Document error codes

1

It would be useful to have documentation about how different functions can fail, similar to how the Vulkan spec lists possible error codes for each operation. This should be possible...

Resizable VmaVirtualBlocks

1

Hello! We have an issue where we use a VmaVirtualBlock to suballocate a buffer for storing 3D model vertex and index data. At times, we run out of memory in...

Improve section "Recommended usage patterns" in docs

1

* Use [vmaCopyMemoryToAllocation](https://gpuopen-librariesandsdks.github.io/VulkanMemoryAllocator/html/group__group__alloc.html#ga11731ec58a3a43a22bb925e0780ef405) in section "Recommended usage patterns". * Try to embed the code from the actual test in the docs, so the code which is displayed there is actually...

Write a new test which covers readback using vmaCopyAllocationToMemory?

1

Since there is now a test which explains [vmaCopyMemoryToAllocation](https://gpuopen-librariesandsdks.github.io/VulkanMemoryAllocator/html/group__group__alloc.html#ga11731ec58a3a43a22bb925e0780ef405) in detail (see pr https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator/pull/474), it might be worth to write one more tests which deals with [vmaCopyAllocationToMemory](https://gpuopen-librariesandsdks.github.io/VulkanMemoryAllocator/html/group__group__alloc.html#gaac883dd38863944335071213b9ae8477). We could also...

Segfault on call to vmaCreateAllocator() when using c++11

7

This is on a raspberry pi 5, clean and up to date, VMA 3.2.1. I had a consistent segfault on line 12928 in the VmaAllocator_T constructor, called via 15075, and...

vkGetPhysicalDeviceMemoryProperties2KHR not found

4

I have a feeling that even on vulkan >= 1.1, sometimes vkGetPhysicalDeviceMemoryProperties2KHR is not found by the loader, unless the VK_KHR_get_physical_device_properties2 is enabled. maybe could be a good idea to...

VMA (pool) slower than a custom cache of buffers

1

I noticed than allocating and deallocating the same buffer in each of my compute iterations is very slow. I was expecting VMA to handle this efficiently because it has a...
