From 02f5512fed2e6fc2b92a32623fb979117d41239b Mon Sep 17 00:00:00 2001 From: Nanley Chery Date: Thu, 26 Apr 2018 17:09:29 -0700 Subject: [PATCH] intel/blorp: Add a NO_UPDATE_CLEAR_COLOR batch flag Allow callers to handle updating the indirect clear color buffer themselves. This can reduce the number of clear color updates in the case where a caller performs multiple fast clears with the same clear color.
