From dfe2f198550b262186e2882d7e573f1f3759deb7 Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Mon, 19 Mar 2018 22:23:55 +1100 Subject: st/nir: fix atomic lowering for gallium drivers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit i965 and gallium handle the atomic buffer index differently. It was just by luck that the single piglit test for this was passing. For gallium we use the atomic binding so that we match the handling in st_bind_atomics(). On radeonsi this fixes the CTS test: KHR-GL43.shader_storage_buffer_object.advanced-write-fragment It also fixes tressfx hair rendering in Tomb Raider.
