Subject: i965/gen7 renderbuffer: Set depth size based on LOD0 for 3D textures
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b875f39e2967fa383e2c896bc354429fe10cd7a5;p=mesa.git

i965/gen7 renderbuffer: Set depth size based on LOD0 for 3D textures

If blorp is disabled for color clears, then piglit's
'gl-3.2-layered-rendering-clear-color-all-types 3d mipmapped'
will fail.

Currently, gen8 fails similarly on this test because gen8
does not use blorp.
