Subject: i965: Adjust map/unmap code for MinLevel/MinLayer
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ba3499ba01135c54d9b28a4bae916845cdbb64b7;p=mesa.git

i965: Adjust map/unmap code for MinLevel/MinLayer

This allows core mesa's TexSubImage paths etc to work correctly
with views which have nonzero MinLevel or MinLayer.
