* sv-sched-percentage-option: add erl option to set schedulers by percentages OTP-11282
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.

2013-08-27erts: Fix segfault when scheduling release_port later_opLukas Larsson
begin_port_cleanup can be called from a non-scheduler thread, this means that there is no esdp available and thus erts_schedule_thr_prgr_later_op segfaults.

2013-08-23Create better distribution of files over async threadsPatrik Nyblom
The actual port id is used to create a key from the pointer value which is the ErlDrvPort. To do this a new driver api function driver_async_port_key is added and the driver API minor version is updated. The documentation is updated and the faulty description of how to spread ports over async threads is updated to use the new API. Testcase also added.

2013-08-15Workaround TR gnu/181328, GCC 4.2.1 20070831 on FreeBSD 9.1Patrik Nyblom
The bug manifests so that initialization of an automatic variable happens after a pointer to the variable is dereferenced, causing build_exec_return to take the wrong branch by default. The bug is verified to happen even outside the VM and is reported to FreeBSD as trouble ID gnu/181328. The workaround is a slight code rewrite which is optimized differently. Also removed two warnings about dereferencing type-punned pointers, which did not affect the bug.

Just some clarifying comments to future progremmers to keep the relation between error returns from the two functions.
2013-08-09Add match_limit and match_limit_recursion optionsPatrik Nyblom
Added to re:run and sets the corresponding fields in 'extra' struct for the PCRE match engine. The result can be viewed by also setting 'report_errors' when matching. Some housekeeping was also done... The offset option also did not properly check for offset's >= 0. Change nomatch to BADARG when pre-compiled mp() is faked: By constructing a 5-tuple with faked content but the right data types, you could do a re:run which returned nomatch when in fact the mp() was bad. The cheapest solution is to check the return from pcre_exec better. Remove unreachable code in erts_bif_re.c: Replaced tests for things that logically simply cannot happen with ASSERT.
