2011-12-06erts: Remove truncation of http packet parsing and return error insteadSverker Eriksson
This is a slight modification of previous commit by Steve Vinoski For backward compatibility of old users of decode_packet, I think it's enough to return error instead of keeping the old line truncation behaviour.

2011-12-01Deprecate erlang:system_flag/2 arguments scheduler_bind_type and cpu_topologyRickard Green
The use of erlang:system_flag(scheduler_bind_type, _) and erlang:system_flag(cpu_topology, _) have been deprecated and scheduled for removal in erts-5.10/OTP-R16. For more information see the documentation of erlang:system_flag/2.

* rickard/default-unbound/OTP-9726: Use unbound schedulers as default
2011-11-29erts: Deprecate the NIF reload mechanismSverker Eriksson
The reload mechanism is an odd feature that does not harmonize with how module upgrade is otherwise done. We do not want its presence to hinder future development of code loading and upgrade.
2011-11-18Use unbound schedulers as defaultRickard Green
As of ERTS version 5.9 (OTP-R15B) the runtime system will by default not bind schedulers to logical processors. If the Erlang runtime system is the only operating system process that binds threads to logical processors, this improves the performance of the runtime system. However, if other operating system processes (as for example another Erlang runtime system) also bind threads to logical processors, there might be a performance penalty instead. In some cases this performance penalty might be severe. Due to this, we change the default so that the user must make an active decision in order to bind schedulers.

2011-11-13Use generic lock-free queue for async threadsRickard Green
Queues used for communication between async threads and scheduler threads have been replaced with lock-free queues. Drivers using the driver_async functionality are not automatically locked to the system anymore, and can be unloaded as any dynamically linked in driver. Scheduling of ready async jobs is now also interleaved in between other jobs. Previously all ready async jobs was performed at once.
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.
