--- Comment #4 from Jordan Justen <jljusten at gmail.com> ---
I tested the hiz buffer size allocated for this piglit command:
bin/depthstencil-render-miplevels 1024 d=z24

When using patches 1-5 of my bwd-aux-hiz branch in
git://people.freedesktop.org/~jljusten/mesa

For gen7 and gen8:
master=7340032
patches1-5=917504

This seems to match Paul's comment that it is roughly 8
times larger than necessary.
