I mean that only online cores are shown in /proc/cpuinfo. So the PowerTOP doesn't count currently offline ones. And you must run the PowerTOP on a heavy loaded system to let the PowerTOP see all CPU cores. Therefore it is impossible to run the PowerTOP before starting of heavy application to get information about all CPU cores. Probably the PowerTOP could cache CPU information in some file, so it will be possible to register trace events for all cores. -- = Best regards, Igor Zhbanov, Expert Software Engineer, phone: +7 (495) 797 25 00 ext 3806 e-mail: i.zhbanov(a)samsung.com ASWG, Moscow R&D center, Samsung Electronics 12 Dvintsev street, building 1 127018, Moscow, Russian Federation --===============4798020587258524841==--
