From 72df3a7a3957a13c4a667ffb2295ced7b91e5620 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 21 Feb 2018 13:57:39 -0700 Subject: [PATCH] svga: if svga_update_state() fails, skip the draw call If svga_update_state() fails, we flush the command buffer and retry. If it fails again, it likely means we were unable to translate a shader for some reason (uses too many resources, for example). In that case, let's just skip the draw call. The alternative, just disabling the shader stage in question, would certainly lead to bad rendering anyway, and probably device errors. Fixes failed assertion running Piglit glsl-1.50/execution/ variable-indexing/gs-output-array-vec4-index-wr.shader_test since it uses too many GS output registers (though the test still fails). VMware bug 2063492. v2: also call pipe_debug_message() so apps or apitrace can be notified when this issue occurs. v3: use svga_update_state_retry().
