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.

2011-11-13Implement 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The ERTS internal system block functionality has been replaced by new functionality for blocking the system.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.

2011-09-29Skip create_big_boot on platforms without cryptoLukas Larsson
This has to be done as many other applications depend on that crypto is present.
2011-09-29Remove test_server path instead of cwd for clash testLukas Larsson
With the introduction of common_test as test framework the working directory of the tests changed to be the emulator_test directory. So we now have to remove the ../test_server directory instead. This change only affect tests run with a emulator which has not been installed.

2011-09-29Use static port for old solaris versionsLukas Larsson
Solaris version before 10 have some problem with releasing addresses after doing a gen_udp:open, which causes inet_res to get a econnrefused. With this fix we hope that the static port will not collide with anything.

This change was made in order to make slow solaris machines work.

This is done in order to improve timing when testing debug builds, especially ppc debug builds.

Emakefile contained compile flags that caused compilation of suites to fail in some cases. common_test will generate an Emakefile and diameter has no need for one of its own.
