Subject: vk/image: Add more info to VkImageViewType table
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=69e11adeccce1ef054f01dbb1f4c062e2b3eeea2;p=mesa.git

vk/image: Add more info to VkImageViewType table

Convert the table from the direct mapping
  VkImageViewType -> SurfaceType

into a mapping to an info struct
  VkImageViewType -> struct anv_image_view_info
