Subject: i965: Account for MinLayer in CopyImageSubData's blitter/CPU paths.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1b39c5efcabb7c4676c57ddc01d37edcce0f2d03;p=mesa.git

i965: Account for MinLayer in CopyImageSubData's blitter/CPU paths.

Fixes Piglit's arb_copy_image-texview test with the Meta path disabled
(so we hit the blitter/CPU fallback paths).

v2: Add MinLayer even for cube maps (suggested by Ilia).
