Subject: Add a dri config option to enable the max texture level hack
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4932ba28adc2694161ec3fa7964cd76e3742182a;p=mesa.git

Add a dri config option to enable the max texture level hack
make ycbcr depend on a CHIPSET define .. needs to be filled in though
