* QtConcurrent: use QDeadlineTimer to get the clock tickThiago Macieira2016-09-151-73/+2
| | | | | | | | | | | | | | Instead of duplicating what QElapsedTimer & QDeadlineTimer already do. Well, technically speaking, we aren't getting ticks, but nanoseconds now, but the times are only used in comparisons with each other, to measure the control overhead, so the unit in which they are measured doesn't matter. This also makes all OSes use the same type of timers. There's no exception for per-thread timing. Change-Id: I115db302eb114bed8cd1fffd14557b228284f2c0 Reviewed-by: Marc Mutz <marc.mutz@kdab.com>

| * OpenBSD: use clock_gettime() provided by OSRalf Nolden2016-06-081-1/+1
| | | | | | | | | | | | | | | | | | The use of clock_gettime() is limited to systems having _POSIX_TIMERS defined, however OpenBSD implements clock_gettime() but does not have the posix define. Enable using clock_gettime() on OpenBSD as well. Change-Id: I785954fe61b42b15755ca625a766c9a95179ae8d Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>

* QtConcurrent::IterateKernel: fix a race on a cache variableMarc Mutz2013-09-261-3/+6
| | | | | | | | | | | | | | | | | getticks() can be called concurrently, so accessing a non-atomic static long, even when the assignment will produce the same value in evey case, constitutes a data race. Fixed by making 'useThreadCpuTime' atomic. Since atomic long's might not be supported on all platforms, use an atomic int instead. To avoid a narrowing conversion, and since we're not interested in the return value of sysconf(), only whether it succeeded, convert any non-error return value to 0 prior to storing in the atomic.
