I have a question about vulkan. Lets say, I have a texture, for which I generated mip chain using compute shader. For that I needed to place a resource barrier, but after that not all mips(subresources) in the same state. What will happen, if I need to transfer this resource from one state to another? Can I just do a standard image barrier which will use VK_REMAINING_MIP_LEVELS, or I would need to check if all resources in the same state and, if not, set image barrier for each mip to transfer all subresources to desired state?

You can use barriers on sub resources like it’s layers and mipmaps. Check the mipmap part of vulkan tutorial for some example.
