stack trace
could it be a single blit taking more than 30s?
traces like this are usually the gtt-mapping faulting choosing the wrong thing to kick out and userland not making progress or making very slow progress. If so, sysprof will show all your time in page faulting. Unfourtunatly, sysprof doesn't report in-kernel time for me :-/ Could you give it a try, please? However, the web-page mentioned contains a huge amount of large images scaled down, so you explanation sounds quite logical. I've done some work recently in this area and already have had one patch shot down in flames that should help address this issue... So reassigning to myself. *** Bug 26522 has been marked as a duplicate of this bug. *** still happens with intel-2.10.901 + kernel-2.6.32.8 :/ Created attachment 35511 [details] [review] Protect mmapped buffers from casual eviction. Clemens/Okias, does this still exist? Can you try Chris's patch? I don't have laptop with intel card with me, so I will be able test it when I got it in my hands, which will be circa 22.8. Done! commit e2bf07fe23fd11a2acba609bf34ccc59c5553389 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat Aug 7 11:01:24 2010 +0100 drm/i915: Implement fair lru eviction across both rings. (v2) Based in a large part upon Daniel Vetter's implementation and adapted for handling multiple rings in a single pass. This should lead to better gtt usage and fixes the page-fault-of-doom triggered. The fairness is provided by scanning through the GTT space amalgamating space in rendering order. As soon as we have a contiguous space in the GTT large enough for the new object (and its alignment), evict any object which lies within that space. This should keep more objects resident in the GTT. Doing throughput testing on a PineView machine with cairo-perf-trace indicates that there is very little difference with the new LRU scan, perhaps a small improvement... Except oddly for the poppler trace.
