2013-04-15erts: Fix locking order violation for allocation wrappersSverker Eriksson
Some query functions in erl_alloc_util.c lock the allocator mutex and then use erts_printf that in turn may call the sys allocator through the wrappers. To avoid breaking locking order these query functions first "pre-locks" all allocator wrappers.

2013-04-02erts: Fix benign size-bug for fix-allocators MONITOR_SH and NLINK_SHSverker Eriksson
Bug will (as it seems) only result in faulty statistics.

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.

2012-03-22Add user tag spreading functionality to VM and use in filePatrik Nyblom
User tags in a dynamic trace enabled VM are spread throughout the system in the same way as seq_trace tokens. This is used by the file module and various other modules to get hold of the tag from the user process without changing the protocol.

2011-11-13Use generic lock-free queue for misc aux workRickard Green
2011-11-13Implement generic lock-free queueRickard Green
The implementation of an ERTS internal, generic, many to one, lock-free queue for communication between threads. The many to one scenario is very common in ERTS, so it can be used in a lot of places in the future. Changing to this queue from a lock based queue, however, often requires some redesigning. This since we have often used the lock of the queue to protect other information too.
2011-11-13Replace system block with thread progress blockRickard Green
The ERTS internal system block functionality has been replaced by new functionality for blocking the system. The old system block functionality had contention issues and complexity issues. The new functionality piggy-backs on thread progress tracking functionality needed by newly introduced lock-free synchronization in the runtime system. When the functionality for blocking the system isn't used there is more or less no overhead at all. This since the functionality for tracking thread progress is there and needed anyway.
2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.
