[Mesa-dev] [PATCH 2/7] i965: Move tex miptree and format resolving into dispatcher

Francisco Jerez currojerez at riseup.net
Thu May 7 07:15:36 PDT 2015


From: Topi Pohjolainen <topi.pohjolainen at intel.com>

All hardware platforms have this in common, so do it in the
hardware independent dispatcher.

v2 (Matt): Removed extra whitespace.
