducing any further entry points.
|
|
The Vulkan 1.0 slink:VkMemoryRequirements and
|
|
slink:VkSparseImageMemoryRequirements structures do not include a
|
|
pname:sType/pname:pNext, this extension wraps them in new structures with
|
|
pname:sType/pname:pNext so an application can query a chain of memory
|
|
requirements structures by constructing the chain and letting the
|
|
implementation fill them in.
|
|
A new command is added for each ftext:vkGet*MemoryRequrements command in
|
|
core Vulkan 1.0.
|
|

=== Promotion to Vulkan 1.1
|
|
|
|
All functionality in this extension is included in core Vulkan 1.1, with the
|
|
KHR suffix omitted.
|
|
The original type, enum and command names are still available as aliases of
|
|
the core functionality.
|
|
|
|
=== Issues
