* rickard/rm-common-runq/OTP-9727: Remove common run-queue in SMP case Fix scheduler suspend bug Conflicts: erts/emulator/beam/erl_init.c
2011-12-01Deprecate erlang:system_flag/2 arguments scheduler_bind_type and cpu_topologyRickard Green
The use of erlang:system_flag(scheduler_bind_type, _) and erlang:system_flag(cpu_topology, _) have been deprecated and scheduled for removal in erts-5.10/OTP-R16. For more information see the documentation of erlang:system_flag/2.
2011-12-01Remove common run-queue in SMP caseRickard Green
The common run-queue implementation is removed since it is unused, untested, undocumented, unsupported, and only complicates the code. A spinlock used by the run-queue management sometimes got heavily contended. This code has now been rewritten, and the spinlock has been removed.
2011-12-01Fix scheduler suspend bugRickard Green
Calls to erlang:system_flag(schedulers_online, N) and/or erlang:system_flag(multi_scheduling, block|unblock) could cause internal data used by this functionality to get into an inconsistent state. When this happened various problems occurred. This bug was quite hard to trigger, so hopefully no-one has been effected by it.

2011-11-30erts: Warn the first time a tuple fun is calledBjörn Gustavsson
2011-11-29big_SUITE: Eliminate use of tuple funBjörn Gustavsson
It seems that a tuple fun was used only because erl_eval:expr/3 did not support passing in a real fun at the time that the test case was originally written.

Also use 64-bit lib when necessary, specify runtime lib path for secondary dependency libs, and better check before using SIOCGIFHWADDR.
2011-11-29Merge branch 'bjorn/erts/remove-useless-variable'Björn Gustavsson
* bjorn/erts/remove-useless-variable: erl_process.c: Remove the redundant variable 'processes_busy' Update primary bootstrap otp_internal: Deprecate ssl:pid/1
2011-11-29erl_process.c: Remove the redundant variable 'processes_busy'Björn Gustavsson
There is a static variable called 'processes_busy' in erl_process.c, which will be incremented but never used. To confuse things, there is also a global variable with the same name, but it it is only defined and used if BM_COUNTERS is defined. In erl_process.c, the global version of 'processes_busy' will be seen and incremented if BM_COUNTERS is defined. Remove the static version of 'processes_busy' in erl_process.c, but keep the global version if BM_COUNTERS is defined. Noticed-by: Jovi Zhang

2011-11-26beam_load.c: Add init_iff_file() for verifying the IFF headerBjörn Gustavsson
Add init_iff_file() for verifying the IFF header. Also let it handle compressed BEAM files so that it will be done in one place. That means that code:get_chunk/2 and code:module_md5/1 will now support compressed BEAM files.
2011-11-26beam_code.c: Don't reinvent state initialization and deallocationBjörn Gustavsson
2011-11-26beam_load.c: Optimize code:get_chunk/2Björn Gustavsson
The undocumented code:get_chunk/2 BIF is supposed to be a fast way to extract a chunk from a BEAM file when loading native code. In practice, it might not have been faster because it happened to calculate an MD5 checksum for the chunk it extracted because it shared the scan_iff_file() function with the erlang:load_module/2 BIF. Split scan_iff_file() into scan_iff_file() and verify_chunks(), so that the unnecessary MD5 calculation can be avoided.
2011-11-26beam_load.c: Eliminate memory leak in code:make_stub_module/3Björn Gustavsson
code:make_stub_module/3 leaked memory if given either a corrupt BEAM file, or a compressed BEAM file and an error occurred, or a binary not aligned on byte boundaries.
2011-11-25Fix clang linking problemBjörn Gustavsson
Inlining was not done in a portable way. clang follows the C99 semantics for inlining ('inline' essentially implies 'static' in C99, but not in GCC), so bp_sched2ix() was not visible outside beam_bp.c. Since the function need to be used from more than one source file, put the function definition in the beam_bp.h header file. Also, give it an 'erts_' prefix since it is globally visible.

2011-11-18Use unbound schedulers as defaultRickard Green
As of ERTS version 5.9 (OTP-R15B) the runtime system will by default not bind schedulers to logical processors. If the Erlang runtime system is the only operating system process that binds threads to logical processors, this improves the performance of the runtime system. However, if other operating system processes (as for example another Erlang runtime system) also bind threads to logical processors, there might be a performance penalty instead. In some cases this performance penalty might be severe. Due to this, we change the default so that the user must make an active decision in order to bind schedulers.

The spinlocks used implementing pix-locks have been replaced with mutexes since they perform better during heavy contention.
