Remember that using resources that alias in memory requires proper synchronization. You need to issue a memory barrier to make sure commands that use img1
and img2
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 img1
and then want to use img2
, you need to issue an image memory barrier for img2
with oldLayout
= VK_IMAGE_LAYOUT_UNDEFINED
.
VMA also provides convenience functions that create a buffer or image and bind it to memory represented by an existing VmaAllocation: vmaCreateAliasingBuffer(), vmaCreateAliasingBuffer2(), vmaCreateAliasingImage(), vmaCreateAliasingImage2(). Versions with "2" offer additional parameter allocationLocalOffset
