Author: Gert Wollny <[email protected]> Date: Mon Nov 19 07:56:09 2018 +0100 r600: Only set context streamout strides info from the shader that has outputs With 5d517a streamout info is only attached to the shader for which the transform feedback is actually recorded, but the driver set the context info with each state submitted, thereby always using the info data that was attached to the vertex shader. Pass the streamout stride info to the context only from the shader that actually has outputs. (Thanks to Marek Olšák for pointing me in the right direction) Fixes regresion with: dEQP-GLES31.functional.tessellation.invariance.* Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108734 Fixes: 5d517a599b1eabd1d5696bf31e26f16568d35770 st/mesa: Don't record garbage streamout information in the non-SSO case.
