Custom memory pools</h1>
<p>If you allocate from custom memory pool, all the ways of specifying memory requirements described above are not applicable and the aforementioned members of <a class="el" href="struct_vma_allocation_create_info.html">VmaAllocationCreateInfo</a> structure are ignored. Memory type is selected explicitly when creating the pool and then used to make all the allocations from that pool. For further details, see <a class="el" href="custom_memory_pools.html">Custom memory pools</a>.</p>

Features not supported</h1>
<p>Features deliberately excluded from the scope of this library:</p>
<ul>
<li>Data transfer. Uploading (streaming) and downloading data of buffers and images between CPU and GPU memory and related synchronization is responsibility of the user. Defining some "texture" object that would automatically stream its data from a staging copy in CPU memory to GPU memory would rather be a feature of another, higher-level library implemented on top of VMA.</li>
<li>Allocations for imported/exported external memory. They tend to require explicit memory type index and dedicated allocation anyway, so they don't interact with main features of this library. Such special purpose allocations should be made manually, using <code>vkCreateBuffer()</code> and <code>vkAllocateMemory()</code>.</li>
<li>Sub-allocation of parts of one large buffer. Although recommended as a good practice, it is the user's responsibility to implement such logic on top of VMA.</li>
<li>Recreation of buffers and images. Although the library has functions for buffer and image creation (<a class="el" href="vk__mem__alloc_8h.html#ac72ee55598617e8eecca384e746bab51">vmaCreateBuffer()</a>, <a class="el" href="vk__mem__alloc_8h.html#a02a94f25679275851a53e82eacbcfc73" title="Function similar to vmaCreateBuffer().">vmaCreateImage()</a>), you need to recreate these objects yourself after defragmentation. That's because the big structures <code>VkBufferCreateInfo</code>, <code>VkImageCreateInfo</code> are not stored in <a class="el" href="struct_vma_allocation.html" title="Represents single memory allocation.">VmaAllocation</a> object.</li>
<li>Handling CPU memory allocation failures. When dynamically creating small C++ objects in CPU memory (not Vulkan memory), allocation failures are not checked and handled gracefully, because that would complicate code significantly and is usually not needed in desktop PC applications anyway. Success of an allocation is just checked with an assert.</li>
<li>Code free of any compiler warnings. Maintaining the library to compile and work correctly on so many different platforms is hard enough. Being free of any warnings, on any version of any compiler, is simply not feasible.</li>
<li>This is a C++ library with C interface. Bindings or ports to any other programming languages are welcomed as external projects and are not going to be included into this repository. </li>

Being free of any warnings, on any version of any compiler, is simply not feasible. There are many preprocessor macros that make some variables unused, function parameters unreferenced, or conditional expressions constant in some configurations. The code of this library should not be bigger or more complicated just to silence these warnings. It is recommended to disable such warnings instead.</li>

<ul>
<li>When operating system is Windows 7 or 8.x (Windows 10 is not affected because it uses WDDM2), device is discrete AMD GPU, and memory type is the special 256 MiB pool of <code>DEVICE_LOCAL + HOST_VISIBLE</code> memory (selected when you use <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305cca9066b52c5a7079bb74a69aaf8b92ff67">VMA_MEMORY_USAGE_CPU_TO_GPU</a>), then whenever a memory block allocated from this memory type stays mapped for the time of any call to <code>vkQueueSubmit()</code> or <code>vkQueuePresentKHR()</code>, this block is migrated by WDDM to system RAM, which degrades performance. It doesn't matter if that particular memory block is actually used by the command buffer being submitted.</li>

</div><!-- fragment --><p>Remember that using resources that alias in memory requires proper synchronization. You need to issue a memory barrier to make sure commands that use <code>img1</code> and <code>img2</code> don't overlap on GPU timeline. You also need to treat a resource after aliasing as uninitialized - containing garbage data. For example, if you use <code>img1</code> and then want to use <code>img2</code>, you need to issue an image memory barrier for <code>img2</code> with <code>oldLayout</code> = <code>VK_IMAGE_LAYOUT_UNDEFINED</code>.</p>

Features deliberately excluded from the scope of this library:
- Data transfer. Uploading (streaming) and downloading data of buffers and images
- **Data transfer.** Uploading (streaming) and downloading data of buffers and images
between CPU and GPU memory and related synchronization is responsibility of the user.
Defining some "texture" object that would automatically stream its data from a
staging copy in CPU memory to GPU memory would rather be a feature of another,
higher-level library implemented on top of VMA.
- Allocations for imported/exported external memory. They tend to require
explicit memory type index and dedicated allocation anyway, so they don't
interact with main features of this library. Such special purpose allocations
should be made manually, using `vkCreateBuffer()` and `vkAllocateMemory()`.
- Sub-allocation of parts of one large buffer. Although recommended as a good practice,
it is the user's responsibility to implement such logic on top of VMA.
- Recreation of buffers and images. Although the library has functions for
- **Recreation of buffers and images.** Although the library has functions for
buffer and image creation (vmaCreateBuffer(), vmaCreateImage()), you need to
recreate these objects yourself after defragmentation. That's because the big
structures `VkBufferCreateInfo`, `VkImageCreateInfo` are not stored in
#VmaAllocation object.
- Handling CPU memory allocation failures. When dynamically creating small C++
- **Handling CPU memory allocation failures.** When dynamically creating small C++
objects in CPU memory (not Vulkan memory), allocation failures are not checked
and handled gracefully, because that would complicate code significantly and
is usually not needed in desktop PC applications anyway.
Success of an allocation is just checked with an assert.
- Code free of any compiler warnings. Maintaining the library to compile and
- **Code free of any compiler warnings.** Maintaining the library to compile and
work correctly on so many different platforms is hard enough. Being free of
any warnings, on any version of any compiler, is simply not feasible.
- This is a C++ library with C interface.
Bindings or ports to any other programming languages are welcomed as external projects and
There are many preprocessor macros that make some variables unused, function parameters unreferenced,
or conditional expressions constant in some configurations.
The code of this library should not be bigger or more complicated just to silence these warnings.
It is recommended to disable such warnings instead.
- This is a C++ library with C interface. **Bindings or ports to any other programming languages** are welcome as external projects but
are not going to be included into this repository.
