From adcf8f8a13717f7eb53b2aa86c4b56e344f2f317 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 13 May 2015 22:56:07 +0200 Subject: [PATCH] softpipe: enable ARB_texture_view Some bits were already there for texture views but some were missing. In particular for cube map views things needed to change a bit. For simplicity I ended up removing the separate face addr bit (just use the z bit) - cube arrays didn't use it already, so just follow the same logic there. (In theory using separate bits could allow for better hash function but I don't think anyone ever did some measurements of that so probably not worth the trouble, if we'd reintroduce it we'd certainly wanted to use the same logic for cube arrays and cube maps.) Also extend the seamless cube sampling to cube arrays - as there were no piglit failures before this is apparently untested, but things now generally work quite the same for cube textures and cube array textures so there hopefully shouldn't be any trouble... 49 new piglits, 47 pass, 2 fail (both due to fake multisampling). v2: incorporate Brian's feedback, add sampler view validation, function rename, formatting fixes.
