From 47caefc7b4e239bb7e9486a799e618e5614e4924 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 26 Dec 2018 23:15:30 -0800 Subject: [PATCH] v3d: Force sampling from base level for tg4. This is what the GLSL ES 310 spec tells us to do, but apparently the "gather mode" flag doesn't imply it in the HW.
