From: Marek Olšák Date: Wed, 12 Oct 2016 01:06:08 +0000 (+0200) Subject: gallium: add PIPE_RESOURCE_FLAG_TEXTURING_MORE_LIKELY X-Git-Tag: upstream/17.1.0~5653 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a077185ea9d685967844b68aa09da6bd8aa430da;p=platform%2Fupstream%2Fmesa.git gallium: add PIPE_RESOURCE_FLAG_TEXTURING_MORE_LIKELY 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.
