[Mesa-dev] [PATCH 4/5] i965/miptree: Rename align_w, align_h -> halign, valign
Chad Versace
chad.versace at intel.com
Fri Sep 25 12:05:49 PDT 2015
The values of intel_mipmap_tree::align_w and ::align_h correspond to the
hardware enums HALIGN_* and VALIGN_*.
See the confusion?
align_h != HALIGN
align_h == VALIGN
Reduce the confusion by renaming the variables to match the hardware
enum names:
git ls-files |
xargs sed -i -e 's/align_w/halign/g' \
-e 's/align_h/valign/g'
