Subject: anv: enable sampling from fast-cleared images on SKL
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c4c02471f485e6e9a8ffdaaa789861dcd5a3b8e9;p=mesa.git

anv: enable sampling from fast-cleared images on SKL

A resolve is not needed on Skylake in this case. We were forcing
a resolve because we set the input_aux_usage to ISL_AUX_USAGE_NONE.
