2012-12-10Revert "revert "Revert "mm: remove __GFP_NO_KSWAPD""" and associated damageLinus Torvalds
This reverts commits a50915394f1fc02c2861d3b7ce7014788aa5066e and d7c3b937bdf45f0b844400b7bf6fd3ed50bac604. This is a revert of a revert of a revert. In addition, it reverts the even older i915 change to stop using the __GFP_NO_KSWAPD flag due to the original commits in linux-next. It turns out that the original patch really was bogus, and that the original revert was the correct thing to do after all. We thought we had fixed the problem, and then reverted the revert, but the problem really is fundamental: waking up kswapd simply isn't the right thing to do, and direct reclaim sometimes simply _is_ the right thing to do. When certain allocations fail, we simply should try some direct reclaim, and if that fails, fail the allocation. That's the right thing to do for THP allocations, which can easily fail, and the GPU allocations want to do that too. So starting kswapd is sometimes simply wrong, and removing the flag that said "don't start kswapd" was a mistake. Let's hope we never revisit this mistake again - and certainly not this many times ;) Acked-by: Mel Gorman <mgorman@suse.de> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Cc: Rik van Riel <riel@redhat.com> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-11-25Revert "drm/i915: enable rc6 on ilk again"Chris Wilson
Even with the cumulative set of ilk w/a, rc6 is demonstrably still failing and causing GPU hangs as found by Peter Wu. So we need to disable it again until it is stable. This reverts commit 456470eb583f063ee84c6818251e638598be0fb8 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Aug 8 23:35:40 2012 +0200 drm/i915: enable rc6 on ilk again and the follow-on commit cd7988eea561a70a4f98e431c1395f913672d626 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun Aug 26 20:33:18 2012 +0200 drm/i915: disable rc6 on ilk when vt-d is enabled Note: The situation around the gen4/5 gpu hangs that cropped up in 3.7 is rather strange. Most useful bisects have lead to commit 6c085a728cf000ac1865d66f8c9b52935558b328 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Aug 20 11:40:46 2012 +0200 drm/i915: Track unbound pages or even later commits that affect the gem bo recycling, which all is way past the point where we re-enabled rc6. But somehow reverting/disabling those commits doesn't help, but disabling rc6 at least helps for many hangs on ilk. Obviously it doesn't change anything at all on gen4, and there are still strange issues left on gen5 (which we unfortunately can't readily reproduce). Also, the error_state signature of the hangs which can be fixed with this patch look remarkably different to those which seem to be unaffected by the rc6 settings: The rc6 hangs are in the ring, somewhere in the MI_FLUSH/PIPE_CONTROL sequence to make ilk coherent, wheras all the other hangs tend to be at a random point in the middle of the user batch. So it could also be that we have different issues. Until we grow more clue, this at least helps some users.
