2013-06-19erts: Make aoffcbf default when migration is enabledSverker Eriksson
2013-06-19erts: Add new allocator strategy aoffcbfSverker Eriksson
with better performance than aoffcaobf as we don't have to rearrange the search tree when there are blocks of equal size.
2013-06-04erts: Carrier pool information in allocator informationRickard Green
That is, include information about carrier pool in result returned from erlang:system_info({allocator,allocator_sizes, _}).
2013-06-04erts: Use carrier pool for migration of carriersRickard Green

2013-06-04erts: Fix type errors in info functionsRickard Green
2013-06-04erts: Use Uint64 for call countsRickard Green
2013-06-03erts: Rename allocator aoffcbf to aoffcaobfSverker Eriksson
and add documentation in erts_alloc
2013-06-03erts: Remove unnecessary flag arguments in allocatorsSverker Eriksson
A cleanup after SBMBC was removed.
2013-06-03erts: Remove SBMBC allocatorSverker Eriksson
2013-06-03erts: Add test for add_mbc and remove_mbc callbacksSverker Eriksson
2013-06-03erts: Fix deallocation in removed carrierSverker Eriksson
2013-06-03erts: Change naive list to rb-tree of carriers in AOFF allocatorSverker Eriksson
and add new callbacks add_mbc(), remove_mbc() and largest_fblk_in_mbc() for carrier migration.
2013-06-03erts: Prepare aoff allocator for carrier migrationSverker Eriksson
by putting blocks from different carrier into separate search trees. Carriers are currently organized in a naive linked list by address order.
2013-06-03erts: Make carrier header sizes customizableSverker Eriksson
This is a modified partial revert of 2ab1d972f6fd37c17b05

* lukas/erts/nodes_rwlock_contentions/OTP-11097: Change rwlock to rlock where possible
2013-05-16Change rwlock to rlock where possibleLukas Larsson
Having rwlock could cause high unneccesary contention on the dist table when calling erlang:nodes() from many schedulers at the same time.

2013-04-15erts: Remove unnecessary utf8 analysis step in external decodingSverker Eriksson
Faulty utf8 atoms are rejected anyway later when the atom is created.
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.
2013-04-11erts: Change locking order for "port_table" and "port_sched_lock"Sverker Eriksson
Keep order between the two but move them before all the allocation locks. Old order violated for "port_table" lock in ptab_list_bif_engine().

* rickard/thr_prgr_later_op/OTP-10994: Make port close not be delayed Be less eager requesting wakeup for cleanup jobs
2013-04-04Make port close not be delayedPatrik Nyblom
Drivers are dereferenced when the port is completely gone, in the operation scheduled with erts_schedule_thr_prgr_later_op. If we use erts_schedule_thr_prgr_later_cleanup_op, it may not happen for a long time and the driver can not be unloaded. We can not dereference the driver before the thread_progress_later thing, because references to the driver may exist in other threads, so the unloading of the driver may free locks held by other schedulers and whatnot.
