Known issue, but I haven't seen it triggered from x11perf before. The only workaround so far is DebugFlushCaches. The only explanation I have so far is a hw bug... The patch for intel_uxa.c you listed under bug 27892 seemed to resolve this for the time being - making this a very good day for me thank you. Until now I have yet to successfully run x11perf -all as it would hang always on copywinwin10 or copypixpix10 tests. For some reason running under gnome environment vs single user would allow the copywinwin tests to pass only to fail on copypixpix10. Hi Matthew, it seems although we still haven't got a clue as to why it dies, we have a workaround that doesn't penalise too much. Can you please retry with the current master of xf86-video-intel? commit 46f97127c22ea42bc8fdae59d2a133e4b8b6c997 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sun Oct 16 21:40:15 2011 +0100 snb,ivb: Workaround unknown blitter death The first workaround was a performance killing MI_FLUSH_DW after every op. This workaround appears to be a stable compromise instead, only requiring a redundant command after every BLT command with little impact on throughput.
