From 66b4a7a79e3da03e11233acd32b6e37bf3969dd8 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Fri, 20 Oct 2017 15:53:50 -0700 Subject: i965: Call gen6_upload_push_constants() even when the stage is disabled. This properly sets stage_state->push_constant_dirty = true, so that we emit 3DSTATE_CONSTANT_XS to disable the constant buffer for the shader stage. It also sets stage_state->push_const_size = 0.
