Do you indicate mesa master works? (In reply to comment #2) > Do you indicate mesa master works? I have try the mesa(master) commit 60302f83e2344195f9a1c37215def09fa9c45ff9 Author: Marek Olšák <maraeo@gmail.com> Date: Tue Nov 8 23:19:03 2011 +0100 r600g: clarify meaning of one variable in shader codegen It's easier to read now. It is the same issue, even more, the system will hung Ken, can you reproduce? Hello, I have found when I set i915.semaphores=1, this game will not hangs Are there any messages about missed interrupts? This sounds a lot like bug #38862. (In reply to comment #6) > Are there any messages about missed interrupts? This sounds a lot like bug > #38862. Yes, there are some Miss IRQ info like "[drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 20869, at 20869], missed IRQ?" I'd rather track this (freeze) issue as seperate of bug#38862, unless there's a patch fixing both. tested in 3.2-rc6, with gpu semaphores enabled by default on IVB. and no such issue A patch referencing this bug report has been merged in Linux v3.2-rc6: commit f45b55575cedb7efa782e43f1ea74338456d0381 Author: Eugeni Dodonov <eugeni.dodonov@intel.com> Date: Fri Dec 9 17:16:37 2011 -0800 drm/i915: enable semaphores on per-device defaults |
