I'd suggest looking at how GROMACS does it, for example: https://github.com/gromacs/gromacs/blob/master/src/gromacs/timing/cyclecounter.h Do note that the mrrc instruction on ARMv7 will fail with SIGILL, because it's a kernel-mode instruction: https://redmine.gromacs.org/issues/1933 Regards, Dominik -- Fedora http://fedoraproject.org/wiki/User:Rathann RPMFusion http://rpmfusion.org "Faith manages." -- Delenn to Lennier in Babylon 5:"Confessions and Lamentations" -- devel mailing list devel@lists.fedoraproject.org https://lists.fedoraproject.org/admin/lists/devel@lists.fedoraproject.org
