From abdb320af446226e23ccb1f0b6a271d19596e2a9 Mon Sep 17 00:00:00 2001 From: Bas Nieuwenhuizen Date: Tue, 7 Apr 2020 22:23:09 +0200 Subject: radv: Consider maximum sample distances for entire grid. The other pixels in the grid might have samples with a larger distance than the (0,0) pixel. Fixes dEQP-VK.pipeline.multisample.sample_locations_ext.verify_location.samples_8_packed when CTS is compiled with clang.
