36 * This file contains all of the stuff for emitting commands into a command
37 * buffer. This includes implementations of most of the vkCmd*
38 * entrypoints. This file is concerned entirely with state emission and
39 * not with the command buffer data structure itself. As far as this file
40 * is concerned, most of anv_cmd_buffer is magic.
