From ce4058dafd2dd283addaa99e8d5b51e53f634f9b Mon Sep 17 00:00:00 2001 From: Alex Smith Date: Thu, 16 Mar 2017 16:40:07 +0000 Subject: [PATCH] radv/ac: Fix shared memory offset calculation The index passed to get_shared_memory_ptr is an attribute slot index, i.e. the index of a vec4 within LDS. Therefore this must be scaled by sizeof(vec4) to give the LDS byte offset.
