Though it squeezes fragmentation most aggressively, an extra\ncopy is required to re-establish the data in the ROS/DlMalloc space to allow\nCMS GCs to happen afterwards. As semispace copy GC is still stop-the-world,\nthis not only introduces unnecessary overheads but also longer response time.\nResponse time indicates the time duration between the start of transition\nrequest and the start of transition animation, which may impact the user\nexperience.\n\nUsing semispace copy GC to compact the data in a ROS space to another ROS(or\nDlMalloc space to another DlMalloc) space solves this problem. Although it\nsqueezes less fragmentation, CMS GCs can run immediately after the compaction.\n\nWe apply this algorithm in two cases:\n1) Right before throwing an OOM if -XX:EnableHSpaceCompactForOOM is passed in\nas true.\n2) When app is switched to background if the -XX:BackgroundGC option has value\nHSpaceCompact.\n\nFor case 1), OOMs are significantly delayed in the harmony GC stress test,\nwith compaction ratio up to 0.87. For case 2), compaction ratio around 0.5 is\nobserved in both built-in SMS and browser.

The new\nmode is finding the first free bit in the bitmap. This was\npreviously the slow path but is now the fast path. Some optimizations\nwhich enabled this include always having the alloc bitmap bits which\ncorrespond to invalid slots be set to 1. This prevents us from needing\na bound check since we will never end up allocating there.\n\nChanged revoking thread local buffer to point to an invalid run. The\ninvalid run is just a run which always has all the allocation bits set\nto 1. When a thread attempts to do a thread local allocation from here\nit will always fail and go slow path. This eliminates the need for a\nnull check for revoked runs.\n\nChanged zeroing of memory to happen during free, AllocPages should\nalways return zeroed memory. Added prefetching which happens when we\nallocate a run.\n\nSome refactoring to reduce duplicated code.\n\nErgonomics changes: Changed kStickyGcThroughputAdjustment to 1.0,\nthis helps reduce GC time.\n\nMeasurements (3 samples per benchmark):\nBefore: MemAllocTest scores: 3463, 3445, 3431\nEvaluateAndApplyChanges score | total GC time\nIter 1: 3485, 23.602436s\nIter 2: 3434, 22.499882s\nIter 3: 3483, 23.253274s\n\nAfter: MemAllocTest scores: 3495, 3417, 3409\nEvaluateAndApplyChanges score | total GC time:\nIter 1: 3375, 17.463462s\nIter 2: 3358, 16.185188s\nIter 3: 3367, 15.822312s\n\nBug: 8788501\nBug: 11790317\nBug: 9986565\nChange-Id: Ifd273a054824028dabed27c07c081dde1816f93c\n" }, { "commit": "8585bad7be19ee4901333f7d02d1d4d3f04877d4", "tree": "be30d58fc4fd71a4fcbdffa0d19a4bf9aaaa4c50", "parents": [ "82b1a81890970a8b07f9132aeae537a6c43df6b0" ], "author": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Fri Apr 11 17:53:48 2014 -0700" }, "committer": { "name": "Mathieu Chartier", "email": "mathieuc@google.com", "time": "Tue Apr 22 10:57:22 2014 -0700" }, "message": "Return bytes freed from RosAlloc.\n\nThere was a problem with how RosAlloc space sweeping worked caused by\nusing the object size in the FreeList call, this won\u0027t work well with\nclass unloading since the object\u0027s class may be freed before the\nobject.\n\nBug: 13989231\nChange-Id: I3df439c312310720fd34249334dec85030166fe9\n" }, { "commit": "d9a88de76de4c81ad75340b824df64a68c739351", "tree": "c73fdb6fc236152b330407a30ce885463799bccd", "parents": [ "b7a691f6398c55dacb3531d921e8cb298c3c8b8d" ], "author": { "name": "Hiroshi Yamauchi", "email": "yamauchi@google.com", "time": "Mon Apr 07 13:52:31 2014 -0700" }, "committer": { "name": "Hiroshi Yamauchi", "email": "yamauchi@google.com", "time": "Mon Apr 07 16:07:04 2014 -0700" }, "message": "Implement rosalloc page trimming without suspending threads.\n\nAlso, making it more efficient by not going through the chunks smaller\nthan the page size by not using InspectAll().\n\nChange-Id: I79ceb0374cb8aba5f6b8dde1afbace9af98b6cff\n" }, { "commit": "c93c530efc175954160c3834c93961a1a946a35a", "tree": "32a389e2b4cfc3296075aed23f353b8d3042c9a5", "parents": [ "faa93b3ab455492dad1a9d3fb630e3936d389c85" ], "author": { "name": "Hiroshi Yamauchi", "email": "yamauchi@google.com", "time": "Thu Mar 20 16:15:37 2014 -0700" }, "committer": { "name": "Hiroshi Yamauchi", "email": "yamauchi@google.com", "time": "Fri Mar 21 12:17:56 2014 -0700" }, "message": "Revoke rosalloc thread-local buffers at the checkpoint.\n\nIn the mark sweep collector, rosalloc thread-local buffers were\nrevoked during the pause.
