Subject: i965: use mt->offset in intel_miptree_map_movntdqa()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4c4bfed6709c7c35de4b2268ca2e73ed75c30f50;p=mesa.git

i965: use mt->offset in intel_miptree_map_movntdqa()

We need to include mt->offset in the calculation of src pointer because its
value may be non-zero, for example in a cubemap texture.
