How would you like the support for these extensions to look like in the interface of this library? You can already add VkExternalMemoryImageCreateInfoKHR
structure to the pNext
chain of the
VkImageCreateInfo
structure.

So we don't have to add VkExportMemoryAllocateInfoKHR in the pNext of the VkMemoryAllocateInfo? I thought you have to specify both.

You are right. I will add support for these extensions to my TODO list to implement it some time in the future.

Great. Thanks
from vulkanmemoryallocator.
I considered what structures could be passed in pNext
chain of VkMemoryAllocateInfo
regarding import/export:
VkExportMemoryAllocateInfoKHR
VkExportMemoryAllocateInfoNV
VkExportMemoryWin32HandleInfoKHR
VkExportMemoryWin32HandleInfoNV
VkImportMemoryWin32HandleInfoKHR
VkImportMemoryWin32HandleInfoNV
VkImportMemoryFdInfoKHR
VkImportMemoryHostPointerInfoEXT
And I concluded that there is no convenient way to pass all the required parameters to this library. Allocations for imported/exported external memory tend to require explicit memory type index and dedicated allocation anyway, so they don't interact with main features of this library.
So I don't want to implement any support for it. I believe that such special purpose allocations should be made manually, using vkCreateBuffer
and vkAllocateMemory
.
