Another overwritten batch, going with commit c501ae7f332cdaf42e31af30b72b4b66cbbb1604 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Dec 14 13:57:23 2011 +0100 drm/i915: Only clear the GPU domains upon a successful finish By clearing the GPU read domains before waiting upon the buffer, we run the risk of the wait being interrupted and the domains prematurely cleared. The next time we attempt to wait upon the buffer (after userspace handles the signal), we believe that the buffer is idle and so skip the wait. until proven otherwise. Proof otherwise. Patch already included in ubuntu-precise's kernel: commit 89df7051aab3884a734fc1eb666322643519c9c8 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Dec 14 13:57:23 2011 +0100 drm/i915: Only clear the GPU domains upon a successful finish commit c501ae7f332cdaf42e31af30b72b4b66cbbb1604 upstream. Another suspicious clear. Please re-test with mesa master or 8.0.3+ with: commit 93e94cbb48a679b7bf67594adb6f858526b37935 Author: Eric Anholt <eric@anholt.net> Date: Fri Feb 10 12:54:25 2012 -0800 intel: Fix rendering from textures after RenderTexture(). Also, we really need some specific application and steps to reproduce the problem with if we're going to make progress by anything other than luck. No response from bug filer for 2 years. |
