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.

2015-05-21Add architecture ppc64le architecture as a ppc64Breno Leitao
ppc64le is a new arch/ABI that runs on IBM POWER processor starting at POWER8 processor, and it should be listed as a ppc64, mainly for hipe enablement. For more information about this new arch/ABI, please check the documents at: https://www-03.ibm.com/technologyconnect/tgcm/TGCMServlet.wss?alias=OpenPOWER

2015-05-06erts: Disable float exceptions for clang/llvmMikael Pettersson
Change erts/configure.in to force-disable FP exceptions if the VM is compiled by clang/llvm. clang/llvm generates FP code which does not work with FP exceptions (whether unmasked as used in the Erlang VM, or masked followed by tests of which are signalled). This is a known long-standing problem.
2015-05-05erts: Fix configure.inBjörn-Egil Dahlberg
Don't repeat cpu_sup in os_mon_programs - some OS gets confused, i.e. illumos.

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.
2015-04-13erts: Add high accuracy poll timeoutsLukas Larsson
Different poll/select implementations have different ways to handle timeouts of < ms accuracy. Most have extended API like pselect or such, while others rely on using timerfds (epoll_wait). If no high accuracy timeout is available, we simply round up to nearest ms. If we do not roundup we will spin the last ms when waiting for a timeout which is not desirable.

* rickard/gcc-atomics/OTP-12383: Improve ethread atomics based on GCC builtins Conflicts: erts/aclocal.m4
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.

2014-12-29os_mon: cpu_sup should use native sysctl/libkvm calls on BSDAlex Wilson
This avoids forking off with os:cmd every time we just want to collect the load averages. riak does this every second, which results in a lot of unnecessary load.
