Subject: i965: Fix packed depth/stencil textures to be Y-tiled as well.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e0a4e25f938953201fef2bf702e2e709451200f4;p=mesa.git

i965: Fix packed depth/stencil textures to be Y-tiled as well.

Fixes shadowtex.c.  And an assert is added to catch this sooner next time.
