2015-02-19remove perfctr supportMikael Pettersson
Perfctr is a Linux kernel extension that allows programmatic access to the performance monitoring counters found in most current CPUs. However, development of perfctr ceased after 2010, and it cannot be used with Linux kernels newer than 2.6.32. Therefore the perfctr support code in the Erlang VM is effectively dead code, so this patch removes it.

2015-01-23erts: Check driver version before assigning callbackBjörn-Egil Dahlberg
2015-01-23erts: Don't lookup invalid port for crashdump handlingBjörn-Egil Dahlberg
2015-01-23erts: Use emergency close to close epmdBjörn-Egil Dahlberg
Closes all open socket before writing crashdump to file.
2015-01-14Add math:log2/1Olivier Girondel
2015-01-13erts: Extend driver interface with emergency_closeBjörn-Egil Dahlberg
The intention of this callback is to close all sockets associated to a port. It is closed only on crashdumps. This will currently only be used for the epmd port.

* lukas/erts/crashdump_improvements/OTP-12377: erts: Make main thread safe from pipe closed event erts: Improve crash dumps erts: Rename sys_sigset to sys_signal erts: Introduce thread suspend functions erts: Remove usage of QUANTIFY signal erts: Add support for thread names ets: Increase data available in crash dumps and ets:info erts: Start compilation of beam_emu earlier
2014-12-19erts: Improve crash dumpsLukas Larsson
This commit improves crash dumps in several ways: * Suspends schedulers to get a current snapshot * Dumps information about scheduler * Dumps stack trace of current running process (including Garbing processes)
2014-12-19erts: Introduce thread suspend functionsLukas Larsson
These functions allow any thread to suspend any other thread immediately and then resume all threads. This is useful when doing a crash dump in order to get a more accurate picture of what state the system is in.

2014-12-10Use the new 64-bit atomic ops APIRickard Green
2014-12-10Introduce a 64-bit atomic ops APIRickard Green
The 64-bit atomic ops API is implemented by * native word size atomic ops on 64-bit architectures, and * native double word size atomic ops on 32-bit architectures when available. When native double word size atomic is not available, the fallback using modification counters is used.

2014-12-05erts: Use linear search for small select_val arraysBjörn-Egil Dahlberg
For searching a key in an array we use linear search in arrays up to 10 elements. Selecting on tuple arity will always use linear search. Instead of using two different instructions we assume selecting on different tuple arities are always few in numbers.
