From: Marek Olšák Date: Tue, 9 Jun 2020 06:08:21 +0000 (-0400) Subject: ac/surface: don't recompute the DCC retile map for imported textures X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a1b9eb62f60290e2d5aab403b1954aca7773a1e4;p=mesa.git ac/surface: don't recompute the DCC retile map for imported textures The retile map is not used in this case, and the retile map computation takes 39% of CPU time when resizing a window. This brings it down to 23%. The dcc_retile_use_uint16 setting has to be derived from DCC sizes.
