2015-04-20erts/configure.in: handle more 'linux' spellingsMikael Pettersson
The configuration code which canonicalizes the operating system name into OPSYS requires Linux to be spelled 'linux' or 'Linux'. This is a problem in some build environments, e.g. RPM, which supply --build and --host using the longer 'linux-gnu' spelling. The effect is that OPSYS becomes 'noopsys' and some checks in erts/configure.in do not work as expected, e.g. the auto-enabling of HiPE may not happen. Fixed by matching on 'linux*' not just 'linux'. On ARM there are even longer variants such as 'linux-gnueabi' and 'linux-gnueabihf': these are also correctly mapped to 'linux' now.

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.

2015-01-14Improve ethread atomics based on GCC builtinsRickard Green
* Use of __atomic builtins when available. * Improved configure test that checks for missing memory barrier in __sync_synchronize(). The old approach was to verify known working gcc versions and check gcc version at compile time. Besides not being very safe, the old approach often unnecessarily caused usage of the very expensive workaround. * Introduced (no overhead) workaround for missing clobber in __sync_synchronize() when using buggy LLVM implementation of __sync_synchronize(). * Implement native memory barriers for ARM processors supporting the DMB instruction. * Use of volatile store on Alpha as atomic set operation if no __atomic_store_n() is available (already used on x86/x86_64 Sparc V9, PowerPC, and MIPS). Fallback used when not using volatile store is typically very expensive. * Use volatile load on Alpha and ARM as atomic read operation if no __atomic_load_n() is available (already used on x86/x86_64 Sparc V9, PowerPC, and MIPS). Fallback when not using volatile load is typically very expensive.

* vinoski/ds2: further enhancements for dirty schedulers allow optional whitespace in dirty scheduler erl options
2014-02-24further enhancements for dirty schedulersSteve Vinoski
Add support for setting the number of dirty CPU schedulers online via erlang:system_flag/2. Assuming the emulator is built with dirty schedulers enabled, the number of dirty CPU schedulers online may not be less than 1, nor greater than the number of dirty CPU schedulers available, nor greater than the number of normal schedulers online. Dirty CPU scheduler threads that are taken offline via system_flag/2 are suspended. The number of dirty CPU schedulers online may be adjusted independently of the number of normal schedulers online, but if system_flag/2 is used to set the number of normal schedulers online to a value less than the current number of normal schedulers online, the number of dirty CPU schedulers online is decreased proportionally. Likewise, if the number of normal schedulers online is increased, the number of dirty CPU schedulers online is increased proportionally. For example, if 8 normal schedulers and 4 dirty CPU schedulers are online, and system_flag/2 is called to set the number of normal schedulers online to 4, the number of dirty CPU schedulers online is also decreased by half, to 2. Subsequently setting the number of normal schedulers online back to 8 also sets the number of dirty CPU schedulers online back to 4. Augment the system_flag/2 documentation in the erlang man page to explain this relationship between schedulers_online and dirty_cpu_schedulers_online. Also ensure that all dirty CPU and I/O schedulers are suspended when multi-scheduling is blocked via system_flag/2, and brought back online when multi-scheduling is unblocked. Add Rickard Green's rewritten check_enqueue_in_prio_queue() function that inspects process state more thoroughly to determine if to enqueue it and if so on what queue, including dirty queues when appropriate. Make sure dirty NIF jobs do not trigger erlang:system_monitor long_schedule messages. Add more dirty scheduler testing to the scheduler test suite. Remove the erts_no_dirty_cpu_schedulers_online global variable, since it's no longer needed. Execute dirty NIFs on a normal scheduler thread while multi-scheduling blocking is in effect. Evacuate any dirty jobs residing in the dirty run queues over to a normal run queue when multi-scheduling is blocked. Allow dirty schedulers to execute aux work. Set the dirty run queues halt_in_progress flag when halting the normal schedulers. Change dirty scheduler numbers to a structure including both scheduler number and type, either dirty CPU or dirty I/O. Add some assertions to ensure that dirty CPU schedulers operate only on dirty CPU scheduler process flags, and the same for dirty I/O schedulers.

* vinoski/ds: initial support for dirty schedulers and dirty NIFs
2014-01-28initial support for dirty schedulers and dirty NIFsSteve Vinoski
Add initial support for dirty schedulers. There are two types of dirty schedulers: CPU schedulers and I/O schedulers. By default, there are as many dirty CPU schedulers as there are normal schedulers and as many dirty CPU schedulers online as normal schedulers online. There are 10 dirty I/O schedulers (similar to the choice of 10 as the default for async threads). By default, dirty schedulers are disabled and conditionally compiled out. To enable them, you must pass --enable-dirty-schedulers to the top-level configure script when building Erlang/OTP. Current dirty scheduler support requires the emulator to be built with SMP support. This restriction will be lifted in the future. You can specify the number of dirty schedulers with the command-line options +SDcpu (for dirty CPU schedulers) and +SDio (for dirty I/O schedulers). The +SDcpu option is similar to the +S option in that it takes two numbers separated by a colon: C1:C2, where C1 specifies the number of dirty schedulers available and C2 specifies the number of dirty schedulers online. The +SDPcpu option allows numbers of dirty CPU schedulers available and dirty CPU schedulers online to be specified as percentages, similar to the existing +SP option for normal schedulers. The number of dirty CPU schedulers created and dirty CPU schedulers online may not exceed the number of normal schedulers created and normal schedulers online, respectively. The +SDio option takes only a single number specifying the number of dirty I/O schedulers available and online. There is no support yet for programmatically changing at run time the number of dirty CPU schedulers online via erlang:system_flag/2. Also, changing the number of normal schedulers online via erlang:system_flag(schedulers_online, NewSchedulersOnline) should ensure that there are no more dirty CPU schedulers than normal schedulers, but this is not yet implemented. You can retrieve the number of dirty schedulers by passing dirty_cpu_schedulers, dirty_cpu_schedulers_online, or dirty_io_schedulers to erlang:system_info/1. Currently only NIFs are able to access dirty scheduler functionality. Neither drivers nor BIFs currently support dirty schedulers. This restriction will be addressed in the future. If dirty scheduler support is present in the runtime, the initial status line Erlang prints before presenting its interactive prompt will include the indicator "[ds:C1:C2:I]" where "ds" indicates "dirty schedulers", "C1" indicates the number of dirty CPU schedulers available, "C2" indicates the number of dirty CPU schedulers online, and "I" indicates the number of dirty I/O schedulers. Document The dirty NIF API in the erl_nif man page. The API closely follows Rickard Green's presentation slides from his talk "Future Extensions to the Native Interface", presented at the 2011 Erlang Factory held in the San Francisco Bay Area. Rickard's slides are available online at http://bit.ly/1m34UHB . Document the new erl command-line options, the additions to erlang:system_info/1, and also add the erlang:system_flag/2 dirty scheduler documentation even though it's not yet implemented. To determine whether the dirty NIF API is available, native code can check to see whether the C preprocessor macro ERL_NIF_DIRTY_SCHEDULER_SUPPORT is defined. To check if dirty schedulers are available at run time, native code can call the boolean enif_have_dirty_schedulers() function, and Erlang code can call erlang:system_info(dirty_cpu_schedulers), which raises badarg if no dirty scheduler support is available. Add a simple dirty NIF test to the emulator NIF suite.

2014-01-17configure: Prefer the system's zlib over own our zlib sourceBjörn Gustavsson
WxWidgets (used by the wx application) also uses zlib. To ensure that the run-time system and WxWidgets use the same version of zlib, use the system's zlib if present. Also, the system's zlib may be specially optimized and thus faster than our own generic source code. We only use zlib versions that are "good enough". For now, that means 1.2.5 or higher. Remove the option --enable-shared-zlib and add the option --enable-builtin-zlib to force the use of the built-in zlib.
