CUDA/Vulkan Interop for optimally tiled images #169

Closed christosa-rfpro closed 7 months ago

Hi. It's currently possible to share the memory of Vulkan images that use linear tiling (VK_IMAGE_TILING_LINEAR). Do you also plan to support optimally tiled images (VK_IMAGE_TILING_OPTIMAL)?

Hi. Currently images can be shared only through buffer sharing. This way only VK_IMAGE_TILING_LINEAR can be supported because VK_IMAGE_TILING_OPTIMAL is an unknown, device-dependent layout.

So to be able to share images with VK_IMAGE_TILING_OPTIMAL layout, buffer sharing cannot be used, and image/texture sharing would be necessary. This may be supported in the future but there are no immediate plans for this yet.

Fair enough, thanks.
