Subject: anv/image: Use custom VkBufferImageCopy for iview initialization
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d3c1fd53e284db7e8a63e8fd1d9219c710a2890e;p=mesa.git

anv/image: Use custom VkBufferImageCopy for iview initialization

Use a custom VkBufferImageCopy with the user-provided struct as
the base. A few fields are modified when the iview is uncompressed
and the underlying image is compressed.
