* rickard/ds-sched-suspend: Improved scheduler suspend functionality
2016-03-10Improved scheduler suspend functionalityRickard Green
- The calling process is now suspended while synchronizing scheduler suspends via erlang:system_flag(schedulers_online, _) and erlang:system_flag(multi_scheduling, _), instead of blocking the scheduler thread in the BIF call waiting for the operation to synchronize. Besides releasing the scheduler for other work (or immediate suspend) it also makes it possible to abort the operation by killing the process. - erlang:system_flag(schedulers_online, _) now only wait for normal schedulers to complete before it returns. This since it may take a very long time before all dirty schedulers suspends. - erlang:system_flag(multi_scheduling, block_normal|unblock_normal) which only operate on normal schedulers has been introduced. This since there are use cases where suspend of dirty schedulers are not of interest (hipe loader). - erlang:system_flag(multi_scheduling, block) still blocks all dirty schedulers as well as all normal schedulers except one since it is hard to redefine what multi scheduling block means. - The three operations: - changing amount of schedulers online - blocking/unblocking normal multi scheduling - blocking/unblocking full multi scheduling can now be done in parallel. This is important since otherwise a full multi scheduling block would potentially delay the other operations for a very long time.

Just mask away the high bits to get a more tolerant erlang:halt that behaves the same on 32 and 64 bit architectures.

2016-02-23erts: Make literal_alloc documented and configurableSverker Eriksson
Except it cannot be disabled and cannot be multi-threaded. The bit-vector 'erts_literal_vspace_map' on 32-bit is currently only protected by the literal allocator mutex. We could allow multiple instances on 64-bit (I think), but what would be the point?
2016-02-10epmd: support IPv6 node registrationMichael Santos
Allow IPv6 nodes to register with and query epmd. On systems with IPv6 support: * epmd listens on both the IPv4 and IPv6 ANY or loopback sockets * the epmd cli client connects to epmd over the IPv6 loopback * distributed nodes started with "-proto_dist inet6_tcp" will register with epmd over IPv6 To work on IPv6 capable systems that have IPv6 support disabled, epmd ignores errors opening the socket if the protocol is not supported. Similarly, the epmd client will fall back to IPv4 if the IPv6 socket is not available. Update the minimum supported version of Windows to Windows Vista to support IPv6.

2016-02-02erts: Add microstate accountingLukas Larsson
Microstate accounting is a way to track which state the different threads within ERTS are in. The main usage area is to pin point performance bottlenecks by checking which states the threads are in and then from there figuring out why and where to optimize. Since checking whether microstate accounting is on or off is relatively expensive if done in a short loop only a few of the states are enabled by default and more states can be enabled through configure. I've done some benchmarking and the overhead with it turned off is not noticible and with it on it is a fraction of a percent. If you enable the extra states, depending on the benchmark, the ovehead when turned off is about 1% and when turned on somewhere inbetween 5-15%. OTP-12345
2016-02-02erts, kernel: Add os:perf_counter functionLukas Larsson
The perf_counter is a very very cheap and high resolution timer that can be used to timestamp system events. It does not have monoticity guarantees, but should on most OS's expose a monotonous time. A special instruction has been created for this counter to further speed up fetching it. OTP-12908
