From 7b46f09f26c3f4377f46d145344f98d5b27b0b00 Mon Sep 17 00:00:00 2001 From: Alyssa Rosenzweig Date: Thu, 20 Jun 2019 08:19:06 -0700 Subject: [PATCH] panfrost: Fix tiled NPOT textures with bpp<4 Panfrost's tiling routines (incorrectly) ignored the source stride, masking this bug; lima's routines respect this stride, causing issues when tiling NPOT textures whose stride is not a multiple of 64 (for instance, NPOT textures with bpp=1).
