From a077185ea9d685967844b68aa09da6bd8aa430da Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Wed, 12 Oct 2016 03:06:08 +0200 Subject: [PATCH] gallium: add PIPE_RESOURCE_FLAG_TEXTURING_MORE_LIKELY MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit For performance tuning in drivers. It filters out window system framebuffers and OpenGL renderbuffers. radeonsi will use this to guess whether a depth buffer will be read by a shader. There is no guarantee about what will actually happen. This is a departure from PIPE_BIND flags which are defined to be strict but they are useless in practice.
