Subject: intel/isl: Refactor to use a phys_total_el extent.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=044bfb292fbeae98c0256bf995ce7afac5102c53;p=mesa.git

intel/isl: Refactor to use a phys_total_el extent.

We've already implicitly been using a physical total size in surface
elements.  This just centralizes things a bit.
