From 2b7ba9f239c09049408d86eb71be18887691dc58 Mon Sep 17 00:00:00 2001 From: Rafael Antognolli Date: Mon, 19 Aug 2019 17:01:10 -0700 Subject: [PATCH] anv: Only re-emit non-dynamic state that has changed. On commit f6e7de41d7b, we started emitting 3DSTATE_LINE_STIPPLE as part of the non-dynamic state. That gets re-emitted every time we bind a new VkPipeline. But that instruction is non-pipelined, and it caused a perf regression of about 9-10% on Dota2. This commit makes anv_dynamic_state_copy() return a mask with only the state that has changed when copying it. 3DSTATE_LINE_STIPPLE won't be emitted anymore unless it has changed, fixing the problem above. v2: Improve commit message and add documentation about skipped checks (Jason) Fixes: f6e7de41d7b ("anv: Implement VK_EXT_line_rasterization") Reviewed-by: Jason Ekstrand Reviewed-by: Lionel Landwerlin --- src/intel/vulkan/anv_cmd_buffer.c | 68 +++++++++++++++++++++---------- src/intel/vulkan/anv_private.h | 6 +-- 2 files changed, 50 insertions(+), 24 deletions(-) diff --git a/src/intel/vulkan/anv_cmd_buffer.c b/src/intel/vulkan/anv_cmd_buffer.c index 96c75e06ae8..59a281d6053 100644 --- a/src/intel/vulkan/anv_cmd_buffer.c +++ b/src/intel/vulkan/anv_cmd_buffer.c @@ -78,46 +78,72 @@ const struct anv_dynamic_state default_dynamic_state = { }, };
