The VkExternalMemoryImageCreateInfo structure is defined as: // Provided by VK_VERSION_1_1 typedef struct VkExternalMemoryImageCreateInfo { VkStructureType sType; const void* pNext; VkExternalMemoryHandleTypeFlags handleTypes; } VkExternalMemoryImageCreateInfo; or the equivalent.
1) Do applications need to call CloseHandle() on the values returned from vkGetMemoryWin32HandleKHR when handleType is VK_ EXTERNAL _MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_KHR? RESOLVED : Yes, unless it is passed back in to another driver instance to import the object.

Creates a VkExternalMemoryProperties instance at the current position of the specified ByteBuffer container. Changes to the buffer’s content will be visible to the struct instance and vice versa. The created instance holds a strong reference to the container object.

Here again a secondary VkExportMemoryAllocateInfo struct was necessary in order to set the VK_ EXTERNAL _MEMORY_HANDLE_TYPE_OPAQUE_FD_BIT to the VkMemoryAllocateInfo struct.. Step 2: Creating an OpenGL texture from the Vulkan allocated image (Interoperability) First of all, I had to import the Vulkan memory in OpenGL, in other words create a GL memory object from a Vulkan.
The reason why NV card (i assume you’re using NV card) works is NV driver does not set flag VK_ EXTERNAL _MEMORY_FEATURE_DEDICATED_ONLY_BIT_KHR in externalMemoryProperties.externalMemoryFeatures, then your application on NV card would go different path using vkGetImageMemoryRequirements() and vkBindImageMemory(), however, if on AMD card,.
11/7/2017 · VK_EXT_external_memory_host enables importing host allocations or host-mapped foreign device memory using a host pointer as the handle. VK_EXT_external_memory_dma_buf enables importing dma_buf handles on Linux which can possibly come from another physical device.
