2017-10-02erts: Add multiple poll setsSverker Eriksson
2017-09-15erts: Refactor check_io to use one static structSverker Eriksson
that is shared between _kp and _nkp versions. Makes it easier to access in debugger.

2017-09-15erts: Rename ErtsPollSet_ structS to not confuse gdbSverker Eriksson
by having different structs with same name.
2017-09-15erts: Increase number of check_io-fd-locksSverker Eriksson
and use correct cache alignment.
2017-07-17erts: Replace usage of all erts_smp prefixes to just ertsLukas Larsson
2017-07-17erts: Cleanup removal of non-smp emulatorsLukas Larsson
2017-07-17erts: Remove ERTS_SMP and USE_THREAD definesLukas Larsson
This refactor was done using the unifdef tool like this: for file in $(find erts/ -name *.[ch]); do unifdef -t -f defile -o $file $file; done where defile contained: #define ERTS_SMP 1 #define USE_THREADS 1 #define DDLL_SMP 1 #define ERTS_HAVE_SMP_EMU 1 #define SMP 1 #define ERL_BITS_REENTRANT 1 #define ERTS_USE_ASYNC_READY_Q 1 #define FDBLOCK 1 #undef ERTS_POLL_NEED_ASYNC_INTERRUPT_SUPPORT #define ERTS_POLL_ASYNC_INTERRUPT_SUPPORT 0 #define ERTS_POLL_USE_WAKEUP_PIPE 1 #define ERTS_POLL_USE_UPDATE_REQUESTS_QUEUE 1 #undef ERTS_HAVE_PLAIN_EMU #undef ERTS_SIGNAL_STATE
2017-07-06Allow toggling lock counting at runtimeJohn Högberg
The implementation is still hidden behind ERTS_ENABLE_LOCK_COUNT, and all categories are still enabled by default, but the actual counting can be toggled at will. OTP-13170
2017-05-04Update copyright yearRaimo Niskanen
2017-04-27Rename macro and add clarifying commentRichard Carlsson
The macro previously named 'LOG2' is in fact computing the LSB (not the MSB) of its input, and can only be used to compute log2(n) when n is is a power of 2, that is, when its LSB is also its MSB.

2017-04-20erts: Fix new gcc warning in check ioLukas Larsson
2017-03-22erts: Don't allocate memory during signal handlingBjörn-Egil Dahlberg
Allocations and message sending are now scheduled by a signal, via a signal state bitmap, instead of doing it directly in the signal handler.
2017-03-21erts: Make sigterm signal safe for non-smp beamBjörn-Egil Dahlberg
The signal handler will now schedule a sigterm message instead of sending the message in the signal handler. The signal handler must refrain from memory allocations and thus the event is scheduled.

2017-02-20Remove faulty debug ASSERTSverker Eriksson
Why did I add that?

2017-02-14Fixed typos in ertsAndrew Dryga
2017-02-09erts: Try fix enif_select for windowsSverker Eriksson
by simply disable "delayed deselect".
2017-02-09erts: Change return value for enif_selectSverker Eriksson
to negative int as error and positive as success.
2017-02-09erts: Add pid argument to enif_selectSverker Eriksson
2017-02-09erts: Beautify enif_selectSverker Eriksson
indentation and comments only
2017-02-09erts: Fix bad_fd_in_pollset error case for enif_selectSverker Eriksson
2017-02-09erts: Add enif_monitor_process and enif_demonitor_processSverker Eriksson
2017-02-03erts: Rename ErlNifResource as ErtsResourceSverker Eriksson
as it's not part of the API

2016-12-19Add ErlNifSelectReturnSverker Eriksson
2016-12-19Add stop arguments: fd and is_direct_callSverker Eriksson
2016-12-19erts: Add testing + some minor fixesSverker Eriksson
2016-11-30erts: Add enif_select & enif_open_resource_type_xSverker Eriksson
2016-11-28erts: Rename some static functionSverker Eriksson
2016-11-28erts: Refactor add_active_fdSverker Eriksson
to not inline cold reallocation code.
2016-11-28erts: Change handling of error event for driver_selectSverker Eriksson
Make the code simpler. May change the behavior as we may call both iready and oready when getting an error. But doesn't that seem more correct.
2016-11-22Merge branch 'maint'Sverker Eriksson
2016-11-17erts: Fix all -Wundef errorsSverker Eriksson
2016-11-17erts: Refactor crash dumping with cbprintfSverker Eriksson
Instead of passing around a file descriptor use a function pointer to facilitate more advanced backend write logic such as size limitation or compression.
2016-10-21erts: Use mprotect for hipe on all arch except x86_64Sverker Eriksson
Only x86_64 needs to reserve low virtual memory for its amd64 small code model.
2016-10-14erts: Enable exec_alloc for all hipe architecturesSverker Eriksson
For non-amd64 it's a "normal" allocator with a wrapper around mseg_alloc to call mprotect(PROT_EXEC).
2016-06-22Improve accuracy of timeouts using premature timeoutsRickard Green
Improve accuracy of timeouts using a premature timeout then return to sleep with a shorter timeout just before requested timeout. This approach is only used on certain platforms where we know it improves the accuracy of the timeouts, e.g. MacOS X.
2016-06-10Disregard MAP_NORESERVE for FreeBSDKenji Rikitake
A fix for running 19.0-rc2 on FreeBSD with HiPE enabled. * erl_mmap.h: disregard MAP_NORESERVE for FreeBSD MAP_NORESERVE is undefined in FreeBSD 10.x and later. This is to enable 64bit HiPE experimentally on FreeBSD. Note that on FreeBSD MAP_NORESERVE was "never implemented" even before 11.x (and the flag does not exist in /usr/src/sys/vm/mmap.c of 10.3-STABLE r301478 either), and HiPE was working on OTP 18.3.3, so mandating MAP_NORESERVE on FreeBSD might not be needed. See the following message on how MAP_NORESERVE was treated on FreeBSD: <http://lists.llvm.org/pipermail/cfe-commits/Week-of-Mon-20150202/122958.html> * erl_mmap.c: disable MAP_NORESERVE for FreeBSD * See also <https://github.com/erlang/otp/pull/925/commits/b02ce940c8738785ad018c9f758ca0d05d256bbb>
