2012-08-02Use thread progress instead of scheduling misc aux work were possibleRickard Green
Functionality for scheduling operations at thread progress later has been introduced. Deallocation of ETS table structures were previously done by scheduling misc aux work. Deallocation of process structures (not released yet) was also implemented this way. Instead of using the misc aux work functionality these implementation now use the newly introduced functionality for scheduling operations at thread progress later. By using this new functionaliy we reduce the amount of memory allocation/deallocation operations needed.

* rickard/dealloc/OTP-10162: Improve the enqueue operation of delayed dealloc Implement delayed aux work wake up
2012-07-31Implement delayed aux work wake upRickard Green
By using a delayed aux work wake up approach, a memory barrier can be omitted in the delayed dealloc enqueue operation. The amount of operations, on the potentially contended, wake up structure is also reduced.

2012-06-25Don't go to single-scheduler mode when managing breakpointsBjörn Gustavsson
Calls to erlang:set_trace_pattern/3 will no longer block all other schedulers. We will still go to single-scheduler mode when new code is loaded for a module that is traced, or when loading code when there is a default trace pattern set. That is not impossible to fix, but that requires much closer cooperation between tracing BIFs and the loader BIFs.

* rickard/thr-prgr-use/OTP-10116: Fix faulty use of thread progress in handle_aux_work()
2012-06-18Fix faulty use of thread progress in handle_aux_work()Rickard Green
As an optimization old thread progress data was kept and used in handle_aux_work() in erl_process.c. This could cause memory to be deallocated at a later time than intended, which is quite harmless. This has, however, now been fixed.

2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.
