| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed issue where we had inverted logic when checking for pending exceptions. Changed the logic to not update the native allocation watermarks after concurrent GC since the finalizers may not have been run at this point. Copied over the test from ART for ensuring that it is working. Bug: 10444866 Change-Id: Ie26170f9c4703f11e993233cdc9c5f46396fca84
| * Fix broken card table asserts.Mathieu Chartier2013-08-082-13/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We had an off by one error due to getting the card for the heap source limit. This is not a valid card when the heap is at maximum size, but doesn't need to be since we do less than comparison on it. Fixed another error where we didn't take into account the biased begin in an assert. Did a bit of refactoring by removing useless if statement. Fixes 061-out-of-memory.

| * Add low memory mode option.Mathieu Chartier2013-07-133-18/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added a low memory mode option which can be enabled by passing the flag "-XX:LowMemoryMode" to the VM. Changed dvmHeapSourceAlloc to use mspace_malloc and madvise page aligned regions of allocations back to the kernel if low memory mode is enabled. No measurable performance penalty on a benchmark which does 4 million object allocations. This seems to reduce the Dalvik total PSS by 10 - 15% on devices with large bitmaps (such as manta or flo). Another change is that cards are madvised instead of memset when cleared if low memory mode is enabled. This saves a minor amount of memory at the cost of having slightly more page faults.

* | Trim pre-Zygote fork, fix under-estimate of heap limit.Ian Rogers2012-08-223-3/+32
|/ | | | | | | | | | | | | | | | | | | Card scanning uses dvmHeapSourceGetValue to scan from the heap base to the total foot print of the heap. Trimming the Zygote may lower the footprint of the heap by creating a hole in the middle. This hole is unaccounted for in the card scanning leading to missed dirty cards. This was a regression introduced by: https://android-review.googlesource.com/#/c/41728/ as it didn't #define MORECORE_CANNOT_TRIM 1 that was previously defined here: https://android-review.googlesource.com/#/c/41731/4/libcutils/mspace.c Introduce a notion of dvmHeapSourceGetLimit so that card scanning doesn't rely on footprint. Trim the heap before forking the Zygote. This change continues to enable morecore trimming of mspaces. Change-Id: I3f0b12371097f50a1f920cac25846ca08685e7ed

This should avoid faulting in card pages that we don't actually need. This is suboptimal when parts of the card table are used briefly and then ignored for a while.

* | Replace malloc() followed by memset() to zero with calloc()Iliyan Malchev2012-02-162-10/+5
| | | | | | | | | | | | | | | | | | | | | | Bionic's calloc() is smart enough to not zero out memory if it gets that memory from an anonyous mmap. Thus, if we use malloc for large allocations, we cause unnecessary memory duplication by following the malloc() with a memset(). An even better approach would be to replace the known large calloc() calls with dvmAllocRegion() allocation. Change-Id: Id308f541c9a040d5929bf991b6c2bfdefb823c3c
