From c10808441cc479b715caf21d993866dc396397d9 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Mon, 6 May 2019 16:17:26 +0200 Subject: [PATCH] radv: fix rowPitch for R32G32B32 formats on GFX9 The pitch is actually the number of components per row. We found the problem when we implemented some meta operations for these formats and the wrong pitch has been confirmed with a small test case.
