From a36f1542ae4c8cf86e586cde6c06f298f30d7c0d Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 17 Jun 2019 06:55:07 -0500 Subject: [PATCH] iris: Order CS stall and TC invalidate for format reinterpretation hacks This should ensure the TC invalidate happens after the stall. Fixes KHR-GL43.copy_image.functional which does a CopyImage (blorp_copy) from a buffer (using R8G8B8A8_UINT), then GetTexImage to read back the original image (using R10G10B10A2_UNORM). --- src/gallium/drivers/iris/iris_blit.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/src/gallium/drivers/iris/iris_blit.c b/src/gallium/drivers/iris/iris_blit.c index 5861c96..95209cb 100644 --- a/src/gallium/drivers/iris/iris_blit.c +++ b/src/gallium/drivers/iris/iris_blit.c @@ -289,9 +289,8 @@ tex_cache_flush_hack(struct iris_batch *batch) * * TODO: Remove this hack! */ - iris_emit_pipe_control_flush(batch, - PIPE_CONTROL_CS_STALL | - PIPE_CONTROL_TEXTURE_CACHE_INVALIDATE); + iris_emit_pipe_control_flush(batch, PIPE_CONTROL_CS_STALL); + iris_emit_pipe_control_flush(batch, PIPE_CONTROL_TEXTURE_CACHE_INVALIDATE); } /** -- 2.7.4
