In the Vulkan manual pages, the command functions all have a 'Command Properties' box at the bottom that specifies Command Buffer Levels, Render Pass Scope, etc... See https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkCmdBindPipeline.html for an example.
The last column is 'Pipeline Type'. Under most commands this is left empty, but occasionally this has the entry 'Transfer' (ex. https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkCmdClearDepthStencilImage.html). I don't know what that actually means. In Vulkan there are only two types of pipelines, compute and graphics, there's no notion of a 'Transfer' pipeline, you can't create one, you can't bind one, it doesn't exist. There is the notion of different queue types, compute, graphics, and transfer; but the chart already has a column called 'Supported Queue Types'.
Anyone have any ideas what that column means/is used for?
