From fcbb93e860246375d03f280f927f79d3645a8988 Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Thu, 15 Jun 2017 11:56:28 +1000 Subject: [PATCH] mesa: stop assigning unused storage for non-bindless opaque types The storage was once used by get_sampler_uniform_value() but that was fixed long ago to use the uniform storage assigned by the linker. By not assigning storage for images/samplers the constant buffer for gallium drivers will be reduced which could result in small perf improvements.
