2013-09-11Fix syslog definesMatt Lewandowsky
config.h defines HAVE_SYSLOG_H whereas the sources are looking for NO_SYSLOG to be undefined. As the logic of "if feature is available" makes more sense than "if feature is not unavailable", I opted for the config.h define.

* maint: add erl option to set schedulers by percentages
2013-08-29add erl option to set schedulers by percentagesSteve Vinoski
For applications where measurements show enhanced performance from the use of a non-default number of emulator scheduler threads, having to accurately set the right number of scheduler threads across multiple hosts each with different numbers of logical processors is difficult because the erl +S option requires absolute numbers of scheduler threads and scheduler threads online to be specified. To address this issue, add a +SP option to erl, similar to the existing +S option but allowing the number of scheduler threads and scheduler threads online to be set as percentages of logical processors configured and logical processors available, respectively. For example, "+SP 50:25" sets the number of scheduler threads to 50% of the logical processors configured, and the number of scheduler threads online to 25% of the logical processors available. The +SP option also interacts with any settings specified with the +S option, such that the combination of options "+S 4:4 +SP 50:50" (in either order) results in 2 scheduler threads and 2 scheduler threads online. Add documentation for the +SP option. Add tests for the +SP option to scheduler_SUITE. Add tests and documentation for two existing features of the +S option: +S 0:0 resets the scheduler thread count and scheduler threads online count to their defaults, and specifying negative numbers for +S results in those values being subtracted from the default values for the host.
2013-08-23erts: Speed up valgrind with asynch threadsSverker Eriksson
by only letting it run on one core. Valgrind only let one thread at a time execute anyway.

* sze/to_erl/OTP-11206: Fix changing terminal parameters in to_erl
2013-07-22Fix changing terminal parameters in to_erlStefan Zegenhagen
One of our devices does not like 'to_erl' to be run over a serial port. When to_erl is started, we see "Attaching to /tm<0xFF>" being printed and the device then refuses to accept any input. Occasionally, we have seen a linux kernel error message "serial8250: too much work for irq16" simultaneously. After some debugging we found out that cause is a call to tcsetattr() by to_erl, immediately preceeded by some printf(). The UART in our device doesn't like hardware parameters to be changed while output is concurrently active. In fact, the GNU libc manual also mentions that it might be dangerous to change UART hardware parameters when a transmission is ongoing. The patch attached to this e-mail changes the behaviour of to_erl to use TCSADRAIN instead of TCSANOW when changing terminal parameters. This makes the serial driver wait for the output queues to be empty before applying the terminal parameter change.

Like in epmd and erlexec. Otherwise "run_erl" fails on some platforms when called with the "-daemon" option, printing this error: "Cannot dup"

* maint: erts: Add the +sfwi system flag
2013-06-11erts: Add the +sfwi system flagRickard Green
+sfwi Interval Set scheduler forced wakeup interval. All run queues will be scanned each Interval milliseconds. While there are sleeping schedulers in the system, one scheduler will be woken for each non-empty run queue found. An Interval of zero disables this feature, which also is the default. This feature has been introduced as a temporary workaround for lengthy executing native code, and native code that do not bump reductions properly in OTP. When these bugs have be fixed the +sfwi flag will be removed.
