From 8ae93c68ea3538e9e2c2462710a87192e026238d Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 18 Jun 2012 10:22:06 -0600 Subject: svga: fix synchronization bug between sampler views and surfaces MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This fixes a bug where a sampler view was using stale texture/resource data when the texture was modified through a surface (render to texture). Bumping the texture and layer ages triggers sampler view revalidation. Fixes piglit fbo-blit failure.
