2014-02-28Add ETHR_FORCE_INLINE define to hide compiler specific directivesJani Hakala
Some win32 specific code does not compile with gcc (mingw-w64) since '__forceinline' is not supported by gcc. This can be avoided by defining a new macro ETHR_FORCE_INLINE similar to ETHR_INLINE.

2014-02-24ose: Thread priorities configurable from lmconfLukas Larsson
The pattern used for getting the priority from the lmconf is based on the name of the process created. The pattern is: ERTS_%%PROCESS_NAME%%_PRIO with the %%PROCESS_NAME%% replaced by the prefix of the process the priority applies to. eg: ERTS_SCHEDULER_PRIO=24 applies to processes with name SCHEDULER_1, SCHEDULER_2 etc.
2014-02-24ose: Start using ppdata for tse keyLukas Larsson
2014-02-24ose: Remove receive in debugLukas Larsson
Sometimes scheduler 1 should go in here and it will have signals, so remove this. If needed later a check to see that fsem is used for scheduler 1 is needed.

2014-02-24ose: OSE port related cleanup and fixesJonas Karlsson
Some OSE cross-chains have problems with system includes being used, so for atleast OSE specific parts we use "" instead of <>.
2014-02-24ose,erts: Specify name for tsd keysLukas Larsson
This simplified debugging on OSE and also limits the number of ppdata keys that are created when beam is restarted.
2014-02-24ose: Fix various build environment issuesLukas Larsson
2014-02-24ose: Change get_envp to ose_get_ppdata for tsdLukas Larsson
There is a system limit on the number of ppdata that is available but that should not be reached, and ppdata is faster than using get_envp.
2014-02-24ose: Change start way to use arguments to beam.smp directlyLukas Larsson
The old way registered a shell command that needed to be executed. This way is more flexible as you can also use the lmconf file to set arguments there.
2014-02-24ose: Debug wait__ does receive_fsem instead of wait_fsemLukas Larsson
This is done in order to catch rogue signals
2014-02-24Added support for ENEA OSELukas Larsson
This port has support for both non-smp and smp. It contains a new way to do io checking in which erts_poll_wait receives the payload of the polled entity. This has implications for all linked-in drivers.
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.

2013-01-15Implement ./otp_build configure --enable-silent-rulesAnthony Ramine
With silent rules, the output of make is less verbose and compilation warnings are easier to spot. Silent rules are disabled by default and can be disabled or enabled at will by make V=0 and make V=1.

2012-03-15erts: Fix memory corruption when reading topology infoSverker Eriksson
If the number of processors actually found while reading sysfs is lower than the configured value, we realloc() the cpuinfo array to the smaller size, but we then iterate it using the original configured size, thus corrupting memory beyond the allocated block.
