2015-07-10ose: Remove all code related to the OSE portLukas Larsson
The OSE port is no longer supported and this commit removed it and any changes related to it. The things that were general improvements have been left in the code.

2015-06-16erts: Do not preallocate too large event poolBjörn-Egil Dahlberg
A pool size of 4000 is too excessive for the common case. Change ERTS_TS_EV_ALLOC_DEFAULT_POOL_SIZE to 2048 Change ERTS_TS_EV_ALLOC_POOL_SIZE to 32

* lukas/erts/non-blocking-shell: erts: Fix big-endian issue with printf_putc
2014-12-15erts: Fix big-endian issue with printf_putcLukas Larsson
On little-endian machines, doing &int will give the smallest byte which is what we want to give to write. But on big-endian it will give the highest byte, which will always be \000 here which results in write never doing any writes. So we have to cast c to an unsigned char before passing it to write.

2014-11-04erts: Make erts_printf work with non-blockingLukas Larsson
Now that stdout can be set as non-blocking by the ttsl driver we can no longer use putc and friends for the stdout/stderr streams. Therefore we fallback on write. OTP-12239
2014-10-19Fix bug in FreeBSD topology detection codePaul Guyot
Code incorrectly relied on undefined C behavior. Clang and gcc 4.9 do not behave as code expected. This affected cores and processors detection on FreeBSD.
2014-06-30erts: Separate ethread inlining from ethread.hBjörn-Egil Dahlberg
The commit adb5dc0090bc419e2c4c1250653badbddeb6263b (ETHR_FORCE_INLINE) broke some platforms without adequate thread support.

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.

2014-02-24Added 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.

2012-10-10erts: Fix '#ifdef' for unused static functionsBjörn-Egil Dahlberg
On architectures where cpu topology was unavailable, warnings erupted due to unused static functions. Those warnings are now silenced.

Add probes to the virtual machine, except (mostly) the efile_drv.c driver and other file I/O-related source files.
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.
